{{Input - Output description | |||
|Describe input parameters=Initial land surface (several built-in options), number of timesteps, DEM grid dimensions, DEM grid cell dimensions, R = "geomorphic" rainrate (m/yr), U=uplift rate (mm/yr), BLR = base-level lowering rate (mm/yr), Kf="erodibility coefficient (m^3/yr)^(1-m), m = area/discharge exponent, n = slope exponent, p = area-discharge exponent, toggles for different types of boundary conditions (e.g. periodic), DEM georeferencing info (bounding box, pixel geometry, etc.) | |||
|Other input format=Command line | |||
|Describe output parameters=A sequence of grids that represent DEMs at different times in the evolution. Saved in RTS (RiverTools Sequence) format with RTI file for georeferencing. | |||

}} | |||
{{Process description model | |||
|Describe processes represented by the model=Sediment transport (parameterized with slope and contributing area grids), rainfall, uplift, base-level lowering. | |||
|Describe key physical parameters and equations=The main equations are: | |||
