| Abstract | Indian Institute of Science, Bengaluru, Karnataka 560012, India.[Email: vsamiksha@nio.org, ]Received 31 January 2013; revised 20 February 2013 Present study is the coastal circulation modelling off Ratnagiri under the influence of winds and tides. A two-dimensionalhydrodynamic model MIKE 21HD has been used to simulate tides and currents, and model results are in a good agreementwith the measurements. In July, representing the southwest monsoon, wind is relatively strong, onshore current componentis more pronounced; but, tidal variations are masked to a great extent by the wind driven circulation. Relatively strongerwinds of the order of 8 m/s, persisted for a longer period, and that contributed to the southward flowing coastal current whichis more consistent in its direction and magnitude. Meridional current has a prominent southward direction with a maximumalongshore speed of ~0.41 m/s. Zonal current is too weak to have a considerable impact on the circulation pattern. Prominentcirculation is southward, irrespective of the seasons.[Keywords: Tides, Winds, Coastal circulation, Monsoons, Arabian Sea] |
