CIVIL ENGINEERING DEPARTMENT, NARULA INSTITUTE OF TECHNOLOGY, 81 NILGUNJ ROAD, AGARPARA, KOLKATA - 700109 2 Newsletter, Issue 1, 10th April 2010 10 Tallest Dams in the World The following list contains the 10 tallest dams in the world. Other methods of comparing dams is by their volume or by the volume of the reservoir they create. 1. Nurek Dam, Tajikistan – 300 m (980 ft). The tallest dam in the world, located on the Vakhsh River is an earth fill embankment dam. Construction of the dam began in 1961 and was completed in 1980 2. Xiaowan Dam, China – 292 m (958 ft). An arch dam on the Lancang (Mekong) River. The primary purpose of the dam is hydroelectric power generation and it supports a 4,200 MW power station. Constructed between 2002 and 2010, it is the world’s highest arch dam at 292 m (958 ft) 3. Grande Dixence Dam, Switzerland - 285 m (935 ft). A Concrete gravity on the Dixence River. At 285 m (935 ft) high, it is the tallest gravity dam in the world. Its primary purpose is hydroelectric power generation. The dam fuels four power stations, and generates enough to power 400,000 households 4. Inguri Dam, Georgia – 271.5 m (891 ft). A hydroelectric dam on the Inguri River in Georgia. The world’s second highest concrete arch dam 5. Vajont Dam, Italy – 261.6 m (858 ft). A disused dam, completed in 1959 in the valley of the Vajont River, 100 km north of Venice, Italy. A 1963 (9 October) landslide caused the overtopping of the dam and around 2,000 deaths. The overtopping was caused when the designers ignored the geological instability of Monte Toc on the southern side of the basin. Warning signs and negative appraisals during the early stages of filling were disregarded, and the attempt to safely control the landslide into the lake created a 200 metre tall wave (ten times higher than predicted) that brought massive flooding and destruction to the Piave valley below, wiping out several villages completely 6. Manuel Moreno Torres Dam, Mexico – 261 m (856 ft). An embankment dam and hydroelectric power station on the Grijalva River. After renovations, the hydroelectric power station is currently the largest in Mexico. The dam was designed in the early 1970s and constructed between 1974 and 1980 under topographical and geological constraints 7. Nuozhadu Dam, China – 261 m (856 ft). An embankment dam on the Lancang (Mekong) River. The dam creates a reservoir with a normal capacity of 21,749,000,000 m3 (17,632,000 acre•ft) at a level of 812 m (2,664 ft). The purpose of the dam is hydroelectric power production along with flood control and navigation 8. Tehri Dam, India – 260.5 m (855 ft). The highest dam in India. It is a multi-purpose rock and earth-fill embankment dam on the Bhagirathi River. Its main purpose is electricity generation and it withholds a reservoir for irrigation and municipal water supply 9. Mauvoisin Dam, Switzerland – 250 m (820 ft). A concrete arch dam across the Val de Bagnes. Initial construction on the dam commenced in 1951 and was completed in 1957, with the reservoir filling by 1958. In 1991, the dam was raised to increase the capacity of the reservoir for winter storage. The dam’s primary purpose is hydroelectric power generation 10. Laxiwa Dam, China – 250 m (820 ft). An arch dam on the Yellow River. The main purpose of the dam is hydroelectric power generation and has a capacity of 4,200 MW CIVIL ENGINEERING DEPARTMENT, NARULA INSTITUTE OF TECHNOLOGY, 81 NILGUNJ ROAD, AGARPARA, KOLKATA - 700109.

Received: 26 August 2011; in revised form: 10 September 2011 / Accepted: 14 September 2011 / Published: 22 September 2011 Abstract: The revitalization of the Rogun hydropower station project and launch of an Initial Public Offering has led the water-energy disputes between Tajikistan and Uzbekistan to a new stage. While two riparian states advocate their positions from their own perspective, it gives the impression of being a “prisoners’ dilemma” case from a regional cooperation point. This paper aims to review the decision of project revitalization from the unconventional security perspective, focusing mainly on its impact on Tajikistan. The scope will be limited to economic, energy, social and political security. The paper attempts to reveal the existing unconventional security threats and suggest possible solutions for the arising problems. Keywords: water-energy trade-off; unconventional security; opportunity costs; Tajikistan; Uzbekistan; Central Asia 1. Introduction How to adequately meet growing energy needs is a vital question for every nation.

  • Grande Dixence (2365 M) Where Nature and Hi-Tech Meet: Grande Dixence (2365 M)
    Wo sich Natur und Hi-Tech sich trifft: Grande Dixence (2365 m) Where nature and hi-tech meet: Grande Dixence (2365 m) Die Wasserkraft – The hydropower In der Schweiz wird die Stromerzeugung des Grundbedarfs durch die Atomkraft sichergestellt (40 % des Gesamtverbrauchs). Die Laufwasserkraftwerke sichern 25 % des Bedarfs. Die übrige Menge, fast ein Drittel des Verbrauchs, wird durch Speicherkraftwerke abgedeckt. The basic electricity production in Switzerland is provided by nuclear energy (40% of overall consumption). Run-of-river power stations provide 25 % of requirements. Almost one third of the consumption is provided through the hydroelectric power stations. Bereits 1922 setzte man in der Schweiz auf die Energieerzeugung durch Wasser. Der Kanton Wallis, ein Kanton, in dem 56 % der Gletscher des Landes liegen, war dafür ein idealer Stand- ort. 1929 begannen die Bauarbeiten für die erste Dixence-Staumauer. Die Arbeiten dauerten sechs Jahre. Nach nach dem Ende des Zweiten Weltkrieges stieg die Energienachfrage ständig an, der Damm erwies sich als zu klein. Im Jahr 1950 wurde mit dem Bau des neuen Dammes, der Grande Dixence begonnen. Die Bauarbeiten dauerten 15 Jahre, in denen abwechselnd 3'000 Arbeiter, meistens ausländische Gastarbeiter, während acht Monate des Jahres arbei- teten. Es wurde 6 Millionen Kubikmeter Beton verbaut. Mit der gleichen Menge Beton könnte man eine Mauer von 1,5 m Höhe und 10 Zentimeter Breite rund um die Erde auf der Höhe des Äquators bauen. Die Staumauer weist an ihrer Sohle eine Breite von 200 Metern aus. Die 700 Meter lange Krone der Staumauer verengt sich oben auf 15 Meter. Der Bau der Grande- Dixence gehört zu einem der kolossalsten, schwersten und eindrücklichsten Bauwerk der Alpen.
