Three Gorges Dam was built in 1993 and completed in 2009, which is designed to serve three main purposes. Flood control, hydropower generation and navigation improvement, which is a huge advantage for the project. However, no matter how good the structure is, there will always be advantages and disadvantages.
Controlling flood is one of the most significant functions of the Three Gorges Dam, and flooding used to be a major problem for the seasonal Yangtze River. With millions of people living downstream of the dam and many large and important cities like Wuhan, Nanjing and Shanghai situated adjacent to Yangtze River, flooding control has been one of the most issues for China.
