OMAE2009-80104 TRANSFORMATION OF MONO-AND MULTI-CHROMATIC WATER WAVES PROPAGATING FROM A QUASI-DEEPWATER TO A SHALLOW WATER REGION

Abstract

ABSTRACT A vertically integrated 3D numerical model that uses the concept of depth average velocity distribution with enhanced dispersion characteristics investigates the propagation and transformation of mono-and multi-chromatic waves from a quasi-deep region to shallow water region. A finite difference method has been employed for the numerical computation that follows ADI (Alternating Direction Implicit) algorithm. The local sea bottom is uneven and turns into a moderately shallow water due to presence of a ridge-like bottom near the coast. The bottom configuration is from a location off Nova Scotia coast in Canada. Detail results and discussions are presented
