Scientific structure of the research unit and key research questions
Extreme floods are extraordinary in terms of their size, characterised by their peaks, and/or other features, such as volumes, shapes, spatial extent or seasonality which are, in turn, related to the peaks. Floods occur during events, i.e. defined periods of high river discharges. The natural way of analysing floods, therefore, is the event scale. Flood events are imbedded in a regional context of meteorological, landscape and river conditions, so a complementary way of analysing floods are space (regional) scales.

In the first funding phase, the reseauch unit analysed extreme flood processes along the axes of scales:

As an extension of the first funding phase, the second phase relies on Task Forces that concentrate on the joint methodological research on a given topic. The six Task Forces are

  • (I) Analysis of Extreme Events, Specification of Drivers of Changes and Assessment of their Regional Specific Characteristics – Data Based Approaches
  • (II) Deterministic Hydrological Models to Estimate Extreme Floods
  • (III) New Statistical Methodologies (to Specify Upper Tails in Flood Probability Distribution Functions)
  • (IV) Derived Flood Frequency Analyses: How to Combine Weather Generators with Hydrological Models to Simulate Flood Series
  • (V) Probabilistic (stylized) Hydrological Models to Generalise Flood Changes and their Attribution
  • (VI) Climate Change, Changes in Flood Types and Future Changes in Flood Probabilities.
