Two types of single-arch dams are in use, namely the constant-angle and the constant-radius dam. The constant-radius type employs the same face radius at all elevations of the dam, which means that as the channel grows narrower towards
3726-480: 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 word dam can be traced back to Middle English , and before that, from Middle Dutch , as seen in

The normal component of the weight of the arch ring may be taken by the arch action, while the normal hydrostatic pressure will be distributed as described above. For this type of dam, firm reliable supports at the abutments (either buttress or canyon side wall) are more important. The most desirable place for an arch dam is a narrow canyon with steep side walls composed of sound rock. The safety of an arch dam

10350-402: The buttress loads are heavy. In a gravity dam, the force that holds the dam in place against the push from the water is Earth's gravity pulling down on the mass of the dam. The water presses laterally (downstream) on the dam, tending to overturn the dam by rotating about its toe (a point at the bottom downstream side of the dam). The dam's weight counteracts that force, tending to rotate the dam
10488-501: The capital Amman . This gravity dam featured an originally 9-metre-high (30 ft) and 1 m-wide (3.3 ft) stone wall, supported by a 50 m-wide (160 ft) earthen rampart. The structure is dated to 3000 BC. However, the oldest continuously operational dam is Lake Homs Dam , built in Syria between 1319-1304 BC. The Ancient Egyptian Sadd-el-Kafara Dam at Wadi Al-Garawi, about 25 km (16 mi) south of Cairo ,
10626-595: The city. The masonry arch dam wall was designed by Lieutenant Percy Simpson who was influenced by the advances in dam engineering techniques made by the Royal Engineers in India . The dam cost £17,000 and was completed in 1856 as the first engineered dam built in Australia, and the second arch dam in the world built to mathematical specifications. The first such dam was opened two years earlier in France . It
10764-425: The constitutional court which was set up in 2012 in order to hear cases regarding the constitutionality of laws. Although Islam is the state religion , the constitution preserves religious and personal freedoms. Religious law only extends to matters of personal status such as divorce and inheritance in religious courts, and is partially based on Islamic sharia law. The special court deals with cases forwarded by
10902-671: The construction of the Rideau Canal in Canada near modern-day Ottawa and built a series of curved masonry dams as part of the waterway system. In particular, the Jones Falls Dam , built by John Redpath , was completed in 1832 as the largest dam in North America and an engineering marvel. In order to keep the water in control during construction, two sluices , artificial channels for conducting water, were kept open in
11040-618: The country's western border. Jordan has a small coastline along the Red Sea in its southwest, separated by the Gulf of Aqaba from Egypt . Amman is the country's capital and largest city , as well as the most populous city in the Levant . Modern-day Jordan has been inhabited by humans since the Paleolithic period. Three kingdoms developed in Transjordan during the Iron Age : Ammon , Moab and Edom , which were conquered by
11178-469: The dam by the water reduces the lateral (horizontal) force acting on the dam. Thus, the gravitational force required by the dam is lessened, i.e., the dam does not need to be so massive. This enables thinner dams and saves resources. A barrage dam is a special kind of dam that consists of a line of large gates that can be opened or closed to control the amount of water passing the dam. The gates are set between flanking piers which are responsible for supporting
11316-533: The dam was submitted by a consortium called Six Companies, Inc. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and the lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned over the dam to the federal government on 1 March 1936, more than two years ahead of schedule. By 1997, there were an estimated 800,000 dams worldwide, some 40,000 of them over 15 m (49 ft) high. In 2014, scholars from
11454-605: The dam. If large enough uplift pressures are generated there is a risk of destabilizing the concrete gravity dam. On a suitable site, a gravity dam can prove to be a better alternative to other types of dams. When built on a solid foundation, the gravity dam probably represents the best-developed example of dam building. Since the fear of flood is a strong motivator in many regions, gravity dams are built in some instances where an arch dam would have been more economical. Gravity dams are classified as "solid" or "hollow" and are generally made of either concrete or masonry. The solid form
11592-407: The dam. The first was near the base of the dam on its east side. A second sluice was put in on the west side of the dam, about 20 ft (6.1 m) above the base. To make the switch from the lower to upper sluice, the outlet of Sand Lake was blocked off. Hunts Creek near the city of Parramatta , Australia , was dammed in the 1850s, to cater to the demand for water from the growing population of
11730-631: The dam. The leakage has increased than before according to media report. However the Maharashtra government authorities state that the dam is safe and they will soon solve the leakage problem. Girish Mahajan, Maharashtra state water resource minister stated said that inquiry about this issue will also carried out as this dam was opened in 2001 and leakages started in just 15 years. However care needs to be taken to prevent Panshet dam tragedy in 1961. The Hydro Power Plant of 1 X 4 MW installed capacity has been set up at Dam Toe in year 2017 and commissioned in
11868-450: The dams' potential range and magnitude of environmental disturbances. The International Commission on Large Dams (ICOLD) defines a "large dam" as "A dam with a height of 15 m (49 ft) or greater from lowest foundation to crest or a dam between 5 m (16 ft) metres and 15 metres impounding more than 3 million cubic metres (2,400 acre⋅ft )". "Major dams" are over 150 m (490 ft) in height. The Report of
12006-653: The disintegration of the Assyrians' empire, Babylonians took control of the area. Although the kingdoms supported the Babylonians against Judah in the 597 BC sack of Jerusalem , they rebelled against Babylon a decade later. The kingdoms were reduced to vassals , a status they retained under the Persian and Hellenic empires. By the beginning of Roman rule around 63 BC, the kingdoms of Ammon, Edom and Moab had lost their distinct identities and were assimilated into
12144-734: The empire in 313 after co-emperors Constantine and Licinius signed an edict of toleration. In 380, the Edict of Thessalonica made Christianity the official state religion. Transjordan prospered during the Byzantine era, and Christian churches were built throughout the region. The Aqaba Church in Ayla was built during this era; it is considered to be the world's first purpose built Christian church . Umm ar-Rasas in southern Amman contains at least 16 Byzantine churches. Meanwhile, Petra's importance declined as sea trade routes emerged, and after
12282-626: The end much of Transjordan was disputed between the Ptolemies based in Egypt and the Seleucids based in Syria. The Nabataeans , nomadic Arabs based south of Edom, managed to establish an independent kingdom in 169 BC by exploiting the struggle between the two Greek powers. The Nabataean Kingdom controlled much of the trade routes of the region, and it stretched south along the Red Sea coast into
12420-514: The fedayeen and the resultant fighting led to the expulsion of Palestinian fighters from various PLO groups into Lebanon, in a conflict that became known as Black September . In 1973, Egypt and Syria waged the Yom Kippur War on Israel, and fighting occurred along the 1967 Jordan River cease-fire line. Jordan sent a brigade to Syria to attack Israeli units on Syrian territory but did not engage Israeli forces from Jordanian territory. At
12558-901: The first century AD. It is believed to be the mausoleum of the Arab Nabataean King Aretas IV . Roman legions under Pompey conquered much of the Levant in 63 BC, inaugurating a period of Roman rule that lasted four centuries. In 106 AD, Emperor Trajan annexed Nabataea unopposed and rebuilt the King's Highway which became known as the Via Traiana Nova road. The Romans gave the Greek cities of Transjordan—Philadelphia (Amman), Gerasa (Jerash), Gedara (Umm Quays), Pella (Tabaqat Fahl) and Arbila (Irbid)—and other Hellenistic cities in Palestine and southern Syria,
12696-561: The first large-scale arch dams. Three pioneering arch dams were built around the British Empire in the early 19th century. Henry Russel of the Royal Engineers oversaw the construction of the Mir Alam dam in 1804 to supply water to the city of Hyderabad (it is still in use today). It had a height of 12 m (39 ft) and consisted of 21 arches of variable span. In the 1820s and 30s, Lieutenant-Colonel John By supervised
12834-742: The first was the Roman-built dam bridge in Dezful , which could raise water 50 cubits (c. 23 m) to supply the town. Also diversion dams were known. Milling dams were introduced which the Muslim engineers called the Pul-i-Bulaiti . The first was built at Shustar on the River Karun , Iran, and many of these were later built in other parts of the Islamic world . Water was conducted from
12972-534: The force of water. A fixed-crest dam is a concrete barrier across a river. Fixed-crest dams are designed to maintain depth in the channel for navigation. They pose risks to boaters who may travel over them, as they are hard to spot from the water and create induced currents that are difficult to escape. There is variability, both worldwide and within individual countries, such as in the United States, in how dams of different sizes are categorized. Dam size influences construction, repair, and removal costs and affects
13110-637: The former crown prince of Jordan, who was placed under house arrest, after having been accused of working to "destabilize" the kingdom. Jordan sits strategically at the crossroads of the continents of Asia, Africa and Europe, in the Levant area of the Fertile Crescent , a cradle of civilization . Its area is 89,341 square kilometres (34,495 sq mi), and it is 400 kilometres (250 mi) long between its northernmost and southernmost points; Umm Qais and Aqaba respectively. The kingdom lies between 29° and 34° N , and 34° and 40° E . It
13248-731: The foundation for Aqaba 's free-trade zone and Jordan's flourishing information and communication technology sector. He also set up five other special economic zones. However, during the following years Jordan's economy experienced hardship as it dealt with the effects of the Great Recession and spillover from the Arab Spring . Al-Qaeda under Abu Musab al-Zarqawi 's leadership launched coordinated explosions in three hotel lobbies in Amman on 9 November 2005, resulting in 60 deaths and 115 injured. The bombings, which targeted civilians, caused widespread outrage among Jordanians. The attack
13386-698: The highlands east of the Dead Sea; and Edom in the area around Wadi Araba in the south. The northwestern region of the Transjordan, known then as Gilead , was settled by the Israelites . The three kingdoms continually clashed with the neighbouring Hebrew kingdoms of Israel and Judah , centered west of the Jordan River. One record of this is the Mesha Stele , erected by the Moabite king Mesha in 840 BC; in an inscription on it, he lauds himself for
13524-645: The main stream of the Kaveri River in Tamil Nadu , South India . The basic structure dates to the 2nd century AD and is considered one of the oldest water diversion or water regulating structures still in use. The purpose of the dam was to divert the waters of the Kaveri across the fertile delta region for irrigation via canals. Du Jiang Yan is the oldest surviving irrigation system in China that included
13662-680: The names of many old cities, such as Amsterdam and Rotterdam . Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan , dating to 3,000 BC. Egyptians also built dams, such as Sadd-el-Kafara Dam for flood control. In modern-day India, Dholavira had an intricate water-management system with 16 reservoirs and dams. The Great Dam of Marib in Yemen, built between 1750 and 1700 BC,
13800-591: The northwest are clothed in natural forests of pine , deciduous oak , evergreen oak , pistachio and wild olive . Mammal and reptile species include, the long-eared hedgehog , Nubian ibex , wild boar , fallow deer , Arabian wolf , desert monitor , honey badger , glass snake , caracal , golden jackal and the roe deer , among others.

13938-507: The northwest, the capital Amman and As-Salt in the central west, and Madaba , Al-Karak and Aqaba in the southwest. Major towns in the east are the oasis towns of Azraq and Ruwaished . In the west, a highland area of arable land and Mediterranean evergreen forestry drops suddenly into the Jordan Rift Valley . The rift valley contains the Jordan River and the Dead Sea , which separates Jordan from Israel. Jordan has
14076-531: The oldest large-scale representations of humans ever found. During the Chalcolithic period (4500–3600 BC), several villages emerged in Transjordan including Tulaylet Ghassul in the Jordan Valley ; a series of circular stone enclosures in the eastern basalt desert from the same period have long baffled archaeologists. Fortified towns and urban centres first emerged in the southern Levant early in
14214-683: The other basic dam designs which had been unknown until then. These include arch-gravity dams , arch dams , buttress dams and multiple arch buttress dams , all of which were known and employed by the 2nd century AD (see List of Roman dams ). Roman workforces also were the first to build dam bridges, such as the Bridge of Valerian in Iran. In Iran , bridge dams such as the Band-e Kaisar were used to provide hydropower through water wheels , which often powered water-raising mechanisms. One of
14352-429: The other way about its toe. The designer ensures that the dam is heavy enough that the dam's weight wins that contest. In engineering terms, that is true whenever the resultant of the forces of gravity acting on the dam and water pressure on the dam acts in a line that passes upstream of the toe of the dam. The designer tries to shape the dam so if one were to consider the part of the dam above any particular height to be
14490-607: The outbreak of the 1916 Arab Revolt during World War I , which ended four centuries of stagnation under Ottoman rule. The revolt was led by Sharif Hussein of Mecca, scion of the Hashemite family of the Hejaz, and his sons Abdullah , Faisal and Ali . Locally, the revolt garnered the support of the Transjordanian tribes, including Bedouins, Circassians and Christians . The Allies of World War I , including Britain and France whose imperial interests converged with
14628-408: The peace treaty. On 7 February 1999, Abdullah II ascended the throne upon the death of his father Hussein, who had ruled for nearly 50 years. Abdullah embarked on economic liberalization when he assumed the throne, and his reforms led to an economic boom which continued until 2008. Abdullah II has been credited with increasing foreign investment, improving public-private partnerships and providing
14766-607: The principles behind dam design. In France, J. Augustin Tortene de Sazilly explained the mechanics of vertically faced masonry gravity dams, and Zola's dam was the first to be built on the basis of these principles. The era of large dams was initiated with the construction of the Aswan Low Dam in Egypt in 1902, a gravity masonry buttress dam on the Nile River . Following their 1882 invasion and occupation of Egypt ,
14904-561: The provisions of the mandate dealing with Jewish settlement. On 11 April 1921 the Emirate of Transjordan was established with Abdullah as emir. In September 1922, the Council of the League of Nations recognized Transjordan as a state under the terms of the Transjordan memorandum . Transjordan remained a British mandate until 1946, but it had been granted a greater level of autonomy than
15042-537: The region west of the Jordan River. Multiple difficulties emerged upon the assumption of power in the region by the Hashemite leadership. In Transjordan, small local rebellions at Kura in 1921 and 1923 were suppressed by Abdullah's forces with the help of the British. Wahhabis from Najd regained strength and repeatedly raided the southern parts of his territory, seriously threatening the emir's position. The emir
15180-818: The route that connected Syria to the Hejaz. Several of the Ayyubid castles were used and expanded by the Mamluks (1260–1516), who divided Transjordan between the provinces of Karak and Damascus. During the next century Transjordan experienced Mongol attacks, but the Mongols were ultimately repelled by the Mamluks at the Battle of Ain Jalut (1260). In 1516 the Ottoman Caliphate 's forces conquered Mamluk territory . Agricultural villages in Transjordan witnessed
15318-546: The secret 1916 Sykes–Picot Agreement , which divided the region into French and British spheres of influence, and the 1917 Balfour Declaration , in which Britain announced its support for the establishment of a "national home" for Jews in Palestine. This was seen by the Hashemites and the Arabs as a betrayal of their previous agreements with the British, including the 1915 McMahon–Hussein Correspondence , in which
15456-487: The state of New Mexico defines a jurisdictional dam as 25 feet or greater in height and storing more than 15 acre-feet or a dam that stores 50 acre-feet or greater and is six feet or more in height (section 72-5-32 NMSA), suggesting that dams that do not meet these requirements are non-jurisdictional. Most US dams, 2.41 million of a total of 2.5 million dams, are not under the jurisdiction of any public agency (i.e., they are non-jurisdictional), nor are they listed on
15594-524: The term is used to denote the lands east of the river. The Hebrew Bible uses the term עבר הירדן Ever ha'Yarden ( lit. ' the other side of the Jordan ' ) for the area. Early Arab chronicles call the river Al-Urdunn (a term cognate to the Hebrew Yarden ). Jund Al-Urdunn was a military district around the river in the early Islamic era. Later, during the Crusades in
15732-608: The throne in 1953 at age 17. Jordan witnessed great political uncertainty in the following period. The 1950s was a period of political upheaval, as Nasserism and Pan-Arabism swept the Arab World. On 1 March 1956, King Hussein Arabized the command of the Army by dismissing a number of senior British officers, an act made to remove remaining foreign influence in the country. In 1958, Jordan and neighbouring Hashemite Iraq formed
15870-489: The trust of Transjordan's tribal leaders before scrambling to convince them of the benefits of an organized government. Abdullah's successes drew the envy of the British, even when it was in their interest. The British reluctantly accepted Abdullah as ruler of Transjordan after having given him a six-month trial. In March 1921, the British decided to add Transjordan to their Mandate for Palestine , in which they would implement their " Sharifian Solution " policy without applying
16008-467: The upper Senate are directly appointed by the king, the constitution mandates that they be veteran politicians, judges and generals who previously served in the government or in the House of Representatives. The 130 members of the lower House of Representatives are elected through party-list proportional representation in 23 constituencies for a 4-year term. Minimum quotas exist in the House of Representatives for women (15 seats, though they won 20 seats in
16146-549: The vegetation becomes more scrubby and transitions to steppe-type vegetation. Forests cover 1.5 million dunums (1,500 km ), less than 2% of Jordan, making Jordan among the world's least forested countries, the international average being 15%. Plant species and genera include the Aleppo pine , Sarcopoterium , Salvia dominica , black iris , Tamarix , Anabasis , Artemisia , Acacia , Mediterranean cypress and Phoenecian juniper . The mountainous regions in
16284-736: The war. The Arab states were defeated, and Jordan lost control of the West Bank to Israel. The War of Attrition with Israel followed, which included the 1968 Battle of Karameh where the combined forces of the Jordanian Armed Forces and the Palestine Liberation Organization (PLO) repelled an Israeli attack on the Karameh camp on the Jordanian border with the West Bank. Despite the fact that
16422-406: The water level and to prevent the sea from entering the marshlands. Such dams often marked the beginning of a town or city because it was easy to cross the river at such a place, and often influenced Dutch place names. The present Dutch capital, Amsterdam (old name Amstelredam ), started with a dam on the river Amstel in the late 12th century, and Rotterdam began with a dam on the river Rotte ,
16560-642: The water load, and are often used to control and stabilize water flow for irrigation systems. An example of this type of dam is the now-decommissioned Red Bluff Diversion Dam on the Sacramento River near Red Bluff, California . Barrages that are built at the mouths of rivers or lagoons to prevent tidal incursions or use the tidal flow for tidal power are known as tidal barrages . Embankment dams are made of compacted earth, and are of two main types: rock-fill and earth-fill. Like concrete gravity dams, embankment dams rely on their weight to hold back
16698-581: The world is the 305 m-high (1,001 ft) Jinping-I Dam in China . As with large dams, small dams have multiple uses, such as, but not limited to, hydropower production, flood protection, and water storage. Small dams can be particularly useful on farms to capture runoff for later use, for example, during the dry season. Small scale dams have the potential to generate benefits without displacing people as well, and small, decentralised hydroelectric dams can aid rural development in developing countries. In
16836-514: The year 2019. One unit of Horizontal Francis Turbine with Synchronous Generator has been installed. The electricity produced is being evacuated to nearest MSETCL's Pirangut Substation. Dam#Earth-fill dams 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
16974-546: Was forcibly ended in 1841, with Ottoman rule restored. Only after Pasha's campaign did the Ottoman Empire try to solidify its presence in the Syria Vilayet , which Transjordan was part of. A series of tax and land reforms ( Tanzimat ) in 1864 brought some prosperity back to agriculture and to abandoned villages; the end of virtual autonomy led a backlash in other areas of Transjordan. Muslim Circassians and Chechens , fleeing Russian persecution , sought refuge in
17112-548: Was 102 m (335 ft) long at its base and 87 m (285 ft) wide. The structure was built around 2800 or 2600 BC as a diversion dam for flood control, but was destroyed by heavy rain during construction or shortly afterwards. During the Twelfth Dynasty in the 19th century BC, the Pharaohs Senosert III, Amenemhat III , and Amenemhat IV dug a canal 16 km (9.9 mi) long linking
17250-522: Was a temporary, practical measure and that Jordan was holding the territory as a "trustee" pending a future settlement. King Abdullah was assassinated at the Al-Aqsa Mosque in 1951 by a Palestinian militant, amid rumors he intended to sign a peace treaty with Israel. Abdullah was succeeded by his son Talal , who established the country's modern constitution in 1952. Illness caused Talal to abdicate to his eldest son Hussein , who ascended to
17388-602: Was an engineering wonder, and Eflatun Pinar, a Hittite dam and spring temple in Turkey, dates to the 15th and 13th centuries BC. The Kallanai Dam in South India, built in the 2nd century AD, is one of the oldest water regulating structures still in use. Roman engineers built dams with advanced techniques and materials, such as hydraulic mortar and Roman concrete, which allowed for larger structures. They introduced reservoir dams, arch-gravity dams, arch dams, buttress dams, and multiple arch buttress dams. In Iran, bridge dams were used for hydropower and water-raising mechanisms. During
17526-453: Was built. The system included 16 reservoirs, dams and various channels for collecting water and storing it. One of the engineering wonders of the ancient world was the Great Dam of Marib in Yemen . Initiated sometime between 1750 and 1700 BC, it was made of packed earth – triangular in cross-section, 580 m (1,900 ft) in length and originally 4 m (13 ft) high – running between two groups of rocks on either side, to which it
17664-434: Was linked by substantial stonework. Repairs were carried out during various periods, most importantly around 750 BC, and 250 years later the dam height was increased to 7 m (23 ft). After the end of the Kingdom of Saba , the dam fell under the control of the Ḥimyarites (c. 115 BC) who undertook further improvements, creating a structure 14 m (46 ft) high, with five spillways, two masonry-reinforced sluices,
17802-413: Was occupied by Israel in 1967 . Jordan renounced its claim to the territory to the Palestinians in 1988 and signed a peace treaty with Israel in 1994. Jordan is a semi-arid country, covering an area of 89,342 km (34,495 sq mi) with a population of 11.5 million, making it the eleventh-most populous Arab country . The dominant majority, or around 95% of the country's population,
17940-489: Was part of. During this period, the southernmost region of the country, including Ma'an and Aqaba , was also claimed by the neighbouring Kingdom of Hejaz . The nascent Hashemite Kingdom over the region of Syria was forced to surrender to French troops on 24 July 1920 during the Battle of Maysalun ; the French occupied only the northern part of Syria, leaving Transjordan in a period of interregnum . Arab aspirations failed to gain international recognition, due mainly to
18078-404: Was possibly the world's first concrete arch dam. Designed by Henry Charles Stanley in 1880 with an overflow spillway and a special water outlet, it was eventually heightened to 10 m (33 ft). In the latter half of the nineteenth century, significant advances in the scientific theory of masonry dam design were made. This transformed dam design from an art based on empirical methodology to
18216-416: Was raised to the status of a kingdom under the name of the Hashemite Kingdom of Jordan in Arabic, with Abdullah as its first king; although it continued to be referred to as the Hashemite Kingdom of Transjordan in English until 1949. 25 May is now celebrated as the nation's Independence Day , a public holiday . Jordan became a member of the United Nations on 14 December 1955. On 15 May 1948, as part of
18354-481: Was re-introduced to the Jordanian parliament in the 2016 general election , a move which he said would eventually lead to establishing parliamentary governments. Jordan was left largely unscathed from the violence that swept the region despite an influx of 1.4 million Syrian refugees into the natural resources-lacking country and the emergence of the Islamic State of Iraq and the Levant (ISIL). On 4 April 2021, 19 people were arrested , including Prince Hamzeh ,
18492-400: Was signed on 26 October 1994. In 1997, in retribution for a bombing , Israeli agents entered Jordan using Canadian passports and poisoned Khaled Mashal , a senior Hamas leader living in Jordan. Bowing to intense international pressure, Israel provided an antidote to the poison and released dozens of political prisoners, including Sheikh Ahmed Yassin , after King Hussein threatened to annul
18630-461: Was the first French arch dam of the industrial era , and it was built by François Zola in the municipality of Aix-en-Provence to improve the supply of water after the 1832 cholera outbreak devastated the area. After royal approval was granted in 1844, the dam was constructed over the following decade. Its construction was carried out on the basis of the mathematical results of scientific stress analysis. The 75-miles dam near Warwick , Australia,
18768-445: Was the largest masonry dam in the world. The Hoover Dam is a massive concrete arch-gravity dam , constructed in the Black Canyon of the Colorado River , on the border between the US states of Arizona and Nevada between 1931 and 1936 during the Great Depression . In 1928, Congress authorized the project to build a dam that would control floods, provide irrigation water and produce hydroelectric power . The winning bid to build
18906-415: Was to be kept separate from that of Palestine. The second meeting took place in Umm Qais on 2 September, where the British representative Major Fitzroy Somerset received a petition that demanded: an independent Arab government in Transjordan to be led by an Arab prince (emir); land sale in Transjordan to Jews be stopped as well as the prevention of Jewish immigration there; that Britain establish and fund
19044-426: Was unable to repel those raids without the aid of the local Bedouin tribes and the British, who maintained a military base with a small Royal Air Force detachment close to Amman. The Treaty of London , signed by the British government and the Emir of Transjordan on 22 March 1946, recognised the independence of the state. On 25 May 1946, the day that the treaty was ratified by the Transjordan parliament, Transjordan
