Data and hydraulic models at selected dam-removal and culvert-retrofit sites in the northeastern United States

This dataset contains U.S. Geological Survey (USGS) developed hydraulic models, USGS developed hydrology data, US Fish and Wildlife Service (USFWS) supplied data (topography/bathymetry and structure data for pre removal conditions), and USGS field surveyed data at nine dam-removal and culvert-retrofit sites in the northeastern United States (Olson and Simeone, 2021). The hydrology, the USFWS supplied and USGS field data 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 both the pre- and 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 HEC-RAS hydraulic models include data for the models and model output files.
This data release consists of four child items and a file listing the name and location of each of the modeled areas and purpose of each model (file “Site_Details.xlsx”).
