Hydraulics of vertical slot fishways

Field and numerical assessment of turning pool hydraulics in ... conducted for turning pools in vertical slot fishways. Given the lack of existing hydraulic data accompanied by the comparatively low passage success rates there is cause for further study to evaluate and improve turning pool hydraulics, relative to fish passage. Here we characterize turning pool hydraulics of the Comparison between 2D and 3D Hydraulic Modelling Approaches ...

This paper compares the use of one-dimensional (1-D) and three-dimensional (3-D) numerical models to simulate the flow of a vertical-slot fishway. Beg_Abstract

The vertical slot shway, hereinafter referred to as VSF, is an engineered structure. Variations of this design are commonly used around the world.Fishway hydrodynamics were investigated for Scenarios 1–5 using CFD modelling to identify the effective regular pool dimen-sions.

Fishways come in a range of forms including pool types (e.g. vertical slot), denil fishways, and rock ramp fishways. The vertical-slot fishway consists of rectangular channels with sloping or stepped floors that are divided into several pools (Alvarez-Vázquez, Martínez et al. 2007).
