Abstract
A self-cleaning screen and method for screening water for hydraulic turbine intake diversions is disclosed. A check dam is established across a river on the downstream side of a side channel weir which is at a lower elevation than the dam. A fish transport trough is laterally spaced from the weir at a lower elevation and has an inlet upstream of the weir and an outlet downstream of the dam. A screen having a concave profile is connected between the weir and the trough to remove debris from water flowing over the weir. Water flowing through the screen enters a separate channel under the screen for diversion to a hydraulic turbine inlet water application. Intermittent surges of water over the weir flush debris off the edge of the screen into the trough to clean the screen.
