Hydraulics of the Vianney‐Legendre vertical slot fishway Hydraulics of the Vianney‐Legendre vertical slot fishway near SO QbSt. Ours, Quebec Adam Marrinerand Dr. David Zhu Department of Civil and Environmental Engggineering University of Alberta Dr. Steve Cooke, PhD New designs for vertical slot fishways. ... Applications of Computational Fluid Dynamics in The Design To aid in the design of vertical slot fishways, a three-dimensional numerical model was used to simulate the flow for different geometric configurations. An existing vertical slot fishway with nonstandard dimensions was initially modeled and validated. This geometry was used as a reference design.

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 How a vertical-slot fishway works - YouTube Aug 07, 2012 · This animation explains the conceptual layout and use of a vertical-slot fishway.

To aid in the design of vertical slot fishways, a three-dimensional numerical model was used to simulate the flow for different geometric configurations. An existing vertical slot fishway with nonstandard dimensions was initially modeled and validated. This geometry was used as a reference design. 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. Hybrid Investigation on the Hydraulic Performance of a New ...
Findings: The experiments yielded four major findings that are likely to lead to reduced cost and improved performance of fishways throughout the Basin: The baffle in the vertical-slot design has significant potential to improve fish passage. Turbulence in the fishway pool may be more limiting for the passage of small fish than the high water velocity in the slot of the vertical-slot baffle.
