Geohazard Assessment at Ringlet, Cameron Highlands

Geohazards assessment was conducted at the section of the TNB 275kV right-of-way, which was identified as requiring urgent attention following the landslide incidents. The assessment included soil investigation, geophysical seismic survey, and LiDAR acquisition. The Slope Information Management System (SIMS) was adopted to determine the hazard rating for each slope using parameters such as topography, slope geometry, and geological.

The study revealed that heavy rainfall, geomorphology, and geologic material of the area, human activities, and adverse geological features were the main contributors to the slope failures. Interim mitigation measures were proposed prior to permanent rectification, which included short and long-term solutions.
