Abstract:

A new numerical model, based on the linear theory of elasticity and Marshs approximation of the Hankel transform, has been developed and used to model the excitation and propagation of interface waves in shallow-water sea-beds. Using realistic material parameters, the geometry and frequency-dependent propagation characteristics are analyzed and synthetic seismograms are produced. Basic properties of interface waves are discussed, and methods for direct evaluation of sea-bed properties from experimental results are proposed. Author
