| 摘 要： | 半干旱地区的特点是降水少且时空分布不均,下垫面条件也与湿润地区有很大不同,从而使洪水预报工作较为困难。其难点主要是:下渗能力分布不均;制约下渗率的表层土湿计算;河网汇流中的渗漏损失计算;降雨分布不均问题等。探讨了这些问题的解决办法。

| Abstract: | The characteristics of the semi-arid region are shortage of rainfall and the non uniformity of spatio temporal distribution.Conditions of catchment underlay differ from humid regions.It is difficult to forecast flood in the semi-arid region,which is non uniformity of infiltration capcity,computation of water content in surface soil,leakage calculation and non-unifority of rainfall.The preliminary methods for overcoming above difficulties are also discussed. |

| Keywords: | semi-arid region flood forecast Hebei model |
