Abstract: Utilizing the experimental system for three-dimensional diffuse rock landslide surges in shallow water areas of bends under moving water conditions, this study investigates the fundamental patterns of surge climbing under the influence of hydrodynamic forces and the method to determine the maximum climb. Based on the data observed from the physical model experiments, characteristics values of climbing were calculated. The effects of water flow velocity, river depth, landslide volume, and landslide inclination angle on climbing were analyzed. Through multivariate nonlinear regression analysis and least squares analysis, the decay formulas for surge climbing along the opposite bank and the same bank under moving water conditions were obtained, respectively, and compared with the for surge climbing attenuation in diffuse rock landslides under static water conditions. Using dimensionless and multivariate regression analysis methods, a formula for calculating the maximum climb height under moving water conditions was given, and the calculation results were compared and verified with the actual measurement data of surge climbing in the Xintan landslide on the Yangtze River. The two results are relatively close.
