Background

According to the development of the hydropower industry in China, a large number of medium-low water head dams are built in succession, and the dam construction has great influence on aquatic organisms, particularly on the blocking influence on migratory fishes. The arrangement and structural design of fishways in the future are becoming the most popular research. The fishway is a building for restoring the connectivity of rivers and facilitating aquatic organisms to pass through a river-blocking barrier to trace or descend the river for migration. In the traditional fishway, the vertical seam type fishway has good adaptability to flow and water level change, and meanwhile, the high and low flow rates are distinct, so that a rest space can be provided for fishes, physical strength recovery is guaranteed, and the vertical seam type fishway is popular with fishway designers. However, the traditional vertical seam type fishway has a single structure, the flow velocity of the vertical seam for passing the fish is single, the fish passing effect is not ideal, and the impact force of water flow is too large due to too high upstream, so that the fish shoal cannot pass the upstream.
