Abstract

Comparison of local scour depths at bridge abutments computed using different equations yields a large variation in predicted values. To consolidate the fragmented results of previous investigations and assemble the most comprehensive data set possible, reported laboratory measurements of local scour at the end of an obstruction protruding from the side of an open channel of rectangular cross section were compiled from several sources. Regression analysis of these data was used to develop an equation that predicts maximum relative depth of local scour at bridge abutments for both clear-water and live-bed scour conditions.
