SC Flood Inundation Mapping

The overarching objective of this project is to apply an innovative solution to utilize the HEC-RAS 2-Dimensional Rain-On-Grid modeling software to provide real-time inundation maps for South Carolina and SCDOT by leveraging existing data from two of the HUC 8 watershed basins in SC. This modeling software has been previously tested in real-time during a real-word disaster scenario that impacted sizable portions of the coastal region of SC. This research will develop methods that will incorporate a more comprehensive approach over a much larger footprint than what is being attempted by other entities to predict which bridges and roads will be inundated and need closure to ensure public safety during large-scale flood events. The inundation maps will be accessible via a password-protected website administered by SCDNR. In addition, the model will be able to be used as a planning tool for resiliency analysis for existing structures and future projects.
