1.3 The Significance of Large Scale Dam Building The World Scenario of Dam Building Water-retaining structures, mostly in the form of dams, are indispensable in the development of hydropower to serve the purposes of domestic, agricultural and industrial consumption. As long as 3,000 years ago in the Fertile Crescent (WCD, 2000), people started dam construction
1.2 Layout and Scale of Three Gorges Project The Three Gorges Dam is a conventional concrete gravity dam that comprises three sections: one retaining dam, the intake dam, and the non-overflow dam (CTGPC, 2002). It is 181 meters high and 2309 meters long (ibid). Normal pool level is 175 meters, with the crest elevation at
