Using the "Simulation End Time" Parameter in WILSIM-GC to Model the Shape of the Grand Canyon in the Past and Future

Kyle Whalley, Geography, Northern Illinois University
Author Profile


In this exercise, students use the computer simulation WILSIM-GC to explore what the Grand Canyon might look like in the future, assuming that the processes that have shaped it until now continue at similar rates.

Learning Goals

Content Goals

After successfully completing this exercise, students will be able to describe how the "simulation end time" parameter in WILSIM-GC influences the model output.

Higher Order Thinking Skills

Students formulate and test hypotheses.

Other Skills

Students learn to manipulate the parameters of the computer simulation WILSIM-GC.

Context for Use

Course Type

Undergraduate course in geography or geology

Prerequisite Skills

This is an introductory parameter exercise that requires no additional skills. A basic background in fluvial erosional processes and landform evolution is recommended.

Where this activity fits in the course

This is a stand-alone exercise that can be used as an introduction to WILSIM-GC, a computer simulation. Having completed this exercise, students will be ready to use WILSIM-GC to do more sophisticated activities, exploring and discovering principles of fluvial geomorphology.
