Abstract

The DAMOCLES project has developed and applied new quantitative technologies for debris flow and rockfall hazard assessment, impact prediction and mitigation studies. Three models provide an integrated approach to debris flow hazard assessment: a statistical multivariate model and GIS for mapping debris flow susceptibility at the regional scale (1000 km2); a small basin (10 km2) debris flow impact model for predicting fan sedimentation; and the existing SHETRAN landslide model for predicting debris flow occurrence and sediment yield at the basin scale (500 km2). In addition the STONE model has been developed to assess rockfall hazard at scales ranging from the hillslope to the region. A supporting field programme in the Spanish Pyrenees and Italian Alps has provided new quantifications of debris flow characteristics, databases for running the models and improved techniques for assessment mapping and data analysis. The close involvement of end-users has ensured the practical relevance of the project technologies and facilitated their transfer into the public domain. © 2003 Millpress.
