| 摘 要： | 根据广东飞来峡水库流域汇流特征,将全流域划分为5个支流,并采用求积仪分别计算各支流面积;然后用加权平均法计算各支流的面雨量,并将各支流面雨量对相应的支流面积进行积分,计算各支流体积降雨量;利用洪水过程飞来峡水库入库流量、出库流量和水库流域蒸发量对体积降水量预报结果进行验证,求出误差订正系数.结果表明:利用加权平均法计算的水库流域体积降水量,经过误差订正后,预报准确率可控制在90%左右,基本满足预报业务服务要求.

| Abstract: | According to the convergence characteristics in Guangdong Feilaixia Reservoir watershed,the entire basin was divided into five branches,the area and the area rainfall of each branch were calculated by using planimeter and weighted average method.Integrating various branches area with corresponding area rainfall,the volume rainfall over each branch was worked out.Last the error coefficient was extracted through testing the volume precipitation forecast result with the warehousing current capacity,the storeho... |
