Abstract
Gulf of Khambhat (GOK) is a very complex region with high tidal range and varied bed material along eastern and western coastline within the Gulf. In this study, a process-based model for the GOK is constructed to study the sediment transport pattern covering the entire Gulf. The investigation at hand showed that modelling sediment transport is an important tool for the decision makers and designers when it comes to interferences on coastal water bodies. As we know Gulf is a portion of the ocean that penetrates into the land and is generally larger and more deeply intended than bays, so they often make excellent harbours. The major rivers flowing in the Gulf of Khambhat are Sabarmati, Mahi, Vishwamitri and Narmada. All these rivers carry huge sediments and are dumped in the Gulf of Khambhat. Due to rapid industrialization along the Gulf huge coastal infrastructural development has been executed and planned along the Gulf coast which has induced a change in the morphology of this region. A morphological study based on hydrodynamic model was carried out and the model was calibrated and validated with the various measured data sets available at CWPRS, Pune. Hence, the results of the morphological study were reviewed for plausibility using the hydrodynamic results. A hydrodynamic flow modelling system based on a cell-centered finite volume method on an unstructured mesh has been used to simulate sediment transport and bed morphological changes under actions of currents and waves along the GOK coast. In the horizontal plane, an unstructured grid is used.
