Modelling surface waves generated by a moving landslide with allowance for vertical flow structure

Simulation of surface waves generated by an underwater landslide in a bounded reservoir

“…Thus, the use of the shallow water model of the first approximation leads to overestimation of the maximal splashing onto the shores of a deep bounded reservoir and requires taking into account the dispersive effects, in order to obtain a more accurate estimate. In this context, we plan to undertake a multiparametric study of surface waves generated by a landslide within nonlinear-dispersive models of wave hydrodynamics [3,7,8,16].…”

“…Some attempts at experimental study of surface waves generated in the motion of a rigid landslide model over a flat underwater slope have been undertaken recently [6,[9][10][11]20]. A series of papers considered numerical simulations of such problems (see, e.g., [3,9,16,19,20]) using the law describing the motion of a rigid landslide over a flat slope [12,15,20].…”

Simulation of surface waves generated by an underwater landslide moving over an uneven slope

“…The comparison was done for the simplest case when the bottom relief was a uniform slope passing into a flat bottom segment. The conclusion made by the authors of the papers mentioned here [2,3,6,19] was that in some particular range of the parameters of the problem, a sufficiently adequate description of the wave modes can be obtained using the simplest shallow water models, whereas a more detailed study requires the involvement of nonlinear-dispersive shallow water models taking into account the non-hydrostatic pressure and, which is the same, taking into account the contribution of the vertical flows of the liquid.…”
