Rainfall patterns and drainage density
This activity has benefited from input from faculty educators beyond the author through a review and suggestion process.
This review took place as a part of a faculty professional development workshop where groups of faculty reviewed each others' activities and offered feedback and ideas for improvements. To learn more about the process On the Cutting Edge uses for activity review, see http://serc.carleton.edu/NAGTWorkshops/review.html.
This activity was selected for the On the Cutting Edge Reviewed Teaching Collection

Skills and concepts that students must have mastered
Students must understand how to interpret slope, contour, and hillshade maps and blue lines on maps.
Students must know how to use ARC GIS to make slope, contour, and hillshade maps and to create river shape files with different drainage area thresholds.

Description of the activity/assignment
Designed for a geomorphology course
Uses online and/or real-time data
Determining whether students have met the goals
1. Channels are in the locations where contours point uphill
2. Steep slopes on either side of a flat area illustrates a canyon
3. Canyons are often shaded on one side and illuminated on the other in a hillshade map
4. Precipitation patterns affect drainage density
