Abstract

The analysis of multi-hazard risk requires the use of models that are very data demanding. Data is needed of the areas that might be affected and the characteristics of the hazard, but also of the elements at risk that might be impacted, and their vulnerability. In the framework of two European projects
(FP6-PEOPLE-2006-ITN Marie curie Mountain risks and FP7 SafeLand) a training package has been developed on the use of spatial information for the assessment and management of mountain risks. This training
package explains the procedures to collect, analyze and evaluate spatial information for risk assessment from natural hazards in a mountainous environment. It aims at researchers and practitioners that have to carry out
risk assessments at a medium scale, and use the risk information in disaster risk reduction planning. The training package guides the participants through the entire process of risk assessment, on the basis of a case study
of an area exposed to multiple hazards in Barcelonnette, France. In order to achieve maximum applicability the training package is made for use with Open Source software. Three-dimensional stereoscopic image interpretation
using images downloaded from Google Earth is used to familiarize the participants with the hazard phenomena. These are then used in either a statistical or heuristic approach for modelling the initiation areas
for landslides, debris flows, snow avalanches and rockfalls. The source areas are used for run-out modelling on a medium scale using a routing-spreading model and the results are converted into impact maps. Flood hazard assessment is done using a 1D-2D flood propagation model and flood impulse is calculated for different return periods. The source maps and run-out maps for mass movements and the flood maps are then used in a quantitative multi-hazard risk assessment, by calculating the exposed elements at risk, the temporal and
spatial probability and the vulnerability of the elements at risk. Also emphasis is given to the evaluation of uncertainty in the risk assessment process. A qualitative method for multi-hazard risk assessment is also included,
using Spatial Multi-Criteria Evaluation, in which a hazard index and a vulnerability index are generated. The final part of the training package deals with the use of risk information for disaster risk management, e.g. by incorporating the risk information in preparedness planning, cost-benefit analysis for the planning of remedial measures, and land use zoning.
