Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Lateral vs. Vertical Incison in alluvial channels. Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 1.5D Spatial extent Landscape-Scale, Watershed-Scale, Reach-Scale Model domain Terrestrial 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 Keywords: Meander center line, river, Name Luca Malatesta Type of contact Model developer Institute / Organization UC Santa Cruz Postal address 1 Earth & Planetary Sciences Department Postal address 2 1156 High St. Town / City Santa Cruz Postal code 95064 State California Country United States Email address lcmalate@ucsc.edu Phone Fax Supported platforms Linux, Mac OS, Windows Other platform Programming language Matlab Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 2013 Does model development still take place?

No If above answer is yes Other visualization software 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.
