Rainfall-induced slope instability is one of the major concerns in tropical regions. Many rainfall-induced slope failures were observed in lateritic soil slopes in Kerala, during monsoon seasons. In the present study, an attempt was made to investigate the factors affecting the stability of soil slopes at the onset of rainwater infiltration; and to...
Seasonal variations in the soil moisture content can result in significant changes in soil suction. Rainfall infiltration can cause loss of matric suction in the unsaturated lateritic soil. Several failures are reported in lateritic soil slopes in Kerala, associated with rainfall. Geosynthetics are generally used for improving the stability of soil...
