Abstract

This paper contains the results of an experimental study on head loss through angled screens for fish protection. A physical model on a scale of 1: 2 was conducted to assess the effect of the geometry, defined by the angle, bar shape and bar spacing on head loss for a range of flow velocities. The results indicate that head loss increases with increasing blockage ratio, angle to the screen plane and the approach flow velocity, as expected by literature. Furthermore the measured data was compared with estimated results of some selected literature approaches, where their conformance is discussed in the paper.
