Pre-monsoon hydrodynamic modeling of Goa coast, West coast of India
Attempt has been made to characterize the hydrodynamic regime around the coastal waters of Goa for a pre-monsoon season, using MOHID, a two-dimensional finite volume model. The numerical model was forced with tides at open boundaries and calibrated using measured water levels and currents, during pre-monsoon season. The modeled water levels and currents were compared with field observations and found to be satisfactory, with correlation of 0.97 for water levels, 0.79 for zonal currents, and 0.84 for meridional currents. The ratio of diurnal (O1, K1) and semidiurnal (M2, S2) constituents was 0.63, suggesting that tides in this region are mixed, mainly semidiurnal in nature. The variation in amplitude of tidal constituents from the open boundary to the mouth and upstream of the Mandovi and Zuari estuaries has been modeled and compared with previous field studies and found to be satisfactory. The details of numerical scheme, methodology, and results are discussed in this paper.
