Kouhrang 1 Dam
The Kouhrang 1 Dam is a masonry gravity dam on the Kouhrang River about southwest of Chelgard in Chaharmahal and Bakhtiari Province, Iran. The primary purpose of the dam is to divert up to of water annually via the long Kouhrang 1 Tunnel to the Zayandeh River to the east where it would help supply cities like Isfahan with water. Since the era of Shah Abbas I, attempts had been made to diver the Kouhrang to the Zayandeh. Eventually, efforts by Alexander Gibb between 1948 and 1954 led to the completion of the Kouhrang 1 Dam and Tunnel.

Kouhrang 3 Dam
The Kouhrang 3 Dam (سد کوهرنگ ۳, also known as Birgan dam بیرگان) is an arch dam currently under construction on the Kouhrang River in Chaharmahal and Bakhtiari Province, Iran. It is located about northwest of Dashtak. The purpose of the dam is water supply and river regulation. Upstream of the dam will be the intake for the Kouhrang 3 Tunnel which will transfer water northeast to the Zayandeh River for use in major cities like Isfahan Isfahan ( fa, اصفهان, Esfahân ), from its Achaemenid empire, ancient designation ''Aspadana'' and, later, ''Spahan'' in Sassanian Empire, middle Persian, rendered in English as ''Ispahan'', is a major city in the Greater Isfahan Regio .... Sabir Co. was awarded the contract for the dam's construction in February 2011 and construction began that same year. The diversion tunnels for the dam were completed in March 2013.

Masonry Dams
Masonry is the building of structures from individual units, which are often laid in and bound together by mortar; the term ''masonry'' can also refer to the units themselves. The common materials of masonry construction are bricks, building stone such as marble, granite, and limestone, cast stone, concrete blocks, glass blocks, and adobe. Masonry is generally a highly durable form of construction. However, the materials used, the quality of the mortar and workmanship, and the pattern in which the units are assembled can substantially affect the durability of the overall masonry construction. A person who constructs masonry is called a mason or bricklayer. These are both classified as construction trades. Applications Masonry is commonly used for walls and buildings. Brick and concrete block are the most common types of masonry in use in industrialized nations and may be either load-bearing or non-load-bearing. Concrete blocks, especially those with hollow cores, offer vari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gravity Dams
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 ...

Dams Completed In 1954
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Interbasin Transfer
Interbasin transfer or transbasin diversion are (often hyphenated) terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized better for human development. The purpose of such water resource engineering schemes can be to alleviate water shortages in the receiving basin, to generate electricity, or both. Rarely, as in the case of the Glory River which diverted water from the Tigris to Euphrates River in modern Iraq, interbasin transfers have been undertaken for political purposes. While ancient water supply examples exist, the first modern developments were undertaken in the 19th century in Australia, India and the United States, feeding large cities such as Denver and Los Angeles. Since the 20th century many more similar projects have followed in other countries, including Israel and China, and contributions to the Green Revolution in India and hydropower developm ...

Kouhrang 2 Dam
The Kouhrang 2 Hydroelectric Power Station is located just south of Chelgard and about northwest of Shahrekord in Chaharmahal and Bakhtiari Province, Iran. The power station has an installed capacity of 33.3 MW and uses water diverted to the east from the Kouhrang River, via a small dam and the long Kouhrang 2 Tunnel, to produce power. Water from the Kouhrang is stored in a circular dam (Kouhrang 2 Dam) before being sent to the power station. The power station's three generators were commissioned between 2002 and 2004, the power plant were inaugurated in February 2005. Water discharged from the power station enters the Zayandeh River as part of a larger project to provide water to major cities like Isfahan. The intake for the power plant is located on the Kouhrang River () just downstream of the Kouhrang 1 Dam which also diverts water, via the long Kouhrang 2 Tunnel, to near Chelgard and was completed in 1953. The Kouhrang 3 Dam is planned downstream to regulate river flows and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kouhrang River
Koohrang (also known as Kouhrang and Kurang) is the name of a river, originating in the Zagros mountains of western Iran, which joins the Beheštābād river () to form the Karun, Iran's largest (by volume) river. A series of tunnels (Kuhrang Tunnels) have been built since the 1950s to redirect some of the Kuhrang's water toward the Zayandeh River to meet the demands of increased population in Esfahan and Yazd provinces. The Zayandeh River basin encompasses about and is connected to the upper Karun River basin (which drains to the Persian Gulf) by the Kuhrang Dam and Tunnel 1 () constructed in 1953 although first proposed in the early sixteenth century. Two additional tunnels ( Kurang 2 and Kurang 3) were constructed in late 1990s and early 2000s. A hydroelectric dam at Godar-e Langar (also known as Karun-4) would also supply piped water to Esfahan away if it is completed (Whitley and Gallagher, 1995). Dams have deleterious effects on a riverine fish and other fauna and are oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shah Abbas I
Abbas I ( fa, ; 27 January 157119 January 1629), commonly known as Abbas the Great (), was the 5th Safavid Shah (king) of Iran, and is generally considered one of the greatest rulers of Iranian history and the Safavid dynasty. He was the third son of Shah Mohammad Khodabanda. Although Abbas would preside over the apex of Safavid Iran's military, political and economic power, he came to the throne during a troubled time for the country. Under the ineffective rule of his father, the country was riven with discord between the different factions of the Qizilbash army, who killed Abbas' mother and elder brother. Meanwhile, Iran's enemies, the Ottoman Empire (its archrival) and the Uzbeks, exploited this political chaos to seize territory for themselves. In 1588, one of the Qizilbash leaders, Murshid Qoli Khan, overthrew Shah Mohammed in a coup and placed the 16-year-old Abbas on the throne. However, Abbas soon seized power for himself. Under his leadership, Iran developed the ghilma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
