Maximum depth of scour by impinging circular turbulent jet

In this paper result of experiments on scour due to impinging circular jet is presented. The effect of parameters like: drop height, jet diameter, jet velocity and tail water depth on maximum depth of scour was investigated. It was found that by increasing jet velocity and drop height, depth of scour increases. While increasing tail water depth decreases the depth of scour. A new equation for prediction of maximum depth of scour is introduced
