Example Simulations

If you are just getting started using WILSIM-GC, it may be helpful to run a couple of example simulations, to familiarize yourself with the model and its capabilities. Here are a few options you might try.

Use Default Parameter Values and Change Your Viewing Perspective

Follow the instructions on the Start Using WILSIM-GC page; leave all of the parameters at the default values and click on the "Start" button. Watch the Grand Canyon develop. In particular, pay attention to the migration of the knickpoint: the point on the Colorado River where it begins to cut down into the stratigraphy of the canyon.

These default values were chosen because they will result in the development of a canyon that has a morphology, or form, similar to the Grand Canyon.

Experiment with these options:


Generate a Long Profile

At the end of the simulation, a window will pop up asking you to save the data to plot a "long profile." A long profile shows elevation changes along the length of the Colorado River, within the Grand Canyon.


Generate Cross-Sections

Another way to look at canyon morphology is by selecting a cross section through the canyon as it develops. A cross section is a vertical slice. WILSIM-GC can show you cross sections through the canyon in any location. Here's how:




Use a Higher Erodibility Value

Suppose you would like to know what the Grand Canyon would look like, and how it would have developed, if the rocks that form the canyon walls were easily eroded (in essence, "softer"). In that case, you could adjust the "erodibility" of the rocks in WILSIM-GC and see how that affects the canyon.
