1.2. INTRODUCTION
The State of Maharashtra was forme d on 1st May 1960. The movement
by Sanyukta Maharashtra Samiti led to the division of the Bombay State
into Gujarat (speaking Gujarati and Kutchhi) and Maharashtra (speaking
Marathi and Konkani through Bombay Reorganisation Act, 1960 enacted
by the Parliam ent of In dia on 25 April 1960. The act came into effect on 1
May 1960. Mumbai is the Capital of the state and financial capital of the
country as it contributes to the highest revenue earning deposits to the
country. Presently the state has 36 districts as Palghar has been formed as
the new district of the state carved out from Thane district on 01st August
2014.
* Location and Size:
i) The absolute location is given with reference to latitude and longitude
extent of any area. Thus the absolute latitudinal and longitud inal extent is
15044 t o 2 206 north latitudes and 72036 to 80054 east longitudes of
Maharashtra State.
ii) Relative location is explained with reference to its neighbouring area in
different directions. Thus state of Maharashtra is confined with lan d
boundar ies of Madhya Pradesh to its north, Chhattisgarh to its east,
Telangana to its south east, Karnataka to its south, Goa to its south west
and, the natural water front boundary of Arabian Sea to west, Dadra and
Nagar Haveli (union territories) and G ujarat state to its north -west
iii) Size: Size is explained with reference to its total area and extent.
Thus total area of Maharashtra state is 3, 07,690 square kilometres ( sq.km ).
Its length (north -south extent) is 720 km. and its bread th (east -west
extent) is 800 km. Its total coastline along Arabian Sea is 720 km.
while its land boundary with all the neighbouring state is km. When
compared with the share of its land and population to India it is 9.36 %
of land area and 9.29% s hare of p opulation (2011 Census). It is the
third largest state in terms of land area and second largest populated
state of the country.
1.3. SUBJECT DISCUSSION
Relief features also play an important role in determining the
climate and drainage system of a region. The consolidated interaction
effect of these elements get reflected and recognised in its landscape cover
of varied natural vegetation in a region. munotes.in

Features, Rivers and
Climate
3 The State of Maharashtra is bestowed with great relief features ranging
from mountain and hills; pe aks and c liffs; ghats and valleys; plateaus;
river and coastal plains; beaches and creeks. Its drainage system in the form
of large rivers with its tributaries and rivulets; springs, ponds and lakes
provide with fresh water resources. The state has tropica l monsoon
climate with seasonal rains as heavy as over 400 cm in some regions.
Warm summer starts from March onwards up to late October, while
winters are mild. Let us discuss these above mentioned aspects in detail as
under:
1.4. MAHARASHTRA RELIEF
5.4.1. Introduct ion: Physiographically the state of Maharashtra largely
comprises of three broad divisions:
a) The Mountain range of Sahyadri’s or Western Ghats
b) The Plateau region of Deccan
c) The Coastal Plain of Konkan
a) The Mountain range of Sahyadri’s or Wester n Ghats: is the
mountainous faulted and eroded edge of the Deccan Plateau. The average
elevation in this mountain is 1000 to 1200 meters above mean sea level.
The Sahyadri mountain range runs parallel to the Arabian seacoast. There
are many offshoots branc hing east wards from the main Sahyadri ranges
such as Satmala, Ajanta, Harishchandra, Balaghat and Mahadeo hills.
Its highest peak is Kalsubai at an altitude of 1650 meter. Most of the
rivers in Maharashtra originate in the Sahyadri that forms the water -
divide to produce eastward and westward flowing rivers. These ranges
are also characterised by a number of ghats (passes), the important
ones being Thal, Bor, Kumbharli, Amba, Phonda and; Amboli from
transport view point since ancient times.

Geography of Maharashtra
4 b) The Plateau region of Deccan: In the north the plateau is flanked
by Satpura ranges, which run in the East -West direction in Maharashtra. It
is important to note that a large area of Maharashtra state is a
highland of Deccan plateau form ed by the volcanic activity and the
subsequent cooling down of the lava. The rocks are of igneous type
mainly basalt and granite. The altitude of the plateau varies from 450 to
750 meters. Important cities of this region are Pune, Nagpur and Solapur.
c) The C oastal Pl ain of Konkan: Konkan coastal region is a narrow
plain that stretches from the states of Gujarat to Kerala lying to the west
between the Arabian Sea and the western ghats of the Sahyadri range. This
coastal strip is barely 50 km in width which is wider in the north and
narrows down to the south. The coastline is dissected by the branches of
Sahyadri’s and wave -cut platforms that form river creeks up to the
coast.
The Konkan coastal plains of the State extend from Daman in the
north to the Terekhol creek in the south for about 750 km to the west
of Sahyadri.
The important creeks in Konkan from north to south are
Vaitarna, Thane, Dharamtar, Dabhol, Rajapuri, Vijaydurg and
Terekhol.
The Konkan coastal districts of Maharashtra are Palghar,
Thane, Greate r Mumbai, Raigad, Ratnagiri and Sindhudurg.
Konkan coastal lowland is just 20 to 40 km in width in the southern
districts of Ratnagiri and Sindhudurg districts. While the northern
districts of Thane and Palghar have relatively wider coastal lowland
with 80 to 100 k m. width. The relief of this lowland is dominated
and interspersed with numerous scattered low hills.
Greater Mumbai is an island with Salsette largely coalesced by
reclaiming the low -lying area of the sea.
The Konkan coastal region is marked by h illy and narrow valleys,
highly dissected with transverse ridges of the Western Ghats and
at many places extending as promontories, notches, sea caves,
embayment, submerged shoals and offshore islands. munotes.in

1.5. MAJOR R IVERS AND RIVER SYSTEM OF
MAHARASHTRA
1.5.1. Drainage system: Tapi, Godavari, Bhima and Krishna are the main
rivers of the state. About 75% area of Maharashtra is drained by
eastward gently flowing rivers of the Godavari and Krishna into the
Bay o f Bengal. Other 25% area is drained by westward flowing rivers
of Narmada and Tapi ; and short -swift flowing Konkan Rivers rising
from cliffs of Sahyadri viz: Ulhas, Savitri, Vashishthi and Shastri
flowing into the Arabian Sea.
The rivers of Konkan rise fr om the cl iffs of Sahyadri and have a short
swift flow into the Arabian Sea. Some important rivers are Ulhas, Savitri,
Vashishthi and Shastri. munotes.in

Geography of Maharashtra
6 Climatically the State of Maharashtra overall enjoys tropical monsoon
type of climate which is hot and humid for m ost part of the year.
Maharashtra receives its rainfall mainly from south -west monsoon.
The rainfall in state varies considerably with as heavy as over 400 cm in
some regions. There is heavy rainfall in the coastal region, scanty rains in
rain shadow areas in the c entral part and moderate rains in eastern parts of
the state. The state however experiences four seasons:
i) The Summer season from March to May
ii) The rainy season from June to September
iii) The Post monsoon season from October to November iii) The Wi nter
season from December to February
1.4.3 Physiographically this state may be divided into three natural
divisions –
1. the coastal strip (the Konkan), consists undulating low lands.
2. the Sahyadri or the Western Ghats, running almost parallel to the sea
coast.
3. a. the plateau
b. The Shambhu Mahadeo, Harischandra -Balaghat and Ajanta Satmal
mountain ranges, again divide Deccan plateau region into three
subdivisions separating:
Krishna basin
Bhima basin
Godavari basin
Tapi-Purna basin
1.4.4. The major relief f eatures o f Maharashtra are as follows: 1. The
Sahyadri Range:
The Western Ghats of Maharashtra known as the ‘Sahyadri’ mountain
ranges have an average elevation of 1000 -1200 m above the MSL.
It extends from near the Tapi mouth to much further beyond the southern
limits of the state.
The Sahyadri hills run southwards, parallel to the seacoast, with many
offshoots branching eastwards from the main ranges, for example,
Satmala, Ajanta, Harishchandra, Balaghat and Mahadeo.
The slopes of the Sahyadri gently des cend towa rds the east and south -
east.
The Western Ghats are not true mountains, but are the faulted edge of
the Deccan plateau and are believed to have been formed during the munotes.in

7 break -up of the super continent of Gondwana some 150 million years
(mya) ago.
The special features are the hills of Trimbakeshwar, Matheran and the
Mahableshwar plateau.
Its highest peak is Kalsubai at an altitude of 1650 m., near Igatpuri. The
other important peak is Salher (1567 m) situated about 90 km north of
Nasik.
A number of spurs and ri dges shoot off to the west and descend down
to the sea often forming rocky headlands and promontories jutting into
the sea.
Most of the rivers in Maharashtra originate in the Sahyadri and then
divide to join the eastward and westward flowing river s.
These ranges are also characterised by a number of ghats, the
important ones being Thal, Bor, Kumbharli, Amba, Phonda and Amboli.
The Ghats are a succession of steep hills, periodically bisected by narrow
roads. Most of the famous hill stations of the s tate are at the Ghats.
The Western Ghats form one of the three important watersheds of
India, from which many South Indian rivers originate, like Godavari,
Bhima, Koyna and Krishna.

9 2. Maharashtra Plateau:
Other than the Western Ghats and the Konkan coast, the remaining
portion of Maharashtra is a land of the high plateau of the Deccan,
having a latitudinal and longit udinal ex tension of 15° 44 -21° 40' N
and 73° 15' - 80° 33' E respectively.
This region includes the entire state of Maharashtra except the Konkan
coast and the Sahyadris.
It starts form the Sahyadri ranges in the west and slopes gradually
east wards to Nagp ur.
It is separated from the Konkan coastline by 'Ghats'.
From the east of Sayadris, hills like Satmal, Ajanta,
Harishchandra, Balaghat and Mahadeo stretch across the Maharashtra
Plateau towards east with a decreasing height in the same direction.
Between these ran ges lie the valleys of Godavari, Bhima and Krishna
rivers.
The plateau is therefore divided into different units such as the
i. Ajanta hills the Godavari valley
ii. The Balag hat plateau the Bhima basin.
iii. The Mahadeo uplands and the Krishna basin.
In the nort h the plateau is flanked by Satpura ranges, which run in the
East-West direction in Maharashtra.
The river Narmada flows along the north boundary of
Maharashtra, and other major rivers like Krishna, Godavari, Bhima,
Penganga -Wardha, and Tapi -Purna h a v e c a r ved the plateau in
alternating broad river valleys and intervening highlands.
The plateau character and the topography, which is a dominant physical
trait of the state, owe its origin to the cooling down of the lava during
the periods of volcanic activity.
Much of the region except the eastern part of Wardha Wainganga basin
and a small littoral patch in Ratnagiri is underlain by basaltic rocks
of the Deccan Trap.
Important ridges on Plateau:
The Mahadeo range branches off from the main ridge at abo ut 18o N
and runs towards south east.
Another ridge named Harishchandra Ghat lies in its western part while
Balaghat range in the east.
These ridges are characterised by extensive plateaus on their top. munotes.in
Page 10
Geography of Maharashtra
10 The Mahabaleswar and Panchgani Plateau lie on the Mah adeo Hills
whereas Ahmadnagar Plateau lies on the Balaghat range.
Further north of the Harishchandra Ghat range, from west to east runs
a series of detached hill masses known as the Ajanta range. At its eastern
extremes this ridge has again divided itself into two spurs. The southern
one passing through the Parbhani and Nanded districts called the Nirmal
range. The northern one passing through the Yavatmal district is known as
the Satmal range.
On the top of the Ajanta -Satmal range lies the Buldhana plateau of
weste rn Vidharbha and Malegaon plateau closer to Sahyadri range.
Although the Satpura range lies mostly outside the northern limits of
the state its sharp crested ridge occurs in the west in Dhule district and
as Gawilgad hills in the northern part of Am ravati .
Toranmal is a small plateau which rises to 1 150m.
The highest peak is Astamba Donger 1325m. It overlooks the Tapi
valley.
The southern slopes of these ranges fall abruptly from the height of
about 1200 m. To below 300 m.
The cliffs run in ENE d irection.
The linear trend of the scarp face indicates that faulting was partly
responsible for the formation of this scarp.
1.5. THE DRAINAGE SYSTEM OF MAHARASHTRA
Maharashtra’s topography is traversed by river systems draining as far
as to the Bay of Ben gal Sea i n the east and as short and swift flowing
rivers to the west into the Arabian Sea.
