Question

The land between two rivers is called___
a. Doab
b. Bhabar
c. Terai
d. Khadar

Answer 1

Hint: The word 'do' means two and 'ab' means water, respectively. Doab relates to the riverine island where two streams converge.

Complete answer:
Doab is a term used for the tongue, or tract of land lying between two converging, or confluent, rivers in India and Pakistan. It's an interfluve-like item. R. S. McGregor defines it as a zone between and reaching the confluence of two rivers from Persian do-āb." It describes the flat alluvial tract between the rivers Ganges and Yamuna extending from the Sivalik Hills to the confluence of the two rivers at Allahabad. It is also referred to as Ganges-Yamuna Doab or Ganga Doab. The area has an area of about 23,360 square miles; it is about 500 square miles.

The British Raj split the Doab into three administrative districts, namely the Upper Doab (Meerut), the Middle Doab (Agra) and the Lower Doab (Allahabad).
The Indo-Gangetic plains consist of alternating regions of rivers, khadar and bangar, since North India and Pakistan are run by a multitude of Himalayan rivers that divide the plains into doabs.

The doab areas near the rivers consist of low-lying floodplains, but typically very fertile khadar, and bangar, less prone to flooding but also less fertile on average, is the higher-lying land away from the rivers.

Khadir is also known as Nali or Naili, the fertile prairie tract between the Ghaggar river and the southern limits of the Saraswati channel depression, which is flooded during the rains, particularly in northern Haryana. The Barani is any low rain region within the bangar area where rain-fed dry agriculture is practised, which today depends on the irrigation tube wells.

Hence, the correct answer is option A.

Note:
Historically, for many years, villages in the Doabs have been officially known as khadir, khadir-bangar or bangar, and various agricultural tax rates have been applied based on a tiered scale of land productivity. Nahri is any canal-irrigated land that is an area irrigated by the channel/canal of Rangoi for the purpose of transporting Ghagghar river flood waters to dry areas.
