Frequently Asked Questions
What is the difference between a river basin and a watershed?
A river basin is a large area drained by a major river and all its tributaries, whereas a watershed is a smaller ridge or boundary separating distinct drainage basins.
Why are Peninsular rivers seasonal while Himalayan rivers are perennial?
Himalayan rivers are fed by both melting glaciers and monsoon rains, making them perennial. Peninsular rivers depend entirely on seasonal monsoon rainfall, causing them to shrink or dry up during summer.
Which major rivers flow through Telangana?
The Godavari and the Krishna are the two major river systems flowing through Telangana, along with several of their tributaries like the Manair, Pranhita, and Tungabhadra.
