Q1Which river is called Dakshin Ganga and is described as the largest Peninsular river system?
Godavari, Krishna, Mahanadi and Cauvery are grouped among the major east-flowing Peninsular rivers. Within that group, Godavari is singled out as the largest Peninsular river system and is often called Dakshin Ganga because of its length, basin spread and cultural importance. Krishna, Mahanadi and Cauvery are also important, but their note-cues are different: Krishna has Bhima and Tungabhadra, Mahanadi has Hirakud, and Cauvery has Talakaveri and the Tamil Nadu delta.
Q2Consider the following statements about the Brahmaputra system. Statement 1: In Tibet, the river is known as Yarlung Tsangpo. Statement 2: In Arunachal Pradesh, it is known as Siang or Dihang. Statement 3: In Assam, it is known as Indus after receiving major eastern Himalayan tributaries. Which of the statements are correct?
There is a clear name sequence for the Brahmaputra. In Tibet, it is Yarlung Tsangpo. After entering Arunachal Pradesh, it is known as Siang or Dihang. In Assam, after receiving major eastern Himalayan tributaries, it is called Brahmaputra and is linked with a broad, flood-prone valley. The statement that it becomes Indus in Assam is the error, because Indus belongs to the north-western river system, not the north-east Brahmaputra system.
Q3Which of the following statements about Peninsular drainage is incorrect?
The incorrect statement transfers Tapi's source to Narmada. Narmada rises near Amarkantak and flows west through a rift valley between the Vindhyan and Satpura scarps into the Gulf of Khambhat. Tapi rises near Multai and also flows west towards the Arabian Sea. Godavari's largest Peninsular basin status, Mahanadi's Chhattisgarh-Odisha-Bay of Bengal course and the qualified delta pattern for east-flowing rivers are all correct.
Q4Assertion (A): Narmada and Tapi are standard west-flowing exceptions among major Peninsular rivers. Reason (R): Narmada flows through a rift valley between the Vindhyan and Satpura ranges towards the Gulf of Khambhat, and Tapi also flows westward.
Most large Peninsular rivers flow east into the Bay of Bengal because the plateau slopes broadly eastward. Narmada and Tapi are the standard exceptions. Narmada rises near Amarkantak and follows a rift valley between the Vindhyan and Satpura ranges towards the Gulf of Khambhat. Tapi rises near Multai and also flows westward. Since the reason gives the structural and direction-based basis for the exception, both statements are true and the reason explains the assertion.
Q5Assertion (A): The Water Act, 1974 declared 111 national waterways, including NW-1 on the Ganga-Bhagirathi-Hooghly system and NW-2 on the Brahmaputra. Reason (R): The National Waterways Act, 2016 declared 111 national waterways and connects rivers with inland transport. Choose the correct answer.
The assertion deliberately mixes two different legal points. The Water Act, 1974 is linked with water pollution control for rivers, lakes and other water bodies. It did not declare 111 national waterways. The National Waterways Act, 2016 declared 111 national waterways, including NW-1 on the Ganga-Bhagirathi-Hooghly system and NW-2 on the Brahmaputra. Therefore the statement about the Water Act is false, while the reason about the 2016 Act is true.
