Advanced Monitoring System on Debris Flow Hazards

Abstract

The debris flow had become a common natural hazard in Taiwan for past years. The Taiwan government had contributed a lot effort on debris flow hazard mitigation. The monitoring system of debris flow had played an important role in the debris flow disaster response. In this chapter, the debris flow monitoring system in Taiwan was well described, including the monitoring sensors and instruments, communication methods, data collection, and power system. Different types of monitoring stations were also introduced, including the advanced monitoring device, the portable unit. A case of debris flow in Shenmu, Taiwan, was addressed to explain the debris flow monitoring system and the results. With the advantages from the intelligent debris flow monitoring system, the debris flow disaster response has been enhanced in terms of efficiency. The advanced monitoring system has been a great benefit to the public regarding debris flow warning and hazard prevention.
