No abstract. From introduction: This paper considers the development of angled traveling screens and fixed and traveling louvers that can be used to divert fish to bypasses within power plant intake screenwells. Developmental work was done in three phases: 1) An extensive literature review and engineering design evaluation done to determine the effectiveness of previously evaluated facilities and to identify engineering considerations that would influence using angled screens and louvers in a power plant intake; 2) 4 yr lab physical model studies concluded that the angled screen was more cost-effective for the specific power plants under consideration; 3) Design criteria for effective application was established and the angled screen diversion system was incorporated into two power plant screenwells.
