Summary Also known as Model type Single Model part of larger framework Note on status model Date note status model Technical specs Supported platforms Unix, Linux, Mac OS Other platform Programming language Fortran77, C Other program language Code optimized Single Processor Multiple processors implemented Nr of distributed processors Nr of shared processors Start year development 1995 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 owner"Through owner" is not in the list (Through web repository, Through CSDMS repository) of allowed values for the "Source code availability" property.

Description: Makes use of fast Delaunay triangulation and Voronoi diagram calculations to represent surface processes on an irregular, dynamically evolving mesh. Processes include fluvial erosion, transport and deposition, hillslope (diffusion) processes, flexural isostasy, orographic precipitation. Designed to model processes at the orogenic scale. Can be easily modified for other purposes by changing process laws. Technical information Supported platforms: UNIX, Linux, Mac OSX Programming language: Fortran77, C Model development started at: 1995 and development still takes place. To what degree will the model become available: Source code will be available Current license type: None Memory requirements: depends on model size Typical run time: minutes to hours Input / Output description Input parameters: SPM parameters (Kf, Kd, lf, etc) geomtrical and other parameters imposed by modifying the code Input format: ASCII Output parameters: H, fluxes, discharge, catchment geom, etc, at all time steps, as welle as grid connectivity Output format: ASCII Post-processing software (if needed): Yes, very limited X11 based graphic output Visualization software (if needed): Yes, interface not included Process description Processes represented by model: Fluvial erosion, deposition and sedimentation, hillslope (diffusion) processes, flexure, orography Key physical parameters & equations: see Braun, J. and Sambridge, M., 1997.

Length scale & resolution constraints: Large scale (100 km+) model, suitable for orogenic scale modeling but could easily be adapted Time scale & resolution constraints: Evolution of Myrs, due to the model parameterization used (no human-scale proceses) Numerical limitations and issues : Limited to medium-size resolutions.
