GEOG 120 Lecture Notes - Lecture 15: Denudation
Document Summary
Fluvial landforms: describe the main aspects of ground water and overland runoff, explain the basics of stream flow and flooding, discuss how fluvial erosion and deposition occur, describe typical landforms created by fluvial processes. Denudation wearing down of rocks (the overarching term) Processes of erosion, transport, deposition. Water flowing across the surface picks up and carries materials. Includes overland flow and stream flow. Dominant force of landscape formation. Col, peak, ravine, spur, canyon. Channeled flow a method by which materials are moved. More energy as the flow is focused see textbook for channel movement diagram. Shows that stream flows have suspended loads, dissolved loads, rolling loads and sliding loads. Bed load is transferred by rolling or sliding depending on the velocity of the water. Saltation: the bouncing and moving of the bed materials. Turbulence is what keeps the suspended load from settling. Morphometry- the shape of the overall channel/stream as it changes. Made up of undulations and slopes.
