Vertical slot fishways (VSF) are facilities to enable fish to migrate beyond (man built) obstructions such as dams or hydropower plants. VSF are rectangular channels separated into a sequence of pools by vertical walls. Vertical slots in these walls provide a migration corridor (Clay 1961; Rajaratnam et al. 1986). The sequence of Field and numerical assessment of turning pool hydraulics ... Vertical slot fishways are composed of regular pools connected in sequence forming linear ladders. Regular pools have been the subject of extensive study translating into a detailed understanding of their hydraulics, and the development of design standards ( Liu et al., 2006 , Puertas et al., 2004 , Rajaratnam et al., 1992 , Wu et al., 1999 ). Paired hydraulically distinct vertical-slot fishways ...
Fishways are used in various rivers throughout the Murray-Darling Basin to enable fish to bypass physical barriers such as weirs. This animation explains...
Hydraulics of Fishways | Engineers Australia 3. An overview of the hydraulics classification of fishway stuctures including rock ramp, vertical slot, fish lock and other fishways. 4. Presentation of recent collaborative field trials by the Department of Primary Industries and UNSW WRL and their immediate application to design standards. New designs for vertical slot fishways - Canadian Journal of ... 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.

Fishways have been developed to allow the upstream passage of fishes through dams.This paper presents a laboratory study, where a vertical slot fishway was built in a hydraulic flume and the behavior of two neotropical fish species (Leporinus reinhardti and Pimelodus maculatus) were analyzed.
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. Hydraulics of Vertical Slot Fishways | Journal of ... This paper presents the results of an experimental study on the hydraulics of vertical slot fishways. Seven designs, including some conventional designs, were tested. A conceptual uniform flow state has been defined for which a linear relation has been found between the dimensionless flow rate and relative flow depth.
