Abstract: By using hydroinformatics technologies to deeply analyze and trace the causes of the “23∙7” catastrophic flood occurred in Haihe River Basin, to detect the weak points of flood defense and to give technological suggestion for the future flood management in this region. The key issue for assess this catastrophic flood is how to deal with the big mount of hydro- data and set up the models to represent the progress of this disaster and to evaluate the impacts of flood defense measures. A big mount of data including hourly records in 5302 rainfall stations, 1385 hydrological stations, 1239 reservoirs and high resolution topography data and 3D hydraulic structures information has been analyzed and applied for setting up the distributed hydrological model of 173 computation unit which covers around 23,000km2 area. Moreover, 8 high resolution 2D hydraulic models have been also created for represent the flow movement in the floodplain area. At the end, all those data and modelling results have been integrated into a digital twin platform of Haihe river basin.
