The design of an is fundamentally based on the shape of the lower nappe of a freely falling water jet over a sharp-crested weir. An efficient design ensures that the water profile remains in contact with the spillway surface to avoid sub-atmospheric pressures and cavitation. 1. Discharge Calculation
