Abstract

he propagation characteristics and parameter sensitivity of the landslide induced impulse wave in practical channel type reservoirs are investigated in this study. The two-dimensional Saint-Venant equation and dry-wet boundary treatment method are used to simulate the wave generation and propagation processes in real reservoirs. In order to better reproduce the initial wave, a matching technique of initial wave between nearfield and far field simulation is implemented, while the nearfield wave generation processes are simulated based on full Naiver-Stokes equation. A real landslide induced impulse wave event is simulated with this technique and the propagation characteristics and parameter sensitivity are investigated. The simulation results and comparison between different cases indicate that the longitudinal shape of the channel-type reservoir is a crucial factor for propagation. Classical engineering methods which ignore this factor might produce improper estimation of the max wave height.
