Abstract: Fish passage in water conservancy projects is an important means of improving river connectivity, and reducing the impact on the ecological environment. Simulating natural fish passage, which aims at the purpose of the river ecological corridor by the means of ecological optimization on the structure and section type based on the traditional fish passage, is promoted and applied in recent years gradually. At the same time, the hydraulic research related to the simulating natural fish passage has made great progress. In this paper, we firstly collected and summarized the research experience of the domestic and foreign typical fish passage, analyzed the structural characteristics and requirements of the key factor ,which effected the fish pass through, discussed the hydraulic problems involved , Summed up the determination method and interaction rules of the hydraulic essential factor of the simulating natural fish passage, then Provided a reference for the design and research of simulating natural passage.
