Erosion is the wearing down of a landscape over time.It includes the detachment,transport,and deposition of soil particles by the erosive forces of raindrops and surface flow of water.
A land area contains rills and channels.Raindrop impact can detach soil particles on unprotected land surfaces between rills and initiate transport of these particles to the rills.From the small rills,the particles move to larger rills,then into ephemeral channels and then into continuously flowing rivers.Entrainment and deposition of particles can occur at any point along the path.When erosion occurs without human influence,it is called geologic erosion.Accelerated erosion occurs when human activity increases the rate of erosion.
Erosion is a matter of concern to watershed and natural resource managers.Two of the main reasons reservoirs are built are water supply and flood control.Erosion upstream of a reservoir deposits sediment in the bottom of the reservoir which lowers the reservoir’ water-holding capacity and consequently its usefulness for both of these purposes.The soil surface is the part of the soil profile highest in organic matter and nutrients.Organic matter forms complexes with soil particles so that erosion of the soil particles will also remove nutrients.Excessive erosion can deplete soil reserves of nitrogen and phosphorus needed by plants to grow and extreme erosion can degrade the soil to the point that it is unable to support plant life.If erosion is severe and widespread enough,the water balance of a watershed can be altered-remember that most water is lost from a watershed via evapotranspiration.

水土流失是身穿景观降下来.它包括支队,运输,由雨滴和地表水流的侵蚀力量和土壤颗粒沉积.
甲土地面积包含潺潺和渠道.雨滴的影响可以不受保护的土地上分离土壤颗粒的表面间潺潺,并开始对这些粒子运到潺潺.来自小潺潺,粒子移动到更大的潺潺,然后进入短暂的渠道,然后进入奔腾不息的河流.拖带和沉积颗粒可能发生在任何沿路径点.当破坏,如果没有人类影响时,它被称为地质侵蚀.当加速侵蚀人类活动增加侵蚀率.
水土流失是一个关注的问题流域和自然资源管理.对水库的主要原因有两个是建立供水和防洪.侵蚀上游水库存款的水库从而降低水库'持水能力,因而它的这些目的都用处底泥.土壤表面的土壤剖面中的有机物质和营养的最高部分.有机质的形式与土壤颗粒物,使土壤颗粒侵蚀也将删除养分.过度磨损可能耗尽氮和植物生长所需的磷和极端侵蚀土壤储备可降解土壤中的一点,它无法支持植物生命.如果侵蚀严重和普遍不够,一个流域水平衡可以改变记忆的,大部分水是从一个分水岭通过蒸发损失.
