This project will enhance the USGS StreamStats web application in South Carolina (Phase II) by incorporating additional tools and functionality into the current (2019) application. In addition, a separate application, Floodplain Width and Indirect Determination of Extent (Flood WIDE), will be developed to incorporate functions that will provide additional tools for the SCDOT and other engineers and water-resource planners, that are currently not available in the National StreamStats application. The National StreamStats application is undergoing the development of a vetting process to aid in the determination of future products and tools to be included. Any tools mentioned herein, if not included in the StreamStats future products, will be available in Flood WIDE.
