摘要

This paper summarizes the design equations for local scour depth around bridge abutments as proposed by different investigators, and also the different factors, affecting the scour depth. Methods for the estimation of local scour depth based on dimensional analysis are also presented. The design methods based on empirical relations such as flow depth, flow intensity, sediment characteristics, abutments shape and size, alignment, and approach channel geometry are also discussed. Since clear-water scour is the maximum scour depth, the equation for clear-water scour is recommended for the computation of local scour depth around bridge abutments for uniformly and non- uniformly graded sediments.
