Bridge scour - Wikipedia
Hydraulic Engineering Circular Manual No. 18 (HEC-18) was published by the FHWA, and includes several techniques of estimating scour depth. The empirical scour equations for live-bed scour, clear-water scour, and local scour at piers and abutments are shown in the Chapter 5 – General Scour section. The total scour depth is determined by adding three scour components which includes the long-term aggradation and degradation of the river bed, general scour at the …
