Abstract

This paper, taking Bailianhe reservoir basin on Hubei province as an example, firstly used the method of set pair analysis to calibrate the radar estimates rainfall combined with basin rain gauge. We obtained the optimal Z-I relationship of Bailianhe reservoir. Then, it presented a method of weight calibration based on radar estimation and rain gauge, combined with the advantage of the rainfall station at grid point observations and the radar to estimate the rainfall distribution. The method was used to analyze a rainfall process on Bailianhe basin in June 2004, compared with other rainfall estimation methods at last. The results showed that this method has certain effect on improving the precision of flood forecasting.
