Reservoir Flood Forecast of NanSi Lake in China

Abstract:

Nansi lake is composed by Nanyang, zhaoyang, dushan and weishan through natural open channel. The characteristics of 4 lake 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 paper develops the conflux forecast project of anti-error zoning based on analyzing characteristics of error generation of Nansi lake flood, and adopts real-time adjustment technique. It basically avoids the calculating error problem, the qualified rate of flood peak, the qualified rate of time to peak of Nansi lake flood forecast project come to 89.3%,100%,91.3%.
