First Powerhouse, Bonneville Dam, Columbia River, Oregon, Report 1, Proposed Trash Holding System: Hydraulic Model Investigation

Abstract

Potential changes to juvenile bypass system would significantly reduce the flow capacity of the existing ice and trash sluiceway, resulting in the sluiceway not being able to pass trash and ice from the forebay to the tailrace efficiently. Utilizing a 1:40-scale model of the Bonneville First Powerhouse, various possible trash boom location scenarios were evaluated. The trash boom would be used to collect and direct ice and trash to the Unit 0 sluiceway opening efficiency. The investigation involved velocity measurements along the trash boom to assist in determining the hydraulic loading, and several different types of floating debris were used to evaluate the effectiveness of various trash boom designs.
