Generation of surface waves due to sudden movements at the sea bottom

Kırlangıç, Özgür Ulaş
A mathematical model is developed for investigating time dependent surface deformations of a hydrostatic water volume, when it is subjected to a sudden partial collapse or rise of the sea bottom. The model solves two-dimensional Navier-Stokes Equations on a vertical plane numerically by using Marker and Cell Method (MAC) for viscous and compressible fluid including all the nonlinear effects in the solution. For demonstration, a vertical motion was given to a section in a hypothetical reservoir bed within a short time period and the resulting velocity and pressure fields and the surface profile of the water body are obtained. Computational and physical aspects are discussed.
