Abstract
In a reservoir, a big wave sometimes is generated by huge inflow of sediments such as a landslide and debris flow, and causes serious damage to human beings. Therefore, it is very important to investigate the characteristics of waves in the reservoir due to inflow sediments. In this paper, a two-dimensional numerical simulation model based on shallow water equations integrated with the water depth is applied to some experimental results and Vaiont dam disaster in italy for waves generated by inflow sediments, and its characteristics are discussed.
