Researching of Forecast Project of Double Mutual Inflow Reservoir Flood
Zhanghe reservoir is composed by Guan Yinsi reservoir and Ji Gongjian reservoir through semi-natural open channel. The characteristics of two reservoirs are great disparity, and inflow each other. Because of the complicated influence of transmitting water by open channel, observation error of reservoir level and calculation error of backwater storage, many flood forecast projects established in the past did not come to applied level. This text develops the yield and conflux forecast project of anti-error zoning based on analyzing characteristics of error generation of Zhanghe reservoir flood, and adopts real-time adjustment technique. It basically avoids the calculating error problem of Ji Gongjian reservoir flood. It makes the average deterministic coefficient, the qualified rate of flood peak, the qualified rate of time to peak of Zhanghe reservoir flood forecast project come to 91.09%,100%,90.91%.While Guan Yinsi reservoir flood forecast project comes to 90.63%,100%,100%,which establishes Zhanghe reservoir flood forecast project that attains first-rate finally.
