This book represents a capitalisation of knowledge from previous EC research projects in the field of Natural hazards and, in particular, the CADZIE and SATSIE projects addressing the problem of avalanches. It is about the design of dams and other protection measures in the run-out zones of wet- and dry-snow avalanches. The book summarises recent theoretical developments and the results of field and laboratory studies, combining them with traditional design guidelines and principles to formulate design recommendations. The findings of the book are relevant to avalanche experts and authorities concerned with protection measures and risk management.
