The Gulf of Khambhat is an inlet located on the Arabian Sea along the India’s west coast, bordering the states of Gujarat and Maharashtra. The northern Gulf of Khambhat experiences high tidal range of 12 m comparable to that of Bay of Fundy. In this study we discuss about the two-dimensional numerical model for the Gulf of Khambhat that has been developed using Delft3d flow module to understand the dynamics of complex tidal regime. The model domain extends from latitude 18.2333 N to 22.4333 N and longitude to 69.6833 E to 73.0666 E and covers an area of approximately 1300 square km. The model has been forced at the open boundary (mouth of the Gulf) with tidal constituents extracted from the TOPEX/Poseidon 7.2 Global Inverse Tidal Model at the open boundary. In order to achieve a precise calibration, sensitivity analysis has been performed for bed roughness coefficients with different grid resolutions. The model was calibrated against the observed water levels, currents for the spring and neap tidal cycles of the monsoon season, and for the non-monsoon season. Model is also validated with observed currents and drogue paths. Computed water levels in the Gulf of Khambhat at locations Diu, Dahej, and Nirma showed good agreement with the observed water levels during monsoon and non-monsoon seasons. Similarly, computed currents in the Northern Gulf at Adhelai, Dadar, and Narmada exhibited good agreement with the measured current speeds during monsoon and non-monsoon seasons.
