摘要
A two-dimensional hydrodynamic model was set up and validated for the west coast of India. The spatio-temporal variation of the tidal constituents for a 110 km stretch of the southwest coast of India was then studied by setting up a fine grid model. The study brings out variability in the shallow water constituents and their selective amplification. Within the Cochin estuary, the amplitudes of almost all the major tidal constituents show a gradual reduction upstream compared to other locations. The shallow water constituents show significant amplification and Z0, the constituent related to mean sea level shows five-fold amplification within the estuary.
