Rajaratnam, N., C. Katopodis and M. A. Fairbairn (1990). Hydraulics of culvert fishways 5: Alberta fish weirs and baffles. Canadian Journal of Civil Engineering. 17:1015-1021.
This paper presents the results of a laboratory study of the hydraulic performance of fish weirs and fish baffles used by Alberta Transportation for improving the fish-passing capacity of culverts. It was found that if the longitudinal spacing of the weirs is limited to 0.6 and 1.2 times the diameter of the culvert, their performance is comparable to that of the corresponding weir and slotted-weir baffle systems, with regard to the depth of pool between the baffles as well as the barrier velocity. On the other hand, the fish baffles did not perform as well as the fish weirs under the conditions tested.
