Numerical hydrodynamic models are the basis for the establishment of flooding hazard zones, and GIS is a strong tool for geodata management. Combining both potentials are the condition for a better process support and optimization of flooding risk prevention.
The focus of this presentation is the workflow of creating an interface between an open source computational fluid dynamics (CFD) based hydrodynamic model with ArcGIS. ArcGIS is used as a preprocessing tool to create the calculation mesh and the boundary conditions for the hydrodynamic model. The scripts, written with Python, are able to transfer a digital terrain model in a 3d CFD-calculation net. Special focus will be on the advantages of the new version ArcGIS 10.
