Impacts of floods in Switzerland

The project, realised in two phases, between 2004 and 2008, by a group of geographers of the universities of Geneva, Lausanne, Fribourg, Zurich and the EPFL, aimed at understanding the impact of flood events on the perception, knowledge and management of flood risk in Switzerland. The project was carried out within the framework of COST C19 Action "Proactive crisis management of urban infrastructure". Several case studies were carried out in Lully (GE), Saillon (VS), Berne and in the Thur river valley /TG/ZH). A comparison of hazard mapping policy in the cantons of Geneva, Valais and Fribourg was also realised. The main results are: (1) Flooding events provoke changes in the management of floods and crises in general; (2) Actors concerned with flood risks are numerous and varied (institutional actors – at federal, canton and municipality levels – in the water domain and other domains such as urbanism or land planning, inhabitants, NGOs, etc.; (3) perception and knowledge of risk vary from one group of actors to the other; only the specialists of floods in federal and cantonal administrations had a good knowledge of the processes before the studied events; (4) status of hazard maps and their degree of integration in land-planning instruments and procedures vary from one canton to the other. The case studies carried out by L. Thomi within the COST project (Saillon, Berne) were integrated in his PhD thesis (2010).
