INNOVATIVE FISHWAYS MANIPULATING TURBULENCE IN …
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 ...
