Water Transport in India: Inland Waterways and Oceanic Routes (Class 12 Geography, India: People and Economy, Chapter 7)

Updated 16 October 2026 · Fact-checked

Water transport is the cheapest, fuel-efficient and eco-friendly mode for heavy and bulky goods. India has 14,500 km of navigable inland waterways (about 1 per cent of transport), 111 National Waterways since the Act of 2016, and oceanic routes along a 7,517 km coast served by 12 major and 200 minor ports that carry about 95 per cent of foreign trade by volume.

Compare the two types: inland waterways carry only about 1% of transport, while ports on the 7,517 km coast handle about 95% of foreign trade by volume.

Understand Water Transport in India

Why this topic matters. The syllabus lists water transport (inland waterways and oceanic routes) under Chapter 7. CBSE has asked National Waterway stretches by diagram, matching and statements, so know Table 7.3 well. The chapter has no map item (the syllabus lists Nil for Chapter 7); the ports are covered in Chapter 8.

1. Why water transport. It is the cheapest means of transport, most suitable for heavy and bulky material, fuel-efficient and eco-friendly. It is of two types: inland waterways and oceanic waterways.

2. Inland waterways.

The chief mode of transport before the railways; they then faced tough competition from road and rail, and the diversion of river water for irrigation made them non-navigable in large parts of their courses.
India has 14,500 km of navigable waterways, contributing about 1 per cent to transportation. They comprise rivers, canals, backwaters, creeks and so on.
Inland Waterways Authority set up in 1986 for the development, maintenance and regulation of national waterways.
To create a wide network and promote inland water transport as an economical, environment-friendly supplementary mode to rail and road, 111 inland waterways (including the 5 declared earlier) were declared National Waterways (NWs) by the National Waterways Act, 2016. The Authority has also identified 10 other waterways that could be upgraded.

3. Table 7.3: the first five National Waterways.

NW 1: Prayagraj-Haldia (1,620 km); navigable by mechanical boats up to Patna and by ordinary boats up to Haridwar; three parts: Haldia-Farakka (560 km), Farakka-Patna (460 km), Patna-Prayagraj (600 km).
NW 2: Sadiya-Dhubri (891 km); the Brahmaputra is navigable by steamers up to Dibrugarh and is shared by India and Bangladesh.
NW 3: Kottapuram-Kollam (205 km): 168 km of west coast canal with the Champakara canal (14 km) and the Udyogmandal canal (23 km).
NW 4: specified stretches of the Godavari and Krishna with the Kakinada-Puducherry stretch of canals (1,078 km).
NW 5: specified stretches of the Brahmani, the Matai river, delta channels of the Mahanadi and Brahmani, and East Coast canals (588 km).

4. Kerala backwaters. The backwaters (Kayal) of Kerala have special significance: cheap transport and a draw for a large number of tourists. The famous Nehru Trophy Boat Race (Vallamkali) is held there.

5. Oceanic routes.

Coastline of about 7,517 km including islands; 12 major and 200 minor ports support the routes.
About 95 per cent of India's foreign trade by volume and 70 per cent by value moves through ocean routes. They are also used for transport between the islands and the rest of the country.

Inference (ours, not NCERT). The gap between the 95 per cent volume share and 70 per cent value share suggests that other modes carry goods of high value per unit; NCERT's Chapter 8 says air transport suits high-value and perishable goods, but the link is our reading.

Water Transport in India in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Oceanic routes and islands

Suppose a cargo ship carries cement and food for an island territory from a mainland port, and on its return trip carries local produce back.

Which use of oceanic routes is this, other than foreign trade?

Try it first, then show the solutionSolution

NCERT: oceanic routes are used for international trade and also for transportation between the islands and the rest of the country.
Twelve major and 200 minor ports provide infrastructural support to these routes.

Answer: Transport between the islands and the rest of the country.

Memory hook: Sea links connect islands to the mainland.

Why a river stopped carrying boats

Imagine that a river once carried grain boats, but barrages and canals now take most of its water to fields, and the channel is too shallow for boats for much of its course.

Which NCERT reason does this match, and what was the other reason for the decline of inland waterways?

Try it first, then show the solutionSolution

Diversion of river water for irrigation purposes made inland waterways non-navigable in large parts of their courses.
The other reason is tough competition from road and railway transport.

Answer: Diversion of river water for irrigation; the other reason is competition from road and rail.

Memory hook: Fields drink, boats stop.

Answer: The Inland Waterways Authority was set up in 1986 for the development, maintenance and regulation of national waterways in the country. To create a wide waterways network and to promote inland water transport as an economical, environment-friendly supplementary mode of transport to rail and road, 111 inland waterways, including the 5 declared earlier, were declared National Waterways by the National Waterways Act, 2016. The Authority has also identified 10 other inland waterways which could be upgraded.

Example 6: HOTS: volume and value of ocean-borne trade · 5 marks · Long answerHOTS / competency

NCERT says about 95 per cent of India's foreign trade by volume and 70 per cent by value moves through ocean routes. Work out the share carried by other routes in each case, compare the value carried per unit of volume by the two groups, and give a reason, labelling inference. (5 marks)

Try it first, then show the solutionSolution

Other routes (1 mark): 100 - 95 = 5 per cent by volume; 100 - 70 = 30 per cent by value (our arithmetic).
Comparison (2 marks): ocean routes carry 70 per 95, about 0.74 value units per volume unit; other routes carry 30 per 5 = 6, about eight times as much value per unit of volume (our arithmetic).
Reason (2 marks): inference that other modes carry goods of high value per unit; NCERT Chapter 8 says air transport suits high-value or perishable goods, and Chapter 7 says water transport suits heavy and bulky material.

Answer: Ocean routes carry about 95 per cent of foreign trade by volume and 70 per cent by value, so other routes carry about 5 per cent by volume and 30 per cent by value (our subtraction).

Per unit of volume, ocean routes carry 70 / 95, about 0.74 units of value, while the other routes carry 30 / 5 = 6 units, roughly eight times as much (our arithmetic on NCERT shares).

Our inference is that ocean routes mainly carry heavy and bulky goods, which NCERT says water transport suits best, and that the goods moving by the other routes have a much higher value for the same volume. This is supported by Chapter 8, where NCERT says air transport takes the least time and suits high-value or perishable goods, but NCERT does not itself explain the two percentages.

Where students lose marks in Water Transport in India

The slips examiners see most often, and what to write instead.

Mistake: Swapping 95 per cent and 70 per cent
Both figures describe ocean trade.
Wrong working
About 70 per cent of foreign trade by volume and 95 per cent by value goes by sea.
Right working
About 95 per cent by volume and 70 per cent by value.
Do this: Volume 95, value 70.
Usually costs: 1 mark.
Mistake: Treating 111 as the number of new waterways
The number includes the earlier ones.
Wrong working
The Act of 2016 declared 111 new waterways in addition to 5.
Right working
111 inland waterways, including the 5 declared earlier, were declared National Waterways by the 2016 Act.
Do this: 111 includes the first 5.
Usually costs: 1 mark.
Mistake: Misplacing NW 2 and NW 3
Both have names starting with unfamiliar towns.
Wrong working
NW 3 is the Brahmaputra from Sadiya to Dhubri.
Right working
NW 2 is Sadiya-Dhubri (Brahmaputra, 891 km); NW 3 is Kottapuram-Kollam in Kerala (205 km).
Do this: Two is east, three is Kerala.
Usually costs: 1 mark.
Mistake: Saying inland waterways carry most of the load
The advantages of water transport are stressed in the text.
Wrong working
Inland waterways are the major mode of transport in India now.
Right working
They contribute about 1 per cent of transportation; oceanic routes carry the bulk of foreign trade.
Do this: Advantage is not share.
Usually costs: 1 mark.

Exam tips

Write each National Waterway as stretch plus length, for example Prayagraj-Haldia, 1,620 km.
Do not mix the Chapter 7 ocean-route figures (95 and 70 per cent) with Chapter 8 port details.
Check that your NW 1 and NW 3 parts add up before writing them.

Practice questions on Water Transport in India

Write each answer on paper first. Open the hint only if you are stuck, and the answer only when you have finished.

Q1 · 1 mark · MCQBoard level
Apart from international trade, oceanic routes in India are also used for:
(A) tourism boat races only
(B) transportation between the islands and the rest of the country
(C) irrigation of coastal areas
(D) river navigation up to Haridwar
Hint
NCERT mentions one more use.
Answer
(B) transportation between the islands and the rest of the country.
Q2 · 2 marks · Very short answerHarder board level
National Waterway 3 (Kottapuram-Kollam, 205 km) includes 168 km of west coast canal, the Champakara canal (14 km) and the Udyogmandal canal (23 km). Check that the parts add up and find the percentage share of the west coast canal, to the nearest whole number. (2 marks)
Hint
Add the three parts; divide 168 by 205.
Answer
168 + 14 + 23 = 205 km, which matches the stated length. The west coast canal share is 168 / 205 x 100 = 82 per cent (our own arithmetic on the NCERT figures).
Q3 · 1 mark · MCQHarder board level
National Waterway 1 is 1,620 km long and India has 14,500 km of navigable waterways. About what share of the navigable length does NW 1 represent?
(A) 1.1 per cent
(B) 11 per cent
(C) 16 per cent
(D) 0.1 per cent
Hint
Divide 1,620 by 14,500.
Answer
(B) 11 per cent. 1,620 / 14,500 x 100 = 11.2 (our own arithmetic; a rough indicator, since the two NCERT figures are not stated to be on the same basis).
Q4 · 3 marks · Short answerHarder board level
Why did inland waterways, once the chief mode of transport in India, decline, and what role does NCERT now assign them? (3 marks)
Hint
Two reasons; one role.
Answer
Inland waterways were the chief mode of transport before the railways, but they faced tough competition from road and railway transport. Diversion of river water for irrigation also made them non-navigable in large parts of their courses. NCERT now wants them promoted as an economical, environment-friendly supplementary mode of transport to rail and road, which is why 111 waterways were declared National Waterways by the Act of 2016.
Q5 · 2 marks · Very short answerBoard level
Name four kinds of water bodies that make up India's inland waterways network and give its navigable length. (2 marks)
Hint
Rivers, canals and two more.
Answer
The network comprises rivers, canals, backwaters, creeks and so on, with 14,500 km of navigable waterways.
Q6 · 3 marks · Short answerHOTS / competency
A student argues: "Water transport is the cheapest and best for heavy goods, so inland waterways should now replace the railways." Evaluate this claim using NCERT. (3 marks)
Hint
Advantages are real, but look at the share and the stated role.
Answer
NCERT does say water transport is the cheapest, most suitable for heavy and bulky material, fuel-efficient and eco-friendly. But inland waterways contribute only about 1 per cent of India's transportation, they lost ground to road and rail, and diversion of river water for irrigation made them non-navigable in large parts. NCERT describes them as a supplementary mode to rail and road, not a replacement. The claim therefore overstates the case; the verdict is our inference from these NCERT facts.
