Abstract

The water flow characteristics in a fishway largely depend on the geometric shape of the partition. This study is the first to compare two classic fishway forms and study their hydraulic characteristics using CFD method. This study was conducted in a water tank with a slope of 10%, a length of 43.6m, and a width of 1.5m. Set up a rest area for every 10 baffles. The simulation results show that on the one hand, the vertical-slot fishway has better energy dissipation effect and more significant flow velocity reduction, and on the other hand, the Daniel fishway has a larger rest area at the bottom.
