摘要

基于地理信息系统和遥感技术的水文模型集成系统将成为未来水文循环过程研究的发展趋势。基于HEC-HMS水文模型系统

采用多种方案对位于汉江上游的褒河流域进行了降雨径流模拟。研究结果表明:基于DEM、遥感影像和土壤资料

并结合GIS技术推求反映流域下垫面特征的关键水文参数的方法可以与HEC-HMS水文模型系统很好地耦合。该模型对于我国湿润、半湿润山区的次洪模拟具有较好的适用性。

Abstract

The integration of hydrological model system with GIS and remote sensing technology will be the prevailing trend in the study of hydrological cycle or processes in the future.The main purpose is to simulate the productive mechanism of runoff over the Baohe catchment located in the upstream of the Hanjiang River using hydrologic modeling system HEC-HMS

which includes several kinds of modules.Then DEM

soil data

landuse and landcover are processed synthetically using Geo-HMS(extended module of HEC-HMS)

which can be embedded in ArcView3.2 software

and some important parameters in this hydrologic model system could be gotten.In succession

a sort of watershed modeling scheme with network elements is established after selecting and integrating the simulated algorithms of each hydrologic process.The result shows that the simulated flow agrees well with the observed flow at the Jiangkou station

the outlet of the Baohe catchment.
