Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great f ...

Dams In The Tigris–Euphrates River System
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.

Buildings And Structures In Khuzestan Province
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 * Az ...

Hydroelectric Power Stations In Iran
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Bank
The World Bank is an international financial institution that provides loans and grants to the governments of low- and middle-income countries for the purpose of pursuing capital projects. The World Bank is the collective name for the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA), two of five international organizations owned by the World Bank Group. It was established along with the International Monetary Fund at the 1944 Bretton Woods Conference. After a slow start, its first loan was to France in 1947. In the 1970s, it focused on loans to developing world countries, shifting away from that mission in the 1980s. For the last 30 years, it has included NGOs and environmental groups in its loan portfolio. Its loan strategy is influenced by the Sustainable Development Goals as well as environmental and social safeguards. , the World Bank is run by a president and 25 executive directors, as well as 29 various v ...

Khuzestan
Khuzestan Province (also spelled Xuzestan; fa, استان خوزستان ''Ostān-e Xūzestān'') is one of the 31 provinces of Iran. It is in the southwest of the country, bordering Iraq and the Persian Gulf. Its capital is Ahvaz and it covers an area of . Since 2014, it has been part of Iran's Region 4. Historically, one of the most important regions of the Ancient Near East, Khuzestan is what historians refer to as ancient Elam, whose capital was in Susa. The Achaemenid Old Persian term for Elam was ''Hujiyā'' when they conquered it from the Elamites, which is present in the modern name. Khuzestan, meaning "the Land of the Khuz", refers to the original inhabitants of this province, the "Susian" people (Old Persian "Huza" or ''Huja'', as in the inscription at the tomb of Darius the Great at Naqsh-e Rostam). They are the Shushan of the Hebrew sources where they are recorded as "Hauja" or "Huja". In Middle Persian, the term evolves into "Khuz" and "Kuzi". The pre-Islamic Par ...
