Detailed design guide on fishway passage Fishway passage ladder fish migration water intake structure.Fishways have been classified into three main categories according totheir hydraulic characteristics: pool-and-weir, vertical slot, and Denil fishways.
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
INNOVATIVE FISHWAYS – MANIPULATING TURBULENCE IN ... or improving, the present functionality of the new vertical-slot fishways on the Murray River. 1.2 Vertical-slot fishway design . There are two major hydraulic characteristics used in the design of vertical-slot fishways to optimize passage of small-bodied and large-bodied fish: i) the ...
Designing Fishways - Fishways aren't one-size-fits-all, and designing a fish ladder takes some planning, depending on the location and species.Fish using a vertical slot fishway are guided upstream by a narrow passage that winds around the barrier; the water flow is constant and the fish...
