The Design for Zhouqu Sanyanyu Debris Flow Monitoring and Early Warning System

The mitigation for debris flow not only needs engineering measurements,but also needs monitoring and early warning system,to obtain the goal of risk-reducing effectively.This paper took Zhouqu Sanyanyu debris flow as a studying case,proposed a comprehensive monitoring and early warning system,designed the rainfall monitoring sub-system for the debris flow triggering factors;the infrasound,mud level,ultra red-ray interruption,and video monitoring sub-system for the debris flow occurring and moving;the landslide monitoring sub-system for the debris flow resources;and the dam strain and stress monitoring sub-system for the debris flow engineering count measurements.Finally build up the early warning information system for the whole debris flow.
