Rainwash
Rainwash, also spelled rain-wash or rain wash or sometimes called hillwash, is a process of erosion Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distin ... in which loose surface material is carried away by rainwater that has reached the surface but has not yet become concentrated into rivulets. The term is also applied to the movement under the force of gravity of material loosened by rainwater, or to the material itself. Rainwash is sometimes regarded as a combination of two processes: ''rain-splash'', which is the detachment and movement of small soil particles from raindrop impact, and ''soil-wash'', in which material is moved downslope by surface water flow.

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
