The planning and comprehensive utilization of Three Gorges Project

Abstract: As the most significant water project, the Three Gorges Project (TGP) was designed to take care of multiple objectives for water utilization such as flood control, power generation and navigation. The implementation of the project will improve the flood safety level of Jingjiang reach to more than 100-year return period, which will reduce greatly the flood risk at the mid-lower reaches of Changjiang River, produce huge quantity of energy for the central, east and south China, and improve significantly the navigation conditions of Chuanjiang River. Meanwhile, the operation of the TGP in dry season which will compensate the downstream water resources, will as well deepen the navigation channel and thus improve the navigation conditions in the middle river reach. With the increasing demands raised from various aspects of the society, new requirements will be made for the TGP for the purpose of harnessing, development and protection of the Yangtze River Basin. Therefore, it will be a long-term task for the operation of TGP on how to optimize the water resources utilization and implement an effective operation.
