Indian Rivers and Waterways

The Volga River is the longest river in Europe and flows into the Caspian Sea, which is actually an inland lake (the largest inland body of water on Earth). It does not flow into any of the other seas listed. The White Sea, Baltic Sea, and Sea of Azov are all incorrect destinations for the Volga.

Goa's capital Panaji is situated on the banks of the Mandovi River, which is one of the major rivers flowing through the state. The Ganga flows through the plains of north India, Gomati is a tributary of Ganga in Uttar Pradesh, and Sabarmati is in Gujarat.

The Beas River rises in the Rohtang Pass in the Kullu district of Himachal Pradesh. Chambal rises in Madhya Pradesh, Tapti in central India, and Narmada also in central India - none originate in the Himalayas or Rohtang Pass.

The Subarnarekha River flows through Jamshedpur in Jharkhand. Godavari flows through central and southern India, Luni is in Rajasthan, and Krishna flows through Maharashtra and the southern states - none passes through Jamshedpur.

Wular Lake in Jammu and Kashmir is India's largest freshwater lake. Dal Lake is also in Kashmir but is much smaller, Powai Lake is an artificial lake in Mumbai, and Chilka Lake is a brackish water lagoon in Odisha - not freshwater.

Shivasamudram Falls is formed by the Cauvery River in Karnataka's Mandya district. It is famous for being the site of India's first hydroelectric power station established in 1902. The other rivers - Mahanadi, Sipra, and Ganga - flow through different regions.

Mahanadi River originates in the Sihawa mountains of northern Chhattisgarh, near Dhamtari. It flows through Odisha and into the Bay of Bengal. Sindhu (Indus) originates in Tibet, Tapti in Satpura range (MP), and Yamuna in Yamunotri Glacier (Uttarakhand).

Narmada River originates from Amarkantak plateau in the Maikal range of Madhya Pradesh. It is one of the few major rivers that flows westward into the Arabian Sea. Sangam is a confluence point (not a river), Satluj originates in Mansarovar (Tibet), and Mahanadi originates in Chhattisgarh.

Mahanadi flows through Chhattisgarh and Odisha (formerly Orissa) before emptying into the Bay of Bengal near Cuttack. Narmada and Tapti flow west into the Arabian Sea. Brahmaputra flows through Assam and Bangladesh into the Bay of Bengal but not through Odisha.

Hatnur Dam is built across the Tapti River in Jalgaon district of Maharashtra. It is one of the major dams on the Tapti. Narmada dams include Sardar Sarovar, while Brahmaputra dams are in Arunachal/Assam. Sindhu (Indus) dams are in Jammu & Kashmir.

Satluj River crosses three major Himalayan ranges: Zanskar, Great Himalayan, and Dhauladhar as it flows from Tibet into India. Ganges and Yamuna originate and flow through the Lesser Himalayas/Shiwaliks without crossing these three specific ranges. Brahmaputra crosses the Himalayas but via a different route in Arunachal.

Among the options, Kaveri is the shortest by length (~805 km). Krishna (~1400 km), Narmada (~1312 km), and Mahanadi (~900 km) are all longer. However, 'smallest' is ambiguous - it could mean length, discharge, or basin area. Assuming length, Kaveri is correct.

Gaumukh (Gomukh) is the source of the Bhagirathi River, which is the main headstream of the Ganges. It is located in the Uttarkashi district of Uttarakhand in the Gangotri Glacier. Brahmaputra originates in Tibet (Angsi Glacier), Sindhu in Tibet (near Mansarovar), and Yamuna in Yamunotri Glacier.

Satluj River originates near Lake Mansarovar in Tibet (China) at an elevation of about 4,600 meters. It enters India through Shipki La in Himachal Pradesh. Sangam is a confluence, Tapti originates in MP, and Sindhu originates near Mansarovar but is a different river.
