Debris flow hazard evaluation based on BP neural network

CHEN Hua1 SHANGGUAN Yun-long2(1.Jilin Chengyuan Institute of Design Co.,Ltd,Jilin 132013,China;2.Jilin Traffic Science Graduate School,Changchun 130012,China)  
This paper used 8 debris flow catchments as examples,the gradient of the main channel,loose material volume per area,slope gradient,ravine density,vegetation coverage,supply ratio were selected as influencing factors.BP neural network was used for the debris flow evaluation.It is drawn that BP neural network theory is simple and rational to study the debris flow hazards.
