Removal of soil or fill material by the flow of floodwaters. The term is frequently used to describe storm-induced, localized conical erosion around pilings and other foundation supports where the obstruction of flow increases turbulence. See Erosion.
Erosion caused by flowing water; a shallow, fast-flowing, gravel-bottomed stretch of river.
erosion due to bottom currents
removal of sand or earth from the bottom or banks of a river by the erosive action of flowing water. Erosion of a concrete surface, exposing the aggregate. The action of a flowing liquid as it lifts and carries away the material on the sides or bottom of a waterway, conduit, or pipeline. The enlargement of a flow section of a waterway through the action of the fluid in motion carrying away the material composing the boundary.
A bank of mud or sand caused by water flow.
Erosion of the seabed caused by the action of waves and currents.
Erosion of streambed or bank material due to flowing water; often considered as being localized (see local scour, contraction scour, total scour).
erosion of channel beds and banks by streamflow.
removal of gravel or other material by moving water.
The erosion of a material by the action of flowing water.
The clearing and digging action of flowing air or water, especially the downward erosion caused by stream water in removing material (e.g., soil, rocks) from a channel bed or bank or around in-channel structures.
the removal of soil in the bed of a stream by a strong current
The erosive action of running water in streams, which excavates and carries away material from the bed and banks. Scour may occur in both earth and solid rock material.
process of water eroding material through high velocities in conjunction with moving sediment
Removal of sediment from the streambed by flowing water.
The result of erosive action of running water, primarily in streams, excavating and carrying away material from the bed and banks. Wearing away by abrasive action.
