WILSIM Introduction History Papers WILSIM Questionnaire Contact Information Model: WILSIM Contact person: Wei Luo Institute: Northern Illinois University City: DeKalb Country: USA Email: wluo@niu.edu 2nd person involved: Kirk Duffin (Technical contact) 3rd person involved: Edit Peronja (Technical contact) Model description Model type: Tool for the terrestrial domain. 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).

Technical information Supported platforms: UNIX, Linux, Mac OSX, Windows, Java Applet, Platform indepedent Programming language: Java Model development started at: 2002 and ended in 2006 To what degree will the model become available: Source code will be available, and model can be used as well as a teaching tool and it will be available as Java Applet. Current license type: GPL v.2 Memory requirements: -- Typical run time: Minutes Input / Output description Input parameters: grid size, end time, initial slope, erodibility, climate (rainfall rate), tectonic (uplift rate and break point) Input format: Applet GUI Output parameters: -- Output format: Applet Post-processing software (if needed): no Visualization software (if needed): no Process description Processes represented by model: It simulates rainfall runoff process as random storm events that fall on the initial topographic surface and flow downhill following steepest descent.
