Rajaratnam, N., C. Katopodis and N. McQuitty (1989). Hydraulics of culvert fishways. 2: Slotted-weir culvert fishways. Canadian Journal of Civil Engineering. 16:375-383.
This paper presents the results of an experimental study on the hydraulics of culvert fishways with a slotted-weir baffle system. Six designs with two baffle heights and three spacings were tested. A flow equation has been developed to predict the flow depth for any given discharge, diameter, and slope. The barrier velocity that would exist at the slot in the baffles has also been predicted in a general manner. This relatively simple slotted-weir baffle system has been found to match the performance of the more complicated but frequently used offset baffle system of similar dimensions.
