Drainage Systems in India
Flow of water from a higher to a lower level is called drainage. It also refers to the river system of any particular area.
The Indian River system is divided into two groups- the Himalayan Rivers and the
Peninsular Rivers.
The Himalayan Rivers
They have water all throughout the year and originate from the mountains in the north. They flow through the mountains and form gorges.
Himalayan rivers cover long routes before falling into the sea.
Erosion activities in the upper courses. Hence, they bring loads of sand and silt on their way down and deposit it in the lower courses.
In the middle and lower courses, these rivers form meanders, oxbow lakes and deltas.
The Peninsular Rivers
Seasonal rivers i.e. they depends on rainfall.
They have short courses as compared to the Himalayan Rivers.
They flow through the plateaus and low hills and hence, they are not as fast flowing as the Himalayan rivers.
The Himalayan Rivers
The Indus River System
Originates from Lake Mansarovar in Tibet and enters India through Ladakh in
Jammu and Kashmir.
The Zaskar, the Nubhra, the Shyok and the Hunza join the Indus in Kashmir.
The Satluj, the Ravi, the Chenab, the Beas and the Jhelum together join Indus at
Mithankot in Pakistan. Indus merges with the Arabian Sea near Karachi in
Pakistan.
Length is 2900 km. It is one of the longest rivers in the world.
The Ganga River System
The Ganga originates from the Gangotri Glacier in Uttarakhand in the form of
Bhagirathi river.
The Bhagirathi and the Alaknanda rivers join together at Devprayag and form the Ganga river.
The Ganga enters the plains at Haridwar in Uttarakhand.
Major tributaries of the Ganga are the Yamuna, the Ghaghara, the Gandak and the Kosi.
The Yamuna originates from the Yamunotri Glacier in the Himalayas and joins
Ganga at Allahabad.
The Kosi, the Ghaghara and the Gandak originate from the Nepal Himalayas.
