Doab
The Doab is a crescent-shaped region of Uttar Pradesh state, in north-central India. It lies between the Ganges and Yamuna rivers, and consists of a flat alluvial plain.
The Doab figures strongly in Vedic history and myth. It is the home of many of the earliest Vedic cities and states; the epic Mahabharata is set in the Doab, revolving around the city of Hastinapura.
The Raichur Doab is the triangular region of Andhra Pradesh and Karnataka states which lies between the Krishna River and its tributary the Tungabhadra, named for the town of Raichur.
