Water-Related Natural Disasters: Strategies to Deal With Debris Flows: The Case of Tschengls, Italy

The chapter reports on a case study of how people and public administrations dealt in the past and currently deal with the danger of debris flow. After a brief description of main debris flow features, the time series of debris flow events and the history of training works at the Tschengls torrent are reported. Finally, a modern approach based on a theoretical background of debris flow research is described. The integral analysis allows us to assess the debris flow activity and intensity in satisfactory detail and therefore allows us to derive recommendations for structural and nonstructural measures.
