Abstract : Dams and diversion dams are considered as obstacles to prevent the migration of fish along the river. The vertical
opening fishway is one of the types of fishway that enables the migration of fish upstream of the dam. Speed, water depth
and turbulence are effective parameters in fish swimming. In this study, the governing equations of shallow waters were
solved in three-dimensional mode in the fish passage of the vertical opening type of Ramhormoz diversion dam using
suitable turbulence models to calculate the flow and turbulence pattern. The speeds obtained from the numerical solution are
very similar to the laboratory data. In the vertical opening design under the angle of 90 degrees to the flow direction, the fish
having the maximum power of releasing 2.56 W of energy, has the power to overcome 2.25 W of energy and is able to climb
the way of the fish. The maximum speed of the flow in the opening in this case is about 1.7 meters per second.
