Abstract
In this paper, we study the problem of waves generated by subaerial landslides; a very complex problem involving granular physics, fluid mechanics and wave processes. Recently, a few studies (Bullard et al., 2019; Rauter et al., 2021) proposed a simplification of the generation stage, considering a water slide (i.e., an inviscid liquid with the same density as the reservoir fluid). In these studies, they concentrate on the prediction of the maximum wave amplitude after generation. In the present paper, we follow the same strategy of simplification, but this time, focus on the energetic transfer processes from the stage of generation, to the end of the main wave transformations.
