SOIL EROSION: CAUSES AND MECHANISMS: PREVENTION AND CONTROL

When man disturbs or modifies the surface of the ground, the soil may erode. The effects are not confined to the site of the disturbance; sediment is washed into nearby streams, then into rivers and reservoirs, representing what most authorities call the largest single stream pollutant. Physical damages from sediment include reservoir silting and resultant loss of storage capacity; filling of harbors and navigation channels; altering of morphology and stability of stream channel systems; and clogging of drainage ditches, culverts, and underflows along highways. Sediment restricts recreational use of water and disrupts stream ecology. Ultimately, erosion and sediment are expensive problems. The report is presented in two parts. Part One contains a state-of-the-art report along with the papers that provided the basis for panel and open forum discussions held in the first session of the conference-workshop.
