Description: This layer was created as part of a Flood Inundation Map Library developed for display within the NOAA National Weather Service's Advanced Hydrologic Prediction Services (AHPS). This data represents the potential flood extent for an elevation of 427.7 to 449.2 feet as recorded at the Susquehanna River at Sunbury (Sunbury, PA; USGS ID 01554000) streamgage for the Susquehanna River. This data is part of a series of inundation layers meant to correlate observations and forecasts from the river gages with a visual representation of the areas impacted by high water. The dataset of flood inundation areas was created from flood scenarios generated by HEC-RAS runs and LiDAR data obtained from the USGS which was processed to extract bare earth points. A shapefile of flood inundation areas for each stage was created and subsequently merged to form continuous datasets for the main-stem Susquehanna River. This data was developed to assist the public and emergency officials with planning and response to high water episodes at or near a defined National Weather Service river forecast point.
