The towers are 18 meters wide at the bottom, spread to a maximum width of 35 meters at the level of the upper deck, and narrow to 7 meters at the top. The water level of the rivers varies 39 meters between wet and dry seasons, controlled mainly by discharges from the Three Gorges Dam which is 570 kilometers away. At low water levels, the deck ...
The South–North Water Transfer Project, also translated as the South-to-North Water Diversion Project, [1] is a multi-decade infrastructure mega-project in China that aims to channel 44.8 cubic kilometers (44.8 billion cubic meters) of fresh water each year [2] from the Yangtze River in southern China to the more arid and industrialized north through three canal systems: [3]
The elevation of the canal bed varies from 1 m below sea level at Hangzhou to 38.5 m above at its summit. At Beijing, it reaches 27 m, fed by streams flowing downhill from the mountains to the west. The water flows from Beijing toward Tianjin, from Nanwang north toward Tianjin, and from Nanwang south toward Yangzhou.
In 1986 the first plant in Beijing to treat surface water, the 9th water treatment plant, was established to treat water from the Miyun reservoir. As of 2009, it was Asia's largest water treatment plant with a capacity of 1.5 million cubic meters per day (0.55 billion cubic meters per year).
The oldest bridge still in existence in China is the Anji Bridge, constructed during the years between 595 and 605. During the infrastructure boom of the past two decades, bridge-building has proceeded at a rapid pace on a vast scale.
The bridge runs roughly parallel to the Yangtze River, about 8 to 80 km (5 to 50 mi) south of the river. It passes through the northern edges of population centers (from west to east) beginning in Danyang, Changzhou, Wuxi, Suzhou, and ending in Kunshan. There is a 9-kilometre long (5.6 mi) section over open water across Yangcheng Lake in Suzhou.
Kublai Khan built the bridge to meet the water needs of Beijing. He commissioned Guo Shoujing to dredge the water ways and construct a bridge. During the Ming and Qing dynasties, it formed part of the route between Beijing and the Western Hills. According to legend, the Sorghum River comes from the story about Zhe Gao.
The Marco Polo Bridge or Lugou Bridge (simplified Chinese: 卢沟桥; traditional Chinese: 盧溝橋; pinyin: Lúgōu Qiáo) [1] is a stone bridge located 15 km southwest of Beijing's city center in the Fengtai District. It bridges the Yongding River, a major tributary of Hai River.
