Spillway Designxls Better — Ogee

In a design spreadsheet, the is defined by the coordinates of its S-shaped profile, ensuring the water never loses contact with the concrete surface. The key governing equation for the downstream face is Hdcap H sub d is the design head and are constants based on the slope of the upstream face. Hdcap H sub d or a list of USBR constants for different upstream slopes?

The crest profile is typically divided into two sections: the upstream curve and the downstream profile. In a design spreadsheet, the is defined by

The design focuses on creating a profile that matches the lower nappe of a fully ventilated weir. : is discharge, is the discharge coefficient, Lecap L sub e is the effective length, and Hecap H sub e is the head over the crest. Discharge Coefficient (
