Model description
| Model type: | Single model for the terrestrial domain. |
| 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. Basin Research, v. 9, pp.27-52. |
| 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. Typical runs 256x256 |

User groups
| Currently or plans for collaborating with: | Used by several collaborators in a variety of modified versions, adapted to each one's needs |
Documentation
| Key papers of the model: | Little, mostly in the code itself |
| Is there a manual available: | no |
| Model website if any: | No, available on request |
