Erosion is the wearing away of the land surface by running water, wind, ice, or other geologic agents, including such processes as gravitational creep. The term geologic erosion refers to the normal, natural erosion caused by geological processes...

Erosion is the reduction or breakdown of landforms exposed to the forces of weathering (disintegration and decomposition). Weathering and subsequent erosion may be caused by both chemical or mechanical forces. Mechanical weathering agents include wind,...

Soil loss tolerance is the maximum average annual soil removal by erosion that will allow continuous cropping and maintain soil productivity (T). It is occasionally defined as the maximum amount of soil erosion offset by the maximum amount of soil...

Removal of surface layers of materials such as soil, sediment or rock from the land by the action of water, ice or wind. The process is distinct from WEATHERING as the former simply transports materials from their site of origin to another place, while...

Erosion is displacement of solids (sediment, soil, mud, rock and other particles) usually by the agents of currents such as, wind, water, or ice by downward or down-slope movement in response to gravity or by living organisms (in the case of...

Erosion caused by dredging and other human activities on the St. Clair River is causing Lakes Huron and Michigan to lose 2.5 billion gallons of water daily, according to a private Canadian study.Like a bathtub drain, the artificially deepened river is funneling vast amounts of...

Under pressure from Congress, a U.S.-Canadian agency Thursday agreed to quicken a study of whether erosion from dredging on the St. Clair River is causing water levels to plummet in Lakes Huron and Michigan.The International Joint Commission said it would submit a series of updates...

Video images from the St. Clair River bottom show no evidence that erosion is causing water levels on Lakes Michigan and Huron to drop, scientists working for a U.S.-Canadian advisory group said Thursday.Although preliminary, the findings intensified a debate over whether people or nature are...

A federal study beginning this month will examine how much the Savannah River's bustling shipping channel contributes to beach erosion on Tybee Island.The $411,700 study by the U.S. Army Corps of Engineers will also look at how much the federal government will need to pay...
