Especially cities and municipalities suffer from the consequences of climate change: heatwaves alternate with extreme weather events such as heavy rainfall and floods. Although climate change is a global problem, local interventions in urban areas, in particular, have great potential for rapid relief. The increasingly frequent and heavy rainfall can not only be tamed by innovative urban development concepts like Sponge City but also be made productive. With our unique digital simulation and visualization application Visdom, we solve real problems caused by too much water. Often, even simple measures such as green roofs or rainwater-fed biotopes improve the situation.
One of the most negative effects of the climate crisis is an increase in flood disasters as a result of heavy rainfall events. For this reason, it is essential for cities and municipalities worldwide to be able to get a precise understanding of which infrastructure is particularly at risk and which structural or landscape planning precautions should be taken, for example, to avert flooding. Our simulation software Visdom offers the ideal support for this: digital twins of entire cities and regions are created from real data, in which all kinds of extreme weather scenarios can be simulated at speeds previously unheard of on the market. This makes it possible to digitally determine the most suitable measures - from constructional modifications to the most suitable locations for protective barriers, to the best evacuation routes - and, based on this information, to decide which solutions will be implemented in real life.
As a service for communities, we offer in cooperation with RIOCOM - Engineering Office for Cultural Technology and Water Management - customized disaster control planning for extreme weather events. We create a digital copy of a municipality and simulate a variety of scenarios: What happens if streams overflow their banks or canals can no longer cope with wastewater. Based on the simulation results, suitable protective measures are defined, a contingency plan is drawn up or local emergency personnel (e.g. fire brigade) are advised.
To make cities and regions more resilient, i.e. more resistant and robust against floods or heavy rainfall, risk analysis is a key element. During a successful risk assessment, weak points are identified, hazard zones are calculated and the risks quantified. In this context, we offer detailed calculations in the micro and macro range for various hydrodynamic events, for small municipalities or large areas, for entire regions or even countries. In addition to the analysis itself, Visdom offers easy-to-understand visualizations, which are ideally suited for preparing the public and emergency personnel for possible extreme weather events in advance.
In the project HORA 3, which we are implementing together with the TU Vienna for the Federal Ministry of Agriculture, Regions and Tourism and the Austrian Insurance Association, we are dealing with flood modelling for all rivers and streams in Austria with a catchment area larger than 10 km². The results are detailed and easily understandable flood risk maps for different annual rainfall probabilities, which will be made available to the public at the end of the project, so that everyone can assess the risk situation for their homes in case of future flood events.
Even the best prognosis cannot prevent the event from occurring, but it can help considerably to get an idea of the extent and scope of a storm or flood. Flood warnings have a long tradition in Austria, in the last century fast riders informed the public when river levels rose alarmingly and cities were acutely threatened by flooding. Today's state-of-the-art flood protection includes precise flood prediction. We can carry out these project-related or based on any GIS coordinates. This is important, for example, for personalised forecasts, but also for marine navigation.

Renewable energies, such as hydropower, are an essential backbone for a climate-friendly future. To enable better real-time monitoring and thus maintenance of hydropower infrastructure, innovative digital hydropower twins are being developed in this project.
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.
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.

Digital representations of the real world and digital twins are becoming increasingly important for planning, situation assessment and decision-making.
