With the rising frequency of water-related natural-hazard events such as floods and droughts, policymakers are increasingly focusing on risk management and adaptation strategies. These require not only a better understanding and use of forecasts of extreme hydrological events, but also the involvement of stakeholders in the decision-making process. The EU-funded IMPREX project has been just doing that, combining different forms of data with high-power climate models to predict and prepare for the impact of hydro-meteorological conditions.
