HORA 3 was commissioned by the Austrian Ministry of Sustainability and Tourism and the Austrian Insurance Association. Here different flooding scenarios are calculated for different annualities (for example for 100- or even 300-year floods). This is to be carried out for all rivers of Austria.  The results will be made publicly available through the HORA Website. The project is a cooperation of the VRVis with the Institute for Hydraulic Engineering and Hydrology at the Vienna University of Technology, and the Department of Geodesy and Geoinformation of the Vienna University of Technology
