Geological input for decision support system to manage the risk of disasters: A case study of Universiti Kebangsaan Malaysia

Abstract

This paper describes the use of geological information and terrain assessment in a Decision Support System (DSS) to address landslide problems in the campus of Universiti Kebangsaan Malaysia (UKM) in Bangi, Malaysia. Zones of priority were derived from systematic analysis of field data and overlays of the geological terrain map, landslide location, and various elements at-risk, using Geographic Information System (GIS). Among the criteria used to identify the zones of priority are seriousness of landslide impacts, manageability of mitigating measures, urgency in the need to resolve the problem and the potential for further deterioration. Results indicate that this geological-based DSS facilitates the Development and Maintenance Department (Jabatan Pembangunan dan Penyelenggaraan, JPP) of UKM in planning and decision-making with respect to such zones.
