The Three Gorges Dam ( simplified Chinese: 三峡大坝; traditional Chinese: 三峽大壩; pinyin: Sānxiá Dàbà) is a hydroelectric gravity dam that spans the Yangtze River near Sandouping in Yiling District, Yichang, Hubei province, central China, downstream of the Three Gorges.
Design. The Ertan Dam is a 240 m (787 ft) high and 774.7 m (2,542 ft) long double-curvature arch dam. The dam withholds a normal reservoir of 5,800,000,000 m 3 (4,702,137 acre⋅ft) with a drainage area of 116,400 km 2 (44,942 sq mi) and normal surface area of 101 km 2 (39 sq mi). The dam has four different ways to discharge water downstream.

The idea is to dam the Red Sea at its southern end where the Bab-al-Mandab Strait is only 29 km (18 mi) wide. Natural evaporation would rapidly lower the level of the enclosed Red Sea, by about 2.1 meters per year (6.8 feet per year).Water rushing back into the sea would then drive turbines to generate electricity. The dam would have the potential ...
The proposal's authors point out that "Macro-engineering projects of this size cause massive destruction of existing ecologies", a point emphasized by criticswho note the damage caused by current, far smaller schemes. The authors also note the benefits of the project. Besides helping to satisfy the region's growing energy needs, there are environme...

It was located 13 miles (21 km) upstream from the mouth of the Elwha River at the Strait of Juan de Fuca, and about 8 miles ...
Free-air gravity anomaly over the Chicxulub structure (coastline and state boundaries shown as black lines) The Chicxulub crater ( IPA: [t͡ʃikʃuˈluɓ] ⓘ cheek-shoo-LOOB) is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is offshore, but the crater is named after the onshore community of Chicxulub Pueblo. [3]
