SOIL EROSION AND SEDIMENTATION BY WATER -- AN OVERVIEW

Soil erosion and sedimentation by water primarily involve the processes of detachment, transportation, and deposition of sediment by raindrop impact and flowing water. Erosion and sedimentation are major problems that reduce the productivity of cropland, degrade water quality, carry polluting chemicals, and reduce the capacity of water conveyance structures. The erosion-sedimentation system is composed of upland and channel components. While the uplands act somewhat independently of the channels, the behavior of the channels is directly influenced by the upland inputs. Spatial and temporal variations in erosion are common with time lags in sediment yield as great as several decades. Climate, soil, topography, and land use are major factors influencing erosion and sedimentation.
