The rivers of India play an important role in the lives of the Indian people. The river systems provide irrigation, potable water, cheap transportation, electricity, as well as provide livelihoods for a large number of people all over the country. This easily explains why nearly all the major cities of India are located by the banks of river. The rivers also have an important role in Hindu mythology and are considered holy by all Hindus in the country.
Seven major rivers (Indus, Brahmaputra, Narmada, Tapi, Godavari,
Krishna and Mahanadi )along with their numerous tributaries make up the river
system of India. Most of the rivers pour their waters into the Bay of Bengal.
Some of the rivers whose courses take them through the western part of the
country and towards the east of the state of Himachal Pradesh empty into the
Arabian Sea. Parts of Ladakh, northern parts of the Aravalli range and the arid
parts of the Thar Desert have inland drainage.
The rivers of India can be classified on the basis of origin and
on the type of basin that they form.
On the basis of origin :
·
Himalayan Rivers
·
Peninsular Rivers.
Himalayan Rivers
The main Himalayan river systems are the Ganga, the Indus and the
Brahmaputra river systems. The Himalayan rivers form large basins. Many rivers
pass through the Himalayas. These deep valleys with steep rock sides were
formed by the down - cutting of the river during the period of the Himalayan
uplift. They perform intense erosional activity up the streams and carry huge
load of sand and silt. In the plains, they form large meanders, and a variety
of depositional features like flood plains, river cliffs and levees. These
rivers are perennial as they get water from the rainfall as well as the melting
of ice. Nearly all of them create huge plains and are navigable over long
distances of their course. These rivers are also harnessed in their upstream
catchment area to generate hydroelectricity.
Peninsular Rivers
The main peninsular river systems include the Narmada, the Tapi,
the Godavari, the Krishna, the Kaveri and the Mahanadi river systems. The
Peninsular rivers flow through shallow valleys. A large number of them are
seasonal as their flow is dependent on rainfall. The intensity of erosional
activities is also comparatively low because of the gentler slope. The hard
rock bed and lack of silt and sand does not allow any significant meandering.
Many rivers therefore have straight and linear courses. These rivers provide
huge opportunities for hydro-electric power.
The Indus River
System
The Indus originates in the northern slopes of the Kailash range
in Tibet near Lake Manasarovar. It follows a north-westerly course through
Tibet. It enters Indian territory in Jammu and Kashmir.
It forms a picturesque gorge in this part. Several tributaries -
the Zaskar, the Shyok, the Nubra and the Hunza join it in the Kashmir region.
It flows through the regions of Ladakh, Baltistan and Gilgit and runs between
the Ladakh Range and the Zaskar Range. It crosses the Himalayas through a 5181
m deep gorge near Attock, lying north of the Nanga Parbat and later takes a
bend to the south west direction before entering Pakistan. It has a large
number of tributaries in both India and Pakistan and has a total length of
about 2897 km from the source to the point near Karachi where it falls into the
Arabian Sea. The main tributaries of the Indus in India are Jhelum, Chenab,
Ravi, Beas and Sutlej.
Jhelum
The Jhelum originates in the south-eastern part of Kashmir, in a
spring at Verinag. It flows into the Wular Lake, which lies to the north, and
then into Baramula. Between Baramula and Muzaffarabad it enters a deep gorge
cut by the river in the Pir Panjal range. It has a right bank tributary the
Kishanganga which joins it at Muzaffarabad. It follows the Indo-Pakistan border
flowing into the plains of Punjab, finally joining the Chenab at Trimmu.
Chenab
The Chenab originates from the confluence of two rivers, the
Chandra and the Bhaga,which themselves originate from either side
of the Bara Lacha Pass in Lahul. It is also known as the Chandrabhaga in
Himachal Pradesh. It runs parallel to the Pir Panjal Range in the
north-westerly direction, and cuts through the range near Kishtwar. It enters
the plains of Punjab near Akhnur and is later joined by the Jhelum. It is
further joined by the Ravi and the Sutlej in Pakistan.
Ravi
The Ravi originates near the Rotang pass in the Kangra Himalayas
and follows a north-westerly course. It turns to the south-west, near
Dalhousie, and then cuts a gorge in the Dhaola Dhar range entering the Punjab
plain near Madhopur. It flows as a part of the Indo-Pakistan border for some
distance before entering Pakistan and joining the Chenab river. The total
length of the river is about 720 km.
Beas
The Beas originates in Beas Kund, lying near the Rohtang pass. It
runs past Manali and Kulu, where its beautiful valley is known as the Kulu
valley. It first follows a north-west path from the town of Mandi and later a
westerly path, before entering the Punjab plains near Mirthal. It joins the
Sutlej river near Harika, after being joined by a few tributaries. The total
length of the river is 615 km.
Sutlej
The Sutlej originates from the Rakas Lake, which is connected to
the Manasarovar lake by a stream, in Tibet. Its flows in a north-westerly
direction and enters Himachal Pradesh at the Shipki Pass, where it is joined by
the Spiti river. It cuts deep gorges in the ranges of the Himalayas, and
finally enters the Punjab plain after cutting a gorge in a hill range, the
Naina Devi Dhar, where the Bhakra Dam having a large reservoir of water, called
the Gobind Sagar, has been constructed. It turns west below Rupar and is later
joined by the Beas. It enters Pakistan near Sulemanki, and is later joined by
the Chenab. It has a total length of almost 1500 km.
The Brahmaputra River System
The Brahmaputra originates in the Mansarovar lake, also the source
of the Indus and the Satluj. It is slightly longer than the Indus, but most of
its course lies outside India. It flows eastward, parallel to the Himalayas.
Reaching Namcha Barwa (7757 m), it takes a U-turn around it and enters India in
Arunachal Pradesh and known as dihang. The undercutting done by this river is
of the order of 5500 metres. In India, it flows through Arunachal Pradesh and
Assam, and is joined by several tributaries.
In Tibet, the river is known as the Tsangpo. There, it receives
less volume of water and has less silt. But in India, it passes through a
region of heavy rainfall and as such, the river carries a large amount of
rainfall and considerable amount of silt. The Brahmaputra has a braided channel
throughout most of its length in Assam, with a few large islands within the
channel.
The shifting of the channels of the river is also very common. The
fury of the river during rains is very high. It is known for creating havoc in
Assam and Bangladesh. At the same time, quite a few big pockets suffer from
drought.
The Narmada River System
The Narmada or Nerbudda is a river in central India. It forms the
traditional boundary between North India and South India, and is a total of
1,289 km (801 mi) long. Of the major rivers of peninsular India, only the
Narmada, the Tapti and the Mahi run from east to west. It rises on the summit
of Amarkantak Hill in Madhya Pradesh state, and for the first 320 kilometres
(200 miles) of its course winds among the Mandla Hills, which form the head of
the Satpura Range; then at Jabalpur, passing through the 'Marble Rocks', it
enters the Narmada Valley between the Vindhya and Satpura ranges, and pursues a
direct westerly course to the Gulf of Cambay. Its total length through the
states of Madhya Pradesh, Maharashtra, and Gujarat amounts to 1312 kilometres
(815 miles), and it empties into the Arabian Sea in the Bharuch district of
Gujarat.
The Tapi River System
The Tapi is a river of central India. It is one of the major
rivers of peninsular India with the length of around 724 km, and only the Tapi
River along with the Narmada river, and the Mahi River run from east to west.
It rises in the eastern Satpura Range of southern Madhya Pradesh state, and
flows westward, draining Madhya Pradesh's historic Nimar region, Maharashtra's
historic Khandesh and east Vidarbha regions in the northwest corner of the
Deccan Plateau and South Gujarat before emptying into the Gulf of Cambay of the
Arabian Sea, in the State of Gujarat. The Western Ghats or Sahyadri range
starts south of the Tapti River near the border of Gujarat and Maharashtra.
The Tapi River Basin lies mostly in northern and eastern districts
Maharashtra state viz, Amravati, Akola, Buldhana, Washim, Jalgaon, Dhule,
Nandurbar, Malegaon, Nashik districts but also covers Betul, Burhanpur
districts of Madhya Pradesh and Surat district in Gujarat as well.The principal
tributaries of Tapi River are Purna River, Girna River, Panzara River, Waghur
River, Bori River and Aner River.
The Godavari River System
The river with second longest course within India, Godavari is
often referred to as the Vriddh (Old) Ganga or the Dakshin (South) Ganga. The
name may be apt in more ways than one, as the river follows the course of
Ganga's tragedy. The river is about 1,450 km (900 miles) long. It rises at
Trimbakeshwar, near Nasik and Mumbai (formerly Bombay) in Maharashtra around
380 km distance from the Arabian Sea, but flows southeast across south-central
India through the states of Madhya Pradesh, Karnataka, Orissa and Andhra
Pradesh, and empties into the Bay of Bengal. At Rajahmundry, 80 km from the
coast, the river splits into two streams thus forming a very fertile delta.
Like any other major rivers in India, the banks of this river also has many
pilgrimage sites, Nasik, Triyambak and Bhadrachalam, being the major ones. It
is a seasonal river, widened during the monsoons and dried during the summers.
Godavari river water is brownish. Some of its tributaries include Indravati
River, Pranahita (Combination of Penuganga and Warda), Manjira, Bindusara and
Sabari. Some important urban centers on its banks include Nasik, Bhadrachalam,
Rajahmundry and Narsapur. The Asia's largest rail-cum-road bridge on the river
Godavari linking Kovvur and Rajahmundry is considered to be an engineering
feat.
The Krishna River System
The Krishna is one of the longest rivers of India (about 1300 km
in length). It originates at Mahabaleswar in Maharashtra, passes through Sangli
and meets the sea in the Bay of Bengal at Hamasaladeevi in Andhra Pradesh. The
Krishna River flows through the states of Maharashtra, Karnataka and Andhra
Pradesh.The traditional source of the river is a spout from the mouth of a
statue of a cow in the ancient temple of Mahadev in Mahabaleshwar.
Its most important tributary is the Tungabhadra River, which
itself is formed by the Tunga and Bhadra rivers that originate in the Western
Ghats. Other tributaries include the Koyna, Bhima, Mallaprabha, Ghataprabha,
Yerla, Warna, Dindi, Musi and Dudhganga rivers.
The Kaveri River System
The Kaveri (also spelled Cauvery or Kavery) is one of the great
rivers of India and is considered sacred by the Hindus. This river is also
called Dakshin Ganga. The headwaters are in the Western Ghats range of
Karnataka state, and from Karnataka through Tamil Nadu. It empties into the Bay
of Bengal. Its waters have supported irrigated agriculture for centuries, and
the Kaveri has been the lifeblood of the ancient kingdoms and modern cities of
South India.
The source of the river is Talakaveri located in the Western Ghats
about 5,000 feet (1,500 m) above sea level. Talakaveri is a famous pligrimage
and tourist spot set amidst Bramahagiri Hills near Madikeri in Kodagu district
of Karnataka. Thousands of piligrims flock to the temple at the source of the
river especially on the specified day known as Tula sankramana when the river
water has been witnessed to gush out like a fountain at a predetermined time.
It flows generally south and east for around 765 km, emptying into the Bay of
Bengal through two principal mouths. Its basin is estimated to be 27,700 square
miles (71,700 km²), and it has many tributaries including Shimsha, Hemavati,
Arkavathy, Kapila, Honnuhole, Lakshmana Tirtha, Kabini, Lokapavani, Bhavani,
Noyyal and Famous Amaravati.
The Mahanadi River System
The Mahanadi is a river of eastern India. The Mahanadi rises in
the Satpura Range of central India, and flows east to the Bay of Bengal. The
Mahanadi drains most of the state of Chhattisgarh and much of Orissa and also
Jharkhand and Maharashtra. It has a length of about 860 km. Near the city
of Sambalpur, a large dam - the Hirakud Dam - is built on the river.
