Abstract: Scouring at a bridge is a problem that has always been a concern to engineers. The bed scours in alluvial rivers pose a threat to the stability and safety of foundations. Therefore, calculating the depth of scour around a bridge pier for different opening ratios is an important parameter in the design foundations of the bridge pier. In laboratory studies and field investigations, many investigators have suggested conditions for analyzing scour depth surrounding bridge piers in alluvial soils. Many studies have considered normal flow conditions around the bridge. In the present study, cylindrical piers of diameters 25mm, 40mm, 60mm, 75mm, and 90 mm are investigated for the experimental evaluation of scouring around piers. In the present experimental work, the depth of scouring is measured around the piers. It found that scour depth goes on increasing with an increase in pier diameter. As pier diameter increases, there is a decrease in the opening ratio and non-dimensional scour depth.

Key words: scour depth, bridge piers, opening ratios, pier diameter
