摘要: 根据辽宁多年平均降水量和径流量资料,应用距离权重反比插值法实现了降水的空间扩展;以扩展后的降水资料为基础,利用SCS水文模型建立了辽宁积涝预警系统,并在2005年8月一次强降水过程中进行了应用。结果表明:积涝预警系统能很好地模拟由于强降水而造成的积涝情况,模拟的积水范围和深度与实况基本吻合。

Abstract: In terms of average precipitation and runoff in Liaoning Province,spatial distribution of precipitation was obtained by inverse distance weighting(IDW) interpolation.Based on the spatial precipitation data,the system of waterlog forecast was founded with SCS hydrology model,and it was validated by the heavy precipitation process happened in August,2005.The results showed that this system could simulate waterlog caused by heavy precipitation very well.
