在印度甘比希里河流域 ,应用GIS技术水陆两用全能信息系统软件建立数字高程模型 ,进而建立 1h间隔的流域等流时线图 ,估算出模型参数 ,并将每组设计暴雨数据、地貌特征、初始参数代入地貌瞬时单位线模型中 ,分别考虑单峰、双峰、三峰、四峰共 4种情况计算出设计洪水过程线 ,并与其他方法进行比较。可以看到应用GIS技术较之手工方法更容易且更精确。
In the Gambicili River Basin of India, a digital elevation model was established by using the GIS-based omnipotent information system software, and then the isochronous flow diagram was established at 1-hour intervals to estimate the model parameters. Each set of design rainfall data, topography Characteristics and initial parameters into the geotechnical instantaneous unit-line model, the design flood process line is calculated considering four kinds of single peak, double peak, triple peak and quad peak respectively and compared with other methods. You can see that applying GIS technology is easier and more accurate than the manual approach.
