2. Importance of unique events/thresholds Discrete vs. continuous processes Storms Disturbance Landslides Debris Flows

3. Critical Distance from drainage divide = channelization 6. How and where are channels initiated on slopes?

4. Rain splash

5. Where flow is thin, rainsplash disturbance prevents channelization Incision begins when shear stress exceeds strength

7. Hillslope- channel transition, colluvial hollows

9. 5. Explain two biologic effects on soil strength and erosion.

10. Other biotic effects - vary by climate and location 3

13. 4. Describe the physical characteristics of debris flows and the deposits they leave.

14. 3. Describe how slope stability is modeled for planar and rotational slides. http://ees.as.uky.edu/sites/default/files/elearning/module11swf.swf

15. FORCE BALANCE GRAVITY SHEAR STRENGTH (FRICTION AND COHESION or VISCOSITY) DRIVING VERSUS RESISTING

18. Rotational failure - clay, silt, homogeneous material

20. 2. What is cohesion and why is it important geomorphically?

21. 1. Predict the effect of a heavy rainstorm on slope stability and explain the reasoning behind your prediction.
