Firstly, the flood control regulation of TGP in Sep is computed based on the analyses on the inflow in Sep and Oct, and the risk and loss on the ahead impounding scheme is calculated and analyzed. Then, the storage level, power production and releasing discharge are achieved by computing on the electricity generation model through reservoir regulation graph. Thirdly, obstruction in channel is analyzed and the problem in the Chongqing reach is more serious in 175-145-155m scheme. The sediment aggrading process and distribution on different schemes is calculated by 1-D reservoir mathematical model. The navigation benefit is computed by navigation model. Based on above calculations, the impounding time is decided by the multi-purpose decision model, and evaluate by analytical hierarchy and balance layout model. A best impounding scheme is achieved to match the requirement of flood control electricity generation and navigation et al.
