Indian Rivers and Waterways

The Neva River flows through Leningrad (now St. Petersburg) in Russia. The Tagus flows through Portugal, the Thames through London, and the Mersey through Liverpool.

The Ravi River is one of the five rivers of Punjab and flows through Lahore. The Congo flows through Africa, the Rhine through Germany, and the Lifty is not a real river name.

The Tagus River flows through Lisbon, Portugal's capital city. The Thames flows through London, the Neva through Russia, and the Mersey through Liverpool.

Varanasi, one of the oldest continuously inhabited cities in the world and a major Hindu pilgrimage site, is situated along the banks of the Ganga River. The Yamuna flows through Delhi and Agra, while the Godavari is the second-longest river in India after the Ganga, and the Brahmaputra flows through Assam. This geographic fact makes Ganga the correct answer.

The Sundarbans delta is formed by the confluence of the Ganges and Brahmaputra river systems (with the Meghna river) in Bangladesh. The Ganges brings sediment from the Himalayas, while the Brahmaputra contributes massive water and sediment flow. Together they create the world's largest mangrove ecosystem. The Indus is in Pakistan, while Yamuna is a tributary of the Ganges.

The Brahmaputra flows through Assam and joins the Ganges (called Padma in Bangladesh) to form the world's largest delta at the Sundarbans. While the Brahmaputra meets the Ganges system, it technically joins the Padma (the Ganges' distributary) in Bangladesh. The Indus flows to Pakistan, Yamuna merges with Ganges earlier, and Damodar is a separate river system.

The Hwang Ho (Yellow River) in China is called the 'Yellow River' because of the massive amounts of yellow silt (loess) it carries, giving it a yellowish-brown color. It is the birthplace of Chinese civilization. The Thames is in England, Kosi in India/Bihar, and Tigris in West Asia (Iraq).

The Kumbh Mela is celebrated at four sacred river banks in India: Haridwar (Ganges), Prayagraj (confluence of Ganges, Yamuna, Saraswati), Nashik (Godavari), and Ujjain (Shipra). Since this question specifies Haridwar, the correct answer is the Ganges river, which is the most sacred river in Hinduism.

The Danube River originates in the Black Forest region of Germany (specifically from the confluence of Brigach and Breg streams in Donaueschingen) and flows through ten countries before emptying into the Black Sea. It is one of the principal rivers of Europe and the world.

The Ganges basin is the largest in India covering about 26% of the country's total area. The Godavari basin is the second largest, covering approximately 10% of India's geographical area, and is often called the 'Dakshin Ganga' or 'Ganges of the South'.

The Aravalli Range is a mountain range in northwest India running approximately 692 km across Gujarat, Rajasthan, Haryana, and Delhi. It acts as a water divide between the Indus river system (flows west and northwest) and the Ganga river system (flows east), making it a crucial physiographic feature of northern India.

The Luni River is the only major river in the arid region of Rajasthan that drains into the Rann of Kutch (a large salt marsh in Gujarat). It originates in the Aravalli Range and flows southwest through Rajasthan before eventually disappearing into the Rann of Kutch during the dry season.

Damodar River is historically called the 'Sorrow of Bengal' due to its frequent devastating floods that caused widespread damage in the region. The river flows through Jharkhand and West Bengal states. Major flood control measures like the Damodar Valley Corporation were later established to manage its waters.
