Effect of various flow, sediment and geometrical parameters on partially or fully submerged deck scour

Abstract The effect of various parameters flow, sediment and geometric features the bridge on depth shape scour hole occurred underneath a deck model without pier was investigated by series experiments conducted in flume under partially fully submerged flow clear water conditions. were performed with factors such as approach depth, discharge, size, degree submergence, girder location depth. A total 112 for both experimental data showed that increased maximum affected more when compared to flow. It also noted directly structure opening height might significantly increase hole. Effect distance between single edge tested using three different it found increased, decreased moved where contraction area occurred.
