The gulf of Khambhatt formerly known as the gulf of Cambay is a trumpet shaped inlet of the Arabian sea in the state of Gujarat on the west coast of India. It has a high tidal range and velocity thanks to it's shape and orientation with the south-west monsoon winds. Navigation through the gulf is no picnic because of it's shoals and sandbanks.
In May 2001, it was announced that ruins of an ancient civilization has been found near the banks of the Gulf of Khambhatt. The site was found by the National Institute of Ocean Technology (NIOT) while conducting a routine pollution check using sonar. The site was found to have regularly spaced geometric structures believed to be dwelling places, a granary, a citadel, a bath and a drainage system. These structures were believed to predate the Indus Valley Civilization, the oldest known civilization near the area.
