Debris Flow Monitoring System and Observed Event in Taiwan:A Case Study at Aiyuzi River

摘要

Since 2002,the Soil and Water Conservation Bureau,which is responsible for the conservation and administrative man-agement of hillside in Taiwan,has been cooperating with Feng Chia University. Together,they have successfully carried out the establishment and maintenance of 13 fixed debris flow monitoring stations over the island and 2 mobile debris flow monitoring sta-tions. During July 2004,a powerful southwest air current brought by Mindulle Typhoon caused serious flood in central and southern Taiwan. This paper aims to describe the establishment of debris flow monitoring systems in Taiwan and the observation of the debris flow event during Mindulle Typhoon at Aiyuzi River in Shenmu Village,Nantou County by the monitoring station.
