Spillway Designxls Better | Ogee

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

coordinates that define the spillway crest, ensuring that at the design head, the water remains in contact with the surface to prevent negative pressure and cavitation. numerical example calculated for a specific discharge rate and dam height? ogee spillway designxls better

The design of an centers on creating a shape that mimics the "lower nappe" of a freely falling water jet to ensure hydraulic efficiency and prevent cavitation. To perform these complex calculations effectively in a spreadsheet (like a "design.xls"), the process is typically broken down into determining the design head, calculating the crest profile, and defining the downstream curve. 1.
