Azhutha Dam
Azhutha Dam (Malayalam:അഴുത അണക്കെട്ട്) is a small diversion dam built on the Azhutha river which is a tributary of the Pamba River, at Azhutha in Peerumed Grama Panchayat of Idukki District, Kerala, India. It is a small concrete gravity dam that is only long and high. It acts mainly as a diversion dam to supply water to the Idukki Dam. Azhutha dam is constructed as an augmentation dam for the Idukki Hydro Electric Project. Construction of the project started in 1987 and was expected to be commissioned in 1991. But the project overrun and was only partially commissioned in June 1998. The year of completion was 2007. The release of the water from the dam is to Azhutha river and it flows through Ranni and Ayroor Ayroor (also spelled Ayiroor) is a village Near Thiruvalla,located in the western part of Ranni taluk, in the Pathanamthitta district in Kerala state, India. It is bordered by hills and located near the Western Ghats. Ayroor was prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Azhutha River
Azhuthayar is a tributary of the Pamba River, the third longest river in the South Indian state of Kerala. It originates from Peerumedu, flows through dense forests and reaches Koruthodu. From there it forms the boundary between Kottayam and Idukki districts. It then crosses Sabarimala traditional trekking path at Kalaketti area before joining with Pamba river at Kanamala(Pambavalley). Like its parent river, it is also closely related to the legend of Lord Ayyappan, a popular Hindu deity worshipped mainly in Kerala. It flows through a place also named Azhutha (near Kalaketti Temple), which is on the Sabarimala trek route from Erumeli to Sabarimala. The river Pamba, ultimately flows around through towns and villages Ranni, Cherukolpuzha, Kozhencherry, Maramon, Aranmula, Chengannur, Parumala, Neerettupuram, Kavalam, Nedumudi and Thakazhy before joining Vembanad lake Vembanad is the longest lake in India, as well as the largest lake in the state of Kerala.

Kerala
Kerala ( ; ) is a state on the Malabar Coast of India. It was formed on 1 November 1956, following the passage of the States Reorganisation Act, by combining Malayalam-speaking regions of the erstwhile regions of Cochin, Malabar, South Canara, and Thiruvithamkoor. Spread over , Kerala is the 21st largest Indian state by area. It is bordered by Karnataka to the north and northeast, Tamil Nadu to the east and south, and the Lakshadweep Sea to the west. With 33 million inhabitants as per the 2011 census, Kerala is the 13th-largest Indian state by population. It is divided into 14 districts with the capital being Thiruvananthapuram. Malayalam is the most widely spoken language and is also the official language of the state. The Chera dynasty was the first prominent kingdom based in Kerala. The Ay kingdom in the deep south and the Ezhimala kingdom in the north formed the other kingdoms in the early years of the Common Era (CE). The region had been a prominent spic ...

India
India, officially the Republic of India (Hindi: ), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country, and the most populous democracy in the world. Bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast, it shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the north; and Bangladesh and Myanmar to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives; its Andaman and Nicobar Islands share a maritime border with Thailand, Myanmar, and Indonesia.

Concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most widely used building material. Its usage worldwide, ton for ton, is twice that of steel, wood, plastics, and aluminum combined. Globally, the ready-mix concrete industry, the largest segment of the concrete market, is projected to exceed $600 billion in revenue by 2025. This widespread use results in a number of environmental impacts. Most notably, the production process for cement produces large volumes of greenhouse gas emissions, leading to net 8% of global emissions. Other environmental concerns include widespread illegal sand mining, impacts on the surrounding environment such as increased surface runoff or urban heat island effect, and potential public health implications from toxic ingredients. Significant research and development is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravity Dam
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Diversion Dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an onground or groundwater reservoir or a storm drain. An early diversion dam is the Ancient Egyptian Sadd el-Kafara Dam at Wadi Al-Garawi, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and 87 metres wide. It was destroyed by a flood while it was still under construction.Günther Garbrecht: "Wasserspeicher (Talsperren) in der Antike", ''Antike Welt'', 2nd special edition: ''Antiker Wasserbau'' (1986), pp.51-64 (52f.)

Idukki Dam
The Idukki Dam is a double curvature arch dam constructed across the Periyar River in a narrow gorge between two granite hills locally known as '' Kuravan'' and ''Kurathi'' in Idukki, Kerala, India. At , it is one of the highest arch dams in Asia. It is constructed and owned by the Kerala State Electricity Board. It supports a 780 MW hydroelectric power station in Moolamattom, which started generating power on 4 October 1975. The dam type is a concrete, double curvature parabolic, thin arc dam. The Indo-Canadian project was inaugurated by the Prime Minister Indira Gandhi on February 17, 1976. This dam was constructed along with two other dams at Cheruthoni and Kulamavu. Together, the three dams and Two saddle dams, Kulamavu Saddle Dam (Near Junction) and Kulamavu Saddle Dam (Right Bank) have created an artificial lake that is in area. The stored water is used to produce electricity at the Moolamattom Power house, which is located inside nearby rocky caves. Narakakkanam, A ...
