Abstract: Vertical slot fishways are commonly used and are effective in ensuring unhindered passage of the species of large size fishes. Nerveless the species with small sizes have some difficulties to upstream migrate because the kinematic energy and the velocity are too large for them. One of strategies to answer at this ecohydraulic problem is to determine how the design of existing fishways might be affected by obstacles addition within the pool. This article presents a method to find the optimal cylinder location from numerical simulations of the flow in vertical slot fishway. The modification effect on the main hydraulics parameters of the flow is substantial and allows having a positive impact on biological efficiency of the device.
