Hailed
as the "Temples of Resurgent India" by Pandit Jawaharlal Nehru, the
country's dams help provide water and electricity to millions citizens.
We look at some of the biggest ones.
The Tehri Dam is a multi-purpose
rock and earth-fill embankment dam on the Bhagirathi River near Tehri
in Uttarakhand, India. It is the primary dam of the Tehri Hydro
Development Corporation Ltd. and the Tehri hydroelectric complex. The
dam is a 260 metres (850 ft) high rock and earth-fill embankment dam.
Its length is 575 metres (1,886 ft), crest width 20 metres (66 ft), and
base width 1,128 metres (3,701 ft).
Kerala
Government has long been demanding construction of a new dam in
Mullaperiyar on the Kerala-Tamil Nadu border. Many believe that the
existing 116-year-old dam could pose safety hazard.
While the matter rests with the apex court, we look at some of
India’s biggest and most famous dams, hailed by Pandit Jawaharlal Nehru
as ‘The Temples of a Resurgent India
Bhakra Dam is a concrete gravity
dam across the Sutlej River, and is near the border between Punjab and
Himachal Pradesh in northern India.
The dam, located at a gorge near the (now submerged) upstream Bhakra
village in Bilaspur district of Himachal Pradesh, is Asia's second
highest at 225.55 m (740 ft) high next to the 261m Tehri Dam. The length
of the dam (measured from the road above it) is 518.25 m; it is 9.1 m
broad. Its reservoir, known as the "Gobind Sagar", stores up to 9.34
billion cubic meters of water, enough to drain the whole of Chandigarh,
parts of Haryana, Punjab and Delhi.The 90 km long reservoir created by
the Bhakra Dam is spread over an area of 168.35 km2. In terms of storage
of water, it withholds the second largest reservoir in India, the first
being Indira Sagar dam in Madhya Pradesh with capacity of 12.22 billion
cu m.Nangal dam is another dam downstream of Bhakra dam.
Hirakud Dam is built across the
Mahanadi River, about 15 km from Sambalpur in the state of Orissa in
India. Built in 1957, the dam is one of the world's longest earthen dam.
Hirakud Dam is the longest man-made dam in the world, about 16 mi (26
km) in length. It is one of the first major multipurpose river valley
project started after India's independence.
Nagarjuna Sagar Dam is the
world's largest masonry dam built across Krishna River in Nagarjuna
Sagar, Nalgonda District of Andhra Pradesh, India, between 1955 and
1967. The dam contains the Nagarjuna Sagar reservoir with a capacity of
up to 11,472 million cubic metres. The dam is 490 ft (150 m). tall and
1.6 km long with 26 gates which are 42 ft (13 m). wide and 45 ft (14 m).
tall. Nagarjuna Sagar was the earliest in the series of large
infrastructure projects initiated for the Green Revolution in India; it
also is one of the earliest multi-purpose irrigation and hydro-electric
projects in India.
The Sardar Sarovar Dam is a
gravity dam on the Narmada River near Navagam, Gujarat, India. It is the
largest dam and part of the Narmada Valley Project, a large hydraulic
engineering project involving the construction of a series of large
irrigation and hydroelectric multi-purpose dams on the Narmada River.
The project took form in 1979 as part of a development scheme to
increase irrigation and produce hydroelectricity. It is the 30th
largest dams planned on river Narmada, Sardar Sarovar Dam (SSD) is the
largest structure to be built. It has a proposed final height of 163 m
(535 ft) from foundation. The dam is one of India's most controversial
dam projects and its environmental impact and net costs and benefits are
widely debated. The World Bank was initially a funder of the SSD, but
withdrew in 1994. The Narmada Dam has been the centre of controversy and
protest since the late 1980s
The
Indirasagar Dam is a multipurpose key project of Madhya Pradesh on the
Narmada River at Narmadanagar in the Khandwa district of Madhya Pradesh
in India. The Project envisages construction of a 92 m high and 653 m
long concrete gravity dam. It provides Irrigation in 1,230 square
kilometres of land with annual production of 2700 million units in the
districts of Khandwa and Khargone in Madhya Pradesh and power generation
of 1000 MW installed capacity (8x125). The reservoir of 12,200,000,000
m3 (9,890,701 acre•ft) was created. less
Tungabhadra Dam
The Bhavanisagar Dam and Reservoir, also called Lower Bhavani
Dam, is located on the Bhavani River between Mettupalayam and
Sathyamangalam in Erode District, Tamil Nadu, South India. The dam is
situated around 16 km (9.9 mi) west to Satyamangalam and 35 km (22 mi)
from Gobichettipalayam, 36 km (22 mi) north-east to Mettuppalayam and 70
km (43 mi) from Erode and 75 km (47 mi) from Coimbatore. The dam
is considered to be among the biggest earthen dams in the country.
Bhavani Sagar dam is constructed on Bhavani River, which is merely under
the union of Moyar River. The dam is used to divert water to the Lower
Bhavani Project Canal
The Koyna Hydroelectric Project
is the largest completed hydroelectric power plant of India It is a
complex project consisting of total four dams with the largest Dam built
on Koyna River known as Koyna Dam hence the name Koyna Hydroelectric
project. The total Installed capacity of the project is 1,920 MW. The
project consists of 4 stages of power generation. Due to the project's
electricity generating potential the Koyna River is considered as the
life line of Maharashtra.
The Idukki Dam, located in Kerala, India, is a 168.91 m (554 ft)
tall arch dam. The dam stands between the two mountains - Kuravanmala
(839) m and Kurathimala (925)m. It was constructed and is owned by the
Kerala State Electricity Board. It supports a 780 MW hydroelectric power
station.
It is built on the Periyar River, in the ravine between the Kuravan
and Kurathi Hills in Kerala, India. At 167.68 metres, it is one of the
highest arch dams in Asia and third tallest dam in India.
Krishna Raja Sagara, also
popularly known as KRS, is the name of both a lake and the dam that
causes it.Sir. Mokshagundam Visvesvarayya served as the chief engineer
during the construction of this dam. The dam is named for the then ruler
of the Mysore Kingdom, Krishnaraja Wodeyar IV
The Mettur Dam is a large dam in
India built in 1934.[1] It was constructed in a gorge, where the Kaveri
River enters the plains. The dam is one of the oldest in India. The
total length of the dam is 1,700 m (5,600 ft).
The Srisailam Dam is a dam
constructed across the Krishna River at Srisailam in the Kurnool
district in the state of Andhra Pradesh in India and is the second
largest capacity hydroelectric project in the country. The dam was
constructed in a deep gorge in the Nallamala Hills, 300 m (980 ft) above
sea level. It is 512 m (1,680 ft) long, 145 m (476 ft) high and has 12
radial crest gates. It has a reservoir of 800 km2 (310 sq mi).
The Banasura Sagar Dam is
located 21 km from Kalpetta, in Wayanad District of Kerala in the
Western Ghats. It is the largest earthen dam in India and the second
largest in Asia.
