An Ogee spillway design XLS is a pre-configured computational tool that automates the hydraulic and geometric calculations required for spillway construction. These spreadsheets typically use formulas derived from the or the U.S. Army Corps of Engineers (USACE) standards. Key features usually include: Discharge Coefficient Calculation ( ogee spillway designxls install

Before entering data, ensure the "Settings" or "Inputs" tab is set to your required unit system (SI/Metric or US Customary). Step-by-Step Design Procedure Using the XLS tool typically follows this logical flow: 1. Define Design Inputs You must provide the fundamental hydraulic parameters: Design Head ( Hdcap H sub d ): The maximum head for which the profile is shaped. Design Discharge ( ): The target flow rate. Crest Elevation: The vertical height of the spillway crest. Approach Depth ( ): The height from the upstream floor to the crest. 2. Calculate the Crest Profile
