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 ... New designs for vertical slot fishways - CORE New designs for vertical slot fishways .

Vertical Slot Fishway: Evaluation of numerical model quality Currently, there is a need to consider site-specific conditions and develop optimal designs for vertical slot fishways. In Europe, this is in part due to the European Water Framework Directive (WFD 2000), which states ... Plate 21: Vertical slot fishway retrofitted to a small power plant.

The characteristics of the flow in vertical slot fishways depend mainly on the specific pool design, i.e., the geometry of the pool. This paper presents the results of a study on sixteen different designs of vertical slot fishways with two different slopes.

Evaluating vertical-slot fishway designs in terms of fish swimming capabilities. ... Vertical-slot fishways show basic bidimensional flow and dissipate kinetic energy in a different way, through “recirculation” flow. It would thus be of interest to estimate maximum acceptable power dissipation values specifically for vertical-slot fishways. Numerical and physical model study of a vertical slot fishway VERTICAL SLOT FISHWAY DESIGN The upper part of the VSF at HPP Blanca is a 2.2 m wide channel with longitudinal slope S0 = 1.67% and consists of 24 pools of length L = 3.0 m and slot width b0 = 0.59 m (Josipovič and Ciuha, 2009). The numerical and physical models of the VSF consisted of 5 pools with L = 3.0 m, a 6.0 m long inlet Influence of pool geometry on the biological efficiency of ...
