Reliable estimates of expected extreme flood events are required for design and operation of vital infrastructure such as flood defences, bridges and culverts, and also for more general flood risk management and planning, e.g. emergency planning, flood risk mapping, and for defining flood insurance premiums.

Most of the methods routinely used for flood frequency estimation are designed to: i) be conceptually simple and easy to use, ii) not require too much in terms of volume and formatting of input data, and iii) make predictions based on an underlying assumption of a stationary environment.

The physical mechanisms responsible for flood generation vary through-out Europe, but do not align with national and administrative borders currently determining the choice of method for flood frequency estimation. In addition, a myriad of methods for flood frequency estimation are available, and often individual institutions and scientists have developed their own particular tools.

European scale flood research projects funded under the EU Framework programme include projects on hydraulic aspects of river basin modelling (RIBAMOD, IMPACT and FLOODSite), mitigation and vulnerability assessments (RIVERLIFE ,MITCH), large scale impacts of climate change (MICE), and flood frequency analysis using historical and paleoflood information (SPHERE).
