Rainfall thresholds for the initiation of slope failures at Jelapang and Gua Tempurung area
For countries located near to the Equator Line, slope failures always associated with the presence of high volume of water due to heavy rainfall. The objective of the study was to find the rainfall threshold that potentially trigger slope failures. These thresholds were to be used as the trigger lev...

Two (2) study areas were selected i.e. Jelapang area and Gua Tempurung area, as both have substantially large catchments areas with steep natural slopes located beyond the Right-of-Ways (ROW) that feeds into the engineered slopes along the PLUS expressway although they depicted different geology and bedrock underlying the area.
