Numerical modelling of tides and storm surges in the Bay of Bengal

Abstract

This study generated improved reliable bathymetric datasets for the continental shelf of the Indian Ocean. Simulation of tides and generation of co-range and co-tidal charts of the major semi-diurnal and diurnal constituents for the Bay of Bengal were done. A storm surge model was developed to simulate total water levels and derived surges caused by low pressure systems identified during the past 27 years (1974-2000) in the Bay of Bengal. Study also estimated the return levels of extreme sea level events at major coastal stations along the east coast of India.
