【 摘 要 】

Mathematical modelling ofnearshore oceanographic conditions was carried out, in connection with a large industrial fishery harbour planned to be implemented in a coastal stretch protected by two reefal systems, on the western coast of Sri Lanka. MIKE 21, a two dimensional mathematical modelling system with a wide range of coastal engineering applications, and LITPACK, a one dimensional coastal processes modelling system, were extensively used in this study. The major features of modelling were the successful simulation of wave transmission over reefs and wave overtopping mass flux induced currents behind the innermost reef. The validated model under existing conditions was used to optimise the harbour layout with safe navigational access, acceptable wave agitation within the basin and adequate sediment by-pass capacity at the entrance. The wave and other hydrodynamic parameters for the economical design of harbour breakwaters were also obtained. A well calibrated hydrodynamic model covering most of the western coast of Sri Lanka also evolved as a byproduct of this study.
