Experimental approach to the hydraulics of vertical slot fishways

Fishway and Ladder Design. Fishways and ladders provide migrating fish with upstream passage around or through fish passage barriers.Therefore, the engineer should perform separate calculations of composite flow profiles due to the complex nature of the hydraulic structures...

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. Reynolds shear-stress and velocity: positive biological ... The aim of this study was to understand the influence of three hydraulic parameters, namely Reynolds shear-stress, velocity fluctuation and mean velocity, on two neotropical fish species within a vertical slot fish ladder. A vertical slot model was built in a PLOS ONE: Pool-Type Fishways: Two Different Morpho ... Fish are particularly sensitive to connectivity loss as their ability to reach spawning grounds is seriously affected. The most common way to circumvent a barrier to longitudinal connectivity, and to mitigate its impacts, is to implement a fish passage

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.

Swimming activity and energetic costs of adult lake sturgeon… Fishways are increasingly being installed at these barriers and represent one solution to facilitate upstream passage of migrating fish, requiringThis study was conducted at the Vianney-Legendre Fishway, a vertical slot fishway located on the Richelieu River adjacent to the St Ours dam (45°...

"Considering Non-Salmonid Fish in Fishway Hydraulics" by R ... The chute can be inclined to slopes 0-30% and it can be fitted with different kinds of baffles and vanes. The scale model was constructed originally to improve the hydraulic conditions of the Poyry fishway in the River Siikajoki. Later it has been used in improving other fishways and in studying hydraulics of vertical slot and Denil fishways.
