About Khambhat
Khambhat, also known as Cambay, is a town and the surrounding urban agglomeration in Khambhat Taluka, Anand district in the Indian state of Gujarat. It was once an important trading center, but its harbour gradually silted up, and the maritime trade moved elsewhere. Khambhat lies on an alluvial plain at the north end of the Gulf of Khambhat, noted for the extreme rise and fall of its tides, which can vary as much as thirty feet in the vicinity of Khambhat. Khambhat is known for its halvasan, sutarfeni and kites (patang), and for sources of oil and gas.
