A CFD-based investigation of hydraulic regimes in overflow weir fishways
Overflow weir fishways represent a basic type of pool-and-weir fishway structure. To investigate its hydraulic characteristics, this study conducts numerical simulations to obtain the flow field in a typical pool chamber. A total of nine cases are designed by varying the inlet discharge and pool depth, and the flow pat...
