ADPC conducted a training course on risk mapping and run-out area assessment as part of the Community Landslide Risk Mitigation Project, to which it is providing technical assistance in partnership with the Norwegian Geotechnical Institute (NGI). The four-day training course was attended by 20 members from the National Building Research Organization (NBRO) – a mandated agency for landslide risk management in Sri Lanka. Based on a theoretical description of mass movement, landslide run-out models attempt to understand the behavior of the actual flow phenomenon which helps to map landslide paths.

Participants and facilitators pause for a group photo during the workshop.


The course participants extended their knowledge on run-out area assessment, risk mapping, selection of mitigation options, and cost benefit analysis. Also, a field visit to landslide-site Meeriyabedda was organized in order to discuss technical aspects that need to be considered when conducting an on-site investigation and reporting.

The initiative, which is funded by the World Bank, will assist Sri Lanka in unifying efforts of government agencies and stakeholders to landslide disaster risk management. The program is focused on establishing a comprehensive framework and developing a long-term action plan for national landslide disaster risk management
