Document Summary
River systems and landforms: fluvial processes and landscapes, floods and river management. Fluvial processes and landforms: base level of streams, drainage basins, drainage density and patterns. Base levels: ultimate base level = sea level ocean, dams create a sediment to accumulate in response to stop the flow to the ocean, long profile steep elevation at the top, can map the elevation. Drainage basins: makes it way by a variety of access points, drainage divide. Drainage patterns: dendritic looks like the veins on a leaf, trellis, radial, parallel, rectangular, annular, deranged one lake drains into another, they change overtime, drainage capture, change from low elevation to higher elevation. Streamflow characteristics and associated processes: source water, flow velocity, measurement discharge, hydrograph, stream erosion, stream transport, flow and channel characteristics, stream gradient, stream deposition. River discharge: how much water moves by a certain point given, (average velocity) width x average depth.
