Mid-level spreadsheeting and complex modeling of real-world scarp evolution part of Quantitative Skills:Activity Collection
William Locke, Montana State University-Bozeman
This exercise is a second or familiarization exercise in spreadsheeting, but is also a mathematical model for slope evolution. It uses the concept of "erosivity" (generally, the relative ratio of driving and resisting forces) and slope angle to reshape an initial topography. Finally, it asks the students themselves to come up with a real-world situation worth modeling.
