Decision support in the environmental domain is often based on simulating phenomena of interest by means of numerical models. For example, disaster management relies on the simulation of catastrophes such as floods or droughts to estimate the local risk and damage. Construction planners employ agent-based simulations to investigate possible evacuation procedures. A simulation is an intricate computational process, and its complexity must be hidden from the user behind intuitive visual interfaces. To achieve this, we aim for a tight integration of simulation, analysis, and visualisation in the software Visdom.

The key to successful decision support is the ability to test and explore alternative options. Users are able to pose "What if" questions to the system, for example, "What happens if a levee breach occurs?", "Does it make sense to install mobile protection barriers next to the hospital?", or "Can we guarantee the completion of all barriers in time if we employ 30 workers and two trucks?". In Visdom, the synergy of modules for simulation, analysis, and visualization provides the user with the answers to such questions. In dedicated visual representations, users can observe the effects of their decisions, for example, a flood extent or an expected damage to important infrastructure.
Our most advanced application concerns flood and stormwater events. It uses a GPU-based inhouse 2D shallow water solver in combination with a sewer network simulation to model different hydrodynamic phenomena. Apart from that, we are working on the integration and coupling of simulation models for rainfall-runoff computation, logistics, and agent-based models for pedestrians and traffic to provide broader applicability of our generic decision support in the environmental domain.
