Estuarine biogeochemistry plays a key role in the cycling of biological and chemical parameters. In the present study, a first attempt has been made towards the coupling of a realistic three-dimensional estuarine circulation model with biophysical model in the Hooghly Estuary (21°36′–22°16′N and 87°42′–88°15′E) to simulate and capture the varying effect of plankton biomass with response to river discharge and tidal effect. In-situ observational data for physico-chemical and biological parameters were collected from different sampling stations during 2003–2010 are assimilated using successive over relaxation method (SOR) and multiscale objective analysis (OA) and incorporated in Regional Ocean Modeling System (ROMS) to setup a higher resolution both in horizontal (0.5 km × 0.5 km) and vertical (8 vertical levels) biogeochemical model. Strong tidal influence with sliding growth of phytoplankton (less than 1mg/l) towards south and low dissolved oxygen (DO) is low (5.27 mg/l) in the Haldi River mouth also affects water quality.
