| 摘 要： | 详细介绍了基于ArcGIS9.3平台的Arc Hydro模型的结构及使用方法,包括从原始高程数据提取河网的步骤。研究区域选取天津市蓟县的沙河流域,采用90 m分辨率的DEM作为基本地形数据,对沙河流域水文特征的提取,共生成28个子流域。分析结果表明:与实际河流水系特征基本吻合,因此应用Arc Hydro工具集划分的流域结果是合理的。 |

| Abstract: | This paper introduced the use method of the toolbox based on ArcGIS 9.3 environment for analyzing hydrological information and structures,including the procedures of extracting river network from raw digital elevation model(DEM) data and problems to be considered.Shahe river watershed locates in Ji County of Tianjin city.It was chosen as watershed characteristics from DEM with 90 m resolution and river catchment properties were collected.Arc Hydro model was used to generate 28 sub-watersheds.Compared with actual hydrological characteristics,the results are rational. |
| Keywords: | Arc Hydro model DEM hydrology analysis river network extraction Shahe River |
