Estimation of potential bridge scour at bridges on state routes in South Dakota, 2003-07
Ryan F. Thompson, Ryan L. Fosness
2008, Scientific Investigations Report 2008-5161
Flowing water can erode (scour) soils and cause structural failure of a bridge by exposing or undermining bridge foundations (abutments and piers). A rapid scour-estimation technique, known as the level-1.5 method and developed by the U.S. Geological Survey, was used to evaluate potential scour at bridges in South Dakota in...
