Abstract
This study focused on the Landslide Susceptibility Analysis (LSA) of the Karak highway, which link the Genting Sempah to Bentong area, Pahang. The physical relief of the study area is largely flat to undulating and moderately rough to steep mostly. The aims of this study are to identify the landslide prone area and to produce the Landslide Susceptibility Level (LSL) map using Weighted Overlay Method (WOM) integrated with Geographic Information System (GIS) and remote sensing techniques. Landslide locations were identified in the study area from imagery and aerial photograph interpretations followed by field work observation. The topographic, geologic data and satellite images were collected, processed and constructed into a spatial database using image processing. The factors that influence landslide occurrences such as slope gradient, slope aspect, topographic curvature and distance from drainage were retrieved from the topographic database. Geomorphology, lithology and geological structure were generated from the geologic database; whereas land use and soil types from SPOT satellite data image. Several areas are considered as susceptible, such as areas of Ladang Fook Who, Kg. Temiang, Ladang Ng Chin Siu, Kemajuan Tanah Genting Pandak, Kg. Lentang, Kg. Baharu Bt. Tinggi and Ladang Pandak. To avoid or minimize the landslide occurrences, development planning has to consider the hazard and environmental management program. This engineering geological study may play a vital role in Landslide Risk Management (LRM) to ensure the public safety.
Highlights
Flooding Landslide is among the major geohazards in Malaysia
Landslide processes take place when the slope materials are no longer able to resist the force of gravity
With the growth of human population and the expansion of the scope of human’s activities in Malaysia, we find ourselves increasingly in conflict along steeply area [2]
Summary
Flooding Landslide is among the major geohazards in Malaysia. As with flooding, tsunami, siltation and coastal erosion, these have repeatedly occurred in the region with disastrous effect. Landslide is a general term for a variety of earth processes by which large masses of rock and earth material spontaneously move downward, either slowly or quickly by gravitation [1]. Such earth processes become geologic hazards when their direct interaction with the material environment is capable of causing significant negative impact on a human’s wellbeing. Landslide processes take place when the slope materials are no longer able to resist the force of gravity This decrease in shear resistance resulting in landslide is due to either to internal or external causes. Natural hazard mapping concerns delineation of pas occurrences of natural hazards such as landslide, but it includes predicting such occurrences [3]
