GEOB 103 Study Guide - Erosion, River Source, Stream Gradient
Document Summary
Fluvial geomorphology is the study of erosion, transport and deposition ofsediment primarily under the influence of flowing water. In comparison, mass movements refer to the erosion, transport and deposition of sediment primarily under the influence of gravity. Things like debris flows that occur in streamchannels and involve aspects of both flowing water and gravity are right on the boundary between fluvial and mass movement processes. Division of a drainage basin based on dominant processes. We can divide a stream channel network (or watershed) into 3 zones, based on whether fluvial erosion, transportation or deposition is the dominant process. The degree to which the stream channel network (where most of the work of flowing water is done) is coupled with mass movement processes changes systematically. We will explore the division of a watershed and the interactions between mass movements and fluvial processes using a local example.
