| Summary: | The paper is aimed to characterize the relationship between the landslide events and the
critical rainfall intensity-duration from the rainfall analysis. In this study, 10 landslide events
that occurred in Ranau, Sabah area between years 2007 to 2015 were investigated and
analysed using rainfall threshold based on soil water index (SWI) method. The analysis
results showed that both short-intense rainfall (i.e., 1-day) and prolonged antecedent rainfall
(i.e., 14, 30-day) played a significant role of the landslide initiations in Ranau, Sabah area.
Overall results indicated that this method could simulate the rain infiltration response by the
level of soil moisture in the area of landslide. |
