Dams In Denmark
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] |

Amenemhat III
:''See Amenemhat, for other individuals with this name.'' Amenemhat III ( Ancient Egyptian: ''Ỉmn-m-hꜣt'' meaning 'Amun is at the forefront'), also known as Amenemhet III, was a pharaoh of ancient Egypt and the sixth king of the Twelfth Dynasty of the Middle Kingdom. He was elevated to throne as co-regent by his father Senusret III, with whom he shared the throne as the active king for twenty years. During his reign, Egypt attained its cultural and economic zenith of the Middle Kingdom. The aggressive military and domestic policies of Senusret III, which re-subjugated Nubia and wrested power from the nomarchs, allowed Amenemhat III to inherit a stable and peaceful Egypt. He directed his efforts towards an extensive building program with particular focus on Faiyum. Here he dedicated a temple to Sobek, a chapel to Renenutet, erected two colossal statues of himself in Biahmu, and contributed to excavation of Lake Moeris. He built for himself two pyramids at Dahshur and Hawar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twelfth Dynasty Of Egypt
The Twelfth Dynasty of ancient Egypt (Dynasty XII) is considered to be the apex of the Middle Kingdom by Egyptologists. It often is combined with the Eleventh, Thirteenth, and Fourteenth dynasties under the group title, Middle Kingdom. Some scholars only consider the 11th and 12th dynasties to be part of the Middle Kingdom. History The chronology of the Twelfth Dynasty is the most stable of any period before the New Kingdom. The Turin Royal Canon gives 213 years (1991–1778 BC). Manetho stated that it was based in Thebes, but from contemporary records it is clear that the first king of this dynasty, Amenemhat I, moved its capital to a new city named "Amenemhat-itj-tawy" ("Amenemhat the Seizer of the Two Lands"), more simply called, Itjtawy. The location of Itjtawy has not been discovered yet, but is thought to be near the Fayyum, probably near the royal graveyards at el-Lisht. The order of its rulers of the Twelfth Dynasty is well known from several sources: two lists re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diversion Dam
A diversion dam is a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir; instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming an onground or groundwater reservoir or a storm drain. An early diversion dam is the Ancient Egyptian Sadd el-Kafara Dam at Wadi Al-Garawi, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and 87 metres wide. It was destroyed by a flood while it was still under construction.Günther Garbrecht: "Wasserspeicher (Talsperren) in der Antike", ''Antike Welt'', 2nd special edition: ''Antiker Wasserbau'' (1986), pp.51-64 (52f.)

Cairo
Cairo ( ; ar, القاهرة, al-Qāhirah, ) is the capital of Egypt and its largest city, home to 10 million people. It is also part of the largest urban agglomeration in Africa, the Arab world and the Middle East: The Greater Cairo metropolitan area, with a population of 21.9 million, is the 12th-largest in the world by population. Cairo is associated with ancient Egypt, as the Giza pyramid complex and the ancient cities of Memphis and Heliopolis are located in its geographical area. Located near the Nile Delta, the city first developed as Fustat, a settlement founded after the Muslim conquest of Egypt in 640 next to an existing ancient Roman fortress, Babylon. Under the Fatimid dynasty a new city, ''al-Qāhirah'', was founded nearby in 969. It later superseded Fustat as the main urban centre during the Ayyubid and Mamluk periods (12th–16th centuries). Cairo has long been a centre of the region's political and cultural life, and is titled "the city of a thousand m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
