Prediction and Estimate of Run-Up and Breaking of Waves Generated by Landslides in Reservoirs
Accurate prediction of the climbing height and breaking of waves in front of the dam is crucial for engineering risk prevention and control.Therefore,this study assumes that the wave run-up process follows a nonlinear shallow water equation,and establishes a theoretical model for predicting the run-up height of nonlinear oscillatory waves,nonlinear transition waves,and quasi-solitary waves on slopes.The demonstration and verification found that the method proposed in this study has high accuracy and can simulate the run-up process of nonlinear transition waves and oscillatory waves on slopes.The maximum prediction error does not exceed 10%,and most er-rors are less than 5%.The correlation between Iribarren number and relative peak height introduced in this study can distinguish the breaking types of nonlinear oscillatory waves,nonlinear transition waves,and quasi solitary waves,but cannot distinguish the breaking of dissipated surge wave.This study can provide technical means for early warning of waves generated by landslide in the reservoir area.
