What is meant by the term "DOAB"?
Answers
Explanation:
The rivers coming from northern mountains are involved in depositional work.In the lower course, due to gentle slope, the velocity of the river decreases which results in the formation of riverine islands. The word 'do' means two and 'ab' means water. Doab refers to the riverine island where two rivers meet. Punjab is named similarly because it is land of five rivers.
Doab is a term used for the plot of land prevailing within two confluent or converging rivers. The Ganges-Yamuna doab signifies the low-lying alluvial region within the Ganges and Yamuna waterways stretching from the Sivalik Hills to the two streams' convergence at Allahabad.
Answer:
Doab is a word used particularly in Pakistan and India to describe a region of land that lies between two confluent or converging rivers. The regions where doabs are found are typically near rivers, and they are primarily low lying areas such as floodplain and are often highly fertile. Mostly they are formed as a result of sedimentation and agriculture is widely practiced in regions with doabs.
The northern part of Pakistan and India has numerous rivers flowing in the region forming different doabs. The Indo-Gangetic plains are made of alternating parts of river Bangar and Khadir. The Bangar doab is not prone to flooding because it lies on a higher altitude compared to other doabs and subsequently they are less fertile. The Khadir is also referred to as Naili or Nali, and it is the region lying in the north of Haryana and the fertile prairie lying between southern ends of Saraswati channel and Ghaggar River which receives floods when there are rains. The Barani doab also lies within the Bangar region, and it is an area where rain-fed dry farming is widely practiced, but currently, it depends on tube wells for irrigation purposes.
