The document summarizes India's river systems. It describes how rivers originate and flow through different stages from youthful to mature to older. It notes that India's river systems can be categorized as Himalayan or peninsular rivers. Himalayan rivers originate in the Himalayas and are longer and perennial, while peninsular rivers originate in the Deccan plateau and are shorter, drying up in summer. It provides details on the Indus river system, the longest in India, describing its source, tributaries, and flow through India and Pakistan before draining into the Arabian Sea. It mentions the Indus Waters Treaty between India and Pakistan that allocates water rights.

1. Class 9th
Chapter No 3
Drainge System of
India

2. Any Natural Stream Of water That flows in a channel
with defined banks, The river join by other streams
are generally called Tributaries. The River along with
all its tributaries from the River system..

3. How River affects
.
When a river along with its tributaries drains
an area, it affects the area in many ways
Vegetation, Agriculture Patterns Human
Settlements all can be affected by this.

4. Area Drained by river and its tributaries are known as
Drainage Basin.
Like Missipii in USA, the Nile in Africa, The Congo
Drainage basin in Africa. The Amazon Basin.
In India Ganga River forms the largest drainage
Basin. These drainage basin go through various
changes with the course of time due to some geological
events. Like the formations of Water Divide,.
Water divide an elevated area which separates two
drainage basins.

5. Rivers
The Life giving gift of nature to humans. Rivers
usually flow from a place that is relatively higher
altitude to a place having a lower altitude . The
Journery of river having 3 stage

6. The Youthful Stage
The Youthful Stage is dominated by vertical
erosion. Mostly erosion landforms are
crated in this stage. E.g Gorges, valley and
Waterfall are formed in this stage. The River
carries huge amount of sand and silt in this
stage.

7. Mature Stage or Middle Course.
IN This stage the stage of river flow is reduced in this
stage the in the youthful stage. Lateral erosion
dominates the mature stage and can be observed on
the sides of the river. Some erosional and
depositional landforms can be observed in this stage
e.g Oxbow lakes, meanders, flood plains are common
land forms in this stage.

8. Older Stage or Lower Course.
In this Stage the river flows very slowly and calmly.
Mainly deposition is observed in this stage. The Huge
amount of sand and silt carried by the rivers from the
upper course is deposited in this stage. Most of the
landform we found in this stage are depositional
landforms and deltas.

9. Older Stage or Lower Course.
In this Stage the river flows very slowly and calmly.
Mainly deposition is observed in this stage. The Huge
amount of sand and silt carried by the rivers from the
upper course is deposited in this stage. Most of the
landform we found in this stage are depositional
landforms and deltas.

10. INDIAN RIVER SYSTEM
Indian River System can be broadly categorized into

11. INDIAN RIVER SYSTEM
Himalayan Rivers Peninsular Rivers
Himalayan Rivers Originates
from the Himalayas
Peninsular Rivers Originates
from the Deccan Plateau
Most of the Himalayan Rivers
are very long
Most of the Peninsular Rivers
are shorter
Himalayan Rivers are
Perennial
Peninsular rivers dry up during
summer months
Himalayan rivers have a much
larger basins
Peninsular rivers have a smaller
basins

12. Indus River System
It is one of the longest rivers in the world and one
of the important River system in the world. This
river was home to one of the oldest civilization in
the world The Harappan civilization. That has a
history of more then 4500 years.

13. The Indus River system begin journey near Mansarovar lake
in Tibet in China the people identify the river as Sange
khumbad or lion mouth.

14. From Tibet it flows towards west the enter India
through Ladakh, there are some exquisite site of
the Gorge made by the Indus river along its
course in this region

15. The Zanskar , The Nubra The Hunza and the
Shayok are some of its tributaries that join the
Indus river from here the Indus river flows
through the region of Baltistan and Gilgit a
region in Paksitan.

16. Some other tributaries that Joins Indus are the
Satluj ,The Beas, The Ravi, The Chenab, and
the Jehlum all of them join together to enter the
river near in the city Mithonkot situated in
Pakistan the river then flows south and drains
into the Arabian sea.

17. This journey spanning at about 2900 Kms. One third of the river located in
India and rest in Pakistan, so this is the journey of the river Indus that starts
from Tibet and end in Arabian sea.

18. The river has been also a source of conflict between India and Pakistan as
there were shared by both the countries there has been some disagreement
between the two countries about how to get how much water so to solve this
issue the Indus river water treaty as sign Ed in 1960 known as Indus water
treaty 1960 that really gives the water of the Western river that is in the Jhelum
and the janab to Pakistan and those of the east river the Ravi beas and Sutlej to
India consequently India can use 20% of the total water of Indus River system
and use this river in the irrigation work in Punjab Haryana and Rajasthan
