Abstract

The construction of the pivot dam on the natural river course will have a great impact on the fish ecology, and the most direct impact is to block the migratory passage of fish. The fish crossing facilities can restore the migratory channels of the upstream and downstream, which not only increases the possibility of the fish crossing the dam to complete the migration and the life history, but also has positive ecological significance for other organisms. Therefore, the relevant parameters in fishway design should be reasonable to ensure that the fish can enter and leave the fishway and pass through the fishway smoothly. Based on the experience of many similar projects at home and abroad, and combined with hydraulic characteristic test, this paper elaborates the determination process of important parameters such as running water level; design flow rate and fishway baffle of a new junction, and verifies its rationality, which can provide a reference for similar projects.
