Outline
The vertical slit fishway has the capacity to better cope with the fluctuation of water level in both upper and lower sections and favorable water flow conditions. Three schemes were designed for the shape of the fishway tank chamber of a certain project fishway. The physical models verified with a 1∶5 scales were used to investigate the impact of the tank chamber's structure on the flow pattern, maximum flow velocity, and hydraulic properties of mainstream region under different size and type of baffle and guide plates. This was done through numerical simulation calculation. They performed a test of the physical model on the optimal shape with scale of 1∶5. The physical model of the overall with scale 1∶20 was used to analyze the maximum velocity along the water depth and the vertical slit, and the diversion flow of the fishway under different water depth conditions was proposed, providing reference and reference for similar projects.
