Discussed in this paper are various factors affecting the opportunity of sealing off the diversion tunnel of the Shuibuya Reservoir of the Qingjiang Cascade Reservoirs, including basin flood control, downstream hydropower generation benefit and flow interception time. On the basis of historical data routing and analysis, it is suggested that the diversion tunnel be sealed off in the last ten days of Sept, 2006. The proposed scheme will help reduce the flow interception time and the negative influence on the downstream, thus generating the maximum economic benefit.
