BUILDING BIG: Dams

Why do some dams fail? In any case, how much water can you put in the dam? Look at these dams and find out:

In the US, the era of dam construction ended about 30 years ago. This is mainly because most of the best dam sites are being used and awareness of environmental issues related to dams is increasing. In developing countries, construction of dams has just begun. Latin America, Africa, China, Southeast Asia and Eastern Europe Because the population of the 6.7 million people population is sparse, the inland Laos is often seen as a passive victim of Chinese expansionism, which is rich It is the source of raw materials and the desire of a large neighbor. And the virtual track will be parked on the way to Thailand and the prosperous country of Southeast Asia. Already 41 kilometers of Kunming - Vientiane railway, China seems to be interested now

Indeed, local governments and state governments do not undertake the work of dam construction. However, through municipal planning and delegation, as well as regional environmental supervision responsibilities, they can shift the paradigm from batch services to distributed water collection, processing, use, and reuse, and will continue to You should continue. Imagine using this method to build Century City **, Parklands, countless state-owned housing projects, and all the other large-scale new developments (mansions, areas, and landfills). We will make most of the subway (at least in winter) "out of the net" and reduce dependency on stress and mass service.

In addition to building comfortable homes for families and friends, they play a natural role in building dams. Wetlands rely heavily on Beaver Dam over most other environments. They suffered from urban development and pollution in the United States, but wetlands have various animal species. Non-profit organizations specializing in Beaver claim that nearly half of the endangered species in North America are dependent on wetlands. Wetlands also absorb large amounts of water, offset the effects of heavy rain and prevent potential flooding. In addition, Beaver Dam functions as a natural filter to prevent deposits and toxins from flowing into streams and oceans.
