I specialized in the development and use of numerical methods to study the complex interactions between surface processes, climat and tectonics. I believe I can contribute to the very interesting topic go this workshop and learn from other participants about ongoing issues on the subject, both from a fundamental and technical point of view. I have asked one of my collaborators, Benoit Bovy, to apply as well. +
I study paleo and modern erosion rates in mountain ranges by measuring and analyzing the cosmogenic radionuclide concentrations in sedimentary rocks and alluvium, respectively. I am particularly interested in questions such as: at which point does the tectonic perturbation to base level overshadow the influence of climate in driving surface processes? Attending the Coupling of Tectonic and Surface Processes workshop will allow me to apply numerical modeling to evaluate which scenarios more likely explain the observations and data that I obtain in the field. Moreover, it will be a valuable opportunity to not only deepen my understanding of the state of the art landscape evolution modeling but also network with colleagues in the field to hopefully spur new collaborations. +
I want to attend this meeting to help define the problems our current models have and what we need to overcome them. I hope that I can contribute by helping us move towards solving them. I think a good way of understanding the next steps in how surface processes interact with long term tectonic processes is to catalog the current capabilities and limitations of our models. Some questions that I would like to ask and help answer are: What are our current numerical landscape evolution models good at, and how can we tell? What results can our landscape and tectonic models not reproduce? What are the missing processes that our landscape evolution models need to reproduce these results? What are the numerical and computational obstacles stopping us from incorporating these processes? From my adviser, Gary Parker, I have learned a great deal about reduced complexity modeling, and I know that adding extra complexity to a model adds extra complexity to the numerical and computational aspects of the code as well as complexity to the interpretation of the results. A problem I am currently working on involves understanding the feedbacks and interactions between landslides and landscape evolution. Landslides are important to landscape evolution because they can provide sediment that incises the beds of rivers by acting as an abrasive material. To study these interactions, I need to resolve how sediment moves within the landscape by coupling alluvial morphodynamics with a landscape evolution model. Currently, this incorporation into my code requires the time step in my model to be much smaller than what long-term landscape evolution and tectonic models normally use. I want to help develop a way to couple these spatially small and temporally short alluvial processes to large-scale and long-term landform processes in an efficient manner. This meeting would be a good opportunity to find others whom are interested in working on this problem or want to collaborate on other new ideas.
I wish to attend the workshop on Coupling of Tectonic and Surface Processes (CTSP) because of the strong relevance to my research. The workshop is very well timed as I am beginning the second year of my PhD research.
My research involves multi-scale investigation of sediment dynamics and channel morphologies of coarse-bedded rivers in New Zealand’s Wairarapa region (southern North Island). I have used high-resolution topographic data sets (e.g. LiDAR) to identify tectonic forcings on rivers at multiple spatial scales and am in the process of developing a hierarchical typology. This typology will reflect both fluvial and topographic signatures at multiple spatial scales with implications for follow-on work reflecting multiple temporal scales. I have also used a qualitative integration morphotectonics with fluvial hazards to provide a multi-hazard foundation to prioritizing field site selection for the high-resolution (Structure from Motion) component of my study.
I am specifically interested in the CTSP workshop to increase my knowledge of and gain proficiency in state-of-the-art numerical techniques. My primary aim is to increase objectivity in the previously mentioned elements of my work. I am happy to forward copies of either the poster and oral presentations I’ve recently given at the Geoscience Society of New Zealand (GSNZ) and International Society for River Science (ISRS) conferences in support for my application. I greatly appreciate this opportunity and hope your review of my application is favourable. +
I work on landscape evolution modeling over long time scales. I believe that tectonic/geodynamic models and surface models, until recently, have not been properly coupled: teconic/geodynamic models are used to drive uplift in surface models, but in many cases the surface models have no feedback on the teconics processes. Recent modeling work has been done to this effect but there is a high computational cost. I am interested in learning about these recent state of the art models, as well as reduced complexity models which may be sufficient to simulate tectonic processes and can be more efficiently coupled to landscape evolution models. +
I would be attending this workshop as somebody who uses landscape evolution modeling on a daily basis from solving the simplest form of an advective-diffusion equation to pushing hard to integrate mechanics-based approaches from grain-scale and event-scale frameworks into landscape evolution modeling. I would like to attend this workshop to: (1) share and get feedback on new ideas I have regarding the means by which we can use drainage basin geometry and changes in basin geometry to map long-wavelength, low-magnitude surface uplift of the type expected from dynamic topography; (2) share and get feedback on ideas I have for using characteristics of the upper reaches of the network, those primarily traversed by debris flows, as a high-resolution metric of surface uplift; (3) share and get feedback on ideas for bringing “real” mechanics into landscape evolution modeling from grain-scale and event-scale frameworks; (4) expand my ideas and toolkit for ways of incorporating tectonics into landscape evolution models (I know there is more than uniform U); (5) become better integrated with the tectonics modelers and people interested in integrating tectonics into Earth surface processes models such that I could write competitive collaborative proposals. +
I would like to attend as part of my duties as program officer at NSF. I am the managing program officer for the award that funds this workshop so, naturally, I am very interested in the results of the workshop. +
I would like to attend the CTSP course because I am strongly interested in the meetings' main subject. As an Earth Sciences PhD candidate, carrying out research at the Southern Central Andean western slope, I have strongly understood and considered the key aspect of erosive processes upon structural development of orogens (e.g., [1]).
I am currently developing analogue models applied to the Andean range, regarding basin inversion and doubly-vergent crustal wedges, thoroughly analized by means of numerical methods (MatPIV tool). My intention is to complement the aforementioned approach with a palinspastically restored structural cross-section at the western slope of the Southern Central Andes at c. 34°S. My ultimate goal is to combine the analog modeling with structural thermochronology, establishing relationships between mass balance, wedge geometry and rock uplift rates, towards a comprehensive and robust understanding of the Southern Central Andes as a crustal-scale doubly vergent wedge. Thus, further learning regarding how deep tectonic processes and surficial factors are combined, and how their interplay greatly modifies mountain building is at the core of my research, as well as for the development of my career as a geologist.
I believe I can contribute greatly to the courses' development. I have the basic skills regarding the course scope; I have a strong basis in structural geology and experience with numerical programming software (Matlab). I am familiar with the literature regarding deformation-erosion interplay, and I intend to go in depth into this subject during my doctoral research and further studies (plans for a postdoc at the US). Last, but not least, I am a sociable person who is eager to develop team-work and learn from other Earth scientists.
Sincerely,
Sebastian

I'm a graduate student major in geodynamics. My research is about using numerical modeling to study strike-slip fault and landscape effects on river offsets. I want to attend the meeting to show the results and communicate with other researchers about the implications of my results. What's more, I want to learn some frontier numerical techniques and how to use these numerical models to solve problems. +
I'm a member of the CIG Science Steering Committee and have developed numerical models in glaciology and long-term tectonics. I would like to discuss coupling objectives and challenges from a scientific and computational perspective. +
I'm interested in the coupling of tectonic, erosion and climate processes. Currently I'm working on a project that focuses the spatial pattern of glacial erosion in mountain ranges. I’m using a numerical model (Parallel Ice Sheet Model) to simulate the glaciation in mountain belts under various climatic conditions. My goals for this meeting are 1) learning some state-of-the-art numerical techniques that simulate tectonic processes in mountain ranges, 2) developing ideas of coupling tectonic process models with the ice sheet model I’m using, 3) learning techniques of model-field data comparison. +
I'm so excited that this workshop for coupled tectonic and surface processes is happening and have been waiting and watching for the applications to open. This last year, I've been expanding my work in surface processes into the realm of numerical modeling (mostly 2D and 3D advection-diffusion models in Matlab, but I’ve been learning Python and am interested in switching to LandLab). In my work, I focus on understanding how changing forcing on short-term, small-scale geomorphic processes adds up to drive long-term, large-scale patterns in landscape evolution. Specifically, my work generally seeks to link environmental variables (that can change with climate, internal hydrologic feedbacks, and land use decisions) to bedrock weathering, to rock strength, to patterns in landscape evolution.
For example, one of my current projects explores how grazing-induced soil erosion and the resulting change in rock-moisture patterns changed effective rock strength and the balance between hillslope diffusion and channel incision. Field observations, rock moisture data, and analysis of repeat high-resolution topographic data suggest two drastically different stable landscape states are possible. We’re using numerical modeling to explore how observable short-term patterns might play out on longer timescales, and how a bi-stable landscape might react to tectonic and climatic change.
I would love to attend this meeting as a way to further develop my skills in landscape evolution modeling, to join the discussion of how to integrate observation and modeling of processes across extremely different time and spatial scales, and to engage in the community and learn about tools others are using to explore the coupling of tectonic and surface processes. I would love to be involved in discussions and collaboration to help shape the direction this community is going. Thanks for considering my application. +
I'm working on the tectonic geomorphology and structural geology of Indoburman Range and interested in applying model to investigate the formation and surface processes of this area. Therefore, this workshop will be very useful my research. +
In my research I am deducing information from the morphological characteristics of a landscape in order to reconstruct tectonic history. The ratio of the amount of stream power used to transport sediment as opposed to that used for incision varies as a function of the geomorphological position within a landscape and correlates with dynamic characteristics, such as the rate of channel and divide migration or the frequency of channel captures. Reading the topographic features left behind by these processes provides additional information about the nature of the tectonic processes, e.g. about lateral advection or uplift margin migration. Along these lines I am decoding the geomorphic evolution of the Carpathian region and would be happy to present some unique phenomena during the poster session.
I am strongly committed to theoretical research. More should be known about the nature of the transport limited dynamics, or about the explicit genesis of the erosional features we intuitively categorize in many languages as rills, gullies and valleys. Only theoretical advances enable an enhanced level of the interpretation of landscapes. However theoretical advances are often hampered by the lack of qualitative capacity of models. Setting the direction of future development of models can also be a fruitful outcome of this meeting. +
I’m an early career researcher working at the Istituto Nazionale di Geofisica e Vulcanologia. My research interests are active tectonics and earthquake geology, with a focus on tectonic geomorphology. I'm particularly interested in high-resolution topography (especially LiDAR and Structure from Motion (SfM) Photogrammetry), in the study of fault zones structure and geomorphology and in earthquake surface ruptures.
I’ve been busy over the past year working on the analysis of near-fault and far-field geological surface effects produced by the Mw 6.0 - 6.5 2016 central Italy seismic sequence (Amatrice, Visso and Norcia earthquakes). In particular, the impressive and complex pattern of surface faulting produced these earthquakes raised a considerable interest in the study of the short-term morphologic evolution of fresh coseismic ruptures during the immediate postseismic and interseismic phases.
I recently had the opportunity to start a project with other INGV colleagues to monitor the surface expression of the fault system responsible for the 2016 central Italy surface ruptures (Mt. Vettore - Mt. Bove fault system) and of selected active faults in the Abruzzi and Umbria regions (central Apennines), in order to detect their short-term morphological evolution and possible coseismic and postseismic dislocation through repeated high-resolution topographic (LiDAR and SfM) surveys and ground based Synthetic Aperture Radar interferometry.
Fault scarps and associated offset geomorphic markers form and evolve due to the competition between tectonic slip during the coseismic phase and erosional/depositional processes prevailing during the interseismic phase. Thus, tectonic landforms morphology reflects not only on the repeating occurrence of slip along a fault but also on the degradational processes that modify its original shape.
In this framework it is essential to monitor in detail the morphologic evolution of fresh coseismic ruptures since they trigger a plenty of moulding surface processes in response to the topographic anomalies produced by sudden tectonic forcing. Understanding such morphologic evolution can lead to a better interpretation of the cumulative expression of a surface rupturing fault. Understanding the morphologic evolution of fault scarps will be useful for the reckoning of long-term erosional and depositional rates that impact on the long-term slip-rate and slip distribution estimates derived by the sole morphological offsets. In fact, a multi-temporal monitoring of near-fault surface processes is crucial for the validation of recent techniques that estimates slip-rate and paleoseismological record on active faults on the base of cosmogenic dating methods of the bedrock fault scarp exposure.
I think attending the workshop would be beneficial to develop collaborations with researchers working on the coupling between tectonics and surface processes, in particular with those working on the relationship between climate-influenced erosion and long-term exhumation of rocks and also with the geochronology community.

My PhD project (under Taras Gerya’s supervision) is about understanding oroclines formation and evolution using numerical modelling of both surface and deep processes. I am performing large scale simulations of narrow retreating subduction zones over long (Ma) time scales. I am using I3ELVIS thermomechanical code coupled to a diffusion/advection code for surface material (FDSPM). Assessing the respective roles and interactions of slab retreat mechanics and material displacement at the surface of the models is central to my project. Meeting with researchers from the CIG and CSDMS communities to discuss different techniques of coupling tectonic and landscape evolution modelling is of particular interest to me. Getting feedback on the modelling technique I am using and how to further develop it would also be very useful. +
My PhD projects involve the study of surface processes in coastal areas. I investigate the landform dynamics as a result of local interactions and feedbacks among hydrodynamics, vegetation, and sediment transport. I use remote sensing, field measurements and numerical modeling as main tools. I have implemented a large-scale physics based model to answer the question of “how do upland and estuarine characteristics influence coastal wetland distribution and resilience to future changes?”. For my future research as a postdoc, I will be studying the surface processes of steep mountain rivers to explore mountain landform evolution, sediment formation and transport from source to sink in coastal zones. This workshop will be a unique opportunity to prepare me for my postdoc research. It helps me develop skills that are necessary for numerical modeling of tectonic processes corresponding to mountain formation at small and large scales. Besides the training aspect of this experience, this workshop will be a great opportunity to extend my professional connections in new disciplines (e.g. surface processes of other landforms and tectonic processes) by meeting and interacting with other scientists. In short, this collaboration opportunity will be key to reaching my goals and in building my future career path in Science. +
My dissertation is focused on landscape evolution in continental extensional settings, principally on how fluvial settings responding to active extension. +
My interest in attending is based on an interest in coupling long-term (> 10 Myr) lithospheric dynamics simulations with surface processes. From a technical standpoint, the primary question I am interested in are the relative benefits of coupling between distinct codes verse adding new features to existing lithospheric dynamics codes. The relative benefits in question range from HPC performance to the physical accuracy (e.g., robustness) of different surface process approximations. An additional topic of interest is thermodynamic self-consistency in modeling sedimentation within lithospheric dynamics codes. +
