Do catchment characteristics drive extreme discharge tail behavior in the Meuse catchment? Insights from 1,040 years of synthetic discharge data.  Open
Understanding extreme discharge behavior is of importance for flood design and risk management. For example, estimates of large extreme discharge return periods such as the 100-year return period or higher are often needed as a basis for f…

Storylines of the impacts in the Netherlands of alternative realizations of the Western Europe July 2021 floods Open
The 2021 summer flooding was an extremely rare event, driven by precipitation extremes that exceed Dutch design levels for flood protection of relatively small rivers and waterways. However, similar events in neighboring locations cannot b…

DEVELOPING LARGE SCALE AND FAST COMPOUND FLOOD MODELS FOR AUSTRALIAN COASTLINES Open
The recent 2022 large scale rainfall events in Australia’s east coast have put in evidence the region’s vulnerability to severe flooding events. In the future, climate change and sea level rise are expected to exacerbate these vulnerabilit…
