or Gulf of Cambay
Inlet, Arabian Sea , on the northwestern coast of India, southeast of the Kathiawar Peninsula .
It is 120 mi (190 km) wide at its widest but rapidly narrows. It receives many rivers, including the Tapi and Mahi. Its orientation to the southwestern monsoon winds produces a high tidal range. All its ports have suffered from silting caused by tides and flood torrents. On its eastern side are Bharuch, one of India's oldest ports, and Surat . At the gulf's head is the city of Khambhat (pop., 2001 prelim.: 80,439), which was mentioned by Marco Polo as one of India's most important seaports.
