Description A barotropic model is developed for the shelf region off the central west coast of India, which includes the regions of Bombay High and Gulf of Khambhat, in order to simulate tides and tidal currents in the region. The model is forced by a composite tide along its open boundary, which runs approximately parallel to the 200 m isobath, based on the results from global tidal models. Results of a month long simulation are analysed harmonically to separate the major constituents, namely, M sub(2), S sub(2), K sub(1) and O sub(1). A comparison of the computed amplitudes and phases with the observations (International Hydrographic Bureau, Monaco) show a fairly good agreement. A comparison of modelled currents with those observed at a few selected stations also indicate that the model reproduces the observed currents well. To make use of the model the aim is to simulate the tidal constituents only to describe the tidal circulation in the region and to examine to what extent the observed currents are tidally influenced in this region
