Although I am traditionally regarded as a structural and metamorphic geologist, over the past ~5 years I have become increasingly interested in geodynamic modeling, and have done a great deal of work in both industry and academic focused on finite element modeling of salt basin evolution and wellbore geomechanics. Over the last ~3 years, my focus has shifted back to studies of mountain belt geodynamics, with a particular emphasis on understanding the thermal and mechanical evolution of these systems. My research group is now developing numerous major research studies that examine how erosion and the greater landscape response will influence (and be influenced by) the structural and thermal evolution of these systems, and how those effects may impact the system mechanical evolution. At UK, I am currently assembling a lab that includes computational clusters and mineral separation facilities to pursue a number of integrative and multidisciplinary structural, tectonic, and surface process studies that will include roughly equal parts numerical modeling and field/lab studies. Because I am an early career faculty member that is relatively new to this subdiscipline, this meeting would represent an ideal forum to meet members of the community and hopefully plant the seeds for new long-term collaborations. +
As a current PhD candidate, I am using the continental margin sediment record in Southeastern Alaska to investigate climate and tectonic interactions in the St. Elias Mountains and how these interactions impact where concentrated glacial erosion occurs. As the St. Elias is a young and tectonically active mountain range, the location where large amounts of mass are removed and then redeposited may have an impact on the overall tectonic structure of the range. Sediment provenance is used to investigate if climate or tectonic forces exert a greater control over the locus of glacial erosion. If climate has the greatest control, provenance varies between glacial and interglacial periods as glaciers advance onto the continental shelf and then retreat, if tectonic forces have the greatest influence, erosion should be consistently concentrated in regions of mechanically weakened rock (i.e. fault zones).
My interest in attending the CTSP meeting is two-fold. Firstly, I’d like to be able to share my research on climate-tectonic interactions in a glacial setting with the community by presenting a poster at the meeting. The paper on this project is in prep and will most likely not be published by the time of the meeting, making this information otherwise unavailable. As the goal of this meeting is to produce a white paper, having the most up to date research is critical. In addition, it will also present me with an opportunity to solicit feedback on my work before publishing. Secondly, I am nearing graduation and am beginning to look for postdoc positions. By attending this meeting I will be able to network with other scientists who share similar research interests, with whom I may be able to work with during a post-doc. Attendance will also help me better understand the direction that future climate-tectonic interaction research is headed, which will assist me in directing my future research. +
As an early career scientist focused on the interactions between geomorphology, tectonics and climate, I am interested in joining this workshop for the following reasons:
(a) I hope that this workshop will present opportunities to learn and share thoughts about recent progress in the field of modeling coupled interactions between geomorphologic and tectonic processes.
(b) The discussions about algorithm development for coupling between geomorphologic and tectonic processes, seems like a way to broaden my perspective on this coupling, as well as a mean to share thoughts about potential directions for such future developments.
(c) I am interested in developing topographic metrics and relations that capture the essence of landscape properties and facilitate comparisons between simulated and natural landscapes, thus promoting evaluation of model performance. I hope that this workshop will produce opportunities to discuss and develop this line of thinking in the context of coupled models.
(d) The workshop will likely present opportunities to develop collaborations. I am particularly interested in collaborations that bridge between local observations of geomorphologic processes and tectonic indicators to large scale topographic and tectonic patterns.
(e) I am developing a graduate class that combines landscape analysis and modeling of tecto-geomorphic processes and think that discussions within this workshop can help in shaping my thoughts regarding the best way to introduce students to the coupling of these processes. +
At present, I am working on the problem of the evolution of elevated passive continental margin like Western Ghats, India and understanding the process of metamorphism and evolution of metamorphic rocks etc., which are the areas of large scientific interest. The Western Ghats at the western margin of Peninsular India is made up of several regional provinces like Deccan Plateau (DP), Dharwar Craton (DC) and Southern Granulite Terrain (SGT) and also covers the southern province of peninsular India. These provinces are traversed by several shear zones separating the different crustal blocks and in the need of delineating the nature underneath the deep-seated structures. Therefore, detail integrated study need to be carried out for a better understanding of the settings of such zones that are important for tracing the tectonic history and their characteristics.
Hence, CTSP: Coupling of Tectonic and Surface Processes workshop is a golden opportunity to learn the tectonic and surface processes that affects the deformation as well as subsurface structures upto a great depth. It also provides me a foremost opportunity to start a long lasting personal relation with CSDMS community. I am happy to be a part of it.
Thank you. +
Being a researcher in geomorphology, I am particularly interested in the Tectonic geomorphology and Quaternary geomorphology. In last 5 years, I am working in North-east India on a Chittagong Tripura Fold Belt that possesses Ridge and valley topography. The soft sedimentary deformation structure and thrust faults are prominent in this region that is the major interest of my research. +
Being an early career scientist as a Research Associate and upcoming position as a Postdoc, this workshop will provide an opportunity to network and potential develop future research collaborations in this field. The topics covered in this workshop are very well in line with my research interests. Some of the key driving research questions that I am particularly interested include the feedback mechanisms between active tectonics, erosion, climate, and landscape evolution which affect mountain building processes. +
CSDMS is the leader in community-based model integration to explore longstanding questions about the dynamics of our Earth. I am interested in sharing my own contributions at this unprecedented event: linking deformational processes deep within the listhosphere, brittle failure and erosion of bedrock by diverse surface processes, and dynamic responses of climate to constantly evolving topographic patterns, all of which are distributed heterogeneously in space and time. Additionally I am interested in sharing some new innovations with topographic pattern recognition: using machine learning techniques to diagnose historic or presently active tectonic/surface processes based on landscape topology. I am excited at the prospect of rejoining some of my old colleagues and building new friendships through a diversity of collaborations that will emerge at this meeting. I look forward to contributing to these longstanding, interdisciplinary relationships for years to come. Thank you for your consideration! +
Currently a second-year MS student at the University of Kentucky (advisor Ryan Thigpen), I'm researching the fundamental geodynamic mechanisms responsible for shortening accommodation and mass redistribution in large continental collisional systems. I use numerical modeling (Elfen FE) coupled with field and laboratory (metamorphic petrology) data collected from the Himalaya. I will start a Ph.D. next year (advisor Kip Hodges) and my dissertation will be focused on combining that background in modeling thermal-rheological evolution of the subsurface lithosphere with climate-modulated erosion processes and landscape dynamics using a combination of numerical modeling, field mapping, and chronologic datasets derived from samples collected in the field. This workshop will help me explore existing and developing computational infrastructure that will assist with that research. It will also allow me to network with others working on similar and/or complementary problems. +
Dear members of the organizing committee,
I'm currently working in Jean Braun's Earth Surface Processes Modelling group at GFZ Potsdam, and in this application I would like to express my great interest in attending the CTSP Meeting that will be held on April 2018 in Boulder.
One of the main objectives in our research group is to develop a state-of-the-art model of landscape evolution with very efficient numerical methods to simulate it over long time-scales and to allow exhaustive exploration of model behavior.
Our motivation is to better understand how landscape evolution responds to external forcing such as tectonic activity or variations in climate. One big, open challenge is indeed how can we efficiently and accurately couple tectonic and surface processes in models, which requires dealing with multiple length and time scales. The CTSP Meeting represents a great opportunity for us to share our thoughts with experts in the field on how best we can tackle this issue.
More specifically, as a research software engineer I'm working on different projects including a modular library of efficient algorithms for landscape evolution modeling as well as a generic framework that allows fast building and exploration of custom models. These projects might help particularly given the topic of this meeting.
Attending to the CTSP Meeting would be a great opportunity for me to share this ongoing work with the very active and growing CSDMS community as well as other international research communities. It would be very interesting to see how can we collaborate together to improve and integrate our respective tools.
I look forward to hearing from you.
Best wishes,
Benoit Bovy +
Deltas of big rivers are one of the most important fluvial landforms on earth. They were the cradle for ancient civilizations and are the rice basket of the world. Some of these large fertile deltas support extremely high population density and are in parts of the world with rapidly developing economies (e.g., the Ganges-Bramhaputra-Meghna Delta (GBMD)), which makes them more vulnerable to natural hazards. The most robust way to evaluate different factors that affect the dynamics of a delta is a realistic high-resolution physically-based numerical model, based upon an increased understanding of the processes at work. Currently the state of art is not at a point where morphological evolution of a delta and its complex physical-processes can be modeled in detail across morphological time-scales. Thus, my long-term research goal is to create a high-resolution modeling framework for deltas, that considers different processes like subsidence, ground-water flow, vegetation growth etc. One of the processes I am interested in for the model of the GBMD system is tectonic processes, which is underlined by the presence of the locked megathrust fault beneath the Indo-Burman mountain ranges, and the catastrophic large earthquake it may cause. Such a huge earthquake has the potential to avulse the rivers forming the GBMD, thus it is imperative for future hazard mitigation to understand how GBMD will react to river avulsions and resulting change in sediment-flux. In the past, analysis has been done to evaluate the effect of 1950 Assam earthquake on the morphological response of the river system, but the analysis was limited to change in sediment load in the system.
My background is in developing high-fidelity CFD models for complex environmental flows, and numerical models for predicting morphological evolution of fluvial-systems. Through this workshop, I hope to learn about the state of the art models for tectonic evolution, which will help me to include them in the models I develop in the future. This workshop will also introduce me to the community of scientists creating models for the evolution of the earth surface.
During the recent years, I have been working with Peter Molnar, Bob Anderson, Eric Kirby, Mike Oskin to understand the Cenozoic evolution of NE Tibetan Plateau. I used basin analysis, low-T themochronology, cosmogenic nuclides to study tectonics, structural geology and geomorphology, mainly focusing on the coupling of tectonic deformation and surface processes. I hope my attendance can help me broaden my research and bridge some potential collaboration between US and China. +
From this workshop, I expect to learn more about cutting-edge research and innovative ideas on coupling large scale landscape evolution modeling and geodynamic modeling. Currently, I am doing research on the surface manifests, particularly sedimentation, of isostasy or mantle flow in North America. There still remains many debates over the mechanisms of surface features such as the formation of the Western Interior Seaway, the uplift history of western US in general and the evolution of eastern US including the uplift of Appalachian Mountains. Hence, I aim to use coupled landscape evolution modeling to place additional constraints on lithospheric and deep mantle evolution underneath North America based on observations on surface processes. For future research, I also plan to utilize geodynamic modeling, either forward or inverse, to explore new possible mechanisms that led to the observed landscape evolution features. Of course, such method can also be applied onto other places. I believe this is a very special opportunity to expose myself to others conducting similar research and share ideas and experiences among attendees. In this workshop, I hope to learn from my peers in similar research areas and even find collaborators to push the frontier of the research on coupling landscape evolution and geodynamic modeling. Therefore, I really want to join this workshop, which is beneficial to me. +
How continental-scale rivers respond to tectonics, climate, and sea level is not well represented in morphodynamic models. Lowland rivers respond to influences more complicated than mountain rivers, and their large spatial scales present modelling challenges. Tectonic deformation and resistant deposits/bedrock especially affects low gradient rivers and their slope, sinuosity, along-stream patterns of sediment transport capacity, channel patterns, floodplain construction, and valley development. During glacial-marine transgressions vast volumes of sediment are deposited due to the infilling of lowland fluvial systems and shallow shelves, material that is removed during ensuing regressions.
Modelling key multi-directional processes controlling these rivers would illuminate system-scale morphodynamics, fluxes, and complexity in response to base level change, yet such problems are computationally formidable. Large environmental systems are characterized by strong process interdependency across domains, yet traditional supercomputers have slow nodal communications that stymies interconnectivity.
The newly developed Landscape-Linked Environmental Model (LLEM) utilizes massively parallel architectures (GPUs with >5000 cores and ~100x the interconnect bandwidth of CPU blades) to simulate multiple-direction flow, sediment transport, deposition, and incision for exceptionally large (30-80 million nodes per GPU) lowland dispersal systems covering large spatial and temporal scales. LLEM represents key fluvial processes such as bed and bar deposition, lateral and vertical erosion/incision, levee and floodplain construction, floodplain hydrology channel hydraulic geometry, dissection of weak sedimentary deposits during falling sea level, tectonic and glacial-isostatic flexure. LLEM also uses novel, ultra-fast Optane storage to reference a detailed 3D record of all stratigraphy (and associated biogeochemistry) that is created and destroyed. +
I acquire seismological data to image Earth's interior and its active deformation, while working closely with geodesists to measure surface deformation accompanying dynamic processes. My focus is on seismic and aseismic deformation in the creation of tectonic and orographic landscapes, and in understanding the surface processes modulating the dynamic and isostatic processes. My students work on seismological data constraining the kinematics of fault rupture leading to topography creation, and numerical models of the faulting and magmatic system responses. Our primary goal in attending the meeting is to consider dynamic and magmatic processes in the creation and modification of rift flank and orographic relief. +
I am Oluwaseun Idowu Fadugba, a third-year Ph.D. student at the Center for Earthquake Research and Information (CERI), University of Memphis. I am working on the effects of pre-existing structures on the seismicity of the Charlevoix Seismic Zone, southeastern Quebec, Canada. I wish to apply for the workshop on Coupling of Tectonic and Surface Processes (CTSP).
The Charlevoix seismic zone (CSZ) occurs along the ancient St. Lawrence rift zone in southeastern Quebec at the location of a major Devonian impact crater. The crater superimposed three major basement faults trending N35E and dipping at 70 degrees to the southeast. Many earthquakes are recorded each year in the CSZ and are concentrated within and beneath the impact crater. Some large-magnitude earthquakes associated with the rift faults occurred outside the crater. Using PyLith, an open-source finite-element code for simulations of crustal deformation, we set up a model for a 150 x 150 x 40 km crustal block. The model includes the three rift faults with friction coefficient in the ranges of 0.1 and 0.6 and cohesion between several MPa to 10s of MPa. We constrain the fault geometry using recent hypocenter relocation studies. In this study, we present a new set of numerical models that include more realistic relative spacings of the rift faults on stress distributions and correlate the observed stress distributions with the recent hypocenter relocations to better explain the seismicity. Our work provides an explanation to the change in the SHmax orientation inverted from earthquake focal mechanism compared to SHmax orientation determined from borehole breakout measurements. We also consider and discuss the effects of the high-velocity bodies imaged at mid-crustal depths in recent tomography study on the region's stress distribution.
I hope to be accepted for this workshop because it will give me the opportunity to contribute to the geodynamic community in the development of efficient numerical algorithms by asking questions relating to numerical models from experiences in my Ph.D. research workflow. I will also present the preliminary results of my research work. The wealth of knowledge of scientists and the helpful questions during and after the presentation will go a long way in my Ph.D. research. This will also help in shaping my research ideas and enhance collaborations with researchers and fellow students with a view to enhancing the impact of CIG and CSDMS communities.
I am PI/organizer of the Coupling Surface and Tectonic Processes workshop (25-27 April 2018, Boulder) +
I am a PhD student at the Geoscience-Environment lab in Toulouse. My work consists of modeling the interaction between erosion, silicate weathering and climate at the global scale and at the geological timescale. The aim is to explain climatic variations throughout the Earth History by changes in the erosion/weathering system (such as orogenies or mountain ranges decline). Such a modeling work requires a spatial discretization of continents, as well as upscaling of smaller-scale processes due to the coarse resolution (hundred of kilometers). In the future, I would like to explore further how weathering is affected by the horizontal advection of sediments, tectonic forcings and landscape evolution. The complexity of small-scale processes and computational costs are the main limitations of this investigation. Therefore, I wish to discuss the possibilities and barriers of upscaling from the catchment scale to the continental scale: what is the appropriate scale for each process, (tectonic forcings, evolution of topography, weathering, climate…). For instance, one key issue is how well hydrographic network should be represented (for sediment routing or calculation of drainage area), and how to upscale it. Another issue is how well constrained are the existing models and to what extent a combined model at these spatial and time scales would be relevant. This meeting is a very good opportunity to have a scientific discussion about those topics. +
I am a Research Fellow at the Department of Geology, Utah State University, specializing in numerical techniques for modeling lithospheric and upper mantle dynamics (https://ravi-vs-kanda.github.io). My research focuses on the use of laboratory based viscous creep and plastic rheologies to understand how a realistic lithosphere and crust modulate deformation over the region encompassing the uppermost mantle to the surface. Present-day surface topography, mantle tomography, along with long-term surface sedimentary and paleo-altitude records are key constraints on near-surface rheology, was well as in quantifying the relative importance of surface vs. mantle processes for surface topography.
For numerical modeling, I have been using SULEC (Buiter & Ellis 2012) – an Arbitrary Lagrangian-Eulerian visco-plastic code capable of modeling a true free surface of the Earth. I recently modified the 2D version of SULEC to incorporate spatially heterogeneous, material dependent, (1D) parameterizations of surface erosion and sedimentation (e.g., based on regional topographic slope, curvature, and/or nearest topographic peak). I tested the modified code with simulations of first-order topography across central Colorado Plateau (2D section, since 50 Ma). While preliminary results are promising, the extensions of my current 1D algorithms to 2D surface processes are numerically expensive and inefficient for practical use, specifically owing to the very different spatio-temporal scales of surface and mantle driven processes.
We recently got funded for a numerical study of the distribution of deformation and seismicity in the Intermountain Seismic Belt, using realistic rheologies – surface processes could be important in redistributing regional crustal stresses from deeper mantle sources there. I would like to learn more from the CIG-ASPECT community regarding their plans for surface processes. I want to attend the CTSP meeting in order to not only learn from leading experts regarding the latest advances in integrating surface process simulations into LTT models, but also to explore potential collaborations within such a broad, diverse group of researchers. As an early career scientist, I will greatly benefit from the experience of writing a White Paper exploring avenues to fund such future collaborations.
I am a first year faculty member who has long been interested in problems related to the coupling of surface and tectonic processes. I have a diverse background which I believe gives me an important perspective on this topic. Specifically, as a graduate student, I focused on field based structural geology and the tectonics of mountain ranges. I then did a four year postdoc working on various problems using landscape evolution models and separate projects using cosmogenic isotopes and developing tools for topographic analysis. With practical experience in both tectonics and surface processes, I am now uniquely suited to contribute to the broader community effort focused on studying the coupling of surface and tectonic processes. This workshop would be an invaluable opportunity for me to (1) get a sense of what others are working on, (2) identify problems to which my skills might be best applied, and (3) build collaborative relationships with potential new colleagues. +
I am a first-year doctoral student in sedimentology. As a sedimentologist, my previous experience is either about analyzing the large-scale basin development (subsidence history in foreland basins) or the smaller scale sediment transport processes (meandering river migration and avulsion). I preferred to use the sedimentary records in the filed and numerical modeling to approach these questions. Such background gradually makes me realize that smaller scale sediment transport processes might possibly affect the larger scale basin evolution sometimes. However, the connection between the two different scale (both spatially but and temporally) earth processes is rarely noticed or mentioned by previous studies. Therefore I choose to continue a doctoral project about it.
As a first-year Ph.D. student, I am still developing my research topic. Although it is not decided yet, it will be related to how sediment transport processes reflect or influence the evolution of continental rift systems. My hope is to approach this problem with both traditional stratigraphic analysis and numerical modeling. This short course, which is about the long-term tectonic processes coupling with surface processes, is tightly related to my research interest. It is an amazing opportunity for me to communicate with people who are specialists in both tectonics and surface process. Besides, I also want to know more about the techniques in numerical modeling and researches from tectonic aspect. In general, I strongly believe that this short course will inspire me and help me figure out the specific topic I want to pursue for my Ph.D project or even future career. +
I am a fluvial geomorphologist, and a postdoctoral researcher. My PhD focused on the coupling of tectonics and climate. Specifically I worked on the climate side, trying to understand how rainfall influences fluvial incision in mountainous bedrock rivers, and to develop simple, yet accurate and representative, techniques to describe that influence for use in landscape evolution models. We have had success in this project, and I am itching to learn how to apply our new theoretical tools in a new generation of landscape evolution models with dynamic tectonics and coupled dynamic climate. I am interested in taking an active part of defining the next steps for landscape evolution modelling. I can contribute my climate, hydrology and geomorphology background to the discussion, and I want to learn about the cutting edge in tectonic modelling. Further, as a postdoc, I am currently open to new projects, ideas and collaborations for the next stage of my career, and would benefit from the exposure to this workshop. +
I am a fourth-year PhD student in Geomorphology at CU Boulder. My research focuses on the evolution of hillslopes developed in layered sedimentary and igneous rocks, particularly when they occur in tilted formations (hogbacks). Every hillslope model I make uses an initial condition that assumes a certain tectonic history. For example, models of hogback evolution begin with a predetermined rock fracture structure and dip of tilted layers, and are driven by independently assigned boundary incision or rock uplift rates. While these tectonically-relevant processes control much of the behavior of the model, I have yet to implement them in a physically-based way. Additionally, this modelling approach fundamentally focuses solely on the influence of tectonics on hillslope evolution without considering interactions between the two. The Coupling of Tectonic and Surface Processes workshop would be an ideal opportunity for me to connect with other researchers in order to better understand the feedbacks between hillslope evolution and tectonic drivers at the landscape scale. If given the opportunity to attend, I plan to present a poster about my collaborative work with Charlie Shobe regarding the role of large blocks of rock in a 2-D coupled hillslope and fluvial model in Landlab. This project is relevant to the workshop because it illustrates how feedbacks between hillslopes and can modulate the propagation and overall effects of tectonically-induced base level change on landscape evolution. +
I am a geologist with the Seismology, Geomorphology, and Geophysics group at Bureau of Reclamation. Our group performs seismic hazard evaluations for federal dams, which typically involves a fault study at each dam site. While traditionally we have focused our investigations on fault scarps, we are working on expanding our investigations to a wide range of landscape response to faulting. This development is significant because our research is limited by the location of the dam, and we often work with subtle tectonic expression at less than ideal sites. We would like to incorporate more computational modeling into our site analyses, which have traditionally been based on field work, imagery analysis, and trenching. We would also like to take advantage of the growing availability of lidar datasets, in addition to the lidar datasets funded by our agency, from an analytical perspective. We believe that becoming more familiar with current numerical modeling techniques will help us to better take advantage of accessible data as well as providing us with additional tools to apply in our seismic hazard assessments. My personal research background (I completed my MS in August 2017) is in the tectonic deformation of the Lake Bonneville shorelines by the Wasatch Fault Zone. The majority of my experience in numerical analysis is developing algorithms to take measurements from present day elevation data. One problem in my research was the uncertainty in measurement variability – which ultimately was a reflection of our uncertainty in landscape response to tectonics versus erosional processes. This issue becomes important to my work at BOR as we try to integrate some of the numerical tools I have developed in our fault investigations. As an aside - I live in Denver and will not need lodging or transportation costs covered. Thank you for your consideration. +
I am a metamorphic petrologist and geochronologist. My research is focused on deciphering the pressure-temperature-deformation-time history followed by high-grade rocks. I am particularly interested in the influence of climate-related processes (e.g., mass flux due to fluvial and glacial systems) on the exhumation and cooling history of these high-grade metamorphic rocks. I am currently writing a proposal with two PIs to investigate these processes within the highly active New Zealand Southern Alps. The CTSP theme of this meeting directly relates to the questions that we are proposing to address within the proposal. I am keen to hear the latest in this research field and share some perspectives of research that is currently being done on the deeper tectonic levels of orogenic systems (i.e., the mid- to lower-crust and within ultrahigh-pressure terranes). +
I am a postdoc at Stockholm U., previously a postdoc at U. Tuebingen (Germany), PhD from U. Washington in 2014. See more about me at karllang.info
I would like to attend because I have been working on projects concerning the coupling of Tectonic and Surface Processes since 2008 but have never actually attended a workshop dedicated to this theme - its thrilling! I have a lot to share on this topic, but still a lot to learn from others. My background is in low-temperature thermochronology and geochronology, particularly applied in a detrital context. I have experience with thermo-kinematic modeling (namely PECUBE and PECUBE-D) used to predict thermochronometric cooling ages.
My PhD and Postdoc work has been focused on using detrital cooling ages to reconstruct paleo-exhumation rates from foreland basin sequences - actually testing modeling of landscape evolution over 10^6 yr timescales. I have focused specifically on testing the "Tectonic Aneurysm" models of the eastern Himalaya (PhD) as well as the influence of a rainshadow on the evolution of the New Zealand Southern Alps (Postdoc).
I am also eager to work on older orogenic records for which there is no modern context and modeling is key to interpreting paleo-exhumation rates (e.g. Caledonian orogeny). To this end, I am looking to learn about new modeling approaches that can integrate tracking of particle thermal histories for T/t reconstruction of cooling age calculations.
I am happy to present parts of my PhD, Postdoc work or both! +
I am a second year Masters student in fluvial geomorphology. While my current research is not directly related to tectonics or simulations, I will be starting a Ph.D. program at UBC next year focused on landscape evolution from a fluvial perspective and will be using/developing numerical models. Additionally, I am already familiar with concepts in tectonic geomorphology and numerical modeling as I have a background in geology and computer science (BS and BA, respectively, UC Santa Cruz 2015). I want to attend this conference to explore the current state of research, meet researchers in the field, and start focusing ideas for my upcoming Ph.D. work. +
I am a second-year Ph.D. student working with Dr. Juliet Crider on developing a project on fault scarp degradation in jointed bedrock. I have completed fieldwork in Iceland and am compiling my results on the morphologies and other characteristics of the scarps. I hope to one day integrate these results into a numerical model of fault scarp degradation in jointed basalt. I believe that this workshop would be an excellent opportunity to deepen my knowledge of numerical techniques and how they relate to my specific coupled tectonic/surface processes project. +
I am a second-year PhD student at Yale University, studying tectonics, structural geology and geomorphology. My dissertation research, advised by Mark Brandon, focuses on the deformation, uplift and erosion of Santa Lucia and the Coastal Ranges in California. Attending this workshop on Coupling of Tectonic and Surface Processes (CTSP) will allow me to be introduced to new knowledge and develop new skills in my field. It will also provide me an opportunity to meet both the CIG and CSDMS communities, and to develop new collaborations with colleagues that are also interested in answering broad tectonic questions that relate to surface processes using numerical methods.
Understanding tectonic processes and their relationship with surface processes and climate has always been a passion of mine. My M.Sc. research at The Hebrew University of Jerusalem coupled tectonic uplift with sea-level changes based on uplifted fossil reef terraces. Although I had no prior experience with numerical methods prior to my current research project, I do have general programming knowledge in C, C++, and Matlab. Currently I am working with ‘Gale’ to build a geo-dynamic model for the uplift of Santa Lucia. For the next step I would like to couple the tectonic uplift with erosion using a PeCube inverse approach and thermochronologic data.
I am always looking for opportunities to advance my knowledge and skills and to learn about current topics of tectonics and surface processes. Even so, I was surprised to come across a workshop that seems to fit so well with my interests as this Coupling of Tectonic and Surface Processes. I feel that advancing my knowledge in current research questions and numerical techniques will be most beneficial as I am a newcomer to the field. Thank you in advance for your consideration of my application.
Sincerely,
Neta +
I am a tectonic geomorphologist interested in studying interactions between Earth surface processes, tectonics, and climate. Most of my research projects integrate field observations, geochronology, data analysis and numerical modeling to test specific hypotheses. I am interested in attending the Coupling of Tectonic and Surface Processes workshop for several reasons. First, as an early career scientist (I will be beginning as an Assistant Professor at CSU in January of 2018), I am excited to interact with other like-minded researchers and hope to foster new collaborations through participation in the workshop. Second, I am interested in learning what software is available through the CIG and CSDMS communities that I might be unaware of which might benefit my current research. Finally, I would like to talk with other scientists about ideas that I have to integrate some of my existing numerical models into the new LandLab landscape evolution model and gauge community interest in building these modules. +
I am a third-year PhD student. My PhD project focuses on investigating how deep Earth processes (e.g. mantle convection, mantle upwelling, subduction) influence continental-scale landscape and drainage evolution, and the associated formation of stratigraphic architecture on continental margins through geological time, using landscape evolution modelling. Specifically, I worked on how dynamic topography contributes to drainage reorganizations and how it influences the development of stratigraphic sequences on passive continental margins. I obtained rich experience in the numerical modelling of the coupling between tectonic and surface processes. However, I have not worked on examples in the real world. The aims to attend this workshop are to: 1/ discuss about the numerical tectonics of the coupling modeling; 2/ obtain deeper understanding of the coupling between tectonic and surface processes; 3/ get some insights on applying the numerical modeling to the real world. I hope I could contribute by sharing my experience and ideas. +
I am currently a Harry H. Hess Fellow at the Department of Geosciences at Princeton University. I would be extremely interested in attending this workshop for that it would allow me to connect with a diverse group of potential future collaborators, with a unique shared interest of coupling of Earth surface processes to tectonic forcing.
I have previously studied a diverse range of geomorphological and geological phenomena using experimental, numerical and theoretical techniques combined with field observations. In my research, I look for universal laws of transport, erosion, and deformation applicable to Earth surface and subsurface processes, and seek a fundamental understanding of geomorphological an geological processes, from asperity and grain rearrangements to geological (fault and basin lengthscale, up to million year timescale) spatiotemporal scales, with knowledge of the behavior of disordered amorphous Earth materials.
In the past year, I worked on developing a unifying mechanistic framework for sediment transport and landscape evolution from slow earthflows to fast landslides, across the scales and environments. In continuation of this work, I intend to next focus on tectonically active regions, taking into account tectonic evolution, deformation of continental crust and uplift rates and tectonic patterns
for future landscape evolution models. This step would require i) developing a rigorous physical understanding of how these processes (landsliding, mass wasting and tectonic forcings including uplift) interact and result in recurrence time and size distributions of earth surface slips; ii) finding and testing the functional form(s) of the transition to landsliding in steep hillslopes, and physics of healing that is perhaps a controlling factor of landslide recurrence times.
I will use the great opportunity of this workshop to discuss and learn about these ideas and hopefully find potential collaborators with whom I can can work on them.
I am currently a postdoc research fellow at the Department of Geosciences at the University of Arizona. I have wide interests in geomorphological and tectonic research using numerical modeling combined with field observations. It will be a great opportunity of this workshop to discuss and share my research and idea with my colleagues and potential collaborators.
In my present and previous research, I mainly worked on developing a couple of model frameworks about sediment transport and landscape evolution from the mountainous environment to coastal environment. One of my previous research is about hazard-related surface processes in subduction zone like earthquakes and tsunamis. We are trying to develop a physical process-based model framework to simulate the landscape evolution during tsunami and earthquakes. Based on tsunami deposit in the geological record, we can analyze the frequency of earthquakes or tsunamis in a given period and then reconstruct the coastal landscape evolution history. My present research is about post-fire debris flows and landslides in Southern California area. Sediment flux in the channels often increases by more than an order of magnitude after fires. Rainstorms following fires can lead to channel infilling and debris flows that cause loss of life and property. Since the post-fire debris flows significantly change the local landscape, now we are trying to account debris flow into our landscape evolution models to predict landform response to climate and tectonics.
In this workshop, I would like to present and get feedback about our coastal landscape evolution model and debris flow model. I also want to expand my ideas and ways for incorporating our debris flow and landslide model with tectonic models. It will be a great chance to discuss with tectonics modelers who are interested in integrating tectonics into surface processes model to share ideas or write a proposal together. +
I am currently working on implementing fully coupled models of tectono-magmatic extension and surface processes to understand the feedbacks between deformation and topography growth. This workshop would allow me to present novel results and learn about state of the art techniques from fellow modelers. +
I am deeply inspired and eager to have an opportunity to learn during the scientific program “Coupling of Tectonic and Surface Processes (CTSP)” going to be organized by the prestigious institution, University of Colorado (Boulder), USA. As a fresh Ph.D. graduate, I am currently looking for opportunities to pursue my career objectives. I plan to be a researcher in geoscience. My areas of interests are, Seismology, Seismic Tomography, Tectonics, Geodynamics and Seismotectonics etc. I believe that this workshop will enrich me in new ideas and give a great impact on my career plan. The topic and theme of this workshop seems promising and fruitful for me in terms of the learning opportunities, training facilities and intelligent and knowledgeable technical lectures and discussions by the eminent and globally renowned scientists and researchers. The energetic, strong technical and scientific environment with an international exposure, which aims and ensures the crosscutting scientific skills and experiences to the researchers, motivate me. This program is an unmissable opportunity for me to explore variety of different aspects of research, share best practices and findings and find out about the latest and cross-cutting research in my intended research field. The interactive technical sessions during the program would lead me to gain invaluable knowledge and research skills. I would also have the golden opportunity to interact and share my knowledge and skills with the renowned researchers and international delegates and may get an opportunity to collaborate and work with them in future. I believe that close interactions with the cutting edge researchers, early career geoscientists will be a great benefit for my future career as a geophysicist or seismologist who can contribute and give constructive feedback for my intended research field. I also plan to expand my networks within geoscience community which will be useful for future collaboration.
I am doing my PhD on the interactions between tectonics, climate, and erosion at the Institute of Earth Surface Dynamics (University of Lausanne, Switzerland) under the supervision of Frédéric Herman. In my project, I am developing an inverse model to quantify the spatial and temporal exhumation history of the Chilean Andes, using own and literature low-T thermochronological data as model inputs. The constrained exhumation rates are compared to the structural and climatic evolution of the orogen to get insights into the response of erosion to climatic variability and tectonic changes. As a second project, I am investigating the influence of glacial erosion on exhumation at the latitude of Santiago, where the geology is well constrained and remained relatively stable since the last 23 Ma. I use a thermo-kinematic model, modified from Riesner (2017, PhD thesis), to simulate thermochronological ages using geologically constrained fault kinematics and observed shortening rates.
Modelling of thermochronometric data requires a good understanding of the surface evolution, since relief formation modifies the subsurface thermal field. Attending to your workshop would enable me to improve my competences in landscape evolution modelling. In turn, I could contribute to the understanding of (inverse) numerical models to constrain exhumation using low-T thermochronological data. +
I am going to work on the coupling of surface processes using Badlands (Basin and Landscape Dynamics) and tectonic processes using DynEarthSol (Dynamic Earth Solver). This is an extension to my current project involving the stress modeling of the effects of upper mantle structures on the seismicity of the New Madrid Seismic Zone. I ignored the effects of the ongoing surface processes in this area (e.g. erosion of Mississippi river) which may further affect the seismicity and want to investigate the complete coupled system in this project.
This workshop will give me useful insights into the current state of available codes and guide me into the numerical limitations for my project. If possible, I would also like to exchange my ideas with the developers of the codes I am planning to couple to get their feedback. +
I am interested in climate-erosion-tectonic interactions and feedbacks and, therefore, in what the CSDMS community uses to asses forces and drivers at the various temporal and spatial scales. Tectonics can be measured at different temporal and spatial scales as well, so it is important to specify which aspects of tectonics are being referred to in an explanation of rates of surficial change, such as erosion. I think that we need to determine scaling parameters in order to be able to say how LTT plays out temporally in affecting rates of surface processes. This may take more than modeling, but modeling can be used to generate hypotheses about where and how to test for these through physical measurements in the field. I have being doing my own modeling by writing my own MATLAB code and interested in the community developments and how I might incorporate them. I am also early career and trying to become more engaged with the modeling community for the topic. +
I am interested in computational lithosphere dynamics and coupling of tectonic with surface processes models. We had a few related publications on this during the last few years. +
I am interested in participating in this workshop, because I am working with a coupled tectonics and surface processes model (TISC) for one of my postdoctoral research projects at New Mexico Tech. Eventually, we aim to utilize this code to model continental extension, erosion, and sedimentation in the western U.S. As part of this project, I have been working to modify the source code to include additional sedimentation processes that are not yet accounted for and to improve various aspects of fault movement in the model as well. Because my research background is in a different field (seismology and tectonics), I think that I would benefit greatly from discussions at the workshop, particularly given the expertise of the organizers and the participants that have already signed up. I would also be very interested to get some feedback on the work that I have been doing with this project. +
I am interested in the long-term evolution of the solid Earth. One research approach I take is to link surface processes to deep Earth dynamics through quantitative landscape evolution simulation. This CSDMS workshop provides valuable resources for furthering this research. +
I am interested primarily in the interaction between tectonic processes and river channel evolution. My PhD thesis work focuses on the erosion of rivers that experience the delivery of large blocks of rock from adjacent hillslopes (Shobe et al., 2016, GRL; Shobe et al., submitted, JGR-ES). Such landscapes require two conditions to form, both of which are controlled by tectonics. First, the underlying bedrock must be pervasively fractured. Second, the channel must be eroding rapidly enough to steepen hillslopes and allow block delivery. Tectonic stresses control fracturing of rock, and tectonic uplift relative to baselevel sets long-term rates of river erosion. As such, tectonic processes govern the two boundary conditions for block-influenced river channels. My numerical models of channel evolution do not include physically-based descriptions of these processes, but I am interested in learning how to potentially implement tectonic forcings into my models. Attending the CTSP workshop would allow me to learn the newest approaches to modeling tectonic processes.
Attending the workshop would allow me to progress on other work as well. I have recently developed a model for the long-term evolution of bedrock-alluvial rivers (Shobe et al., in press, GMD), and am looking for ways to use this model to test two-way feedbacks between fluvial erosion and tectonics (e.g., the connections between fluvial sediment transport, lithospheric flexure, and landscape evolution). Meeting other attendees with far more expertise in these areas than I have will help me focus my efforts on the most salient problems. +
I am leading a NSF-sponsored project in which we study drainage development in a continental rift. Because in our study area the tectonic history is well known, we are using a 3D kinetic tectonic model (in which we can prescribe fault slip), and have coupled this with a surface processes model that includes erosion, transport, and deposition.
Our modeling approach is thus different from other groups that often use dynamic models for the tectonic development of the study area. Two members of my group are applying for this conference as well: Michael Berry, and Erica Emry.
I just finished a project in which we report on a rift-wide Mio-Pliocene unconformity in the Rio Grande rift. We have been able to directly relate this lacuna to mantle convection. +
I am one of the main developers and maintainers of the open source geodynamics software ASPECT, which is also used in the tectonics community. I would like to participate because surface evolution is a topic of interest for a number of our users, and I would like to help with designing an interface that allows ASPECT to be coupled to surface evolution codes. I also think I can contribute to discussions about the requirements for such an interface from the tectonics point of view. +
I am one of the main developers of the ASPECT mantle convection code that gathered increasing interest in the tectonic's community. I would like to participate to stay in the loop, learn from this community, and provide guidance and help for implementation. +
I am one of the maintainers of the ASPECT modelling code, and was already responsible for the interfaces between ASPECT and codes such as GPlates, Perplex, and Hefesto. Since surface evolution is a topic of interest for many of our users, I would like to participate in discussing and designing the necessary software interfaces. Additionally, I think I can contribute to the discussion about suitable approaches for coupling, and the technical problems that are likely encountered. +
I am very interested in attending the CSDMS workshop on Coupling of Tectonic and Surface Processes (CTSP) at CU Boulder. I a fluvial geomorphologist and a PhD candidate at Colorado State University, advised by Dr. Ellen Wohl. My PhD research focuses on the geomorphic controls on floodplain carbon storage in sediments and downed large wood and floodplain dynamics in the Yukon River Basin in interior Alaska. I investigate the geomorphic controls on carbon dynamics in river corridors across spatial scales. My research interests are broad, however, and I am interested in expanding my knowledge of numerical techniques to investigate surface processes and the linkages between tectonics, landscape denudation, and sediment yields. I would also like to create connections and interact with researchers with diverse interests in earth surface processes and tectonic processes. Although I currently am not working on projects directly related to the topic of the workshop, I would like to move towards incorporating long term tectonic processes into my work. In addition, I am interested in geomorphic research that incorporates multiple temporal and spatial scales. +
I am very interested in participating in this Coupling of Tectonic and Surface Processes workshop and learn about numerical techniques. I am a post-doc in the University of Cincinnati that researches active tectonic and neotectonics and surface processes, currently applying geochronology techniques (TCN and OSL), processing my own samples in the Quaternary Geochronology Laboratories in the UC. In this sense, one of the lines of research that I have been following is investigating long term processes, such as long-term fault slip rates, erosion rates for basins or long term crustal deformation such as investigating Pleistocene uplift rates and their relationship with sea-level oscillations and GIA. I have conducted research for my PhD in Portugal (where I am native from) and presently I am conducting research on temporal and spatial variation in fault slip rates across the Cajon Pass area, San Andreas Fault (Banning strand), Eastern California shear zone (Calico and Camp Rock faults), along several faults in the Walker Lane, Pleistocene landscape development across the Eastern Caucasus Mountains, where I investigate a section of an intracontinental mountain belt through the quantification of catchment-wide erosion rates and applying several tools for morphometric analysis. I am extending my previous studies on the regional uplift analysis for SW Portugal through the morph-analysis of a wider area applying TanDEM-X (high precision digital elevation) and also including basin erosion rates. I have learned greatly from my previous experiences participating in workshops while a graduate student and I believe that interacting with other researchers will also benefit my post-doc research and my academic career. Sharing different experiences about different tectonic and climate settings which ultimately condition surface processes at different rates is a great way to find common and news paths of research as well as getting the chance to establish new collaborations.
I am very interested in the response of the local rivers to the creation of the Rift Valley during the Miocene. While some of the rivers look "normal" with standard drainage patterns, some exhibit peculiar meanders and channel features that suggest they were operating during a period there were two competing base levels. Relatively little work was done on the subject and I hope the workshop will give me some insights into tectonics and tools of how to couple uplift and subsidence with river processes. +
I am writing to apply to attend the CSDMS annual meeting in 2018. I am a PhD candidate in geology from Oklahoma State University. I learned about CSDMS annual meeting and its workshop when I talked with Dr. Arthur Olive in GeoPrisms early this year. I notice the conference theme, Coupling of Tectonic and Surface Process, is especially relevant to my professional expertise, and therefore I would highly appreciate being given an opportunity to attend this event gathering feedback and suggestions.
My PhD research proposes to examine the geomorphic response to tectonic uplift in the East African Rift system, especially focusing on the distribution and rate of uplift in Ethiopian Plateau using numerical models and morpho-tectonic analysis. The results of my work will provide insights into the identification of potential source areas, transportation paths, and sediment accumulation rates in a tectonic rift setting. Therefore, this workshop provides me a great opportunity for me to gain feedback and push my work forward. I will also bring back to my research group at Oklahoma State University, this newly gained knowledge, and numerical models. My attendance will also benefit our research group at large.
Also, my work will enhance diversity in the field of surface dynamics modeling. For example, I am building up a knickpoint celerity model to reconstruct an end-member age framework in the environment of Landlab. These work will provide some insight on the variation of channel incision and uplift in both spatial and temporal scale. Therefore, it can contribute to the modeling of surface processes from the perspective of tectonic geomorphology and provide examples at continental rift settings.
As I have outlined, CSDMS will be an excellent platform to establish myself and exchange ideas. I am looking forward to attending the CSDMS conference, and I kindly request that the committee looks favorably on my application. Please let me know if you need further information.
I am writing to express my interest and motivation in attending the Coupling of Tectonic and Surface Processes Workshop in Boulder, Colorado. I am a postdoctoral researcher at the Institute of Geophysics and Planetary Physics (IGPP), Scripps Institution of Oceanography, UCSD, and I specialize in 2D and 3D forward numerical simulations of convergent margins at lithospheric scale.
During my PhD, I have been using numerical models to better understand the evolution of continental collisions, how mountain belts are formed and why the Himalaya-Tibet belt is so strikingly different from all other mountain belts. For my postdoctoral research at IGPP, I employ numerical models to address questions regarding the dynamics and evolution of subduction and surface uplift in the context of South American tectonics.
In my work so far, I have strongly focused on analyzing the evolution of topography at convergent margins. Topography represents the dynamic adjustment between tectonic forces and surface processes. However, how do surface processes link to subduction is not clear. Currently, I am interested in investigating how sediment fluxes influence subduction dynamics or the height of mountain ranges above subduction zones. My goal is to understand the factors that cause convergent margins to either accrete continental material delivered by the subducting plate or, alternatively, to subduct the trench sediment pile and even erode the basement of the upper plate.
The main reason why I am keen on participating in the CTSP workshop is that I am highly interested in expanding my knowledge and skills necessary for studying the dynamics and evolution of convergent margins in an interdisciplinary perspective of coupling tectonics and surface processes. I believe that the CTSP workshop is one of the best opportunities to stay up-to-date with latest research in this regard. +
