WebThe blue line shows how erosive energy is concentrated along the outside of each bend in the stream. As erosion occurs on the outside bank of a meander, deposition occurs on the inside bank where the water slows and drops sediment. ... In a stream, meanders enlarge and migrate downstream because the stream continually erodes its cut banks and ... WebBase Level The lowest point to which a stream can erode. Ultimate base level is deﬁned by the position of sea level. Streams cannot erode below sea level. A lake serves as a local (or temporary) base level. Base level changes cause stream re-adjustments. Raising base level results in an increase in deposition. Lowering base level accelerates erosion.

WebAs a stream gets closer to base level, its gradient lowers and it deposits more material than it erodes. On flatter ground, streams deposit material on the inside of meanders.

WebWhat is river and stream erosion? Streams erode and transport sediment. As the loose sediments are moved along the bottom of the river channel, small bedforms (formations of sediment on the bottom of the stream bed) can develop, such as ripples and sand dunes. The total load (quantity of sediment) of a stream can be described as consisting of ... Webwhich in turn means higher stream-bank erosion rates.
