After repeated flood events along the course of the river Thaya in Lower Austria in recent years, which among other things led to considerable damage in the surrounding area, local decision-makers decided to become active in the field of flood protection and prevention. Twenty-four municipalities in the Waldviertel region, which lie along the Thaya River, therefore joined forces to obtain a comprehensive picture of flood hazards in the entire region and to develop holistic flood disaster prevention plans.
The expert team carried out hazard analyses for river floods and slope water discharges over an area of more than 2,600 square kilometers, an area larger than Vorarlberg. Based on real data, e.g. from terrain models or LiDAR aerial images, our long-term research partner Riocom created detailed flood warning maps with the help of VRVis software Visdom. With these maps, it was not only possible to define significant danger zones and endangered infrastructure around the Thaya, including all tributaries, but also to communicate these dangers to the general public in a low-threshold manner through the spatial visualizations and 3D animations that can be easily created in Visdom.
After more than three years of project work, during which regional stakeholders and the population were actively involved on several occasions in the development of the "Special Disaster Management Plans for Floods", the 4,200 hazard and emergency maps and 1,400 3D animations created with Visdom were handed over to the 24 participating municipalities in October 2021. Thanks to these extensive maps, which also include additional details on slope water or failure scenarios of dams and retention structures, there is now a comprehensive basis for the preparation for and the successful and safe execution of flood- and slope water-related operations.
The simulation software Visdom was used for 2D hydrodynamic modeling of the March and Danube regions.
VRVis is a leader in hydrodynamic simulation of floods, heavy rain and slope water. We created a checklist for real life emergency situations in case of heavy rain and floods.
In the fight against heavy rain, the city of Cologne relies on precautionary measures with the help of software Visdom.
We create a digital twin of a community and simulate weather events to identify high-risk buildings and infrastructure vulnerabilities.
