Experimental approach to the hydraulics of vertical slot fishways

Experimental results in vertical slot fishways show that the vertical velocities are much smaller than the horizontal ones except in the vertical slot region and that the velocity field is quite uniform along the vertical direction (Puertas et al., 2004).Accordingly, a Vertical Slot Fishway: Evaluation of numerical model quality Vertical Slot Fishways (VSF) have shown a range of applications that are well documented. paper is a first approach on defining model qualities in respect to mesh size and simulation time properties. Numerous numerical investigations state that LES reproduces

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 8b 0 and a length of 10b 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.

Vertical Slot Fishway: Evaluation of numerical model quality Vertical slot fishways (VSF) are facilities to enable fish to migrate beyond (man built) obstructions such as dams or hydropower plants. VSF are rectangular channels separated into a sequence of pools by vertical walls. Vertical slots in these walls provide a migration corridor (Clay 1961; Rajaratnam et al. 1986).
