| Abstract An experimental investigation on the problem of local scour downstream Ogee spillway is presented here by using two types of noncohesive bed material. The paper briefly explains the effect of hydraulic conditions of flow and sediment characteristics on depth and the extent of scour. The obtained results show that the depth and extent of scour affect greatly by the rate of the discharge and the depth of tail water. The size and shape of bed material particles plays an important role in characteristics of the occurred scour. The experimental data was used to develop two empirical relations to predict the depth and the extent of the scour downstream the Ogee spillway. Keywords: Scour, Ogee type Spillway, Hydraulics | ||
