Destination Earth On-Demand Extremes Digital Twin is the initiative of European Commission whose aim is to provide forecasts of extreme weather events in high spatial resolution. Such forecasts are essential inputs for various applications, including hydrological models used in flood forecasting. Nine countries have been involved in testing high-resolution meteorological forecasts in national hydrological forecasting systems by analysing a specific historical flood event. The Slovak case study dealt with the analysis of the May 2021 flood in the upper Hron River basin in central Slovakia. The HBV and HEC-HMS rainfall-runoff models used in the national hydrological forecast service were modified to allow comparison of their outputs between both the current and new configurations. The results demonstrated the sensitivity of the models to the input data, in particular the precipitation volume, the redistribution of precipitation in the catchment, and the initial conditions prior to the simulation of the flood wave. Even though the new model configurations did not show significant improvement in terms of standard statistical metrics on the 3-year period, regression analysis revealed better simulations of higher flows.
