Abstract:
To gain the threshold of catchment area is the critical step of extracting drainage network from DEM.But this index determination were still subjective and random with no theoretical support in most studies.Taking Zagunao Drainage Basin as an example,we calculated the drainage densities of different accumulation areas with SRTM-DEM data by using the hydrology model in Arcgis followed by gaining the optimum accumulation area with the method of mean of change-point.The result indicates that the drainage density correlated with accumulation area negatively and the 8.1 km2 optimum accumulation shows more authenticity compared with the geology map of 1:500 000.It means that this kind of way can be applied to determine the accumulation area.
