The project HORA 3 focuses on flood modelling for all rivers and streams of Austria. The results are detailed flood risk maps for different annual probabilities that will be published on the HORA Website. Using these maps, citizens can estimate the vulnerability of their buildings and premises to possible future flood hazards. The project combines methods from rainfall-runoff modelling, hydrodynamic simulation, and geospatial analytics using our software Visdom.
A major challenge lies in the processing of multiple and heterogeneous large-scale data sets to automatically derive parameters for our flood simulation engine. In our system, flood simulations can be triggered instantly without having to deal with a complex setup process. Users only have to draw a region of interest anywhere in Austria and then select a flood probability value, e.g., HQ100 (a flood that statistically occurs every 100 years). Behind the scenes, the system processes the hydrological and geospatial input data to automatically compute inflow, outflow, and interior flow conditions required by our 2D flood simulator. The simulator itself operates at interactive rates, providing immediate visual feedback on the temporal development of the flood hazard.

For many years we have been dealing with all aspects of hydrodynamic modelling. With our software viscloud we can model different scenarios and also offer this as a service.
We create a digital twin of a community and simulate weather events to identify high-risk buildings and infrastructure vulnerabilities.
The goal of HORA 3D is the development and maintenance of a publicly accessible web application for object-related visualization of the results of the HORA 3 research project.
viscloud's hydrodynamic simulations provide precise water level predictions at any point on a water surface in the "PegelAlarm" app.
Practical flood management with decision software viscloud.
Decision support system for floods and inundations for the trading district of Shenzen, China.
Flood protection through simulation and visualization: Reducing the effects of floods and communicating measures to the public.
