The Study on Meteorological and Hydrological Forecasting Model of Qingjiang Shuibuya Reservoir

With 52 automatic rainfall stations’data of Qingjiang basin,process surface-rainfall,rainfall duration and consecutive days without rain based on the 49 processes of heavy rain from 2007 to 2010,a model of short-term forecast for the peak flow of Qingjiang Shuibuya Reservoir was established.According to the national industry standard the precision of the model was judged Class B,and the model could be applied to operation forecast.During the real-time forecast,using the model with rainfall predicted value,it can extend the forecast lead time of flood peak.In 2011,the effect of forecast experiment is better and is a good reference to schedule work of the reservoir,like flood discharge,water storage,and power generation.
