Indian Rivers and Waterways

This is the correct answer. The Tapi is a peninsular river that flows West and makes an estuary.

The Indus rises in Tibet, near Lake Mansarowar. Flowing West, it enters India in the Ladakh district of Jammu and Kashmir.

This is the correct answer. The Dhuadhar falls are located on the Narmada.

This is the correct answer as the Brahmaputra has a braided channel in its entire length in Assam and forms many riverine islands.

The Godavari is the largest peninsular river. This is the correct answer.

This is the correct answer. The Amravati, the Bhavani, the Hemavati and the Kabini are tributaries of the Kaveri.

This is the correct answer. Both statements a and b are correct.

The Limpopo crosses the Tropic of Capricorn twice. It separates South Africa from Botswana and Zimbabwe.

The Ganges-Brahmaputra Delta (also known as the Sundarbans Delta) is the world's largest river delta, formed by the confluence of the Ganges and Brahmaputra rivers. It covers approximately 105,000 square kilometers and spans across Bangladesh and India. The Seine-Rhine forms a smaller European delta, the Danube flows into the Black Sea, and while the Nile forms a large delta, it is formed by a single river, not a pair.

Both statements are factually incorrect. India has approximately 14,500 km of navigable waterways (not 16,500 km as stated). The Inland Waterways Authority of India (IWAI) was established in 1986, not 1996.

National Waterway 1 (NW-1) runs between Allahabad (Prayagraj) and Haldia on the Ganga River, spanning approximately 1,620 km, making it India's longest national waterway. This was the first national waterway declared in India and remains the most significant inland water transport route. The Sadiya-Dhubri stretch (NW-2) on Brahmaputra is the second longest but shorter than NW-1.

The Jhelum River is the primary river that flows through the Kashmir Valley. It originates from Verinag Spring in Anantnag district and flows through Srinagar before entering Pakistan-administered Kashmir. The Chenab, Ravi, and Beas flow through other regions of Punjab and Himachal Pradesh but not through Kashmir Valley.

The North Indian plains were formed by alluvial deposition (sedimentation) carried down by the Himalayan rivers over millions of years. The Indus, Ganga, and Brahmaputra river systems transported enormous amounts of silt, sand, and clay from the mountains, depositing them in the vast foreland basin. Erosion and denudation are processes that remove material, not build plains.

The Damodar basin is called the 'Ruhr of India' because, like Germany's Ruhr Valley, it has rich coal deposits and is heavily industrialized. The basin contains numerous coal fields and supports major industries.
