Scouring around different shapes of bridge pier

Abstract Scouring is a complex process dependent on several factors, and local scour more than general scour. This study was an attempt to predict round bridge piers based in the water stream. Three obstacle shapes were used – circular, round-nosed, elliptical as they are predominant hydraulic structures like piers. For each shape, depth measured around periphery for five gradually increasing discharges two types of bed material. The results analyzed relate them Lacey's equation estimate Models developed three common shapes, by which any particular shape can be predicted
