The effective storage is 256 million m 3 (67.6 billion gallons) and the corresponding normal high water level is 111.5 m (366 ft) above sea level. The flood control storage is 457 million m 3 (121 billion gallons). The dam is made of clay and is 3,720 m (12,200 ft) long and 50.5 m (166 ft) high. The dam crest level is 120 m (390 ft) above sea ...

The same storm caused the failure of 62 dams in total. The runoff of Banqiao Dam was 13,000 m 3 per second in vs. 78,800m 3 per second out, and as a result 701 million m 3 of water was released in 6 hours, [12] while 1.67 billion m 3 of water was released in 5.5 hours at an upriver Shimantan Dam, and 15.738 billion m 3 of water was released in ...
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water, generate hydroelectric power, increase the water supply for irrigation, provide recreational opportunities, and ...
In good economic times, politicians in the US rush to take all the credit. In bad times, it’s the other party’s fault — or better yet, the Federal Reserve’s. The current state of the US ...
