Also known as
Model type Single
Model part of larger framework
Note on status model
Date note status model
Spatial dimensions
Spatial extent
Model domain Terrestrial
One-line model description Large scale SPM based on irregular spatial discretization
Extended model 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.

Describe processes represented by the model Fluvial erosion, deposition and sedimentation, hillslope (diffusion) processes, flexure, orography
Describe key physical parameters and equations see Braun, J. and Sambridge, M., 1997. Basin Research, v. 9, pp.27-52.
Describe length scale and resolution constraints Large scale (100 km+) model, suitable for orogenic scale modeling but could easily be adapted
Describe time scale and resolution constraints Evolution of Myrs, due to the model parameterization used (no human-scale proceses)
