Abstract:   Floods are a permanent threat for coastal regions. Their prevention and prediction is hard. Flood protection and prevention plans are assessed by computational models. The related risk analysis communication demands simulations of accurate inundation models and their interactive visualization. In our new dutch Knowledge for Climate project we work closely together with industrial partners to find systems that support this communication. Our research focuses on fast flow simulations, their interactive visualization and steering techniques for flooding scenarios. Our goal is an interactive, realistic problem-solving environment for flooding discussions amongst stakeholders, geo-scientists and the general public. Besides, we want to find sophisticated algorithms that promote this goal. Related work in the field is done on small-scale examples and abstract computational models. We work on large-scale, high-resolution, realistic computations while maintaining interactivity. For this we use aerial terrain LiDAR point clouds of the Netherlands and most recent, complex Computational Fluid Dynamics models. The visualization system will apply a combination of new point cloud compression algorithms and spatial Level-of-Detail data structures. Fast CFD simulations will be achieved by subgridding and parallel processing of non-linear calculation models. Additionally, the integration of various geo-information (i.e. precipitation) is key to educated flooding decision-making.
