Guanting Reservoir
Guanting Reservoir (), also known as Guanting Shuiku, is the first large-scale reservoir after the founding of the People's Republic of China. Guanting Reservoir is located at the junction of Beijing and Hebei Province, mostly in Huailai County, Hebei Province, and a small part in Yanqing County, Beijing. The reservoir is named after the dam built near the Guanting Town (官厅镇). History Guanting Reservoir started construction in October 1951 and was completed on 13 May 1954, with the main flow of water being the Yongding River in Huailai. The reservoir covers an area of 230 square kilometers and has a total storage capacity of 2.2 billion cubic meters. Guanting Reservoir was a major source of fresh water for Beijing and neighboring regions. Due to water contamination, the reservoir was withdrawn from the system to supply Beijing with drinking water Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or ...

Yongding River
The Yongding River () is a river in northern China. It is one of the main tributaries in the Hai River system and is the largest river to flow through Beijing. In recent years, the Beijing segment of the river has dried up due to environmental issues. The Beijing municipal government has invested 16 billion yuan in an effort to replace the riverbed with parkland or smaller bodies of water. Etymology The river was originally called Wuding River (), literally "unfixed river", because its flow was irregular. When the Kangxi Emperor reigned, he enacted various hydraulic engineering projects in the region to rein in the seasonal flooding. After those projects, the river was renamed to its modern name, which means "ever-fixed river". Geography The Yongding River is in length and drains an area of . It emerges from the Guancen Mountains (管涔山) in Ningwu County, Shanxi Province, where it is known as the Sanggan River (桑干河) and flows northeast into Inner Mongolia and th ...

Buildings And Structures In Beijing
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reservoirs In China
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] |

Drinking Water
Drinking water or potable water is water that is safe for ingestion, either when drunk directly in liquid form or consumed indirectly through food preparation. It is often (but not always) supplied through taps, in which case it is also called tap water. The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions. This 2004 article focuses on the USA context and uses data collected from the US military. For those who work in a hot climate, up to a day may be required. About 1 to 2 billion people lack safe drinking water. Water can carry vectors of disease and is a major cause of death and illness worldwide. Developing countries are most affected by unsafe drinking water. Sources Potable water is available in almost all populated areas of the world, although it may be expensive, and the supply may not always be sustainable. Sources where drinking water is commo ...

Water Contamination
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the water resource. Sources of water pollution are either point sources or non-point sources. Point sources have one identifiable cause, such as a storm drain, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fresh Water
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include non-salty mineral water, mineral-rich waters, such as chalybeate springs. Fresh water may encompass frozen water, frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ice pellets, sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranea (geography), subterranean subterranean river, rivers and underground lake, lakes. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of vascular plants and most insects, amphibians, reptiles, mammals and birds need fresh water to sur ...

Square Kilometer
The square kilometre (square kilometer in American spelling; symbol: km2) is a multiple of the square metre, the SI unit of area or surface area. In the SI unit of area (m2), 1 km2 is equal to 1M(m2). 1 km2 is equal to: * 1,000,000 square metres (m2) * 100 hectares (ha) It is also approximately equal to: * 0.3861 square miles * 247.1 acres Conversely: *1 m2 = 0.000001 (10−6) km2 *1 hectare = 0.01 (10−2) km2 *1 square mile = *1 acre = about The symbol "km2" means (km)2, square kilometre or kilometre squared and not k(m2), kilo–square metre. For example, 3 km2 is equal to = 3,000,000 m2, not 3,000 m2. Examples of areas of 1 square kilometre Topographical map grids Topographical map grids are worked out in metres, with the grid lines being 1,000 metres apart. * 1:100,000 maps are divided into squares representing 1 km2, each square on the map being one square centimetre in area and representing 1 km2 on the surface of the Earth. ...
