Abstract
This note presents the results of an experimental study on the hydraulics of pool and weir fishways. A simple weir-type flow analysis is found adequate to describe the plunging flow regime. A surface stream analysis is performed to predict the characteristics of the streaming flow. A parameter is developed to predict the transition from plunging to streaming flow.
