Abstract

This paper presents the results of an experimental study on the hydraulics of vertical slot fishways. Seven designs, including some conventional designs, were tested. A conceptual uniform flow state has been defined for which a linear relation has been found between the dimensionless flow rate and relative flow depth. Non‐uniform flow of the M1 and M2 types has been analyzed using the Bakhmeteff‐Chow method. Some observations have also been made on the velocity profiles at the slot and circulation patterns in the pools.
