Vertical slot fishways are hydraulic structures which allow the upstream migration of fish through obstructions in rivers.An effective vertical slot fishway must allow fish to enter, pass through, and exit safely with minimum cost to the fish in terms of time and energy.
A 3D numerical model using the re-normalized group (RNG) k-ϵ turbulent closure was applied to study the hydraulic characteristics of a fishway and their dependence on the shape of the baffles, bed slope and water level difference between two adjacent pools. Topologies and measurements of turbulent flow in vertical ... An experimental study was undertaken to characterize the turbulent flow for various configurations of vertical slot fishways and to determine how they might be modified to facilitate the passage of small species. Investigating innovations in vertical slot fishway design ... Key words: vertical slot, fishway, fish passage, innovation, Native Fish Strategy A major goal of the Murray Darling Basin Commission’s (MDBC) Native Fish Strategy is restoring fish passage, and one of the most successful mechanisms of doing this is to construct vertical-slot fishways. Field and numerical assessment of turning pool hydraulics in ...
Experimental Approach to the Hydraulics of Vertical Slot Fishways ...
River fishways are hydraulic structures enabling fish to overcome stream obstructions (for instance, dams in hydroelectric power plants). This paper presents a combination of mathematical modelling and optimal control theory in order to improve the optimal shape design of a fishway. Numerical and physical model study of a vertical slot fishway ... Abstract. This paper presents the results of an experimental and numerical study of a vertical slot fishway (VSF). A 2-D depth-averaged shallow water numerical model PCFLOW2D coupled with three different turbulent models (constant eddy viscosity, Smagorinsky and k - ε) was used.
