Question

The fertile land between two rivers is called

1. A. Drainage basin
2. B. Watershed
3. C. Doab (Correct answer)
4. D. Lowland or terrain

Correct Answer

Option C — Doab

Detailed Solution & Explanation

The correct answer is Doab.

Key Points

• Doab denotes the fertile alluvial tract lying between two converging rivers; the term is Persian, from *do* (two) and *ab* (water).
• The best-known example is the Ganga-Yamuna Doab in Uttar Pradesh, among India's most agriculturally productive regions.
• Punjab's historic divisions — Bari, Rachna, Chaj and Sindh Sagar Doabs — are named on the same principle.
• A drainage basin is the whole area drained by a river, and a watershed is the divide between two basins; neither describes land between rivers.

Additional Information

• The same Persian roots name the region of Punjab — *panj* (five) and *ab* (water), the land of five rivers.
• The historic doabs of the Punjab plain are worth knowing as a set:
  • Bist Jalandhar Doab — between the Beas and the Sutlej
  • Bari Doab — between the Beas and the Ravi
  • Rechna Doab — between the Ravi and the Chenab
  • Chaj Doab — between the Chenab and the Jhelum
  • Sindh Sagar Doab — between the Jhelum and the Indus
• Their alluvial soil makes doabs among the most agriculturally productive land in the subcontinent.
