Document Summary
River or lake is a natural local base level. Reservoir behind a damn is a human-caused local base level. Sheetflow: thin film spread over the ground surface. Concentrate in rills: small-scale grooves in the landscape made by the downslope movement of water. Rills may develop into deeper gullies and then into stream channels leading to the valley floor. Interfluve: high ground that separates one valley from another and directs sheetflow: ridges act as drainage divides that control into which basin the surface runoff drains. Continental divides: separates drainage basins that empty into different bodies of water surrounding a continent. Slope erosion processes: fluvial landforms: landforms shaped by running water, erosional landforms. Landforms shaped by the removal of regolith or bedrock by erosion: depositional landforms. Landforms made by the deposition of sediment: splash erosion. Soil removed in thin uniform layer: rill erosion. Numerous closely spaced tiny channels scored into soil and regolith: colluvium.
