Hurricanes are a major cause of natural hazards in many coastal cities around the world. The use of hydrodynamics models to predict hurricane storm surge is gaining importance to support planning, damage assessment and evacuation. The ADvanced CIRCulation (ADCIRC) for coastal circulation and storm surge is a FEMA-accepted model. This paper presents ArcADCIRC, a geodatamodel that serves as a unified repository data model for hurricane storm surge (based on the ArcMarine and ArcHydro) and the GIS toolbar, that is programmed using Python and ArcObjects for ArcGIS10, developed to: 1) pre-process input data (finite element grid, manning's N extraction, etc.); 2) post-process model outputs for ADCIRC simulations (Time series display for monitoring points, time aware water level layers and cross sections, velocity vectors, coastal flood zones delineation); 3) Construct control files for Linux based MPI and run the windows version. A case study was developed for Corpus Christi, Texas.
