| 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. |

| Process description model | |
|---|---|
| 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. |
