Investigation of Local Scour Hole Dimensions around Circular Bridge Piers under Steady State Conditions

The local scour around bridge piers is one of the main causes failures. In this study, hole dimensions circular were investigated under clear water conditions for various steady flow rates. experiments performed with four different pier diameters and seven rates by using uniform sediment a median diameter 1.63 mm geometric standard deviation 1.3. After each bathymetry was determined. New empirical equations to estimate length, width volume (V) are proposed experimental findings data available in literature. results also compared those calculated several given previous studies. Since there lack about dimensions, presented study useful researchers investigating process, have contributed few
