Document Summary
A stream normally stays in its stream channel, a long, narrow depression eroded by the stream into rock or sediment. The movement and interchange of water between the ocean, atmosphere, stream a body of running water that is confined in a channel and moves downhill under the. Stream banks are the side of the channel. Sheetwash a thin layer of unchanneled water flowing downhill. If the pattern of drainage resembles branches of a tree or nerve dendrites, it is called. Sheet erosion occurs when a thin surface layer, usually comprising topsoil soil, is washed away by a sheet of water. This is usually produced by sheetwash, which develops when a thin layer of unchanneled water flows over the landscape. dendritic. Drainage basin refers to the aggregate area over which a stream and its tributaries drain. A radial pattern, in which streams diverge outward like spokes of a wheel, forms on high conical mountains, such as composite volcanoes and domes.
