Landslides and natural hazards represent a significant risk to the public in many countries around the world – to mitigate the impacts from these events, requires careful planning, engineering and management.

The geohazards team at GDG are ideally placed to mitigate these risks and support government agencies around the world with respect to town planning and land-use management. For example, GDG have been working for the past 12 months on a landslide risk assessment in Central America. The aim of this project was to identify those areas most susceptible to landslide events, combining the risk of landslide triggers with the potential of landslides to run-out and negatively impact on adjacent communities. The analysis considered a range of issues particular to the locality and also assessed rainfall as a trigger to landsliding.  

The team of experts from GDG included geomorphologists, geotechnical engineers, hydrogeologists and risk analysts to ensure all aspects of the landslide risk could be addressed. The approach adopted for this project involved a non-subjective scientific methodology to quantify the landslide susceptibility, hazard and risk in terms of potential losses to the local community. The output of this project is the most advanced prediction model for regional scale landslide risk calculations worldwide. The risk mapping exercise also included recommendations and actions for the national agencies and a cost benefit analysis of potential mitigation measures.
