ESP recently completed a large-scale modeling, mapping and FEMA Physical Map Revision for the City of Roanoke, VA. The purpose of this project was to modernize the modeling for an approximately 10-mile reach of the Roanoke River through the City. ESP leveraged this modeling, stream gage / forecast information to develop a state of the art, real time, flood inundation mapping and warning system for the City.The project scope included a system requirements analysis, database design, code development, deployment and training. The application extracts data from the USGS and the National Weather Service every 15 minutes. River stage, flow and forecast values are stored in an enterprise database that drives the application. Application users interact with the site via information widgets showing current and forecasts stage, flow values and interactive charts. The system includes a forecast module allowing emergency managers and other stakeholders to view forecasted inundation, impacted buildings and critical facilities by interacting with time-slider tools.
