Authors: Celso Ferreira, Francisco Olivera, Jennifer Irish

Computational fluid dynamics (CFD) is widely used to support modeling of earth systems. Applications using parallelized code running on super computers (high performance Linux clusters) can solve complex systems (e.g.: atmospherics, hydrodynamics) taking advantage of high resolution data for large computational domains. Its integration to Geographic Information Systems (GIS) is crucial to fully incorporate geospatial data in this process, analyze modeling results and efficiently share data. In this paper, we present a framework for integrating high performance computing hurricane storm surge modeling and GIS using a customized geodatamodel, automated file exchange and ArcGIS tools for pre and post processing. Recent developments also include the creation and editing of CFD finite element meshes in ArcGIS; analyses of hurricane storm surge hydrodynamics model results; and applications for coastal flood mapping. A case study demonstrating an automated hurricane coastal flooding mapping will be presented for the Texas coast.
