Abstract: Waves generated in a reservoir by a landslide are modeled by injecting an instantaneous point source of fluid through the bottom of a reservoir of infinite extent. This assumes that times are large relative to the duration time of the landslide and that distances are large relative to a characteristic horizontal dimension of the volume of water displaced by the slide material. Solutions are obtained for two-dimensional and axisymmetric problems, and the characteristics of each are discussed. Since the solutions assume a constant reservoir depth, and since maximum wave amplitudes always occur along shorelines of sloping beaches, it is suggested that these solutions may be of most use for providing boundary conditions for models of wave runup on sloping beaches. A comparison with experimental results is made, and agreement between the calculated and measured results is found to be good.
