Drainage system in India
The drainage systems of India are mainly controlled by the broad relief features of the subcontinent. Accordingly, the Indian rivers are divided into two major groups:
 * The Himalayan rivers; and
 * The peninsular rivers

The Himalayan rivers
The major Himalayan rivers are the Indus, the Ganga and the Brahmaputra. These rivers are long., and are joined by many large and important tributaries., A river alongwith its tributaries may be called a river system.

The Indus River
The river Indus rises in Tibet, near Lake Mansarowar. Flowing west, it enters India in the Ladakh district of Jammu and Kashmir. The Indus flows through Baltistan adn Giligit and emerges from the mountains at Attock. The Satluj, the Beas, the Ravi, the Chenab and the Jhelum join together to enter the Indus near Milthankot in Pakista. Beyond this, the Indus flows southwards eventually reaching the Arabian Sea, east of Karachi. The Indus plain has a very gentle slop. With a total length of 2900km.

The Ganga River
The headwaters of the Ganga, called the 'Bhagirathi' is fed by the Gangotri Glacier and joined by the Alaknanda at Devaprayag in Uttarakhand. At Haridwar the Ganga emerges from the mountains on to the plains.

The Ganga is joined by many tributaries from the Himalayas, a few of them being major rivers such as te Yamuna, the Ghaghara,m the Gandak and Kosi.

The main tributaries, which come from the peninsular uplands, are the Chambal, the Betwa and the Son.

The Brahmaputra River
The Brahmaputra rises in Tibet east of Mansarowar lake very close to the sources of the Indus and the Satluj. It is slightly longer than the Indus, and most of its course lies outside India. It flows eastwards parallel to the Himalayas. On reaching the Namcha Barwa (7757), it takes a 'U' turn and enters India in Arunachal Pradesh through a gorge. Here, it is called the Dihang and it is joined by the Dibang, the Lohit, and many other tributaries to form the Brahmaputra in Assam at last drains into Bay of Bengal.

The Narmada Basin
The Narmada rises in the Amarkantak hills in Madhya Pradesh. It flows towards the west in a rift valley formed due to faulting. On its way to the sea,. the Narmada flows through a dep grge, and the 'Dhuadhar falls' where the river plunges over steep rocks, are some of the notable ones. All the tributaries of the Narmada are very short and most of these join the main stream at right angle.The Narmada basin covers parts of Madhya Pradesh and Gujarat.

The Mahanadi Basin
The Mahanadi rises in the highlands of Chhattisgarh. It flows through Odisha to reach the Bay of Bengal. The length of the river is about 860km. Its drainage basin is shared by Maharashtra, Chhattisgarh, Jharkhand, and Odisha.

The Krishna Basin
Rising from a spring near Mahabaleshwar, Krishna flows for about 1400 km and reaches the Bay of Bengal. The Tungabhadra, the Koyana, the Ghatprabha, the Musi and the Bhima are some of its tributaries. Its drainage basin is shared by Maharasthra, Karnataka and Andhra Pradesh.

There are many other Peninsular rivers are there in India.
