Cascade project of Three Gorges and Gezhouba is an important project for downstream Yangtze river basin, and operation jointly of cascade project of Three Gorges and Gezhouba is not only the basic and example of sustainable water resources utilization of downstream Yangtze river basin, but is the necessary condition to realize overall hydrology compensation, storage compensation, power compensation and improve reliability of systems and synthesized benefits, thus, it is necessary to learn the status and progress for discussing the problem of hydrology, operation, and so on which the operation techniques integration on cascade project of Three Gorges and Gezhouba involves. On the basis of discussing on significance of operation techniques integration on cascade project of Three Gorges and Gezhouba, relative research of automatic measure and report system of meteorological water information, cascade operation of river basin, dynamical control of water limited level during flood season, ecological operation for huge reservoir and examination of special huge hydropower are analyzed and the problem need to solve quickly are pointed within this task which give the guidance for this task and the same study and practice.
