{{Meeting statement interest
|Meetingstatement_of_interest_submit=The coupling of surface process models with lithospheric deformation models lies at the heart of two of my current projects, with Lucile Bruhat on one side and with Jean-Arthur Olive, Mark Behn and Roger Buck on the other. In the first one, a model for wave-base erosion is coupled to a reconstruction of the interseismic deformation over the Cascadia subduction zone to identify the morphological signatures of fault coupling. The second project (ongoing since 2013) seeks to establish the evolution of normal faults under varying climatic and lithospheric conditions. In it, we couple a 2D horizontal landscape evolution model to a 2D vertical visco-plasto-elastic geodynamic model of the lithosphere.
My background is in geomorphology and my collaborators are geophysicists. The very questions that will be discussed at the CSDMS workshop reflect thoughts and discussions I have with them. I would be very interested in taking part in the workshop to better integrate the community that spans the interface between geodynamics and geomorphology and participate in the discussions that will potentially shape the path forward. I am a postdoctoral researcher at UC Santa Cruz after finishing my PhD at Caltech in 2016.

{{Model identity2
|ModelDomain=Terrestrial
|Spatial dimensions=1.5D
|Spatialscale=Landscape-Scale, Watershed-Scale, Reach-Scale
|One-line model description=Geometric model to explore autogenic increase of vertical incision rate in entrenching alluvial rivers.
|Extended model description=A model to explore how increasingly tall valley walls constrain the river lateral erosion and promote vertical incision. Each run is unique as a random walk controls the lateral migration of the channel. To store and compare repeated runs with identical parameters, there is a built in system to save the results of each run.
This model is used to illustrate the wall feedback concept proposed by Malatesta, Prancevic, Avouac; 2017; JGR Eath-Surface; doi:10.1002/2015JF003797

{{Process description model
|Describe processes represented by the model=Incision of a transport-limited river in an alluvial substrate. Initial geometry is that of a steep channel with sediment transport capacity exceeding that of the input flux from upstream.
The river randomly migrates left or right and needs to evacuate sediments mined from its bed and from the valley walls.
Product of wall erosion not evacuated by the river are deposited as taluses at the foot of the walls.
|Describe key physical parameters and equations=The model uses geometric laws that mimic the behaviour of Meyer-Peter Mueller (1948) sediment transport capacity laws as a function of slope and width.
|Describe length scale and resolution constraints=The model is made of a series (5 to 100) of across-river profiles to model a river reach ca. 5 to 50 km in length and 1 to 20 km in width.
|Describe time scale and resolution constraints=There is no explicit time, every time step is a bankfull event. With the parameters published here, vertical incision rates correspond to rates on the order of cm/yr.
|Describe any numerical limitations and issues=The profiles should not be spaced too closely in order to avoid an unstable saw-tooth longitudinal profile of the river.

|MOI summary=The 2016 version of the European little cousin of the Gilbert Club Meeting (one extra day of geomorphology after the xGU conference).

There will be space to hang the posters you presented earlier in the week and discuss them more over coffee and lunch. We will finish the day with a general discussion/pop-ups when you will have the opportunity to share thoughts and observations and briefly present a couple of slides.

Talks:
Josh West (University of Southern California):
"The imprint of erosion on chemical weathering, and its relevance for the long-term carbon cycle and climate"

Sanjeev Gupta (Imperial College London):
"Reconstructing ancient landscapes on Mars: Curiositys exploration of Gale crater"

Michele Koppes (University of British Columbia)
"When do glaciers shape mountains?"
