  In this work we study the generation of water waves by an underwater sliding
mass. The wave dynamics are assumed to fell into the shallow water regime.
However, the characteristic wavelength of the free surface motion is generally
smaller than in geophysically generated tsunamis. Thus, dispersive effects need
to be taken into account. In the present study the fluid layer is modeled by
the Peregrine system modified appropriately and written in conservative
variables. The landslide is assumed to be a quasi-deformable body of mass whose
trajectory is completely determined by its barycenter motion. A differential
equation modeling the landslide motion along a curvilinear bottom is obtained
by projecting all the forces acting on the submerged body onto a local moving
coordinate system. One of the main novelties of our approach consists in taking
into account curvature effects of the sea bed.
