Prediction of Shallow Failure on a Slope Using Volumetric Water Content Gradient Characteristics

Landslides that occur near residential regions are most commonly a result of shallow slope failure, which takes place as consequence heavy rainfall during the monsoon season, causing loss to human life and property. In this study, characteristics volumetric water content (VWC) gradient were analyzed predict failure was reproduced based on flume experiments performed at various conditions. The VWC values calculated for each measurement position depth. Moreover, occurrence nonoccurrence failures compared those an actual site did not undergo failure. Our results show probability increases with increase in value. Additionally, early warning criteria proposed by dividing range value into four stages rate rapidly increased. Full-scale simulate terms its scale, appropriate sensor installation positions effectively
