Mosul Dam
Mosul Dam ( ar, سد الموصل), formerly known as Saddam Dam (), is the largest dam in Iraq. It is located on the Tigris river in the western governorate of Nineveh, upstream of the city of Mosul. The dam serves to generate hydroelectricity and provide water for downstream irrigation. At full capacity, the structure holds about of water and provides electricity to the 1.7 million residents of Mosul. The dam's main power station contains four Francis turbine–generators. A pumped-storage hydroelectricity power plant with a capacity of and a run-of-the-river dam downstream with a capacity also belong to the Mosul Dam scheme. It is the fourth largest dam in the Middle East, as measured by reserve capacity, capturing snowmelt from Turkey, some north. Built in the 1980s on a karst foundation, concerns over the dam's instability have led to major remediation and rehabilitation efforts since the 2003 invasion of Iraq.

Tigris
The Tigris () is the easternmost of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, and empties into the Persian Gulf. Geography The Tigris is 1,750 km (1,090 mi) long, rising in the Taurus Mountains of eastern Turkey about 25 km (16 mi) southeast of the city of Elazığ and about 30 km (20 mi) from the headwaters of the Euphrates. The river then flows for 400 km (250 mi) through Southeastern Turkey before becoming part of the Syria-Turkey border. This stretch of 44 km (27 mi) is the only part of the river that is located in Syria. Some of its affluences are Garzan, Anbarçayi, Batman, and the Great and the Little Zab. Close to its confluence with the Euphrates, the Tigris splits into several channels. First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriyah. ...

Fuse-plug
A fuse plug is a collapsible dam installed on spillways in dams to increase the dam's capacity. The principle behind the fuse plug is that the majority of water that overflows a dam's spillway can be safely dammed except in high flood conditions. The fuse plug may be a sand-filled container, a steel structure or a concrete block. Under normal flow conditions the water will spill over the fuse plug and down the spillway. In high flood conditions, where the water velocity may be so high that the dam itself may be put in danger, the fuse plug simply washes away, and the flood waters safely spill over the dam.

Grout Curtain
A grout curtain is a barrier that protects the foundation of a dam from seepage and can be made during initial construction or during repair. Additionally, they can be used to strengthen foundations and contain spills. Characteristics A grout curtain usually consists of a row of vertically drilled holes filled with pressurized grout, a process commonly known as pressure grouting. The holes are drilled in intervals and in such a way that they cross each other, creating a curtain. Method Grout is injected with grouting jets, which use a high-pressure fluid stream (i.e., slurry or water) to erode a cavity in the soil. See also *Levee *Dam failure A dam failure or dam burst is a catastrophic type of structural failure characterized by the sudden, rapid, and uncontrolled release of impounded water or the likelihood of such an uncontrolled release.

Gypsum
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula . It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt, Mesopotamia, Ancient Rome, the Byzantine Empire, and the Nottingham alabasters of Medieval England. Gypsum also crystallizes as translucent crystals of selenite. It forms as an evaporite mineral and as a hydration product of anhydrite. The Mohs scale of mineral hardness defines gypsum as hardness value 2 based on scratch hardness comparison. Etymology and history The word ''gypsum'' is derived from the Greek word (), "plaster". Because the quarries of the Montmartre district of Paris have long furnished burnt gypsum (calcined gypsum) used for various purposes, this dehydrated gypsum became known ...

Saddam Hussein
Saddam Hussein ( ; ar, صدام حسين, Ṣaddām Ḥusayn; 28 April 1937 – 30 December 2006) was an Iraqi politician who served as the fifth president of Iraq from 16 July 1979 until 9 April 2003.

As vice president under the ailing General Ahmed Hassan al-Bakr, and at a time when many groups were considered capable of overthrowing the government, Saddam created security forces through which he tightly controlled conflicts between the government and the armed forces. In the early 1970s, Saddam nationalised the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sir Alexander Gibb & Partners
Sir Alexander Gibb & Partners was a British firm of consulting civil engineers, based at Queen Anne's Lodge, Queen Anne's Gate and subsequently Telford House, Tothill Street, Westminster, London, until 1974, when it relocated to Earley House, 427 London Road, Reading, Berkshire. The firm had been founded in 1922 by noted Scottish civil engineer, Brigadier-General Sir Alexander Gibb. For the first ten years the business was not very rewarding financially although it was engaged on several important projects. Gibb and his colleague, noted electrical engineer Charles Hesterman Merz, designed Barking Power Station and later the Galloway Hydro Electric development, the first major work of its kind to be linked to the National Grid. Gibb resolved to make his firm the largest of its kind in the country and in time, the firm grew to the point where it was responsible for projects in several parts of the world. By the late 1980s/early 1990s, the firm was organised as a number of speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baghdad
Baghdad (; ar, بَغْدَاد , ) is the capital of Iraq and the second-largest city in the Arab world after Cairo. It is located on the Tigris near the ruins of the ancient city of Babylon and the Sassanid Persian capital of Ctesiphon. In 762 CE, Baghdad was chosen as the capital of the Abbasid Caliphate, and became its most notable major development project. Within a short time, the city evolved into a significant cultural, commercial, and intellectual center of the Muslim world. This, in addition to housing several key academic institutions, including the House of Wisdom, as well as a multiethnic and multi-religious environment, garnered it a worldwide reputation as the "Center of Learning". Baghdad was the largest city in the world for much of the Abbasid era during the Islamic Golden Age, peaking at a population of more than a million. The city was largely destroyed at the hands of the Mongol Empire in 1258, resulting in a decline that would linger through many c ...

Cuneiform
Cuneiform is a logo-syllabic script that was used to write several languages of the Ancient Middle East. The script was in active use from the early Bronze Age until the beginning of the Common Era. It is named for the characteristic wedge-shaped impressions (Latin: ) which form its signs. Cuneiform was originally developed to write the Sumerian language of southern Mesopotamia (modern Iraq). Cuneiform is the earliest known writing system. Over the course of its history, cuneiform was adapted to write a number of languages in addition to Sumerian. Akkadian texts are attested from the 24th century BC onward and make up the bulk of the cuneiform record. Akkadian cuneiform was itself adapted to write the Hittite language in the early second millennium BC. The other languages with significant cuneiform corpora are Eblaite, Elamite, Hurrian, Luwian, and Urartian. The Old Persian and Ugaritic alphabets feature cuneiform-style signs; however, they are unrelated to the cuneiform lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitanni
Mitanni (; Hittite cuneiform ; ''Mittani'' '), c. 1550–1260 BC, earlier called Ḫabigalbat in old Babylonian texts, c. 1600 BC; Hanigalbat or Hani-Rabbat (''Hanikalbat'', ''Khanigalbat'', cuneiform ') in Assyrian records, or ''Naharin'' in Egyptian texts, was a Hurrian-speaking state in northern Syria and southeast Anatolia (modern-day Turkey). Since no histories or royal annals/chronicles have yet been found in its excavated sites, knowledge about Mitanni is sparse compared to the other powers in the area, and dependent on what its neighbours commented in their texts. The Hurrians were in the region as of the late 3rd millennium BC. A king of Urkesh with a Hurrian name, Tupkish, was found on a clay sealing dated c. 2300 BC at Tell Mozan.Salvini, Mirjo.
