Test your hypothesis. How did your prediction compare to the result of your simulation? Exercise 4: Reproducing the Grand Canyon The default values for WILSIM-GC were chosen for two reasons: They approximate the values of the geologic properties they are simulating, and The simulated canyon that develops with these values is a close approximation of the Grand Canyon. However, as you have seen, the model parameters interact with each other in ways that amplify or counteract each other's effects. Can you create a landscape similar to the Grand Canyon, using values significantly different than the default values of the model? Aim to produce a simulation that has an output or result similar to the simulation output of the default values. Play around with the parameters to see how close you can get to producing a similar landscape with different values. Save or print out the results from your best approximation and write the parameter values you used on the images. Exploration: Explore the model at your own rate. Set the parameter values to your choosing, make a hypothesis, and run the model. Change the end time of the simulation to see what could happen in the future. Discover the power of using a simulation to understand landscape evolution.
