Back analysis of slope failure induced by rainfall infiltration

The slope stability issues concerning rainfall induced slope failures constitute a major threat to both lives and property worldwide particularly in the tropical climate of Malaysia which is characterized by very intense and long duration rainfall. The aim of this study is to investigate landslide o...
