Sediment deposition and erosion processes - Coastal Wiki

Deposition and erosion are the two basic processes inherent to the movement of sedimentary particles in estuaries. As these processes determine the advective sediment load, understanding their mechanics is essential for load prediction. To begin with prevalent classifications related to particle diameter are summarized on a comparative basis.

Sedimentation and Erosion | The Caribbean Environment ...

Sedimentation and Erosion. Sediments are material of varying size of mineral and organic origin. Erosion is the process of carrying away or displacement of sediment by the action of wind, water, gravity, or ice (Smith & Smith 1998). The process of deposition of sediment from a state of suspension or solution in a fluid is called sedimentation ...

Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion . Gravity and mass wasting processes (see Chapter 10, Mass Wasting ) move rocks and sediment to new locations.

Sedimentation is the process in which particulate matter carried from its point of origin by either natural or human-enhanced processes is deposited elsewhere on land surfaces or in waterbodies. Sediment is a natural product of stream erosion; however, the sediment load may be increased by human practices.
