One-dimensional hydraulic and environmental DNA transport models for the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee One-dimensional hydraulic and environmental DNA transport models for the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee
This dataset includes the one-dimensional HEC-RAS model calibration files and simulation input and output files for the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee. Simulation results were used as input for environmental DNA transport models.
Sediment Laboratory Quality Assurance Project Data, 1999 - 2024 Sediment Laboratory Quality Assurance Project Data, 1999 - 2024
The collection and analysis of fluvial sediment samples has been an integral part of hydrologic studies in the United States for over 125 years (Gordon and others, 2000). Accurate measurement of sediment concentrations and its movement in streams is critical to maintaining important infrastructure and habitats in the Nation’s waterways, such as impoundments and estuaries (Hudson and...
Effects of Batrachochytrium dendrobatidis and methylmercury on survival of amphibians across the United States Effects of Batrachochytrium dendrobatidis and methylmercury on survival of amphibians across the United States
The U.S. Geological Survey conducted sampling across the United States between 2017 and 2022 to assess the effects of methylmercury bioaccumulation and amphibian chytrid fungus (Batrachochytrium dendrobatidis; Bd) on the survival of amphibian species. This dataset includes detections and non-detections of Bd (obtained from DNA extracted from skin swabs) and whole-body methylmercury...
Data release of U-Pb TIMS zircon and monazite geochronology for Proterozoic rocks of the Mojave Province, California and Nevada, USA Data release of U-Pb TIMS zircon and monazite geochronology for Proterozoic rocks of the Mojave Province, California and Nevada, USA
This U.S. Geological Survey (USGS) data release presents U-Th-Pb concentrations, isotopic ratios, and geochronologic data collected by thermal ionization mass spectrometry (TIMS) for Proterozoic igneous and metamorphic rocks of the Mojave Province, California and Nevada, USA. Sample and data collection occurred by 1984 and 1990.
Fuels Data for the 2021 KNP Complex Fire in Sequoia and Kings Canyon National Parks, Collected in 2024 (ver. 1.1, January 2026) Fuels Data for the 2021 KNP Complex Fire in Sequoia and Kings Canyon National Parks, Collected in 2024 (ver. 1.1, January 2026)
Post-fire vegetation structure and fuels data are essential for understanding the recovery process after major disturbances. To meet this need, 40 plots within and around the perimeter of the 2021 KNP Complex Fire were surveyed between July 12 and July 28, 2024. Data was collected on sites previously established by the U.S. Geological Survey Kings Canyon and Sequoia Field Station, as...
Streamflow and precipitation data and characteristics of selected storms for four stream basins in West Virginia, 2017-2020 Streamflow and precipitation data and characteristics of selected storms for four stream basins in West Virginia, 2017-2020
In cooperation with the West Virginia Division of Transportation, Department of Highways (WVDOH), precipitation and streamflow were measured at four streamgages in West Virginia to compute time of concentration (Tc) and compare it to Tc estimates made using accepted methods. Precipitation and streamflow data were collected during 2017-2020. Storms were identified and classified through...
