基于DEM的山洪灾害区小流域划分
Partition of Small Watershed on Mountain Torrent Disaster Area based on DEM
摘要
Abstract
Mountain 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 feature extraction of small watershed is the basic work of mountain flood disasters early warning system. Combined with the actual situation of watershed, the article discusses the method of classification and feature extraction of small watershed using DEM technology, and proposes the technology of dividing small watershed torrent disaster area. It gives the technical foundation for flash flood forecasting warning.关键词
