Coastlines – erosion that occurs on coastlines is due to the action of ocean currents, waves, and tides. Hydrograph, location map, and photograph of rainfall-runoff event August 27, 1982, illustrating ephemeral stream channel transmission losses as measured within the Streams can reduce the pollution that flows to downstream rivers, lakes, bays, and coastal waters. A major source of water in rivers in the Southwest is from groundwater released into streams that only flow part of the year. Selected Answer: are a major agent of erosion in desert regions Correct Answer: are a major agent of erosion in desert regions Question 2 2 out of 2 points What is the volume of water that passes through each part of the hydrologic cycle annually called?

Streams and Rivers – erosion commonly occurs along the bank of the stream. channel form, flows and sediments - of endogenous ephemeral rivers in deserts; water, a significant agent - of erosion in arid lands; desert streams, differing from their perennial counterparts - propagation of flood waves; flash flood hydrograph; ephemeral river channel geometry - desert streams, and their great width; fluvial sediment transport; All streams start at some high point. general-geography A stream is a body of concentrated flowing water in a natural low area or natural channel on the land surface (15A NCAC 02B .0233(2)). Erosion : A video lab over erosion Water Erosion.
