This study analyzed the influence of different test conditions and engineering measures on the distribution characteristics of multistage bifurcations based on the tail physical model of the Ganjiang River, and discussed the linkage responding law of multistage bifurcations. The results indicate that the distribution characteristics is influenced by discharge, branch mouth topography, position of the island head, entrance topography of branch and water surface slope at varying degrees. In addition, when an influence factor in a bifurcation is changed, the water diversion ratio in neighboring bifurcations will change, as well as other bifurcations, which is the linkage responding phenomenon.
