National Waterways: IWAI & Inland Navigation Corridors Questions

Reviewed by the Master10 Editorial Board for accuracy, clarity and competitive-exam relevance.Editorial Policy
Inland water navigation in India derives constitutional authority from Entry 24 of the Union List in the Seventh Schedule, which empowers Parliament to declare inland waterways as national waterways and regulate shipping upon them. Mechanically propelled navigation on non-national waterways falls under Entry 32 of the Concurrent List, while states regulate local riverine traffic under Entry 13 of the State List. The apex institutional agency directing inland navigation is the Inland Waterways Authority of India, constituted on October 27, 1986, under the Inland Waterways Authority of India Act, 1985, with headquarters in Noida, Uttar Pradesh. To consolidate river transport development, Parliament enacted the National Waterways Act, 2016, which repealed five earlier statutes and designated 111 inland waterways spanning over 20,000 kilometres across 24 states as National Waterways, prioritizing low-emission bulk cargo transport.

The foundational navigational corridor is National Waterway 1, extending 1,620 kilometres along the Ganga-Bhagirathi-Hooghly river system between Prayagraj in Uttar Pradesh and Haldia in West Bengal. Capacity expansion on this artery is executed via the Jal Marg Vikas Project, assisted financially and technically by the World Bank through a 375 million dollar loan. The project constructed Multi-Modal Terminals at Varanasi, Sahibganj, and Haldia, an Inter-Modal Terminal at Kalughat, and a modern parallel navigational lock at Farakka, maintaining a minimum draft of three metres for commercial barges. Other operational corridors include National Waterway 2, covering 891 kilometres on the Brahmaputra River from Sadiya to Dhubri; National Waterway 3, running 205 kilometres along Kerala's West Coast Canal; National Waterway 4 along the Krishna and Godavari rivers; and National Waterway 5 along the Brahmani and Matai rivers.

Cargo transit across these riverine networks utilizes Roll-on/Roll-off and Roll-on/Passenger vessels, facilitating multimodal freight transfers while integrating with the Indo-Bangladesh Protocol routes to enable river-sea transit to northeast India. Energetically, inland shipping requires roughly 0.25 to 0.30 megajoules of energy per ton-kilometre, compared to 1.0 megajoule for railways and 1.5 megajoules for road transport, yielding significant carbon reduction and lower logistics costs. In civil services and staff selection commission assessments, frequent evaluative topics include the statutory authority of the Inland Waterways Authority of India, modal infrastructure delivered under the Jal Marg Vikas Project, navigational extents of National Waterways 1 through 5, and the comparative energy efficiency of riverine cargo vessels over highway transport.

River Information Services (RIS), an automated vessel traffic tracking and navigation assistance system, was first deployed on NW-1 between Sagar and Farakka.
#14
National Waterway 16 covers 121 kilometres along the Barak River from Lakhipur to Bhanga in Assam, linking Northeast India to Chittagong Port.
#15
Section 14 of the National Waterways Act 2016 stipulates that states retain riparian ownership of water extraction and local irrigation rights.

Educator's Insight
Inland waterways provide fuel-efficient transit corridors for transporting bulk cargo across India's river basins. Governed by the Inland Waterways Authority of India since 1986, river navigation expanded after the National Waterways Act of 2016 designated 111 National Waterways. The flagship route is National Waterway 1, spanning 1,620 kilometers along the Ganga-Bhagirathi-Hooghly system from Prayagraj to Haldia, supported by modern multimodal freight terminals at Varanasi and Sahibganj and a navigational lock at Farakka.
In UPSC prelims and State PSC examinations, river stretches are standard matching questions. Memorize the primary routes: NW-1 runs from Prayagraj to Haldia on the Ganga, NW-2 spans Sadiya to Dhubri on the Brahmaputra, and NW-16 covers the Barak River. Watch out for a recurring conceptual trap: declaring a national waterway brings navigation under Parliament via Entry 24 of the Union List, but states retain their riparian rights for irrigation and local water use.
