Slope Hazard & Risk Assessment along State Road in Sarawak

The Jabatan Kerja Raya Sarawak (JKRS) initiated a project to assess the slope features, hazard and risk along Jalan Raya Negeri Sarawak at Sri Aman and Betong area, which traverses through challenging mountainous terrain. Remote sensing technology was used for a full evaluation of linear based assessment along roads. Landslide causal factors were used to formulate the hazard and risk model.

The assessment involves the application of RS, GIS, detailed inspections of the slopes along the road, followed by conceptual design for mitigation measures was proposed for all Very High-risk rating locations
