Explanation: National Waterways in India are a significant part of the country's inland water transport system, designed to facilitate the movement of goods and people through waterways. The Government of India has declared several rivers and canals as National Waterways to promote economic development and improve connectivity.
National Waterway 3, which includes the West Coast Canal in Kerala Udyogmandal and Champakkara canals, is a vital waterway for the state of Kerala. The West Coast Canal, also known as the Kollam–Kottappuram Canal, is a 168-kilometer-long canal that connects the ports of Kollam and Kottappuram. The Champakkara canal, which is a part of this network, is a 20-kilometer-long canal that connects the Vembanad Lake to the Arabian Sea. These canals are crucial for the transportation of goods and people along the coast of Kerala, contributing significantly to the state's economy.
The Inland Waterways Authority of India (IWAI) manages these waterways and is responsible for their maintenance and development. The IWAI aims to improve the navigability of these waterways, enhance the infrastructure, and promote the use of inland waterways for transportation.
It is important to note that the numbering of National Waterways can sometimes be confusing, as they are not always in geographical order. National Waterway 3 is specifically designated for the West Coast Canal and Champakkara canals, and it is distinct from other waterways such as National Waterway 4 (Brahmaputra River), National Waterway 5 (Barak River), and National Waterway 6 (Mandovi-Zuari River system).
Understanding the specific canals and rivers that form part of each National Waterway is crucial for students preparing for competitive examinations, particularly those related to geography and transportation in India. This knowledge helps in comprehending the economic and logistical importance of these waterways in the context of regional development and transportation infrastructure.
