PDF | This paper presents the results of an experimental study on the hydraulics of vertical slot fishways. Seven designs, including some conventional designs, were tested. A conceptual uniform Hydraulics of Vertical-Slot Fishways: Nonuniform Profiles 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. New designs for vertical slot fishways - Canadian Journal This paper presents the results of an experimental study on 18 designs of vertical slot fishways. Based on these results, it appears that a width of 8 b 0 and a length of 10 b 0 for the pools, where b 0 is the slot width, are satisfactory, and minor variations can be made to these dimensions without affecting their satisfactory performance.

The larger the ..... control entrances, suggests that they were attracted to the greater flow from the experimental ... It creates a velocity shadow so fish can approach the entrance area.

Experimental approach to the hydraulics of vertical slot fishways. CONTROL OF TURBULENT FLOW IN VERTICAL SLOT … scale ¼ is used for this experimental study. This model has average characteristics of 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). EVALUATIONS OF PACIFIC LAMPREY SWIMMING BEHAVIOR … sections. We also compared results from the experimental flume to in-situ video observations of lamprey behavior within the serpentine weir sections of Bonneville Dam. We evaluated lamprey success rates and behavior in an experimental flume, which had a vertical slot structure similar in design to a serpentine weir at Bonneville Dam. This slot weir

INTRODUCTION TO FISHWAY DESIGN - MAFIADOC.COM SECTION 5 • FISHWAY HYDRAULICS Page 16 5.1 Vertical Slot Fishways A vertical slot fishway (Fig. 2.1) consists of a sloping (or stepped) rectangular channel which is partitioned into pools. Water flows down the channel from pool to pool through slots oriented vertically. Christos Katopodis - Academia.edu

The vertical slot fishways are hydraulic structures that allow the upstream migration of fishes through engineering constructions or natural obstructions in rivers. This type of pool fish pass is generally very effective in ensuring passage of the target species, particularly diadromous species. UMESC - Fish passage bibliography - Hydraulics of vertical ...

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.
