Vertical slot ﬁshway Numerical simulations Two-dimensional over depth-averaged model Slot the optimization Hydraulic model Velocity ﬁeld a b s t r a c t Design of effective ﬁshways is becoming increasingly important. This paper focuses on the effect of the angle of deﬂection ( ) between small and large bafﬂes in a vertical slot ... Plate 21: Vertical slot fishway retrofitted to a small ... Vertical slot fishways The basic design of a vertical slot fishway is a rectangular channel partitioned by baffles into resting pools. When the water is flowing the fish swim from pool to pool through vertical slots that are orientated vertically. The advantage of this design is that passage is possible at a variety of water levels (Plate 21 ... Fishways | Department of Agriculture and Fisheries, Queensland

CONTROL OF TURBULENT FLOW IN VERTICAL SLOT FISHWAYS FOR ... Vertical slot fishways are commonly used and are very effective in ensuring unhindered passage of the species of large size fishes. The flows within these hydraulic structures are turbulent and present unsteady vortex dynamic in ... New designs for vertical slot th ... Hydraulics of Vertical-Slot Fishways: Nonuniform Profiles ... The performance of two particular designs of vertical slot fishways for two different slopes was studied in a wide range of discharges. Water depths were measured in almost the whole surface of pools.

The hydraulics of a vertical slot fishway: A case study on ... 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. The ﬁshway has a number of features that combine for a unique design. CONTROL OF TURBULENT FLOW IN VERTICAL SLOT FISHWAYS FOR 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).

A fish ladder, also known as a fishway, fish pass or fish steps, is a structure on or around ... The original design for a Denil fishway was developed in 1909 by a Belgian scientist, G. Denil; ... 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.
