The lower the normal water level is, the better it will be for migration, sediment ecology and environment, and investment. That's why./Why is this?

in the demonstration stage of the three Gorges project, there were many different schemes about the normal water level of the three Gorges reservoir, ranging from 15 to 2 meters. The higher the normal water level, the greater the benefits of flood control, power generation, shipping, etc., but the greater the inundation loss and the number of immigrants, the more difficult it is to deal with sediment deposition, the greater the investment and the longer the construction period, and the greater the adverse impact on ecology and environment.

The Three Gorges Project is a super-large project that attracts worldwide attention. Its inundation involves a wide range, great inundation losses and a large number of immigrants, which is unprecedented in the construction history at home and abroad. According to the statistics in 1992, according to the normal water level plan, the Three Gorges reservoir area is flooded in 21 counties, requiring 84, migrants. Considering the natural population growth rate and other factors, 1.13 million people will be relocated when the project is completed in 29. Therefore, some people say that the key to the success or failure of the Three Gorges Project lies in immigration.
