Hydraulic Performance of Bridges, Efficiency of Earthen Spur Dikes in Mississippi
Properly constructed earthen spur dikes change the location of potential scour from near bridge abutments to the upstream end of the dikes where scour no longer endangers the bridge abutments. Spur dikes create more uniform flow velocities and reduce eddies near bridge abutments. The size of eddies appears to be related to the ratio of the side flow to the flow approaching the bridge. Overtopping of spur dikes by floodwaters causes them to become less effective. In Mississippi, spur dikes commonly increase backwater. (Author)
