Moisture sensing technology for assessment of rainfall-induced slope failure
Aiym Amantay, Alfrendo Satyanaga, Sung-Woo Moon, J. Kim
Abstract
The frequency and duration of rainfall are two examples of the climatic conditions that have changed as a result of global warming. According to earlier research, slope failures are more likely to happen after a protracted period of drought followed by a strong rainfall or after a long period of light rains followed by a heavy rainfall. This occurrence demonstrates the significance of slope susceptibility or hazard maps in identifying high-risk areas during periods of excessive precipitation. The stability of high-risk slopes can then be sustained before failures by designing the proper slope preventive actions. This study reviewed various moisture sensing technologies for real-time evaluation of slope collapses brought on by rainfall. A thorough analysis of various literatures revealed that capacitance moisture sensors offer the best compromise for affordable and effective early warning systems, particularly in a tropical environment.
