Three Gorges Dam success socially and economically, with the design of state-of-the-art large turbines, and a move toward limiting greenhouse gas emissions. However, the dam flooded archaeological and cultural sites, displaced some 1.3 million people, and had caused significant ecological changes including an increased risk of landslides. The dam has been controversial both domestically and abroad. A large dam across the Yangtze River was originally envisioned by Sun Yat-sen in "The International Development of China", in 1919. He stated that a dam capable of generating 30 million horsepower (22 GW) was possible downstream of the Three Gorges. In 1932, the Nationalist government, led
Three Gorges Reservoir Region 300–340 days. The annual runoff flow at the site of the dam of the Three Gorges Project is 451 billion m³ with the annual sediment discharge of 530 million tons. The Three Gorges abounds in water resources, ecological resources, tourism resources, and the resources of some ores, which have a great potential for exploration. The Yangtze River flows through the Three Gorges Reservoir Region with the good conditions for water transportation and the water-resources development. The potential installed capacity of hydropower can be about 30,000 MW in the Three Gorges Reservoir Region where the water resources are the most abundant
