The longest river in the world is the Nile River, it reaches around 6650 kilometers in length (4132 miles).
The second longest river in the world is the Amazon River, it reaches around 6400 kilometres in length (4000 miles).
longest river in the USA is the Missouri River, stretching around
2,340 miles (3,770 km) in length (slightly longer than the Mississippi
River). The two combine to form the longest river system in North
America, reaching around 3902 miles in length (6275 km).
Small rivers often have different names which include creek, stream and brook.
Rivers normally contain freshwater.
word upriver (or upstream) refers to the direction of the river’s water
source, while downriver (or downstream) refers to the direction in
which the water flows, i.e. towards the end of the river.
Rivers have many uses which include fishing, bathing, transport, rafting and swimming among others.
Most of the world’s major cities are located near the banks of rivers.
The Ganges, Yangtze and Indus rivers are three of the most polluted on Earth.

Indian River Systems
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.
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.
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
The Indus River System
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.
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
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 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 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 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 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
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
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.
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
The Narmada River System
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
The Tapi River System
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.
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
The principal tributaries of Tapi River are Purna River, Girna River, Panzara River, Waghur River, Bori River and Aner River.
The Godavari River System
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
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.
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.
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
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.
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
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.
