Document Summary
Debris flows: where a mass clay and rocks is then hit with a large amount of rainfall. Creep: very slow process of soil and rock moving down any hillside. Remediation: helps stop creep: drain the water, prevent infiltration of water, reduce the slope angle. H2o exists as one of 3 phases at the surface of the earth. The hydrologic cycle: water equivalent to the rock cycle consists of. Precipitation condensation as a liquid or solid. 2. 15% is in ice (glaciology, glacial geology) 0. 0091% is in lakes and rivers (geomorphology) when precipitation falls as water, there are 2 possible outcomes infiltration. Infiltration capacity: the amount of water that soaks into the ground. Wet soils = more infiltration: prior wetted condition, soil texture. Porosity = the amount of space between particles (storage) Permeability = the ability of a fluid to move between pores (transmission) larger grains: less porosity/more permeability = more infiltration. Smaller grains: more porosity/less permeability = less infiltration.
