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. 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.

INNOVATIVE FISHWAYS MANIPULATING TURBULENCE IN THE ... There are two major hydraulic characteristics used in the design of vertical-slot fishways to optimize passage of small-bodied and large-bodied fish: i) the turbulence in the fishway pool and ii) the maximum water velocity in the slot between each pool.

and restore river connectivity. Fishways function as a means of passage around hydraulic barriers for ﬁsh migrat-ing both upstream and downstream (Clay, 1995; Katopodis and Williams, 2012). There is a diversity of ﬁshway designs including engineered structures (e.g., pool and weir, Denil, and vertical slot) as Science, Service, A Fish Ladder Types O – Due to minimum slot widths and flow depths, vertical slot ladders will not work for particularly low flows. NOAA FISHERIES SERVICE Vertical Slot Fish Ladders • Hydraulics of vertical slot fishways – As in pool and weir ladders, energy is dissipated from pool to Fish ladder - Wikipedia A fish ladder, also known as a fishway, fish pass or fish steps, is a structure on or around ... A vertical-slot fish passage is similar to a pool-and-weir system, except that each "dam" has a narrow slot in it near the channel wall. ...

Abstract. This paper presents a novel experiment for the correlation between the hydraulics and the swimming behavior of Schizothorax prenanti, a rare species of fish in southwest China, in passing a vertical slot fishway.
