Other program language
Code optimized	Single Processor
Multiple processors implemented
Nr of distributed processors
Nr of shared processors
Start year development	2003
Does model development still take place?	Yes
If above answer is no, provide end year model development
Code development status
When did you indicate the 'code development status'?
Model availability	As code
Source code availability (Or provide future intension)	Through CSDMS repository
Source web address
Source csdms web address
Program license type	Apache public license
Program license type other
Memory requirements	Standard
Typical run time	hours-days

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
Other output format
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	None
Upload calibration data sets if available:
Describe available test data sets	None
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.

This part will be filled out by CSDMS staff

OpenMI compliant	No but possible
BMI compliant	Yes
WMT component	Yes
