Introduction:
India is a land of many rivers and mountains.
India’s geographical area of about 329 MHa is criss-
crossed by a large number rivers. Some of the Indian
rivers are figuring amongst the most notable rivers of
the world.
The rivers and mountains have a greater significance
in the history of Indian culture, economy,
development, religious and spiritual life.

It may not be an exaggeration to say that the rivers are
the heart and soul of Indian population.
The river systems provide water
For irrigation,
Drinking and domestic consumption,
cheap transportation,
generating electricity, and
for the livelihoods for a large number of people all
over the country.
Nearly most of the major cities of India are located by
the banks of the rivers.

The perennial rivers are considered as life supporting
resources by all the farmers in India.
Rivers are classified into major, medium and minor
types.
Most of these rivers pour their waters into the Bay of
Bengal, except some of the rivers whose courses take
them through the western part of the country
emptying the waters into the Arabian Sea.
Understanding the river basins of India is needed to
all geographers, administrators, planners and others.
