As a result of climate change, the frequency of flood events is rapidly increasing worldwide. It is therefore becoming increasingly important not only to inform the public about the risks and consequences of future flood events, but also to actively involve them and promote self-protection. Showing people how they can be affected by heavy rainfall and flooding is a great help. Up to now, 2D flood hazard maps have been used for this purpose, which provide a good overview of the basic flood hazards, but do not contain detailed information about personal damages or risks for the individual. VRVis addresses this issue with HORA 3D: As the world's first 3D flood visualization based on our flood simulation software Visdom, HORA 3D is the online tool for human-centered climate communication.
HORA 3D makes flood risk comprehensible for the whole of Austria
HORA 3D works as a browser-based cloud application integrated into hora.gv.at - Natural Hazard Overview & Risk Assessment Austria - of the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management. The starting point of the individual flood risk visualization is the input of a specific address, whose building and surroundings appear within seconds as an interactive 3D visualization. In this way, users can easily - and without any prior technical knowledge - find out what their personal flood risk looks like. The selectable flood areas follow the 30-, 100-, and 300-year return periods as well as the situation of the residual risk (HQ300 without dams) and include further individual factors such as the estimated damage to the own house and property, the origin of the water and the flow velocity.

The HORA 3 project focuses on flood modelling for all rivers and streams in Austria. The results are detailed flood risk maps for different annual periods.
The Raincloud project's goal is to optimize and extend the simulation software Visdom to tackle the increasing challenges in water planning and disaster management in the face of climate change.
Heavy rainfall events are increasing throughout Europe. In the EU project RAINMAN, VRVis has developed an interactive model to visualize the course and consequences of possible flood scenarios caused by heavy rainfall for the city of Graz.
Visdom's hydrodynamic simulations provide precise water level predictions at any point on a water surface in the "PegelAlarm" app.
For many years we have been dealing with all aspects of hydrodynamic modelling. With our software Visdom 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.
