Only statement 2nd is correct.

Inland Waterways Transport

• About: It refers to the movement of people and goods on navigable waterways such as rivers, canals, lakes, and other inland water bodies. 

• Legislative Framework:  

• Inland Waterways Authority of India Act, 1985: Led to the formation of Inland Waterways Authority of India (IWAI) in 1986. 

• IWAI is an autonomous organization responsible for the development, maintenance, and regulation of NWs. 

• National Waterways Act, 2016: Declared 111 inland waterways as NWs for enhanced shipping and navigation. 

• Inland Vessels Act, 2021: Replaced the Inland Vessels Act, 1917, introduced uniform regulations for inland vessels, ensuring safety, navigation, and compliance across India.

• Criteria to be as a National Waterway: A waterway qualifies as a National Waterway if it is navigable by propelled vessels, and 50 km long (except for urban areas and intra-port traffic). 

• It should serve multiple states or connect a prosperous hinterland or major ports or support strategic navigation for national security or link unserved areas lacking other transport modes. 

Hence option 1st is correct.
