DRAINAGE
TOPICS
• DRAINAGE BASIN
• DRAINAGE SYSTEM IN INDIA
• HIMALAYAN RIVERS
• PENINSULAR RIVERS
The area drained by a single river system is
called a drainage basin.
DRAINAGE SYSTEMS IN
INDIAThe drainage systems of India are mainly controlled by the
broad relief features of the subcontinent.
Accordingly, the Indian rivers are divided in to two major
groups:
The Himalayan rivers.
The Peninsular rivers.
Comparison between the Himalayan &
Peninsular RiversHimalayan Rivers Peninsular Rivers
I. These rivers originate from the glaciers.
II. Catchment area is very large.
III. Engaged in high erosion activity.
IV. Useful in irrigation
V. Perennial.
VI. Eg.:- Indus, Ganga.
I. These rivers originate from
the plateaus.
II. Catchment area is very
small.
III. Engaged in low erosion
activity.
IV. Not very useful in
irrigation
V. Non-perennial.

Benefits of a River a) The rivers contain fresh water which is most necessary for
man as well as animals for survival.
b) They provide water for irrigation and cultivation available
in abundance.
c) They make the soil rich in Alluvial.
d) These serve as arteries of commerce.
e) They are good for navigation.
f) Estuaries, near the shores , where the sweet water mixes
freely with the salt water of the oceans, have proved to be
the most biologically productive areas of the world . All
type of fishes survive over here.
g) Rivers are harnessed for generation of hydro-electricity.
