Model:WILSIM

WILSIM

Also known as
Model type	Single
Model part of larger framework

Incorporated models or components:

Spatial dimensions	2D
Spatial extent	Watershed-Scale
Model domain	Terrestrial
One-line model description	Landscape evolution model
Extended model description	This is a Java Applet that allows the user to change different parameters (such as rainfall, erodibility, tectonic uplift) and watch how the landform evolve over time under different scenarios. It is based on a Cellular Automata algorithm. Two versions are available: linear and non-linear. Details can be found in: Luo, W., Peronja, E., Duffin, K., Stravers, A. J., 2006, Incorporating Nonlinear Rules in a Web-based Interactive Landform Simulation Model (WILSIM), Computers and Geosciences, v. 32, n. 9, p. 1512-1518 (doi: 10.1016/j.cageo.2005.12.012).
