Model:CASCADE

CASCADE

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.
