SOURCES VOLUME MODEL AND ACCUMULATION EVOLUTION OF DEBRIS FLOW IN WENCHUAN EARTHQUAKE REGION
摘要
Abstract
After the 2008 Wenchuan Earthquake,debris flow disasters were strong.So far,many rainfall processes had happened.How can we accurate analyze the accumulation evolution of debris flow.We should make sure the volume of sources.In order to solve the question,5 debris flow gullies were chosen along Minjiang River as a research area near Yingxiu.First,using field survey,we got the volume and area of 167 sources.Then analysising the relationship between the volume and area,we got the volume model.Last,we verified the model by 48 sources. Through the remote sensing interpretation,combining with volume model,this paper expounds debris flow source activity in the studied area.关键词
