Hydrology 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) developed hydrology data at nine dam removal and culvert retrofit sites in the northeastern United States (Olson and Simeone, 2021). Hydrology was estimated for the river reaches of the hydraulic models. The hydrology estimated generally included flood flows for the 50-, 20-, 10-, 4-, 2-, 1-, 0.5-, and 0.2-percent annual exceedance probability, and mean monthly streamflows. The hydrology 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 [...]
