Geometric parameters of river reach and erosion capacity. +
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. +
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. +
The profiles should not be spaced too closely in order to avoid an unstable saw-tooth longitudinal profile of the river. +

Incision of a transport-limited river in a … 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.</br>The river randomly migrates left or right and needs to evacuate sediments mined from its bed and from the valley walls.</br>Product of wall erosion not evacuated by the river are deposited as taluses at the foot of the walls.sited as taluses at the foot of the walls. +
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. +

A model to explore how increasingly tall v … 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.</br>This model is used to illustrate the wall feedback concept proposed by Malatesta, Prancevic, Avouac; 2017; JGR Eath-Surface; doi:10.1002/2015JF003797JGR Eath-Surface; doi:10.1002/2015JF003797 +
