GEOLOGY 1 Chapter Notes - Chapter 9: East Los Angeles College, Suspended Load, Stream Gradient
Document Summary
For more than 200 years, americans have lived and worked on floodplains, depending on soil, water supply, ease of waste disposal, and commerce. If the flood plain and its relation to the river are not recognized, flood control and drainage of wetlands become prime concern. The pioneers moved west modifying the land: cutting and burning the trees, and then modified the natural drainage of the area. Stream total load: total amount of sediments. Bed load: coarse particles moving along the bottom of river channel- less than. Suspended load: accounts for about 90% of its total load and makes river look muddy. Competence: measuring the max size of the sediments transported by a river. Capacity: totoal amount of sediments in the river. Gradient: vertical drop over horizontal flowing distance, expressed in %, ft/mi, or degree of the slope. Stream velocity: largely dependent on stream gradient, discharge, channel shape, and turbulence.
