Bridge scour is the removal of sediment such as sand and gravel from around bridge abutments or piers. Hydrodynamic scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure. [1] In the United States, bridge scour is one of the three main causes of bridge failure (the
Hydrodynamic scour is the removal of sediment such as silt, sand and gravel from around the base of obstructions to the flow in the sea, rivers and canals. Scour, caused by fast flowing water, can carve out scour holes, compromising the integrity of a structure.
Hydrodynamic scour, the removal of sediment such as sand and silt from around an object by water flow Bridge scour, erosion of soil around at the base of a bridge pier or abutments via the flow of air, ice, or water; Tidal scour, erosion of substrate via tidal flow; Ice scour or ice gouge, a drifting ice feature that scrapes the seabed
Tidal scour can be determined by looking at the change in bathymetry over time. Bathymetry of tidal channels is determined using multi-beam sonar or LiDAR. By comparing cross-sections of channel bathymetry over several years and at various distances in the tidal channel, the amount of tidal scour can be quantified. [2] [better source needed] [4 ...

Cleaning with a scouring pad. Toroidal scouring pad made of plastic wires, thus less aggressive to non-stick surfaces. A scouring pad or scourer is a small pad of metal or plastic mesh used for scouring a surface.
Cross-bedding and scour in a fine sandstone (Logan Formation, Mississippian, Jackson County, Ohio) A teepee structure in modern halite deposits along the western shore of the Dead Sea, Israel. These structures are within sedimentary bedding and can help with the interpretation of depositional environment and paleocurrent directions. They are ...
Scouring is an essential pre-treatment for the subsequent finishing stages that include bleaching, dyeing, and printing. [5] Raw and unfinished textiles contain a significant amount of impurities, both natural and foreign.
