CAPF AC 2025 Q78: Geography – Transport & Infrastructure Geography
Consider the following pairs with reference to National Waterways (NW) in India and the associated rivers:
| NW No. | River |
|---|---|
| 1. NW-1 | Ganga |
| 2. NW-10 | Amba |
| 3. NW-100 | Tapi |
Which of the pairs given above is/are correctly matched?
- (a) 1 only
- (b) 1 and 2 only
- (c) 2 and 3 only
- (d) 1, 2 and 3
Answer: (d) 1, 2 and 3
Explanation
National Waterways and their rivers
How to think: the National Waterways Act, 2016 declared 111 waterways.
The first and best-known is NW-1; the others are numbered 2 to 111.
| NW | River and stretch | Match? |
|---|---|---|
| NW-1 | Ganga-Bhagirathi-Hooghly, Haldia to Allahabad (1,620 km) | Yes |
| NW-10 | Amba river, Raigad district, Maharashtra (45 km) | Yes |
| NW-100 | Tapi river, Hatnur dam to the Gulf of Khambhat (436 km) | Yes |
All three pairs are correct.
Answer: (d) 1, 2 and 3.
Why each option is right or wrong
- (a) Incorrect. Pairs 2 and 3 are also correct.
- (b) Incorrect. Pair 3 (NW-100, Tapi) is also correct.
- (c) Incorrect. Pair 1 (NW-1, Ganga) is also correct.
- (d) CORRECT. All three pairs match.
Key point
NW-1 Ganga (Haldia-Allahabad); NW-2 Brahmaputra (Dhubri-Sadiya); NW-3 West Coast Canal (Kollam-Kottapuram); NW-4 Krishna-Godavari; NW-5 East Coast Canal and Brahmani-Mahanadi; NW-10 Amba (Maharashtra); NW-100 Tapi.
Remember
NW-1 Ganga, NW-10 Amba, NW-100 Tapi: all three match.
Common mistakes
- Doubting NW-10 and NW-100 because they are lesser-known than NW-1 to NW-5.
- Confusing NW-100 (Tapi) with the Narmada.
- Thinking there are only five national waterways.
Exam tip
Educated guess: NW-1 and Ganga is a certain match, which removes (c). Rivers like Amba and Tapi are on the west coast and all appear in the 2016 list.
