The proposed Longweizhou junction is a low-head hydro-junction project that focuses on navigation, flood control, water resources, and protection of the aquatic ecological environment. There are two continuous bends upstream and downstream of the dam site, and the straight section where the dam site is located is also short, so the river boundary conditions are not conducive to smooth flood discharge after the project. To demonstrate and optimize the general layout of the proposed hydro-junction, an integrated hydraulic-physical model with a scale of 1∶80 was adopted. On the basis of hydrodynamic similarity verification, a detailed experimental study was conducted on the discharge capacity of the hydro-junction, revealing the characteristics of flow velocity distribution and flow distribution in the original design scheme under typical flood conditions, clarifying the shortcomings of the original scheme and corresponding optimization ideas, putting forward the measure of cutting the side beach to improve discharge capacity. The optimized scheme test verified that the discharge capacity could meet the design requirements. The research results may serve as reference for the design of this project and other similar projects.
