The water level control plan is an important problem of getting more benefits of cascade reservoirs. Especially to reservoirs with large regulating capacity, the rationality and effectiveness of water level control plan under jointly operation determine the comprehensive benefits of cascade reservoirs. In this paper, the cascade reservoirs in lower reach of Yalong River are taken as a case study. Optimal operation model of the cascade reservoirs is built and a new approach named double progressive method (DPM) is proposed and applied. The impoundment starting time and minimum water level are two key problems of water level control plan. By solving the two problems and taking the results as foundation, the optimal water level control plan of Yalong River lower reach cascade reservoirs under different runoff frequency is concluded. The conclusion and water level control plan of this paper can be references for real operation of cascade reservoirs in lower reach of Yalong River. [ABSTRACT FROM AUTHOR]
