Evaluation of selected equations for predicting scour at downstream of ski-jump spillway using laboratory and field data

► Scour depth prediction equations cannot be generalized for all ranges of total head and discharge. ► The observation on the suitability of scour depth prediction equations is not similar for laboratory and field results. ► Prediction using these equations is better for field data than experimental data. ► Requires further field investigations to ascertain the generality of Incyth equation for scour depth prediction.
