In/Output
| 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.)

No
|
| Describe pre-processing software
|
|
| Post-processing software needed?
|
Yes
|
| Describe post-processing software
|
RiverTools or a similar program can be used to create animations of the grid sequence.
|
| Visualization software needed?
|
Yes
|
| If above answer is yes
|
|
| Other visualization software
|

|
Process
| 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:
Q = R * A^p
Qs = Kf * (Q^m) * (S^n),
2D mass conservation equations for water and sediment
|
| Describe length scale and resolution constraints
|
Typical grid cell dimensions are 10 to 500 meters.
|
| Describe time scale and resolution constraints
|
Typical simulated time is 1000 to 100,000 years.
|
| Describe any numerical limitations and issues
|
D8 flow codes are used to compute contributing areas. Would be better to use D-Infinity or the Mass-Flux method.
