基于SRTM DEM的陕南汉江上游流域水文特征模拟研究
Hydrology Characteristics Simulating of Hanjiang River Upstream Basin in South of Shaanxi Based on SRTM DEM
摘要
Abstract
Investigating in Hanjiang river upstream basin in south of Shaanxi,treating SRTM DEM as basic datd,the method of extracting hy-drology characieristics information was analyzed using hydrology extension module of the software Arc CIS9.2. The flow direction,flow accumu-lation,stream network and subwatershed boundary etc.were attained.The extracting stream network validation was tested.Through comparing with the state DLG river data which upon the five levels and calculating the overlap difference of stream networks between two data,if was con-sidered that the river which upon the five level of Hanjiang river upstream basin in south of Shaanxi could be extracted based on SRTM DEM by ArcGIS software,and the hydrology characteristics information was effective.The research could provide a bais for hamessing flood and wa-terlogging and ecology planning and constuction.关键词
