Indian Rivers and Waterways

Antecedent drainage refers to a river that has maintained its course and direction despite the rise of mountain ranges around it. The Brahmaputra flows northward through the Himalayas (which rose later), meaning it predates the main Himalayan orogeny and has an antecedent drainage pattern with its watershed north of the main range.

The Farakka Barrage is a dam built on the Hugli River (also spelled Hooghly), which is a distributary of the Ganga. It is located near the Bangladesh border and was built to divert water from the Ganga to the Hugli River to maintain its flow and prevent siltation.

The Ganga is characterized by being a braided river with multiple channels and intertwined sand-bars, and it deposits enormous sediment into the Bay of Bengal. However, gully erosion is not a characteristic feature of the Ganga. Gully erosion typically occurs in smaller streams in upper reaches, not in major mature rivers like the Ganga in its middle and lower courses.

The Ganga has a larger delta than the Indus because the Indus flows mostly through arid and semi-arid regions (Thar Desert area) where it receives little water from tributaries along its path. In contrast, the Ganga flows through humid, monsoon-dominated regions and receives numerous tributaries, collecting significantly more water and sediment to form a massive delta.

Mettur Dam is built across the Kaveri.

Option (3) is not correctly matched.

The Trans-Himalayan region refers to the area north of the Himalayan ranges, including the Tibetan Plateau. Rivers like Sutlej, Indus (Sindh), and Brahmaputra originate in this region (near Mansarovar/Kailash). The Ganga, however, originates from the Gangotri glacier in the Greater Himalayas (Garhwal region), not in the Trans-Himalayan zone.

Option (3) is the correct answer. 

Narmada, Tapti, and Damodar all flow through rift valleys formed by tectonic activity. Kaveri flows through regular river valleys in the Deccan Plateau, not a rift valley.

India have two inland rivers: (1) Luni River (Rajasthan); (2) Saraswati River (Gujarat).

The Ganga is navigable from Allahabad (where it's joined by the Yamuna) all the way to Haldia on the Bay of Bengal. This lower stretch is deep and wide enough for boats and ships.

Tehri Dam is constructed in Uttarakhand on the river Bhagirathi.

The Chambal River is famous for its extensive ravine system in the Chambal Valley. These deep gullies and badlands were formed by centuries of erosion in the soft alluvial soil.

Seven major rivers along with their numerous tributaries make up the river system of India.

Indravati River is a tributary of the Godavari River. It originates in Odisha and flows through Chhattisgarh before joining the Godavari near the border of Maharashtra and Telangana.
