Ohio’s Coastal Watershed Discover Lake Erie Causes of Erosion
Causes of Erosion: Surface and Ground Water Discover Lake Erie Surface water runoff erodes a shale bluff along Ohio’s coast Shale is a fine-grained sedimentary rock consisting of silt- and clay-sized particles that easily splits into layers ODNR Office of Coastal Management Defined: Erosion is the wearing away of land and/or lakebed
GREAT LAKES SHORELINE EROSION - Michigan
WHAT CAUSES EROSION? Erosion is the wearing away of the shoreline by forces moving sand and soil from one area to another Waves, water levels, rain, wind, groundwater, frost and people all contribute to eroding shorelines WHAT ARE HIGH RISK EROSION AREAS? The Great Lakes shoreline is an actively eroding coast Some shorelines erode
What causes streambed erosion? - Queensland
What causes streambed erosion? What is bed erosion? Bed erosion, degradation or lowering, is a process by which the bed of the stream is eroded to a new lower level at a much faster rate than occurs naturally These bridge abutments were originally built at bed level Bed lowering can move in both an upstream direction (as
Erosion and Sedimentation on Construction Sites
erosion on the slope but will trap some of the sediment leaving that slope The RUSLE model estimates this sediment yield, as displayed in Table 1 Table 1 Effects of management practices on controlling erosion on a road bank Estimated sheet and rill erosion and sediment yield using RUSLE during a construction year in Nashville, TN1

The Agents of Erosion - Earth Science
Erosion and mass wasting appear to be similar processes but have distinctly different causes The movement of sediment by erosion requires mobile agents such a water, wind and ice That is, the sediment is transported by the movement of the agents USGS Mass wasting (commonly referred to as landslides) involves the transfer of rock
Resource Concerns Sheet, Rill and Wind Erosion
Soil erosion can be avoided by maintaining a protective cover on the soil and modifying the landscape to control runoff amounts and rates To avoid water erosion, include high residue, perennial, and sod crops in the cropping system, grow cover crops, manage crop residues, and shorten the length and steepness of slopes
