- A simulation modelling to assess the influence of low intensity rainfall on landslide event was performed. The input data were provided from references of previous studies, field survey and laboratory tests. Two different rainfall patterns were applied. Those were the single event of rainstorm, i.e. one hour of 75 mm/day rainstorm and the long-sustained antecedent rainfall with low. intensity, i.e. 13 hours of 1.9 mm/day rain. This simulation shows that low intensity of long sustained antecedent rainfall can result in slope stability reduction and landslides, when the hydraulic conductivity of the slope is low (about 2.51 x 10-6 m/sec) and initial position of groundwater table is shallow (about 1 m to 3 m depth).
