| 摘要： | The Bureau of Reclamation and the Contra Costa Water District (CCWD) have initiated planning and pre-design activities which will lead to the installation of fish screens at CCWD’s Rock Slough Diversion. Fish screens are required per Section 3406(b) of the Central Valley Project Improvement Act (CVPIA), and the Los Vaqueros Biological Opinion for Delta smelt. issued by the Fish and Wildlife Service in September 1993. Two separate physical models were used to evaluate designs for the Contra Costa Canal fish screen structure facility. One model was constructed for the purpose of evaluating approach flow conditions and velocity distributions along the length of the structure and to determine required baffling to produce a uniform velocity distribution. A second model was constructed to evaluate the proposed hydrorake system that will be installed at the facility to remove debris from the screens. |
