soils vulnerable to water erosion. Sheet erosion detachment of soil particles by raindrop impact , their removal downslope by water flowing overland as a sheet instead of in definite channels rills.
Erosion: Movement and Relocation. The rock fragments and soil - - sometimes as small as tiny sand particles - - are carried away by wind, water or irrigation. Weathering causes changes in the rock, such as color variations or decomposition, but erosion only moves the sediment from one place to another. Like the definition for alluvium, the English Wikipedia definition for colluvium includes rainwash and sheetwash. However, this definition adds downslope creep as a possible process, which shifts the main driver towards gravity.

Of course, gravity drives water erosion, but there is an important difference between sediments transported by. Headward erosion results when a valley is extended upward above its original source by gullying, mass wasting, and sheetwash flow. Lateral erosion occurs when the stream meanders or braids back and forth across its valley floor or channel, undercutting and eroding its banks.
