Abstract

This article focuses on the effect of frequency dispersion on the wave runup height and the characteristics of the surface waves reflected from the coastal slope. The calculations are performed within the framework of nonlinear dispersive and dispersionless shallow water models using the original boundary conditions on the movable water-land boundary. We consider the problem of solitary wave runup on flat coastal slopes with parameters close to the characteristics of one of the Kamchatka bays, for which the authors obtained probabilistic assessments of the tsunami hazard. The obtained results show that the maximum runup and amplitudes of the reflected waves are overestimated by the dispersionless model by 100%.
