2.2 Scaling laws and vertical slot fishway model This vertical slot fishways is composed by 16 pools, figure 1. The measurements have been performed in the second pool of the fishpass.The design of vertical slot fishways has progressed thanks to the reduced model studies, and to empirical feedback on the constructed facilities.

Implications of Fish Behavior for Vertical Slot Fishways Design The goal of the present study is to analyze fish swimming behavior in these artificial environments and to explore its implications in the development of new fishway designs. To this end, a set of experiments has been conducted in an indoor full-scale vertical slot fishway model with different cyprinid and salmonid species. How a vertical-slot fishway works - YouTube This animation explains the conceptual layout and use of a vertical-slot fishway. For more information on fishways, visit our website www.mdba.gov.au Category INTRODUCTION TO FISHWAY DESIGN - eem.wra.gov.tw the same from top to bottom. The main advantage of the vertical slot fishway is in its ability to handle large variations in water levels. Usually the difference between water levels in successive pools is 300 mm for adult salmon and 200 mm for adult freshwater fish. Vertical slot fishways usually have a slope of 10%.

VERTICAL SLOT FISHWAY DESIGN The upper part of the VSF at HPP Blanca is a 2.2 m wide channel with longitudinal slope S0 = 1.67% and consists of 24 pools of length L = 3.0 m and slot width b0 = 0.59 m (Josipovič and Ciuha, 2009). The numerical and physical models of the VSF consisted of 5 pools with L = 3.0 m, a 6.0 m long inlet

Many fishways used in Australia are based on designs used for salmon and trout in the Northern Hemisphere. These fishways are ineffective for native fish species as they are too steep, too turbulent and cease to function during Qld's …
However, this configuration provided greater energy dissipation and reduction of velocities by up to 27%. Thus, modifications in nonstandard vertical slot fishways can be useful in future design or rehabilitation of existing structures in order to provide velocities and turbulence more friendly for a higher number of fish species.
