Indian Rivers and Waterways

Kanpur is where the Ganga becomes most polluted due to discharges from tanneries, textile industries, and sewage. The city has numerous industries releasing untreated effluents directly into the river, making it a critically polluted stretch.

The Indira Gandhi Canal, a major irrigation project in northwestern India, originates at the Harike Barrage in Punjab. This barrage is constructed just below the confluence of the Sutlej and Beas rivers. Thus, Harike Barrage serves as the direct source for the canal's water supply.

The Indus river system includes several major tributaries: Sutlej, Beas, Ravi, Chenab, and Jhelum. The Bhagirathi is a source stream of the Ganges river system, flowing entirely independent of the Indus basin.

The Saryu River (also known as Ghaghara) flows near Ayodhya in Uttar Pradesh. Ayodhya, an ancient city with religious significance, is situated on the banks of this river. The Ganga and Yamuna are major rivers but flow elsewhere, and the Krishna River flows through southern India.

The Sundarbans delta is formed by the confluence of the Ganga (Ganges) and Brahmaputra rivers (along with Meghna). This delta spans Bangladesh and India and is the largest mangrove forest in the world. The other options list rivers from different regions (Punjab rivers).

The Colorado River carved the Grand Canyon over millions of years and continues to flow through it today. The Mississippi River flows through the central United States, while the Apalachicola is in Florida and the Kootenay is in the Pacific Northwest.

The Narmada River flows through a rift valley formed between the Vindhya and Satpura mountain ranges. Rift valleys are created when tectonic plates pull apart, and the land between them drops down to form a valley.

The Betwa River is a tributary of the Yamuna River, not the Ganga. Son, Ghaghara (also spelled Ghaggar), and Kosi are all direct tributaries that flow into the Ganga river system.

The Sutlej River is a tributary of the Indus River system, not the Ganga. Bhagirathi is a headstream of the Ganga, Ghaghara is a major left-bank tributary, and Damodar flows through the Ganga basin (joining via the Hooghly). The Sutlej originates in Tibet and joins the Indus in Pakistan, making it geographically part of the Indus system.

The Chambal River is a tributary of the Yamuna River, which itself joins the Ganga. It is not part of the Brahmaputra system. Manas, Teesta, and Kopili are all tributaries of the Brahmaputra River, flowing through Assam and surrounding regions.

Kosi is a tributary of the Ganga River, not the Indus. Jhelum, Chenab, and Ravi are all major tributaries of the Indus River, flowing through Punjab and into Pakistan. The Kosi originates in Nepal and joins the Ganga in Bihar.

The Godavari is the largest river in Peninsular India by length (about 1,465 km) and drainage area. It is often called the 'Vriddha Ganga' or Dakshin Ganga. While Mahanadi, Krishna, and Kaveri are major peninsular rivers, none match Godavari's size or discharge volume.

Manali is situated on the banks of the Beas River in the Kullu valley. The river originates from Beas Kund and flows through the town, making it integral to Manali's geography.

The Chambal River originates from Mhow in the Vindhya Range of Madhya Pradesh. It flows through Rajasthan and Madhya Pradesh before joining the Yamuna River. Bhind, Ratlam, and Ujjain are cities located near or along the Chambal but are not its source.

The Hirakud Dam is built across the Mahanadi River in Odisha and is one of the longest dams in the world. It was the first major multipurpose river valley project after India's independence. The Godavari, Damodar, and Kosi rivers have different dam projects like the Nagarjuna Sagar, Damodar Valley Corporation, and Kosi Project respectively.
