THE INDIAN DESERT
On the basis of the orientation, the desert can
be divided into two parts
THE SOUTHERN TOWARDS THE RANN OF KACHCHH
THE NORTHERN PART SLOPING TOWARDS SINDH
with longitudinal dunes
and barchans
arid
climate with low vegetation cover
because
of these characteristic features that this is also known as Marusthali
land features
present here are mushroom rocks, shifting dunes and oasis
The Luni river
The lakes and the playas have brackish
water which is the main source of obtaining salt.
THE COASTAL PLAINS
On the basis of the location and
active geomorphological processes, it can be
broadly divided into two
THE EASTERN COASTAL PLAINS
WELL DEVELOPED DELTAS
the deltas of the Mahanadi, the
Godavari, the Krishna and the Kaveri
THE WESTERN COASTAL PLAINS
Kandla,
Mazagaon, JLN port Navha Sheva, Marmagao, Mangalore, Cochin, etc. are some of the
important natural ports
the Kachchh AND Kathiawar coast in Gujarat
Konkan coast in
Maharashtra
Goan coast and Malabar coast
in Karnataka and Kerala respectively
The Malabar
coast has got certain distinguishing features in the form of ‘Kayals’ (backwaters), which
are used for fishing, inland navigation and also due to its special attraction for tourists
Every
year the famous Nehru Trophy Vallamkali (boat race) is held in Punnamada Kayal in
Kerala.
THE ISLANDS
ISLANDS IN BAY OF BENGAL
consist of about 572 islands/islets
two principal groups of islets
the Ritchie’s archipelago
the Labrynth island
The entire group of island is divided into two broad categories
the
Andaman in the north
Nicobar in the
south.
They are separated by a waterbody
which is called the Ten degree channel
Barren island, the only active volcano in India
is also situated in the Nicobar islands.
IMPORTANT MOUNTAIN PEAKS
Saddle
peak (North Andaman – 738 m),

Geography_11_I-PE_Chapter 03: DRAINAGE SYSTEM
DRAINAGE BRIEF
The flow of water through well-defined channels is known as ‘drainage’
network of such channels is called a ‘drainage system’.
A river drains the water collected from a
specific area, which is called its ‘catchment area’.
An area drained by a river and its tributaries
is called a drainage basin.
Important Drainage Patterns
The drainage pattern resembling the branches of a tree is known as “dendritic”
When the rivers originate from a hill and flow in all directions, the drainage pattern is known
as ‘radial’
When the primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as ‘trellis’.
When the rivers discharge their waters from all directions in a lake or depression, the
pattern is know as ‘centripetal’.
The boundary line separating one drainage basin from the other is known as the watershed.
The catchments of large rivers are called river basins.
while those of small rivulets and rills are often referred to as watersheds
Watersheds are small in area while
the basins cover larger areas.
River basins and watersheds are marked
by unity. one part affects the other. They are accepted as the most appropriate micro,
meso or macro planning regions.
INDIAN DRAINAGE SYSTEM
ON THE BASIS OF ORIENTATION OF DISCHARGE OF WATER
THE BAY OF BENGAL DRAINAGE
Nearly 77 per cent of the drainage
area consisting of the Ganga, the Brahmaputra,
the Mahanadi, the Krishna, etc. is oriented
towards the Bay of Bengal
THE ARABIAN SEA DRAINAGE
23 per cent
comprising the Indus, the Narmada, the Tapi,
the Mahi and the Periyar systems discharge
their waters in the Arabian Sea.
ON THE BASIS OF SIZE OF WATERSHED
MAJOR RIVER BASINS WITH MORE THAN 20,000 SQ.KM OF CATCHMENT AREA
includes 14 drainage basins such as the
Ganga, the Brahmaputra, the Krishna, the Tapi, the Narmada, the Mahi, the Pennar, the Sabarmati, the Barak, etc.
MEDIUM RIVER BASINS WITH CATCHMENT AREA BETWEEN 2,000-20,000 SQ.KM
44 river basins such as the Kalindi, the Periyar,
the Meghna, etc.
MINOR RIVER BASINS WITH CATCHMENT AREA LESS THAN 2,000 SQ.KM
Large rivers flowing on the Peninsular plateau have their origin in the Western Ghats and discharge their waters in the Bay of Bengal. The Narmada and Tapi are two large rivers which are exceptions. They along with many small rivers discharge their waters in the Arabian Sea.
On the basis of the mode of origin, nature
and characteristics
DRAINAGE SYSTEMS OF INDIA
THE HIMALAYAN DRAINAGE
EVOLUTION OF HIMALAYAN DRAINAGE
in due course of time Indo– Brahma river was dismembered into three main drainage systems
the Indus and its five
tributaries in the western part
the Ganga and its Himalayan tributaries in the central part
the stretch of the Brahmaputra in Assam and its Himalayan tributaries in the eastern part
dismemberment was due to
Pleistocene upheaval in
the western Himalayas
uplift of the Potwar Plateau (Delhi Ridge)
the down- thrusting of the Malda gap area
Shiwalik or Indo-Brahma traversed from Assam
to Punjab and onwards to Sind & discharged into the Gulf of Sind 5-24 million years ago
THE RIVER SYSTEMS OF HIMALAYAN DRAINAGE
THE INDUS SYSTEM
one of the largest river basins of the world
covering an area of 11,65,000 sq. km (in India it is 321, 289 sq. km
total length of 2,880 km (in India 1,114 km)
Indus also known as the Sindhu
westernmost of the Himalayan rivers in India
originates from a glacier near Bokhar Chu in
the Kailash Mountain range
In Tibet, it is known as ‘Singi Khamban; or Lion’s mouth
Himalayan tributaries such as the Shyok, the Gilgit, the Zaskar, the Hunza, the Nubra, the Shigar, the Gasting and the Dras
it receives the Kabul river on its right bank
tributaries joining the right bank of the Indus
are the Khurram, the Tochi, the Gomal, the Viboa and the Sangar
river flows southward
and receives ‘Panjnad’
the Ravi
rises west of the Rohtang pass in
the Kullu hills of Himachal Pradesh
joining the Chenab near
Sarai Sidhu
the Beas
originating from the Beas Kund near
the Rohtang Pass
enters the Punjab plains where it meets the
Satluj near Harike.
the Satluj
Satluj originates in the ‘Raksas tal’ near
Mansarovar
in Tibet where it is known as Langchen Khambab
It passes through the Shipki
La on the Himalayan ranges
It is an antecedent river
very important tributary as it feeds the canal
system of the Bhakra Nangal project.
the Chenab
largest tributary of the Indus
formed by two streams, the
Chandra and the Bhaga
also known as Chandrabhaga
the Jhelum
rises from foot of the Pir Panjal
joins the Chenab near Jhang in Pakistan.
flows through
Srinagar and the Wular lake
finally discharges into the Arabian Sea, east of Karachi
Indus flows in India only through Jammu and
Kashmir.
THE BRAHMAPUTRA SYSTEM
one of the largest rivers
of the world
its origin in the Chemayungdung glacier of the Kailash range near the Mansarovar lake
traverses eastward longitudinally for a
distance of nearly 1,200 km in a dry and flat region of southern Tibet
In Tibet, it is known as the Tsangpo, which means ‘the purifier.
The Rango Tsangpo is the major
right bank tributary of this river in Tibet
The river emerges from the foothills under
the name of Siang or Dihang.
It enters India
west of Sadiya town in Arunachal Pradesh.
it receives its main left
bank tributaries, viz., Dibang or Sikang and Lohit
thereafter, it is known as the
Brahmaputra.
major left bank
tributaries are the Burhi Dihing and Dhansari
important right bank
tributaries are the Subansiri, Kameng, Manas and Sankosh
The Subansiri which has its
origin in Tibet, is an antecedent river.
In Bangladesh, the Tista joins it on its right bank from where the river is known as the Jamuna
finally merges with the river Padma, which falls in the
Bay of Bengal.
The Brahmaputra is well-known
for floods, channel shifting and bank erosion.
This is due to the fact that most of its tributaries
are large, and bring large quantity of sediments owing to heavy rainfall in its catchment area.
THE GANGA SYSTEM
Ganga basin covers about 8.6
lakh sq. km area in India alone
length of 2,525 km
split into two distributaries
the Padma
the Bhagirathi
At Devprayag, the Bhagirathi meets the Alaknanda, hereafter, it is known as the Ganga
Alkananda
tributaries of Alaknanda such as the Pindar joins it at Karna Prayag while Mandakini or Kali Ganga meets it at Rudra Prayag
Alaknanda consists of the Dhauli and the Vishnu Ganga
Alaknanda has its source in the Satopanth
glacier above Badrinath
it is known as the Bhagirathi
rises in the Gangotri glacier near Gaumukh in Uttarkashi district of Uttarakhand
The Son is its major right bank tributary
originating in the Amarkantak
plateau
it reaches Arrah, west
of Patna, to join the Ganga.
important left bank tributaries are the
Ramganga, the Gomati, the Ghaghara, the Gandak, the Kosi and the Mahananda.
The Gandak
comprises two streams
Kaligandak
Trishulganga
It enters the Ganga plain in
Champaran district of Bihar
joins the Ganga at Sonpur near Patna.
The Ghaghara
originates in the glaciers of Mapchachungo
its tributaries – Tila, Seti and Beri
The river Sarda (Kali or Kali Ganga) joins it in the plain
it finally meets the Ganga at Chhapra.
The Kosi
an antecedent river with its source to the north of Mount Everest in Tibet
joined by the Son Kosi from the West and the Tamur Kosi from the east
forms Sapt Kosi after uniting with the river Arun.
The Ramganga
a small river rising in the Garhwal hills near Gairsain
it joins the Ganga near Kannauj.
The Damodar
it flows through a rift valley and finally joins the Hugli
The Barakar is its main tributary
Once known
as the ‘sorrow of Bengal’
The Sarda or Saryu river
rises in the Milam
glacier in the Nepal Himalayas
where it is known as the Goriganga
Along the Indo-Nepal
border, it is called Kali or Chauk, where it joins the Ghaghara
The Mahananda
joins the Ganga as its last left bank
tributary in West Bengal.
rising in the Darjiling
hills
finally discharges itself into the Bay of
Bengal near the Sagar Island.
The Yamuna
the western most and the longest tributary of the Ganga
Source- Yamunotri glacier on the western slopes of Banderpunch range
joins the Ganga at Prayag (Allahabad)
it is joined by the Chambal, the Sind, the Betwa and the Ken on its right bank
The Chambal
rises near Mhow in the Malwa plateau of Madhya Pradesh
Gandhisagar dam has been constructed
The Chambal is famous for its badland topography called the Chambal ravines.
the Hindan, the Rind, the Sengar, the Varuna, etc. join it on its left bank
It mainly includes the Ganga, the Indus and the Brahmaputra river basins
