Scour is the erosion of waterway soils and sediment that support bridge foundations. Soil is loosened from bridge supports and abutments that fortify each end of the bridge. One of the biggest causes of bridge failure, next to human failure, is scour.
This category is for sites about scour relating to bridge failure. Sites detailing the events and/or causes of specific bridges should be placed in their respective categories or in the main category if no sub category exists.
