APPLICABILITY OF THE SLOPE FAILURE DETECTION SENSORS TO THE HIGH INCIDENCE OF SLOPE HAZARDS IN BRAZIL UNDER THE IMPACT OF THE CLIMATE CHANGE

In Brazil, the slope disasters caused by heavy rainfall are frequent due to a combination of factors such as the climate change, development of suburban slopes due to the urban expansion, delay construction of the disaster prevention facilities, and less software for the disaster prevention measures. This paper reviews the actual situation of landslide disasters in Brazil and its disaster prevention measures, and summarizes the trends of slope monitoring methods implemented in Brazil. Then, analysis of their applicability to slope hazards was conducted including the slope failure detection sensors using tilt sensors. As a result, it was found that the slope failure detection sensor is almost applicable to the monitoring of the slope surface failures and the tailings dam failures. It is also expected to improve the evacuation behavior of residents.
