Web-based Interactive Landform Simulation Model-Grand Canyon

Welcome to the Web-based Interactive Landform Simulation Model-Grand Canyon (WILSIM-GC) website! The Grand Canyon is one the most spectacular landforms on Earth. Have you ever wondered how it formed? WILSIM-GC is an inquiry-based educational tool designed to help undergraduate students understand and visualize the geologic processes that interacted to form the Grand Canyon over the past 6 million years. Please join our email list to find out about updates.

Start Using WILSIM

To begin using WILSIM, we recommend you read these pages:

  • Introduction to WILSIM-GC: an introduction to the development of the Grand Canyon, how WILSIM-GC simulates that development, and the parameters that WILSIM-GC allows you to vary
  • Start Using WILSIM-GC: how to install and run the model
  • Example Simulations: a couple of suggested simulations, and an introduction to the cross-sectioning tool

You may also enjoy exploring WILSIM-CA: our original, cellular automata model.
