CIRCULATION AND SALINITY IN HOOGHLY ESTUARY - A NUMERICAL STUDY

Numerical models are presented for tidal flow and salinity in the Hoog hly estuary, along the east coast of India. A depth-averaged numerical model coupled with a one-dimensional model is discussed. The model ha s been validated with the available observations for the dry and wet s easons. The influence of storm surges on the circulation is also discu ssed in this section. A multi-level laterally averaged model for the e stuary is also described. The vertical structure of the currents and s alinity are validated with spring observations during both wet and dry seasons.
