This data is part of a series of inundation layers meant to correlate observations and forecasts from the river gage with a visual representation of the areas impacted by high water. The data set of flood depth grids was created from flood scenarios generated by a hydraulic model and DEM information. A grid for each stage was created and subsequently merged to form raster datasets for the main-stem Susquehanna River and backwater areas on its tributaries.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. Dewberry Engineers, Inc. conducted the hydraulic and GIS analysis to produce the inundation data. NWS provided the QA/QC review of the data. Funding was received from Susquehanna River Basin Commission for this project.
