The Tapti, also known as Tapti, is a major west-flowing river of Peninsular India, with a length of approximately 724 km. It originates near Multai in the Betul district of Madhya Pradesh and flows through Maharashtra and Gujarat before entering the Arabian Sea through the Gulf of Khambhat. The Purna and Girna are among its important tributaries. Like the Narmada, the Tapi flows westwards through a tectonically influenced valley. Ukai Dam in Gujarat is an important project associated with this river.
Which is the longest river in Peninsular India?
The Godavari is the longest river in Peninsular India, with a length of approximately 1,465 km. It originates at Trimbakeshwar in Maharashtra and flows towards the Bay of Bengal. The river is also called Dakshin Ganga because of its length, cultural significance and importance to southern India. The Krishna, Narmada, Kaveri and Tapi are other important rivers of Peninsular India.
Which is the largest river in India by water volume?
The Brahmaputra is generally recognised as one of India’s largest rivers by water discharge, carrying an exceptionally large volume of water through Northeast India. Its discharge is especially high during the monsoon season. The Ganga, although commonly identified as India’s longest river, has a different drainage pattern and flow characteristics. Candidates should remember that river length, drainage-basin area and water discharge are different measures and do not necessarily produce the same ranking.
What is the difference between Himalayan and Peninsular Rivers?
Himalayan and Peninsular rivers differ in their origin, flow patterns and water sources. Himalayan rivers generally receive water from both rainfall and snow or glacier melt, while most Peninsular rivers depend heavily on seasonal rainfall. The table below highlights the important differences.
| Feature | Himalayan Rivers | Peninsular Rivers |
|---|---|---|
| Origin | Himalayan and adjoining mountain regions | Peninsular plateaus and hill ranges |
| Water Source | Rainfall, snow and glacier melt | Primarily rainfall |
| Flow Nature | Generally perennial | Many show stronger seasonal variation |
| River Valleys | Often deep valleys in mountainous regions and broad floodplains downstream | Frequently flow through older, more stable landscapes |
| Examples | Ganga, Yamuna, Indus, Brahmaputra | Godavari, Krishna, Narmada, Kaveri, Tapi |
| Common Flow Direction | Depends on river system | Many flow east; major exceptions flow west |
Which important dams are built on the major rivers of India?
Several major dams and multipurpose projects have been constructed on Indian rivers for irrigation, hydropower generation, flood management and water supply. Knowledge of important dam-river pairs is useful for competitive examinations. The table below provides some examples.
| Dam/Project | River | State |
|---|---|---|
| Tehri Dam | Bhagirathi | Uttarakhand |
| Sardar Sarovar Dam | Narmada | Gujarat |
| Nagarjuna Sagar Dam | Krishna | Telangana–Andhra Pradesh border |
| Srisailam Dam | Krishna | Andhra Pradesh–Telangana region |
| Hirakud Dam | Mahanadi | Odisha |
| Ukai Dam | Tapi | Gujarat |
| Krishna Raja Sagara Dam | Kaveri | Karnataka |
| Jayakwadi Dam | Godavari | Maharashtra |
