This short test is designed to measure the users’ level of understanding of the basic process that control landform development after using WILSIM. When taken in conjunction with the PRE-TEST it will allow the WILSIM designers to determine how effective the model is as an educational tool.

1. What is the definition of "Runoff"?

2. What is necessary in order for Runoff to occur across the land surface?

3. What is the definition of a drainage network or drainage system?

4. Concerning the time frame over which drainages develop, why are numerical models such as WILSIM so valuable?

5. When flowing water erodes the land surface to create a drainage network, do these drainages always develop at the same rate everywhere in nature or in a computer model?

6. What do you think the best definition for "erodibility" would be?

7. The term “Tectonics” refers to which of the following?

8. Which of the following do you think would be the primary variable that controls the rate of drainage network development?

9. WILSIM can also simulate the affects of climate change upon drainage form or morphology over time (i.e., initially dry then evolving into a wetter climate or vice versa). How do you think climate change would affect drainage morphology?

10. Define Cross Section in a geographic sense.

11. What is a Hypsometric Curve?

12. Where in the landscape do you think the deposition (accumulation of eroded and transported sediments) would most unlikely to occur?

13. If all variables for two model runs are identical, why do dendritic drainages develop in different locations and with slightly different morphologies across the landscape grid?

14. Can WILSIM effectively model the degree of vegetation cover?

15. What do the hypsometric integrals as implemented in WILSIM tell you about the drainage network and the elevation changes through time?
