Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions Spatial extent Model domain One-line model description Fluvial landscape evolution model Extended model description Erode is a raster-based, fluvial landscape evolution model. The newest version (3.0) is written in Python and contains html help pages when running the program through the CSDMS Modeling Tool CMT (http://csdms.colorado.edu/wiki/Help:Ccaffeine_GUI).

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 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. This part will be filled out by CSDMS staff OpenMI compliant No but possible BMI compliant Yes WMT component Yes PyMT component Is this a data component DOI model 10.1594/IEDA/100116 For model version 3.0 Year version submitted Link to file Can be coupled with:
