The persistence of decadal periods of enhanced/reduced flood risk in
many regions in the World has recently interested the hydrologic
research community. While the existence of these oscillations seems to
be recognised, it is still unclear why these oscillations exist, i.e.,
what are the causes of these changes. The scope of this session is to
report when, where, how and, more importantly, why do decadal periods
of enhanced/reduced flood happen.
Specifically, the following topics are of interest in this session:
- Flood related data to detect/attribute flood risk oscillations
- Recent evidence on flood risk oscillations
- Historic floods and reconstruction of flood risk oscillations
- Atmospheric and land use controls on flood changes
- Flood change modelling
