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.)
Input format
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.
Output format Binary

Pre-processing software needed? 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 Rivertools


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.


Describe available calibration data sets
Upload calibration data sets if available:
Describe available test data sets
Upload test data sets if available:
Describe ideal data for testing [[Describe ideal data::Same as used for other LEMs, like CHILD and MARSSIM.]]


Do you have current or future plans for collaborating with other researchers? See comments below.
Is there a manual available? No
Upload manual if available:
Model website if any
Model forum / discussion board
Comments I currently have an NSF-CMG grant to work with Greg Tucker, Tom Manteuffel and Steve McCormick to find faster algorithms for this type of model.
