U.S. Geological Survey field survey data for hydraulic modeling at selected dam-removal and culvert-retrofit sites in the northeastern United States

This dataset contains U.S. Geological Survey (USGS) field survey data at nine dam-removal and culvert-retrofit sites in the northeastern United States (Olson and Simeone, 2021). The USGS field data survey are used to support the development of one-dimensional and two-dimensional U.S. Army Corps of Engineer (USACE) Hydrologic Engineering Center’s River Analysis System (HEC-RAS) models for the post-dam removal and culvert-retrofit conditions. The referenced models were used to evaluate fish passage and flood risk along the simulated reaches in the various states simulated. The field survey data consists of Global Navigation Satellite System-derived orthometric heights in the North American Vertical Datum of 1988 and projected horizontal coordinates in the North American Datum of 1983 State Plane for the respective State the sites are located in.
