Vertical slot fishway Water level a b s t r a c t This paper presents an overall assessment of the hydraulics of a vertical slot fishway, the Vianney-Legendre vertical slot fishway on the Richelieu River in Quebec, Canada, which has been shown to be successful for passing a variety of fish species, including lake sturgeon. Hydraulics of Fishways | Engineers Australia 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 ... 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. In the two general groups of designs, design 6 in the ...

several vertical slot fishways built in France. The velocity scale is 1/2 and the discharge scale is 1/32. The width of the slot is b = 0.075 m. The vertical slot fishway model consists of five pools, L = 0.75 m long and H = 0.55 m deep (Figure 1).

Keywords. design, fish ladder, flow rate, flow rates, hydraulics, pool, vertical slot MULTISPECIES FISH PASSAGE BEHAVIOUR IN A VERTICAL SLOT ... Although a number of multispecies fishways now exist in North America, evaluations of these fishways are lacking. We used a passive integrated transponder antenna array to quantify passage success and passage duration of fish using a vertical slot fishway (85 m in length, 2.65 m elevation rise, 12 regular pools and 2 turning basins) at a low ...

Fishway hydraulics, however, have been intensively studied only starting since the 1980's. Fishways have been classified into three main categories according to their hydraulic characteristics: pool-and-weir, vertical slot, and Denil … HEC-RAS Research Papers - Academia.edu

Hydraulics and swimming behavior of schizothorax prenanti ... 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. 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 ...
Even though vertical slot fishways are well studied, further hydraulic effects can be observed. In this context, the present paper investigates the hydraulics of vertical slot fishways and deals with the effect of downstream water levels on the hydraulic flow situation on vertical slot fishways.

Tuhtan, Mario Eckert,Filipe Romão, Maria Teresa Ferreira, Maarja Kruusmaa, Paulo Branco In Journal of Hydraulic Engineering Vertical slot fishways are subject to variations in discharge of either hydrological or operational origin, which result in non-uniform water depth profiles. Field and numerical assessment of turning pool hydraulics in ... conducted for turning pools in vertical slot fishways. Given the lack of existing hydraulic data accompanied by the comparatively low passage success rates there is cause for further study to evaluate and improve turning pool hydraulics, relative to fish passage. Here we characterize turning pool hydraulics of the Comparison between 2D and 3D Hydraulic Modelling Approaches ...
Fish ladder - Wikipedia Written reports of rough fishways date to 17th-century France, where bundles of branches were used to create steps in steep channels to bypass obstructions.
