Methodological advances and scale issues

Recent research

Regional class of flood risk

Several project group members have worked on advancing regionalisation, interpolation and time-series analysis methods and scaling issues. For example, Sauquet et al. (2008) estimated mean monthly runoff at ungauged sites, using France as a demonstration region.

Map of river flow regime based on the twelve reference hydrographs for France (Sauquet et al.,2008).

Novel methods have also been developed to analyse:

• distribution of floods across Europe over the last 1000 years, including incorporation of historical hydrological information into flood frequency analysis (Macdonald);
• regional variability in hydrological/ basin characteristics and flood frequency for small basins in Slovakia (Solín);
• spatial variability of precipitation regimes across Turkey (Şaris, Hannah; Eastwood); and
• trends across the full range of flow duration curve percentiles for Wales and the English Midlands (Dixon, Lawler).
