Reservoirs In Pakistan
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by creeks, rivers or rainwater that runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typically lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rainwater
Rain is a form of precipitation where water droplets that have condensed from atmospheric water vapor fall under gravity. Rain is a major component of the water cycle and is responsible for depositing most of the fresh water on the Earth. It provides water for hydroelectric power plants, crop irrigation, and suitable conditions for many types of ecosystems. The major cause of rain production is moisture moving along three-dimensional zones of temperature and moisture contrasts known as weather fronts. If enough moisture and upward motion is present, precipitation falls from convective clouds (those with strong upward vertical motion) such as cumulonimbus (thunder clouds) which can organize into narrow rainbands. In mountainous areas, heavy precipitation is possible where upslope flow is maximized within windward sides of the terrain at elevation which forces moist air to condense and fall out as rainfall along the sides of mountains. On the leeward side of mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Llyn Celyn
Llyn Celyn () is a reservoir constructed between 1960 and 1965 including the highly controversial Tryweryn flooding in the valley of the River Afon Tryweryn, Tryweryn in Gwynedd, Wales. This included the forcible removal of the Capel Celyn village residents despite protest and opposition of Welsh MPs. With an area of , it measures roughly long by wide, and has a maximum depth of . It has the capacity to hold of water. It was originally to be named ''Llyn Tryweryn Mawr'' (meaning "great Tryweryn lake"), but in September 1964 Liverpool Corporation agreed to the name change following a letter from the Tryweryn Defence Committee. Construction and opposition Construction of the reservoir for Liverpool Corporation Waterworks involved flooding the village of Capel Celyn and adjacent farmland, a deeply controversial move. Much of the opposition was brought about because the village was a stronghold of Culture of Wales, Welsh culture and the Welsh language, whilst the reservoir w ...

It has historically been considered the List of river systems by length, longest river in the world, though this has been contested by research suggesting that the Amazon River is slightly longer.Amazon Longer Than Nile River, Scientists Say Of the world's major rivers, the Nile has one of the lowest average annual flow rates.

Lake Nasser
Lake Nasser ( ', ) is a large reservoir (water), reservoir in southern Egypt and northern Sudan. It was created by the construction of the Aswan Dam, Aswan High Dam and is one of the List of reservoirs by volume, largest man-made lakes in the world. Before its creation, the project faced opposition from Sudan as it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled. In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake. The lake has become an important economic resource in Egypt, improving agriculture and touting robust fishing and tourism industries. Strictly speaking, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia ( ', ). __TOC__ Physical characteristics The lake is some long and across at its widest point, which is near the Tropic ...

Aswan Dam
The Aswan Dam, or Aswan High Dam, is one of the world's largest embankment dams, which was built across the Nile in Aswan, Egypt, between 1960 and 1970. When it was completed, it was the tallest earthen dam in the world, surpassing the Chatuge Dam in the United States. The dam, which created the Lake Nasser reservoir, was built upstream of the Aswan Low Dam, which had been completed in 1902 and was already at its maximum utilization. Construction of the High Dam became a key objective of the military regime that took power following the 1952 Egyptian revolution. With its ability to better control flooding, provide increased water storage for irrigation and generate hydroelectricity, the dam was seen as pivotal to Egypt's planned industrialization. Like the earlier implementation, the High Dam has had a significant effect on the Economy of Egypt, economy and culture of Egypt. Before the High Dam was built, even with the old dam in place, the annual flooding of the Nile during la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abu Simbel
Abu Simbel is a historic site comprising two massive Rock-cut architecture, rock-cut Egyptian temple, temples in the village of Abu Simbel (village), Abu Simbel (), Aswan Governorate, Upper Egypt, near the border with Sudan. It is located on the western bank of Lake Nasser, about southwest of Aswan (about by road). The twin temples were originally carved out of the mountainside in the 13th century BC, during the Nineteenth Dynasty of Egypt, 19th Dynasty reign of the Pharaoh Ramesses II. Their huge external rock relief figures of Ramesses II have become iconic. His wife, Nefertari, and children can be seen in smaller figures by his feet. Sculptures inside the Great Temple commemorate Ramesses II's heroic leadership at the Battle of Kadesh. The complex was Structure relocation, relocated in its entirety in 1968 to higher ground to avoid it being submerged by Lake Nasser, the Aswan Dam reservoir.

Pipeline
A pipeline is a system of Pipe (fluid conveyance), pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries around the world. The United States had 65%, Russia had 8%, and Canada had 3%, thus 76% of all pipeline were in these three countries. The main attribute to pollution from pipelines is caused by corrosion and leakage. ''Pipeline and Gas Journal''s worldwide survey figures indicate that of pipelines are planned and under construction. Of these, represent projects in the planning and design phase; reflect pipelines in various stages of construction. Liquids and gases are transported in pipelines, and any chemically stable substance can be sent through a pipeline. Pipelines exist for the transport of crude and refined petroleum, fuels—such as oil, natural gas and biofuels—and other fluids including sewage, slurry, water, beer, hot wa ...

Aqueduct (water Supply)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to aqueduct (bridge), a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, the ancient Near East, Roman aqueduct, ancient Rome, Chapultepec aqueduct, ancient Aztec, and Inca aqueducts, ancient Inca. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
