Review of flooding indices : Indices applicable for a Swedish context

Flood risk indices and methods (such as flood risk maps) can be used for long-term pro-active activities like urban planning to reduce flooding risk but also for short-term action such as issuing early warnings when hydro-meteorological conditions are expected to develop in a way that could lead to flooding. There are many different flood risk indices and methods used in the world and this study aims to review and identify flood risk indices that could also be applicable for a Swedish context. Ten flood risk indices or methods were discovered through a comprehensive literature review. These are described in the report, including required input parameters, information about testing or validation of the method and finally advantages and disadvantages of the method with regards to its potential use in a Swedish context.
