IDENTIFICATION OF SLOPE FAILURE USING 2-D RESISTIVITY METHOD

A study has been conducted to analyze the slope failures features and the factors that contribute to the landslide occurrence at Restu, Saujana and Tekun (RST) Complex, USM by using the 2-D resistivity method. Five survey lines were conducted with 100 m length and 2.5 m minimum electrode spacing....
