Vertical slot fishways are widely used and are generally very effective in ensuring fish passage. The appropriate design of a vertical slot fishway depends on an interplay between hydraulic and biological variables, since the hydrodynamic properties of the fishway must meet the requirements of the fish species for which it is intended. Design of Fish Passages & Ladders with HEC-RAS Although vertical slot fishways can be designed to pass a wide variety of fish species over a significant flow range, they are less passable for fish that tend to follow or cling to walls or jump over weirs. The pools of a vertical slot fishway are hydraulically complex and do not supply resting areas as tranquil as a pool and weir/orifice ladder.

A ‘flared-slot’ design is presently being applied to three new fishways on the lower Darling River. These fishways will be built on a 1:20 gradientThe vertical-slot fishways presently being designed and built for the Locks on the Murray River are world-class in functionality, passing a high diversity of...
Innovations in vertical slot fishway design - Finterest -… The vertical slot fishways built for locks 7, 8, 9 & 10 on the Murray River are world-class in functionality, passing a diversity of migratoryThe results show that refining the vertical slot design can improve fish passage performance, but further research is needed before design changes can be... Numerical 3D CFD simulation | vertical slot Hence, vertical slot passes are suitable for a wide range of species and also a wide range of water levels. Also less space is necessary in comparison with crossbar block ramps (Environment Agency 2010, DWA-M 509 2014).New designs for vertical slot fishways.

Evaluating vertical-slot fishway designs in terms of fish swimming capabilities - ScienceDirect
Vertical Slot Fishways (VSF) have shown a range of applications that are well documented. In 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 ... New tools, like numerical simulation ... An experimental study of turbulent flow in vertical slot 3.1 Turbulent flow in vertical slot fishways Fig. 2 shows the streamlines and velocities in the plane Z/b = 2 for four configurations of vertical slot fishways (slope I = 10 % and width B/b = 9, 7.66, 6.66 and 5.66) for a flow discharge Q = 23 L/s. For all the configurations, the flow in a pool is mainly composed of three important areas [6]: a Study on flow characteristics in vertical slot fishways 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
introduced new design concept: threshold & design values initiated QA process –biological monitoring is only required in principle, if design criteria are not complied with (reduced monitoring effort in standard projects/ locations) assessed new fishway structures, e.g. Round Vertical Slot Fishway, Bristle-type Fishway
