Discharge observations are available at some stations in the North of Italy. The comparison in the following figures show that forecasts in the Po River slightly underestimated the observed peak discharge (in red), though no flood flooding was caused by the river.
On the other hand, results show a clear underestimation in smaller river basins, partly due to model resolution issues. Indeed for EFAS hydrological forecasts, no flood alert is issued in river basins with upstream area lower than 4000 km2. See for example a comparison between EFAS forecasts and discharge observations in the Secchia River (1300 km2), where severe river flooding occurred.
