data, three equations were developed for prediction of scour depth downstream of
stepped spillways. From these equations, one can predict the scour depth. It was
found that the scour depth downstream of simple gabion stepped spillway is greater
than the scour depth for pooled stepped spillway. This is because the scour depth is
directly proportional to the kinetic energy at the downstream end of the spillway.
The kinetic energy at the end of simple stepped spillway is larger than the other
because there is less energy dissipation through this structure as compared to other
types of stepped spillways. A procedure for designing a gabion stepped spillway is
presented.
