Doab is a term used in South Asia for the tract of land lying between two confluent rivers. It is similar to an interfluve. In the Oxford Hindi-English Dictionary, R. S. McGregor defines it as from Persian do-āb "a region lying between and reaching to the confluence of two rivers."
In any doab, khadir land (green) lies next to a river, while bangar land (olive) has greater elevation and lies further from the river

North India, also called Northern India, is a geographical and broad cultural region comprising the northern part of India wherein Indo-Aryans form the prominent majority population. It extends from the Himalayan mountain range in the north to the Indo-Gangetic plains, the Thar Desert, the Central Highlands and the northwestern part of the Deccan plateau. It occupies nearly three-quarters of the area and population of India and includes all of the three mega cities of India: Mumbai, Delhi and Kolkata. In a more specific and administrative sense, North India can also be used to denote the Indo-Gangetic Plain within this broader expanse, stretching from the Ganga-Yamuna Doab to the Thar Desert.
