A Debris Flow Hazard Monitoring and Early Warning System Based on Formation and Motion Processes of Debris Flow
Journal of Natural Disasters,2014,Vol 23,No. 03
According to the massive total volume, group-occurring debris flows in the Wenchuan earthquake stricken area, the monitoring and early warning system will be an economic and effective measure. Based on analysis of past performance of debris flow early warning and existing problems, this paper proposed a new debris flow hazard monitoring and early warning system based on the formation and motion mechanism of debris flow. The new system consists of rainfall monitoring, fluid level monitoring, pore-water pressure monitoring, soil moisture monitoring, ground vibration monitoring, and video monitoring. And the early warning levels were established after the comprehensive analysis of the threshold values of all these monitorings. It would be suitable to use this comprehensive monitoring and early warning system for protecting debris flow threatened areas in the Wenchuan earthquake stricken area.
