Hydrodynamic Modelling as a Service
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.
Portfolio Modeling Options
With our software Visdom we can model different scenarios:
- River floods
- Heavy rain
- Coupled sewers
- Designing short-term protections
- Designing long-term protections
- Protection failures - evolving dike breaks
- Protection failures - overtopping and breaches of mobile walls
- Modelling uncertainty with simulation ensembles
- Evacuation scenarios
This video demonstrates the versatile river flood modelling capabilities of Visdom. Historical floods are reconstructed and multiple possible future scenarios are quickly evaluated. River boundary conditions are automatically derived from hydrological input parameters — users only have to select a region of interest. The integrated analysis components compute damage and risk on-the-fly. Interactive tools enable an in-depth visual analysis of the simulation results.
Visdom supports the fast simulation of pluvial floods, displaying the results on-the-fly in unprecedented 3D visualizations. This video showcases heavy rain scenarios in urban and rural regions. On the basis of high-resolution terrain models, we evaluate the surface run-off and the associated risk at interactive rates.
For a thorough investigation of flood and heavy rain events in urban regions, underground flows must be considered. Visdom comprises a two-way coupling of the surface run-off simulation with underground pipe networks, allowing for stress-testing the capacities of sewer networks and for evaluating risks associated with sewer failures such as overflow scenarios or pipe clogging.
Visdom enables the user to test different protection measures to mitigate the adverse effects of extreme weather events. Our decision support concept is based on a simple setup and fast simulation of alternative options. This video demonstrates the basics using the example of designing sandbag barriers to protect the area around a hospital.
Visdom enables the user to test different protection measures to mitigate the adverse effects of extreme weather events. Our decision support concept is based on a simple setup and fast simulation of alternative options. This video demonstrates the basics using the example of protecting a city from possible future river floods. The user draws a combination of a retention basin with mobile walls to minimize the damage to the infrastructure.
To evaluate the rest risk and to simplify the creation of special protection plans, Visdom supports the modelling of protection failures. This video shows large-scale simulations of dike breaches. The geometry of the dike breach is changing over time.
To evaluate the rest risk and to simplify the creation of special protection plans, Visdom supports the modelling of protection failures. This video shows possible failures of mobile walls in the city of Cologne, Germany. The walls can be overtopped if the water level rises above the protection level. A mobile wall breach can develop at any location, e.g., due to the impact of driftwood.
A deep understanding of uncertainty plays an important role in prediction and risk analysis. Visdom models uncertainty via the concept of simulation ensembles. These are large groups of scenarios corresponding to varying parameter ranges. This video shows how an ensemble simulation is set up and analyzed to study uncertain dike break events.
With VISDOM one can also simulate the impact of tsunami wave hitting a city. Seen here is a Chinese city impacted by a tsunami.
Visdom employs an agent-based simulator to model evacuation scenarios. The concepts for risk analysis and the design of measures are similar to the mechanisms used in the hydrodynamic modelling cases. This video shows the evacuation of an outdoor concert venue and different evacuation scenarios for a large office space.
