Physical Model Studies of the GCID Pumping Plant Fish Screen StructureAlternatives. Progress Report No. 1. 1:30 Scale Model Investigations: Alternative D

摘要

The Bureau of Reclamation constructed a positive barrier fish screen (alternativeD) physical model for GCID (Glen-Colusa Irrigation District) to evaluate, improve, and document the viability of the concept as a means to protect the fishery resource. The information included in this report is provided to the GCID Technical Advisory Group to assist in the evaluation of proposed screen alternatives and to provide design data for the selected alternative. The study results show the long flat plate screen concept can be designed to meet the listed objectives. A series of modifications to the screen design was identified and instituted through the model study to improve performance. Prior to completion of model testing, a final test was conducted to verify repeatability of the data.
