| Abstract: | The character and classification of stream runoff nodes was analyzed in the paper,and the method to extract stream network based on ArcGIS was discussed.Then,a method to extract stream runoff nodes based on geometric network was brought forward.It was proved that this method was simple in principle,easy in operation,and the result was in accordance with the relief reality.These methods could be widely used in the distributed hydrology model and other researches. |
| Keywords: | stream runoff nodes geometric network DEM |
