New designs for vertical slot fishways - Canadian Journal ... This paper presents the results of an experimental study on 18 designs of vertical slot fishways. Based on these results, it appears that a width of 8b 0 and a length of 10b 0 for the pools, where b 0 is the slot width, are satisfactory, and minor variations can be made to these dimensions without affecting their satisfactory performance. Hydraulics of Vertical-Slot Fishways: Nonuniform Profiles ... Vertical-slot fishways (VSFs) are hydraulic structures which allow fish to swim around obstacles in rivers. These structures are subject to variations in discharge of either hydrological or operational origin, which result in nonuniform water depth profiles. Topologies and measurements of turbulent flow in vertical ...
the same from top to bottom. The main advantage of the vertical slot fishway is in its ability to handle large variations in water levels. Usually the difference between water levels in successive pools is 300 mm for adult salmon and 200 mm for adult freshwater fish. Vertical slot fishways usually have a slope of 10%.

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.
