Tabqa Dam
The Tabqa Dam (, ; ), or al-Thawra Dam as it is also named (, ; , literally "Revolution Dam"), most commonly known as Euphrates Dam (; ; ), is an earthen dam on the Euphrates, located upstream from the city of Raqqa in Raqqa Governorate, Syria. The city of Al-Thawrah is located immediately south of the dam. The dam is high and long and is the largest dam in Syria. Its construction led to the creation of Lake Assad, Syria's largest water reservoir. The dam was constructed between 1968 and 1973 with help from the Soviet Union. At the same time, an international effort was made to excavate and document as many archaeological remains as possible in the area of the future lake before they would be flooded by the rising water. When the flow of the Euphrates was reduced in 1974 to fill the lake behind the dam, a dispute broke out between Syria and Iraq (which is downstream) that was settled by intervention from Saudi Arabia and the Soviet Union. The dam was originally built to gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irrigation
Irrigation (also referred to as watering of plants) is the practice of applying controlled amounts of water to land to help grow crops, landscape plants, and lawns. Irrigation has been a key aspect of agriculture for over 5,000 years and has been developed by many cultures around the world. Irrigation helps to grow crops, maintain landscapes, and revegetation, revegetate disturbed soils in dry areas and during times of below-average rainfall. In addition to these uses, irrigation is also employed to protect crops from frost, suppress weed growth in grain fields, and prevent soil consolidation. It is also used to cool livestock, reduce dust, dispose of sewage, and support mining operations. Drainage, which involves the removal of surface and sub-surface water from a given location, is often studied in conjunction with irrigation. There are several methods of irrigation that differ in how water is supplied to plants. Surface irrigation, also known as gravity irrigation, is the olde ...

Excavations at Tell as-Sawda and Tell al-Ansari, just south of the old city of Aleppo, show that the area was occupied by Amorites by the latter part of the third millennium BC. That is also the time at which Aleppo is first mentioned in cuneiform tablets unearthed in Ebl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemins De Fer Syriens
Syrian Railways Corporation (, , CFS) is the national railway operator for the state of Syria, subordinate to the Ministry of Transport. It was established in 1956 and was headquartered in Aleppo. Syria's rail infrastructure has been severely compromised as a result of the ongoing conflict in the country. History The first railway in Syria opened when the country was part of the Ottoman Empire, with the gauge line from Damascus to the port city of Beirut in present-day Lebanon opened in 1895. The Hejaz railway opened in 1908 between Damascus and Medina in present-day Saudi Arabia also used gauge. Railways after this point were built to , including the Baghdad Railway. The French wanted an extension of the standard gauge railway to connect with Palestine Railways and so agreed the building of a branch line to Tripoli, Lebanon, operated by , also known as ''DHP''. The Baghdad Railway had progressed as far as Aleppo by 1912, with the branch to Tripoli complete, by the start ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Khabur (Euphrates)
The Khabur River is the largest perennial tributary to the Euphrates in Syria. Although the Khabur originates in Turkey, the karstic springs around Ras al-Ayn are the river's main source of water. Several important wadis join the Khabur north of Al-Hasakah, together creating what is known as the Khabur Triangle, or Upper Khabur area. From north to south, annual rainfall in the Khabur basin decreases from over 400 mm to less than 200 mm. This has made the river a vital water source for agriculture throughout history. The Khabur joins the Euphrates near the town of Busayrah. Name In ancient times, the river was known in Akkadian and Amorite as ''ḫabur'', Tell Fekherya bilingual inscription, see: in , and in . Tell Fekherya bilingual inscription, see: The river was well noted by ancient writers, with various names used by various writers: Ptolemy and Pliny the Elder called it the ''Chaboras'' (),Ptolemy, '' The Geography, 5.18.3; Pliny the Elder, Natural History, 3 ...

River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Ã…ke Sundborg
Ã…ke Sundborg (15 October 1921 – 23 May 2007) was a Swedish geographer and geomorphologist known for his contributions to the hydrology and geomorphological dynamics of rivers. He was active at Uppsala University where he studied under the supervision of Filip Hjulström eventually succeeding him on the chair of physical geography. Besides his studies of rivers Sundborg made contributions on the Urban climate, climate of cities, the distribution of loess and the sedimentation of reservoirs and lakes. He studied rivers in Sweden as well as various large rivers in Africa and Asia. Academic career Sundborg's licentiate (degree)#Finland and Sweden, ''filosofie licentiat'' thesis had as subject the city climate of Uppsala. The thesis came to be internationally recognized with climatologist Helmut Landsberg praising it for containing one of the first theories on the climate of cities.

Geomorphology
Geomorphology () is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes comprise the action of water, wind, ice, wildfire, and lif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
