The Idukki Dam, Kerala, India
The Idukki Dam, located in Kerala, India, is a 555 foot 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 is built on the Periyar River, in the ravine between the Kuravan and Kurathi Hills in Kerala, India. At 167.68 metres, the Idukki dam is one of the highest dams inthe world and the first arch dam in India. It started generating power on 4 October 1975.

Technically, the dam type is a concrete double, curvature parabolic, thin arc dam.


This dam was constructed along with two other dams at Cheruthony and Kulamavu. Together, the three dams have created an artificial lake that is 60 kmē in area. The stored water is used to produce electricity at the Moolamattom Power house, which is located inside nearby rocky caves. The Government of Canada aided in the building of the dam with long term loans and grants.


The Idukki Hydro Electric Project is a Collection of some 20 Small and Big Dams, 5 Rivers, a  Handful of Underground Tunnels and a Final Under ground Power Generator.
It is the biggest hydrolectricProject in Kerala (India). The three big dams are at Idukki,Cheruthony and Kulamavu. The power house atMoolamattom  is the longestunderground power station in India and the pressure shaft is thelargest in the country.  Cheruthony is thelargest and highest gravity dam in Kerala.


Idukki is about 100 Kilometers away from Cochin and is very easy to reach. There are buses very frequently and so it is very Easy to reach.

Dear Dr.N.Subramani,

Can you say that the Idukki dam is safe against earth quake resistant as per the present codal provisions.

I had visited the dam under construction during my engineering college studies as a study tour in the early years of 1960s. Hence this dam may be as old as 45 to 50 years of life.

Any retro fit is required?

As per the latest studies and reports  idukky dam is capable of storing the entire water from Mullaperiyar. How far it could be correct?

Best Wishes,
francis

Dear  SEFI  Enrs.
We Civil Engineers do amazing structures.  Here are examples of amazing Underground Structures (Tunnels). I am proud to be a Civil Engineer. Who else but us, Civil Engineers can do such projects.

A look at 8 huge tunnels under construction in the U.S.
Eight massive tunnels are currently being built in the U.S., including the13-mile-long Anacostia River Tunnel that is part of the Clean Rivers Project in Washington, D.C., and the 60-mile-long, 43-years-in-the-making City WaterTunnel No. 3 in New York. This article gives a brief description of each of the tunnels and includes photos.
