Using mobile sensors for in-situ monitoring of debris flows in Taiwan

The debris flow monitoring has been developed for many years in Taiwan. In the very beginning, the stable monitoring stations were set up for the monitoring mechanism. Then the mobile monitoring vehicles were developed later on in the middle stage of monitoring development. Now the emphasis of monitoring fields is on the application of mobile monitoring. There´re 14 stable monitoring stations and 2 mobile monitoring vehicles were built since 2002, while the low-cost , widely distributable WSN monitoring modules are invented in 2007 via WSN technologies. A portable monitoring station is invented to construct a comprehensive monitoring network through widely-range equipped monitoring instruments. The monitoring network can collect the real time data and analyze the energy variation before, during, and after the debris flows occurred, and it helps to build up an alert mechanism. Meanwhile, all the monitoring or alert information is released from the announcement platform in OGC-SWE standard format to enhance the efficiency of decision making in disaster mitigation.
