Abstract

A new quasi-3D numerical model has been developed to investigate the hydrodynamics and morphodynamic processes associated with a series of surface piercing breakwaters. The model utilizes a detailed 1DV sand transport module to predict transport rate at each grid nodes, coupling with an intra-wave period wave module and depth-averaged flow module. Model results have been compared with measurements from a laboratory study of the offshore breakwater scheme outside Elma, west Essex, UK with satisfactory agreements. The model-date comparison also indicates clearly that the interaction between adjacent embayment is important factor in determine the morphological evolution.
