GEOG 101 Lecture Notes - Lecture 20: Aggradation
Document Summary
Fluvial geomorphologists are concerned with fluvial landforms and processes. A thin film of water flowing over the surface. Found at the very tops of slopes. Impermeable surfaces (instantaneous runoff: waters in rivers provided by: All process lead to the creation of a graded river channel. Layers of rock that are more resistant to erosion than others. Lengthens the time it will take for a graded channel to be created. The build up of sediment in the system. Water that is released contains less sediment. Clearer water had a greater ability to erode: drainage basins. An area drained by a single river. All precipitation caught in that certain drainage basin will exit through that particular river. The further you go up a basin, the less developed the water system is. Divide individual sub-watersheds of a drainage basin. All of these terms = the drainage system. Factors that determines how much water there is in a drainage basin.
