Abstract: An investigation has been made to predict the location of the inception point of the air entrainment over the stepped spillways by assuming the different configurations steps on the spillways as a kind of roughness. The physical model is constructed with a broad-crested weir, step heights of 25, 50, 100 mm, and Froude numbers ranging from 0. 795 to 8. 694. The configurations of steps are flat steps and pooled steps. A new relationship for predicting the location of the inception point is developed, applicable for slope of 30? stepped spillways. This relationship is similar to Chanson�s, but it is optimized for flat stepped and pooled stepped with a broad-crested weir
