Silveh Dam
The Silveh Dam is an earth-fill embankment dam on the Lavin River just downstream of the village of Silveh in Piranshahr County, West Azerbaijan Province, Iran. The primary purpose of the dam is interbasin transfer for irrigation. Since completion, a tunnel and canals shift water from the reservoir north to the Chaparabad area. The project essentially transfers water from the Little Zab River basin to the Lake Urmia basin in an effort to help replenish the lake and irrigate about of farmland. Construction on the dam began in 2004 and it was expected to be complete by the end of 2015. The dam was effectively completed as of 2018. The village of Silveh will be flooded when the reservoir is impounded. The dam is above its foundation with a length of . It has an uncontrolled spillway with a maximum discharge capacity of . The reservoir created by the dam will store of water. Near the northeastern edge of the reservoir water will be able to enter a long tunnel which will discharge ...

Lake Urmia
Lake Urmia; az, اۇرمۇ گؤلۆ, script=Arab, italic=no, Urmu gölü; ku, گۆلائوو رمیەیێ, Gola Ûrmiyeyê; hy, Ուրմիա լիճ, Urmia lich; arc, ܝܡܬܐ ܕܐܘܪܡܝܐ is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East and the sixth-largest saltwater lake on Earth, with a surface area of approximately , a length of , a width of , and a maximum depth of . By late 2017, the lake had shrunk to 10% of its former size (and 1/60 of water volume in 1998) due to persistent general drought in Iran, but also the damming of the local rivers that flow into it, and the pumping of groundwater from the surrounding area. This dry spell was broken in 2019 and the lake is now filling up once again, due to both increased rain and water diversion from the Zab River by th ...

Dams In West Azerbaijan Province
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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Dams And Reservoirs In Iran
Major dam construction started in Iran in the 1950s. Some fourteen large dams were built with the help of foreign engineers and advisors during two decades preceding the Islamic Revolution. In the post-revolution era, Iran's dam building capacity was significantly strengthened, with some 200 contracting companies, 70 consultant firms and 30 corporations as well as hundreds of hydroelectric manufacturing units having been established inside of Iran in less than three decades. In addition to the necessity of generating electricity, Iran needs dams to effectively control and manage a growing water shortage across the country. Iran was constructing 88 small and large dams in 2007. On average, close to two billion cubic meters of water are added to the country’s water reserves annually. As of 2010, Iran has constructed 588 dams (big and small), with 137 more under construction and 546 planned. Major reservoirs and dams in Iran *Alavian Dam * Alqadir Dam * Amir Kabir Dam * Aza ...

Sardasht Dam
The Sardasht Dam is an embankment dam currently under construction on the Little Zab southeast of Sardasht in the Iranian province of West Azerbaijan. Reconnaissance studies for the dam were completed in 1999 by Moshanir Consulting Engineers Company. When complete, it will be a tall and long rock-fill earth core dam. It will support a hydroelectric power station with an installed capacity of 150 MW and expected annual generation of 482 GWh. The construction contract for the dam was awarded in 2009. Official construction on the dam began in 2011. The river diversion tunnels were complete in November 2012 in a ceremony attended by Iran's Ministry of Energy Majid Namjoo. The dam began to impound its reservoir on 22 June 2017.

Piranshahr
Piranshahr ( fa, پیرانشهر; ckb, پیرانشار, Pîranşar) is a city located in West Azerbaijan Province in west Iran. It is the capital of Piranshahr County. Piranshahr is the center of the traditional region of Mukriyan. The government's mid-year census for 2016 puts Piranshahr's population at 91,515 compared with the 1996 figure of 34,000. Etymology According to the Arab geographer Yaqut al-Hamawi, the name of the city is derived from the famous figure of ''Shahnameh'' Piran Viseh Piran is a Turanian figure in ''Shahnameh'', the national epic of Greater Iran. Beside Shahnameh, Piran is also mentioned in other sources such as Tabari and Tha'ālibī. He is the king of Khotan and the spahbed of Afrasiab, the king of Turan. He is described as a wise and intelligent man, seeking to bring peace to Iran and Turan. In old Iranian writings, Piran and Aghrirat are the only Turanians that have been described positively.

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a stru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Zab
The Little Zab or Lower Zab (, ''al-Zāb al-Asfal''; or '; , ''Zâb-e Kuchak''; , ''Zāba Taḥtāya'') is a river that originates in Iran and joins the Tigris just south of Al Zab in the Kurdistan region of Iraq. It is approximately long and drains an area of about . The river is fed by rainfall and snowmelt, resulting in a peak discharge in spring and low water in summer and early fall. Two dams have been built on the Little Zab, regulating the river flow, providing water for irrigation and generating hydroelectricity. The Zagros Mountains have been occupied since at least the Lower Palaeolithic, but the earliest archaeological site in the Little Zab basin, Barda Balka, dates to the Middle Palaeolithic. Human occupation of the Little Zab basin has been attested for every period since then. Course The Little Zab rises in the Zagros Mountains in Iran at an elevation of circa amsl. In its upper reaches, the course of the Little Zab is determined by the alignment of the major ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 develo ...
