Abstract

Theoretical formulation describing the wave generation by a slender solid landslide is presented. The slide motion is coupled with the surface wave dynamics and both the fluid viscous (lubricative) resistance and the solid friction are considered.

Numerical results are obtained for a cosine function shape slide. Numerical results show clearly the importance of the dynamic nonlinear coupling. The effects of lubricative resistance, solid friction, initial landslide speed and the slide height are discussed.
