Vertical-slot fishway is widely used in different shape of fish-way due to the adaptability to water level amplitude, the hydraulic characteristics of the vertical-slot fish-way of different scale has been extensively researched by researcher domestic and overseas, the energy dissipation mechanism and hydraulic characteristics of the fish-way in different scale under different inflow has been ... INTRODUCTION TO FISHWAY DESIGN - eem.wra.gov.tw Fish move through Denil fishways faster than through vertical slot or weir fishways. In fishway channels, fish transport relies on water velocities not exceeding the swimming abilities of the migrating species. Swimming ability varies with species, size, as well as water temperature,oxygen, pH, and salinity. Fishway Optimization Revisited | Springer for Research ... River fishways are hydraulic structures enabling fish to overcome stream obstructions (for instance, dams in hydroelectric power plants). This paper presents a combination of mathematical modelling and optimal control theory in order to improve the optimal shape design of a fishway.

This paper presents the results of an experimental and numerical study of a vertical slot fishway (VSF). A 2-D depth-averaged shallow water numerical model PCFLOW2D coupled with three different turbulent models (constant eddy viscosity, Smagorinsky and k - ε) was used.
