Khambhat, formerly known as Cambay, is a city and a municipality in Anand district in the Indian state of Gujarat. It was formerly an important trading center, although its harbour has gradually silted up, and the maritime trade has moved elsewhere. Khambhat lies on an alluvial plain at the north end of the Gulf of Khambhat, which is noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambhat.
