Incorporated models or components:
Spatial dimensions 2D
Spatial extent
Model domain Terrestrial
One-line model description 2-D model tracking cosmogenic nuclides and mixing in landslide terrain
Extended model description The model tracks both surface CRN concentration and concentration eroded off hillslopes into fluvial network in a simplified landscape undergoing both landslide erosion and more steady 'diffusive-like' erosion. Sediment mixing is allowed in the fluvial network. Code can be used to help successfully develop CRN sampling procedures in terrains where landslides are important.

Describe processes represented by the model Tracking of cosmogenic nuclides on surface and in fluvial system of a landslide dominated drainage basin
Describe key physical parameters and equations Cosmogenic nuclide production decay with depth. Power-law distribution of landslide size. Calculates a fluvial storage reservoir.
Describe length scale and resolution constraints Drainage basin size controls the length of the model runs. Cell size should not be increased to shorten model runs.
Describe time scale and resolution constraints Yearly timesteps. Most runs go for 500,000 yrs or more.
Describe any numerical limitations and issues Matlab may max out memory if drainage basin is too large. Since this is a simplified landscape with wrap-around boundary conditions, one workaround is to do numerous smaller runs and add the output.
