| Abstract: | Flood disaster is one of the main disasters in China, flood forecasting and warning is an important non engineering measures for flood prevention, classification and characteristics of small watershed is the basic work of early warning system of mountain flood disasters. Combined with the actual situation of watershed, discussed the method of extracting the division and characteristics of small watershed using DEM technology, proposed the technology of divide small watershed torrent disaster area, give the technical foundation for flash flood forecasting warning. |
