Abstract TV877; 降雨是驱动水文模型进行洪水预报的重要输入数据,降雨资料短缺给洪水预报工作带来极大挑战.引入边缘雨量站降雨数据,基于随机优选方法,构建优选雨量站权重改进降雨输入的新安江模型,对资料短缺流域进行洪水预测,并在石灰窑以上流域进行试验研究.与泰森多边形权重相比,优选权重改进降雨输入的产流预报精度有显著提高,率定期、验证期产流合格率分别从60％、40％提高至100％、60％,汇流预报精度略有提升;改进降雨输入后的新安江模型的优选参数更符合流域产汇流特征,提升了模型参数的合理性.所提优选雨量站权重改进降雨输入的洪水预报方法,对类似降雨资料短缺流域洪水预报具有重要的参考价值.
