Q169. Which is the largest peninsular river system?
[WBCS Mains (2022)]
(A) Godavari
(B) Narmada
(C) Cauvery
(D) Mahanadi
Answer: (A) Godavari
Explanation: The Godavari has the largest drainage basin among peninsular rivers. It rises near Trimbakeshwar in Maharashtra and drains the Deccan eastwards into the Bay of Bengal. Plateau slopes and underlying geological structures are especially important in determining peninsular drainage patterns.
Q168. Which is India’s longest west-flowing peninsular river?
[WBCS Mains (2022)]
(A) Tapi
(B) Luni
(C) Narmada
(D) Bhagirathi
Answer: (C) Narmada
Explanation: The Narmada stretches from the Amarkantak highlands to the Gulf of Khambhat. At roughly 1,300 kilometres, it exceeds other important west-flowing peninsular rivers in length. Plateau slopes and underlying geological structures are especially important in determining peninsular drainage patterns.
Q167. Where does the Godavari River originate?
[WBCS Mains (2022)]
(A) Amarkantak
(B) Nilgiri Hills
(C) Sihawa
(D) Trimbak
Answer: (D) Trimbak
Explanation: The Godavari rises at Trimbakeshwar near Nashik in the Western Ghats of Maharashtra. It then flows eastwards across the peninsula and reaches the Bay of Bengal. Plateau slopes and underlying geological structures are especially important in determining peninsular drainage patterns.
Q166. Which of these is India’s longest dam?
[WBCS Mains (2022)]
(A) Bhakra Nangal
(B) Rihand
(C) Hirakud
(D) Nagarjuna Sagar
Answer: (C) Hirakud
Explanation: The Hirakud project on the Mahanadi in Odisha is famous for its very long embankment and associated dykes. It was designed for flood moderation, irrigation and electricity. Reservoir location, river discharge and terrain affect the supply of water for irrigation and electricity.
Q165. Barakar is a tributary of which river?
[WBCS Mains (2022)]
(A) Mahanadi
(B) Ganga
(C) Damodar
(D) Ajay
Answer: (C) Damodar
Explanation: The Barakar flows through the Jharkhand–West Bengal region and joins the Damodar. Reservoirs in the Damodar Valley Corporation network help regulate its waters. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q164. The Nagarjuna Sagar multipurpose project lies across which two states?
[WBCS Mains (2022)]
(A) Telangana and Andhra Pradesh
(B) Tamil Nadu and Andhra Pradesh
(C) Karnataka and Tamil Nadu
(D) Kerala and Karnataka
Answer: (A) Telangana and Andhra Pradesh
Explanation: The Krishna River forms the border near Nagarjuna Sagar between Telangana and Andhra Pradesh. The reservoir supports large canal networks and hydroelectricity in this region. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q163. On which river is the island of Majuli located?
[WBCS Mains (2022)]
(A) Brahmaputra
(B) Ganga
(C) Cauvery
(D) Mahanadi
Answer: (A) Brahmaputra
Explanation: Majuli lies among shifting Brahmaputra channels in Assam. Deposition, bank erosion and periodic flooding have continually altered the island’s area and landscape. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
Q162. Sardar Sarovar hydroelectric project is associated with which river?
[WBCS Mains (2022)]
(A) Sutlej
(B) Bhagirathi
(C) Narmada
(D) Rihand
Answer: (C) Narmada
Explanation: The Sardar Sarovar project harnesses the Narmada in Gujarat. Its canal and power systems provide water and electricity to adjoining areas of western India. Reservoir location, river discharge and terrain affect the supply of water for irrigation and electricity.
Q161. Which river marks part of the Rajasthan–Madhya Pradesh boundary?
[WBCS Mains (2022)]
(A) Yamuna
(B) Gomti
(C) Ken
(D) Chambal
Answer: (D) Chambal
Explanation: The Chambal flows through and along the borders of Madhya Pradesh and Rajasthan before joining the Yamuna. Its valley is also well known for extensive ravine erosion. Regional relief, river outlets and tributary connections help distinguish the surrounding drainage basin geographically.
