| 摘 要： | 利用测雨雷达结合稠密和稀疏雨量站网估计流域降水分布,将小同方法获得的降水分布输入降水径流模型TOPMODEL,模拟1998,1999夏季GAME/HUBEX试验区梅山和鲇鱼山集水区的径流,并与实测径流进行比较和分析,结果表明:1)雷达结合集水区内雨量计网模拟径流的精度优于传统的用稠密雨量计网模拟径流的精度;2)利用雷达结合集水区外相对稀疏的雨量计网模拟径流的精度和用集水区内稠密雨量计网模拟径流的精度相当,显示了测雨雷达在径流模拟和洪水预报中极大的应用潜力。

| Abstract: | The conceptual rainfall-runoff model TOPMODEL is used to simulate runoffs of the Meishan and Nianyushan catchments during the summers of 1998 and 1999 in the GAME/HUBEX (GEWEX Asia Monsoon Experiment/HUAIHE River Basin Experiment) project. The rainfall distributions are estimated by weather radar and rain gauge networks according to different methods. Observed and simulated runoffs are compared and analyzed for both catchments. Results show that(1) the runoff of the catchment is best simulated by radar data combined with rain gauge network data from inside the catchment, and (2) the rainfall estimated by radar adjusted by a few rain gauges outside the catchment can be used to simulate runoff equally as well as using the dense rain gauge network alone. |
