Indian Rivers and Waterways

The Cauvery river dispute between Tamil Nadu and Karnataka escalated dramatically in the 1990s, with the Cauvery Water Disputes Tribunal providing its interim award in 1991. The dispute centers on water sharing during drought years, with Tamil Nadu claiming historic usage rights and Karnataka asserting its position as an upstream state. This is one of India's most persistent inter-state river conflicts.

Medha Patkar is best known as the leading activist of the Narmada Bachao Andolan (NBA), a movement opposing the construction of large dams on the Narmada river. The NBA focused on issues of displacement, environmental degradation, and the rights of tribal communities affected by the Sardar Sarovar Dam project. Her activism brought international attention to the human costs of large dam projects in India.

The Ganga has the largest river basin in India, covering approximately 26% of the country's geographical area. The Ganga basin spans across 11 states and supports over 40% of India's population through its extensive network of tributaries including the Yamuna, Ghaghara, and Gandak. This makes it significantly larger than the basins of the Indus, Narmada, or Brahmaputra rivers.

The Brahmaputra river flows through Assam and is notorious for frequent course changes, particularly in its braided channel sections. This behavior causes severe bank erosion and flooding in the Assam valley. The river carries enormous sediment loads from the Himalayas, which causes it to constantly shift its course, especially during the monsoon season. This makes the Brahmaputra one of the most unstable rivers in the world.

The Amazon River is the world's largest by discharge volume and width, especially during the wet season when it can reach 40 kilometers wide. The Nile is the longest river, while the Mississippi and Brahmaputra are significant but narrower.

The Ganges river (Ganga) was officially declared India's national river in 2008. Therefore, the statement 'Ganges is not National River' is false, making option B correct.

Patna is situated on the banks of the Ganga river. Ujjain is on the Shipra river, Ayodhya is on the Sarayu river, and Digboi is in Assam on the Burhi Dingring river.

Ujjain is situated on the banks of the Shipra (Kshipra) River in Madhya Pradesh. The city is one of the seven sacred cities (Sapta Puri) in Hinduism and hosts the Kumbh Mela.

The Beas River originates from Beas Kund, a glacial lake located in the Dhauladhar range of the Himalayas in Himachal Pradesh. It is a tributary of the Sutlej River and flows through the Kullu Valley. Beas Kund is considered the source of this important river in the Indus river system.

The Chenab River originates from the confluence of the Chandra and Bhaga rivers in the Lahaul region of Himachal Pradesh. These two rivers join at Tandi to form the Chandrabhaga (Chenab), which then flows through Jammu and Kashmir. The river is an important tributary of the Indus system and has significant hydroelectric potential.

Amarkantak is a plateau region in Madhya Pradesh where three major rivers originate within 20 kilometers of each other: the Narmada (flowing west), the Mahanadi (flowing east), and the Son (a tributary of the Ganges). This unique convergence of river sources makes it a significant geographical feature and pilgrimage site in central India. Ooty, Raipur, and Bhilai are not associated with these river origins.

The Krishna River originates from Mahabaleshwar in the Satara district of Maharashtra, at an elevation of about 1,337 meters above sea level. The specific source is a spout from the mouth of a statue of a cow in the ancient Krishna Bai Temple. Mahakaleshwar is in Ujjain (associated with the Shipra River) and Maharajeshwar is not related to this river.

The Kaveri River originates from Talakaveri in the Kodagu district of Karnataka, at the foothills of the Western Ghats. There is a sacred tank (Brahmagiri hill) and a temple marking the source. Ooty, Mysore, and Kodaikanal are all in South India but are not the river's origin point. Kaveri flows through Karnataka and Tamil Nadu before reaching the Bay of Bengal.

The Ganges (Ganga) originates from the Gangotri Glacier in Uttarakhand, specifically at Gaumukh (cow's mouth), which is about 19 km from the Gangotri temple town. Mansarovar is a lake in Tibet associated with the Sutlej River. Shimla is a hill station in Himachal Pradesh. Yamunotri is the source of the Yamuna River, not the Ganges.

Lake Mansarovar (and nearby Mount Kailash) in Tibet is the region near the origins of three major rivers: the Indus (flows through Pakistan), the Brahmaputra (flows through Tibet, India, and Bangladesh), and the Sutlej (a tributary of the Indus). Leh is in Ladakh, Lhasa is the capital of Tibet, and Shimla is in Himachal Pradesh; none are the source region. Note that the actual glaciers are distinct but near this sacred lake.
