Which of the following statements about floods in Bihar are correct?
- 1. Bihar is basically a plain area.
- 2. The major rivers of Bihar are long, with their catchments in the mountains.
- 3. Bihar is economically backward.
Of these:
- ANone of the above is correct
- BOnly 1 and 2 are correct
- CAll three are correct
- DOnly 1 is correct
Show answer and explanation
Correct answer: (c) All three are correct
Explanation
All three statements are correct.
- Statement 1: most of Bihar is a flat alluvial plain, so flood water spreads widely and drains away slowly.
- Statement 2: its major rivers, such as the Kosi, Gandak, Bagmati and Kamla, are long and have their catchments in the mountains of Nepal and Tibet, where heavy monsoon rain sends down huge volumes of water and silt.
- Statement 3: Bihar's economic backwardness adds to the damage: weak embankments, drainage and relief make it more vulnerable to floods.
