Climate, geography, demography, and water resources of China
From WaterWiki
The Water resources of China include 2,711.5 cubic kilometers of mean annual runoff in its rivers and 828.8 cubic kilometers which was pumped annually from shallow aquifers circa 2000. As pumping water draws water from nearby rivers, the total available resource is 2,821.4 cubic kilometers. 80.9% of these resources are in the Yangtze River Basin. In 1993 498,720 square kilometers were irrigated.

[edit] Climate
China spans, due to its large size and dramatic altitude range, several distinct climate zone. Generally the north and interior are a temperate continental climate, while the south, at least near the sea, is subtropical. In January, 2008 China was impacted by a country-wide snowstorm which brought much of the country to a standstill, particularly affecting train travel from Guangzhou in southern China.[1][2][3][4] This event followed heavy snows earlier in the month which affected Iran and Afghanistan.[5]
[edit] Three Gorges Project
The Three Gorges Project on the Yangtze River is a huge dam which is part of planned hydropower development.
[edit] Problems in water management
China is facing many problems in managing its water resources. Flooding is still a major problem, demand for water is rapidly exceeding supply and water pollution has yet to be effectively controlled. The contamination of the Songhe River following an explosion at a Jilin chemical plant in November 2005 highlighted the extent of the water pollution problem. Algal blooms have occurred on 3 of its largest lakes, Lake Tai, Lake Chaohu, and Lake Dianchi. In January, 2008 the State Council promulgated a plan to address water pollution in its lakes. The plan proposes regulation of wastewater, closing of factories near lakes which release large amounts of wastewater, improvement of sewage treatment facilities, elimination of fish farms near major lakes affected by eutrophication and regulation of the siting of fish farms. Mediation of pollution in the lake behind the Three Gorges Dam and the use of pesticides with highly toxic residue and detergents containing phosphorus near large lakes are also addressed. As always in China, it is an open question whether a directive by the central government will be implemented by provincial and local authorities.[6]
[edit] Tarim Basin
The Tarim Basin, a large endorheic drainage basins lies in a desert region in the west of China.
[edit] North China Plain
Ground water is rapidly dropping in the North China Plain. Water is being pumped both for municipal water supplies and for agriculture. The South-to-North Water Transfer Project, under construction, is projected to transfer vast amounts of water from South to North China.[7]
[edit] Water quality
There are serious problems with water pollution in China which particularly affects fish farming.[8]
