Bridge examination begins by office investigation. The history of the bridge and any previous scour related problems should be noted. Once a bridge is recognized as a potential scour bridge, it will proceed to further evaluation including field review, scour vulnerability analysis and prioritizing.
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.

An analysis of the technical documentation regarding the surveys of the bridge over time showed a lowering of the river bottom, next to the pillar that would collapse, of approximately 11.5 meters in the period from 1913 to 1982, and of 1.5 meters between 1982 and 1989.
The single greatest cause of failure in Washington has been flooding, frequently associated with severe storms, which then results in destructive bridge scour. [1] [2] [3] According to University of Washington meteorologist Cliff Mass, Western Washington is "particularly vulnerable to such bridge losses, with long floating bridges and the powerful winds associated with our terrain and incoming ...
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
