India moves the overwhelming majority of its freight by road and rail — even though its rivers already offer one of the cheapest ways to move heavy cargo, if only the water stayed deep enough to use them.
MCQ Questionsâś… Must Know
What a National Waterway is
- A National Waterway is a river, canal, or backwater stretch declared navigable by the Union government for cargo and passenger transport. India currently has 111 declared National Waterways.
The nodal agency
- The Inland Waterways Authority of India (IWAI), set up in 1986, develops and regulates this network. It handles dredging, terminal building, and navigation aids.
NW-1: the longest waterway
- National Waterway 1 runs along the Ganga-Bhagirathi-Hooghly river system, from Prayagraj to Haldia. At about 1,620 km, it is India’s longest declared waterway.
Other major waterways
- NW-2 uses the Brahmaputra in Assam. NW-3 links Kollam and Kottapuram in Kerala via the West Coast Canal. NW-4 runs on the Krishna and Godavari systems in Andhra Pradesh.
đź’ˇ Good to Know
Why cargo owners prefer water for bulk goods
- Moving cargo by river costs less per tonne-kilometre than road, and often less than rail too, for bulk goods. This makes waterways attractive for coal, cement, foodgrains, and containers.
A lower-emission alternative
- Inland water transport burns less fuel per tonne of cargo moved than road transport. Shifting freight to waterways cuts both logistics cost and carbon emissions.
Relieving road and rail congestion
- Every tonne moved by river is a tonne that doesn’t add to road or rail congestion. This matters most on corridors already running near capacity.
The Jal Marg Vikas Project
- The Jal Marg Vikas Project, with World Bank assistance, upgrades NW-1’s navigability between Haldia and Varanasi. It funds multi-modal terminals, including at Varanasi and Sahibganj.

🌟 Great to Know
Seasonal depth is the core physical constraint
- River depth varies sharply between monsoon and dry-season flow. Many stretches that are easily navigable in the monsoon become too shallow for loaded vessels later in the year.
Siltation demands constant dredging
- Rivers like the Ganga carry heavy silt loads, which build up on the riverbed over time. Keeping a channel navigable requires continuous, costly dredging, not a one-time fix.
Barrages complicate free flow
- Structures built for irrigation and flood control, like the Farakka Barrage, can obstruct free navigation and affect fish migration such as Hilsa runs. Waterway planning has to work around, not against, these existing structures.
Terminal infrastructure lags behind the river network
- A navigable river alone isn’t enough. Loading and unloading cargo efficiently needs multi-modal terminals connecting the waterway to road and rail, and this infrastructure has historically lagged behind the declared waterway network itself.
