Abstract: The new flood risk management in Switzerland means that residential, industrial and landscape areas must be protected in an appropriate way. An overall prevention should guarantee that damage caused by extreme events will not increase in future. Uncertainties in hydrometeorological and other input data should be reduced but taken into consideration when setting-up the flood protection concept. The remaining risk is to quantify. Environmental concerns must be included in the planning process as early as possible. The procedure used in Switzerland is described briefly in this paper. Emphasis is given to the role of hydrology in risk management.
