Computational Model of Lower Monumental Forebay

摘要

The purpose of this study was to determine a course of action that would lead to improved juvenile fish passage at Lower Monumental Dam, a U.S. Army Corps of Engineers operated dam located on the Lower Snake River in Washington. A three-dimensional numerical model of the forebay approaching the dam and including the structures was constructed. Flow conditions with existing project configurations, followed by a series of configurations using a removable spillway weir and a behavioral guidance system, were simulated. The results were then evaluated to determine the effectiveness of the various designs. The results generated by the ADaptive Hydraulic computer model were then used for the numerical fish surrogate analysis of Lower Monumental Dam.
