- Cosmogenic: production rate, decay rate, attenuation, density diffusive erosion rate drainage basin size, critical drainage area for a channel
- River channel scaling parameters: width, sediment depth, drainage density

Process
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.

Model description
Model type:
|
Single model for the terrestrial domain.
|
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.
