Document Summary

Everything we do in class tonight on avalanches is all we will ever do on avalanches (don"t focus on doing an entire chapter in the textbook) Only two things that apply (for select all question on quiz) Resisting or sheer strength, over the driving forces. The coarser the material, (or larger the grain size), the higher the angle of repose. As angle increases angle of repose increases. As the moisture content increases, the angle of repose increases until you"ve reached saturation (with respect to moisture content) ^ when one sand grain is touching another sand grain, the friction keeps those grains together, ^ if you add a little bit of water, still grain to grain contact, and surface tension of water holding it together. ^ when you have too much water, it adds too much pressure to the grain and it causes everything to collapse (there is no more grain to grain contact)
