A diagram showing how scour holes are formed. 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.
Bridge twisted and collapsed over State Route 49 while under construction. The expressway and the bridge itself were closed to the public at the time. 1 killed, 9 injured [54] Total collapse Bridge collapsed as workers were screeding a concrete surface on the bridge. The machine had made it to the bridge's midspan before the entire bridge ...
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
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.

Examples of this hydrological process can be found globally. [2] [better source needed] [3] [4] Two locations in the United States where tidal scour is the predominant shaping force is the San Francisco Bay and the Elkhorn Slough. [2] [better source needed] [5] [6] Tidal force can also contribute to bridge scour. [2] [better source needed]
Bridges may collapse due to bridge scour around one or more bridge abutments or piers. In 2004, the remnants of Hurricane Frances , and then Hurricane Ivan , caused a large number of washouts in western North Carolina and other parts of the southern Appalachian Mountains , closing some roads for days and parts of the Blue Ridge Parkway for months.
Some examples of marine structures include ships, offshore platforms, moorings, pipelines, cables, wharves, bridges, tunnels, breakwaters and docks. Marine construction may require diving work, but professional diving is expensive and dangerous, and may involve relatively high risk, and the types of tools and equipment that can both function ...
