Indian Rivers and Waterways

Bhakra-Nangal (Bhakhara Nagal) is considered the biggest multipurpose project in India. Built across the Satluj River, it provides irrigation to millions of hectares, generates significant hydropower, and offers flood control benefits.

The region north and east of the Ganga basin experiences very high rainfall, has undulating terrain, and canal construction is expensive there. All these factors make canal irrigation less viable compared to tube wells or other methods.

Sindhu was the old name of the river Indus and Vitasta was the old name of the river Jhelum.

Hirakud Dam, built across the Mahanadi River in Odisha, is one of the longest dams in the world. It was constructed for flood control, irrigation, and hydroelectric power generation, and it forms one of the largest artificial lakes in Asia.

The phrase "a major source of water" is an appositive that correctly describes the Ganges using the singular form "source" to match the singular subject. "The most major" and "a more major" are incorrect because "major" doesn't form comparatives with more/most.

The seven sacred rivers of India (Ganga, Yamuna, Godavari, Sarasvati, Narmada, Sindhu, and Kaveri) are collectively referred to as 'Sapta Teertha' in Hindu tradition, meaning 'seven holy places' or 'seven sacred fords'. In Hinduism, rivers are considered teerthas (sacred pilgrimage sites). 'Saptavahini' refers to something else, 'Saptasindhu' refers to the Indus region, and 'Saptakshetra' means 'seven sacred places/cities'.

All the river-site associations are correct: Mohenjodaro is on the Indus, Chanhudaro is on the Indus/Sutlej region, and Harappa is on the Ravi. Since all specific matches are accurate, option D ('None' meaning 'none of the above is incorrect') is the correct answer.

The Indus, Beas, Chenab, and Sutlej (Satlez) are all rivers associated with the Indus Valley Civilization region. The Mahanadi is a major river in eastern India (Odisha and Chhattisgarh) that flows into the Bay of Bengal, completely outside the IVC geographical area.

The 1998 China floods were catastrophic, affecting over 240 million people. The Yangtze (Changjiang) and Songhua rivers overflowed. Wait - Hwang Ho is the Yellow River, which did flood in 1998 but the Yangtze was the primary disaster. The question asks for maximum havoc - Yangtze and Hwang Ho together (Option D) caused the worst damage. The 1998 floods were centered on the Yangtze basin.

The Ganga delta (specifically the Hooghly-Matla region in West Bengal) is the major jute-producing area in India. This region has ideal conditions for jute cultivation - fertile alluvial soil, high humidity, and adequate rainfall. While jute is also grown in the Brahmaputra delta (Assam), the Ganga delta accounts for the maximum cultivation. Mahanadi and Godavari deltas are not major jute-producing regions.

Cauvery is a river of Southern India. It rises from Brahmagiri Hill in Western Ghats in Coorg district of Karnataka.

The correct sequence of the rivers in India moving from North towards South is Shyok — Zaskar — Spiti — Sutlej. Shyok flows through Northern Ladakh in India. Zaskar river flows in the North-Eastern part of Ladakh. Spiti river is situated at Kaza in Himachal Pradesh at an elevation of 12,500 feet. Sutlej river rises from the slopes of Kailash and flows in the South-West direction to Himachal Pradesh and Punjab.

The Narmada originates from a tank 1057 m high, West of Amarkantak plateau in Madhya Pradesh. The Damodar originates from Chhota Nagpur plateau. The Mahanadi originates from Bastar plateau and the Tapi originates from Satpura hills.
