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. +
I have a longstanding interest in understanding the feedbacks between climate, erosion, and tectonics and am currently working on the impact of glaciation on the dynamics of critical wedge topography. I also would like to become better connected to the CSDMS community. +
I have been engaged in numerical modeling of continental extension throughout my career. I am interested in expanding on that work to consider feedbacks between tectonic processes and surface processes in extensional systems, particularly as regards uplift, exhumation, and formation and filling of sedimentary basins. The workshop is timely for me, as recent growth in my department has added strengths in quantitative geomorphology and surface processes that create new opportunities for research and graduate teaching at CSU. Arrival of these new faculty creates new opportunities for collaborative research and graduate teaching. I hope to use what I learn from this workshop to establish a foundation for these future collaborations. My goals in attending the workshop are to develop a current understanding of i) the physical and numerical methods used to address surface processes, ii) how such processes can be integrated into numerical models of continental extension, and iii) the outstanding issues concerning coupling between tectonic and surface process that will likely focus research in the next few years. +
I have been working on coupling the numerical models of long term tectonics (LTM) with short term surface processes. I have used SNAC (LTM code) to run the long term simulations and then used CHILD ( Landscape evolution code ) to model the surface processes associated with it. I remained involved in the development of coupling these two codes under Basic Model Interface (BMI). I also worked on Fastscape (Landscape evolution code) to run simulations for landscape evolution.
Our main focus in the coupling is to model the dynamical topography resulting from the mantle flow at a very large spatial scale over tens of millions of years. Modeling topography from the interaction of the coupled tectonics with surface processes helps us better understand the interaction between these systems at different spatial and temporal scales. Modeling has proved to be helpful in understanding the behavior of large scale systems specially when they are coupled together and the interaction continues over the scale of thousands of years. I ran the initial models successfully and got some initial results ( thanks to Dr. Gregory E Tucker for replying to my emails and helping me understand the finer details of CHILD code). I still believe that when it comes to interpret/understand basic results from model simulations, I lack the skills to do that. I also feel a strong need to be exposed to more experts in this field to learn how the coupled interaction of different processes works and how we can better construct the history of landscape evolution. Reading more scientific publications definitely helps but as a early carrier research student, I believe that joining a workshop like this will be a great initiative to learn the fundamental aspects of coupling of short term-long term processes of earth. I also believe that this workshop will help me lead my work to new possible scientific directions. +
I have been working on this problem (CTSP) my entire career. My work in this arena has included a combination of field work, analytical/theoretical efforts, and landscape evolution modeling. I am particularly interested in the conundrum that although all models (physical, simple analytical, complex coupled numerical) indicate there should be strong coupling between tectonic and surface processes, this coupling has proved hard to demonstrate in the field. There is plenty of evidence consistent with expectations, but a dearth of compelling evidence that it must be so. If theory and models were telling us there should be no coupling, there is no field data that would have geoscientists arguing that the models have to be wrong.
Also my recent students and I have some - we think important - new constraints (data and theory) on the link between climate and erosional efficiency that I would like to share (a healthy fraction remains unpublished to date).
I would be happy to prepare a poster, but also willing to leave the poster space to younger participants. I'll click yes below to indicate willingness to contribute as called upon. +
I have great interest to participate in CTSP: Coupling of Tectonic and Surface Processes,going to be held at SEEC building on east campus
Boulder Colorado, United States 25 - 27 April 2018. I have wish for invited talk on "ANALYSES OF STRESS PATTERNS AND OCCURRENCE OF QUATERNARY THRUSTING IN HIMALAYAS" for the oral presentation. I will appreciate for the full financial support in the form of round trip travel, boarding-loading and living expenses. Frankly speaking my participation only depends on your full financial support and I will not get any financial support from our institute for the conference. I am presenting author form the developing countries. If possible consider me invited speaker. I will try to use cheapest Airfare and accommodation depending upon your convenience.
This conference is very beneficial for me to enhance my professional development in the field of research and teaching to learn the experiences of the learned leading scientists and professional gathered there. This visit would also give me an opportunity to search the possibility for the future research collaboration with the interested scientific community.
Therefore, I request to you and LOC for the full conference support( Travel support must). I take this opportunity to wish you all CSDMS community a very happy, healthy and disaster free New Year 2018 and beyond and wish the conference great success.
With regards.

I have spent a significant fraction of my research time in the past couple of years working on algorithms for efficient modelling of the landscape evolution / tectonic coupling problem for massively parallel environments and would like to share my experiences / learn what I really should have been doing all along. +
I have two broad research focuses that fit into the theme of coupling tectonics and surface processes. First, I am working to link lithologic characteristics to bedrock river morphology, sediment dynamics, and riparian vegetation. This project seeks to understand how bedrock characteristics like fracture geometry (a reflection of the tectonically influenced stress regime) influence the morphology of bedrock rivers. In turn, I am attempting to understand how morphology controls factors such as sediment retention and resulting vegetation growth in valley bottoms, which can have strong feedbacks on weathering and therefore erodibility. At the CTSP workshop, I would like to discuss how to connect the long-term feedbacks between surface processes and tectonics, namely how tectonically-influenced fracture geometry can influence bedrock river erodibility on the scale of mountain ranges over long time periods.
I also have an ongoing research theme focusing on carbon storage in mountain river valley bottoms in the context of climate change. This project compares 4 mountain river basins across the western U.S. to model how differences in climate (influencing hydrologic regime and primary productivity) and uplift (influencing valley morphology and erosion rate) relate to differences in carbon storage magnitude. This project has implications regarding the feedbacks between climate and mountain building. If climate and tectonics regulate surface processes in a way that alters the magnitude of the land carbon sink, that may act as a feedback regulating climate. I would like the opportunity to discuss how to integrate this kind of biogeomorphic research with numerical modeling to better understand the feedbacks between tectonics, landscape evolution, and climate. I would like to contribute to the broader discussion of applying our understanding of surface processes to improve numerical modeling of landscape evolution over large spatial and temporal scales.
I hope to attend this workshop to expand my understanding of tectonic and surface processes coupling, establish new collaborations, and share my research experience. I am a post-doc, I have extensive experience with geospatial computation tools, and I am a developer of the two-dimensional modeling framework, Landlab. My research is centered on the earth surface processes that link tectonics, climate, and life. I envision that the presentations at this workshop will provide a breadth of worldwide research within my interests, and present as well as reinforce the challenges that I will face in my early career.
I look forward to the opportunity to contribute to discussions and a white paper that describe how our communities can conquer research challenges and needs. I will apply observations from recent literature, workshops and meetings. For example, the challenges associated with bridging the great timescales in which earth processes operate was repeatedly mentioned at the July 2017 Feedbacks among Climate, Tectonics, and Erosion (FACET) meeting. I believe the LTT and surface processes communities can make a strong case for the potential of numerical models to address this challenge especially with the resources and capabilities of CIG and CSDMS.
I will contribute to this workshop my recent research. This includes my exploration of how landscapes and species co-evolve using a landscape evolution and a species evolution models that I coupled. Simulated tectonic processes drive increases of species diversity. I envision that this research is yet another example of the relevance of our research to highlight to outside communities. At this workshop and elsewhere I seek new collaborations to develop proposals that build on current research directions and establish new ones. +
I implement adaptive time stepping and rate (and state) friction into long term tectonic (LTT) geodynamics code. Therefore, I can study Tectonic and Surface Processes across time scales. My research aligns well with this workshop. I would like to exchange ideas with other attendees. +
I love surface processes, tectonics and models!!! Plus, I'm so interested I'm on the planning committee! +
