3. Location
•UPPER INDUS PLAIN
•It stares from Jehlum and ends at Mitthan
kot.
•LOWER INDUS PLAIN
•While from Mitthan Kot to the sea is called
lower Indus Plain.

9. Hydrology of Upper Indus Plain
• The rivers of the Punjab (River Indus and its
tributaries) are the source of canal irrigation in
the Punjab.
•There exist a large network of perennial canals
ensuring irrigation water supply throughout the
year.
•These canals were taken out from barrages and
headworks.
• These development have taken place after 1960.
• After the Indus Water Treaty (1960), two large
dams, the Mangla Dam and Tarbela Dam were
built to store flood water during summer season
and to supply irrigation water during the winter
when the flow in the river is very low.

10. Hydrology of Upper Indus Plain
•Five barrages (Rasul Barrage, Marala Barrage,
Qadirabad Barrage, Trimmu Barrage and
Chashma Barrage) were built under this treaty.
• Eight Link Canals were built and two gated
siphons to transfer water from the three western
rivers to River Ravi and River Sutlej.
•The scheme proved very successful.
• Not only the amount of water for irrigation has
increased, but the area under cultivation has
also increased.

11. Hydrology of Upper Indus Plain
•Besides the perennial canals, thousands
of tubewells were installed after 1960.
• The tubewells supplement canal water
for irrigation and also help to control water
logging and salinity in the province.
•In this way the ground water resource
has been used for irrigation.

12. Flash Flood
•A sudden flood usually
caused by a very heavy
burst of rain is called Flash
Flood, in the Monsoon
season most frequently
come in upper Indus Plain.

14. Four IMPORTANT DOABS
•The four important Doabs of the Punjab i.e.
1)Chaj Doab,( it is between river Jhelum and river Chenab)
2) Rechna Doab( it is between river Chenab and
river Ravi)
3)Bari Doab. It is between river Sutlej and
river Ravi.
4)Sindh Sagar Doab:
it is between Indus and river jhelum and some
part of the river Chenab.
.5) Neli Bar in district Multan and

15. Suitible Natural Inputs
•This is the most productive area of the
Punjab plain.
• The land is flat and level and is suitable
for farming.
•The alluvial soil is fertile and supports
profitable agriculture.
•The climate suits both the summer and
winter crops.
• There is a good network of canals for
irrigation (Water).

17. Active flood Plain ?
•The narrow strip of land on
both sides of the rivers is
called Active Flood Plain. It is
locally known as bet or
Khaddar land. Active flood
plains are in large number.
Both sides of the river Indus
and its tributaries.

18. Old Flood Plain
•Meander and cover flood plains cover
the area between the alluvial terraces
and the active flood plains.
•They are only flooded when there is
heavy monsoon rainfall.
•Old flood plains are in large
number.
• Both sides of the river Indus and
its tributaries.
Dr. Zafar Iqbal, PhD,

19. Meanders
•A winding curve, bend or loop
along the course of a stream
or river.
•Countless meanders of the all
five rivers are there.
Dr. Zafar Iqbal, PhD,
[email protected]

20. River Terrace
•A raised flat Area running
along and parallels to valley
walls. It is a part of a former
flood plain, left behind as river
cut down through the valley
flood are also found in upper
indus plain.

21. Oxbow Lakes
•Some where in the upper Indus Plain
these are seen due to changing the river
course.
Dr. Zafar Iqbal, PhD,
[email protected]

22. Piedmont Plains
•Piedmont Plains and alluvial fans are also
found in both sides of the river indus.
•These are formed due to slow pressure of
water in the upper indus plain where
heavy material is not carry out by the
water, so it deposits and makes piedmont
plain and alluvial fanses.

23. Soil of the Upper Indus Plain
•Alluvial Soil is there in the upper Indus
plain that is the best soil of the Pakistan
for the agriculture.
•It is fertile and suits for the crops.

24. Economic Activities in Upper Indus
Plain
•This is a very productive region and has
attracted large population.
• Density of population in Punjab is very high
due to same reason.
•Good agricultural production has attracted
large population.
•It has resulted in a large number of collecting
and distributing centers i.e. commercial towns
which have gradually developed into important
industrial centers

25. Why the large quantity of silt carried by
rivers in the Upper Indus Plain?
•Large rivers carry a large amount of silt.
This is the result of erosive work of the
rivers in the mountains where the river
erodes its bed and banks.
• The quantity of silt increases during the
floods because of the increase in volume
of water

29. Hydrology of Lower Indus Plain
•Only river Indus flows.
•River Indus flows into the Arabian Sea
south of Thatta through its distributaries
which flow across the delta.
•Width of the River Indus is 1.6km
•River Indus is in lower course
•Deposition is the main function of the
River Indus.
•No Doab is there.

30. Geographical Features
•Meander,
• ox-bow lakes,
• braided channels levees are present.
•Alluvial terraces or bars do not exist as
the Indus flows alone.
•Piedmont Plain with alluvial fans to the
west.

33. Population of Lower Indus Plain
•In Lower Indus plain the road network is
thick near river Indus on both sides of
the river.
•Away from river Indus there is thin
population and density of road network is
also thin.
•Ideal for agriculture with irrigation.

34. Cities in Lower Indus Plain
•Karachi and Hyderabad are the biggest
cities of the lower Indus Plain.
•Urban areas has dense population.
•Rural area is less populated.
•Great contrast can be seen here between
the difference of rich and poor or Urban
and rural area.

35. Sea Breeze
•There in the coastline up to 180km sea
breeze remains moderate the
temperature.
•Upper part of the Lower Indus Plan is
hotter than the lower part due to sea
breeze.
•Average rainfall of the lower Indus plain is
25mm

36. UPPER INDUS PLAIN LOWER INDUS PLAIN
Located in the northern
part of the Indus plain.
Located in the southern

River Indus and its major
tributaries flow here.
The River Indus flows
alone.
The Jehlum,Ravi and
Sutluj have joined the
Chanab at Panjnad to join
ti Indus River near
Mithankot.
River Indus flows into the
Arabian Sea south of
Thatta through its
distributaries which flow
which flow across the
delta
The average width of the
Indus is 1.4 km till Kalabagh
and 1.6km at Sukkur
Width of the River Indus
is 1.6km

37. UPPER INDUS PLAIN LOWER INDUS PLAIN
River Indus is in its
middle course in the north
And enters in its lower
course.
River Indus is in lower
course
Both erosion and
deposition take place with
deposition becoming
increasingly dominant
southward.
Deposition is the main
function of the River
Indus.
Meander, ox-bow lakes,
braided channels levees
are present.
