Description: Technical report
The U.S. Army Corps of Engineers, Walla Walla District (NWW), requested that the U.S. Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory (ERDC-CHL) model the flow conditions of McNary Dam forebay. The different flows are produced by various powerhouse/spillbay operating conditions for certain river discharges. The flow conditions, powerhouse operation schedule, and spillbay opening geometry were provided by NWW. This report contains a description of the geometry, meshing, and the flow conditions. The report also describes flow solutions obtained using the commercial flow code Fluent. Fifteen river discharge/powerhouse/spillbay operations were included in the analysis. Figures of the flow velocity, acceleration, and strain rate near each powerhouse unit and spillbay have been provided to NWW electronically.
