Development of Resident Participation-Type Slope Measurement/Monitoring System in Mountain Region

In this paper, the authors proposed the “resident participation-type slope measurement and monitoring system” to detect the premonitory symptoms of sediment disasters in the mountainous area (Takasu Town, Fukui City, Japan). The key concepts of resident participation-type slope measurement/monitoring are (1) visualization, (2) daily routine, and (3) voluntary/proactive involvement. The residents will not only monitor the danger slopes and notice unusual events, but also try to establish a system to grasp the slope deformation/displacement quantitatively. For this purpose, some different types of sensors based on the on-site visualization (OSV) concept were introduced to the dangerous slopes and retaining walls selected by the residents and geotechnical experts. The OSV sensors are low cost and visually excellent measuring device with simple measurement principle. Further improvements of measurement and recording methodology are required to increase the participation of residents to the slope measurement and monitoring.
