Slug additions are often the most accurate method for determining discharge when traditional current meter or acoustic measurements are unreliable because of high turbulence, rocky streambed, shallow or sheet flow, or the stream is physically inaccessible (e.g., under ice or canyon walls) or unsafe to wade (Zellweger et al., 1989, Kilpatrick and Cobb 1984, Ferranti 2015). The slug...

Landslides hazards pose a serious threat to people and infrastructure in the Federated States of Micronesia (FSM). To develop a comprehensive understanding of the landslides hazards in FSM, the USGS-USAID Landslide Disaster Assistance Team (LDAT) has put together landslide inventories for each state using satellite imagery. Mapping was done using RGB satellite imagery from Maxar, Planet...

For designing buildings and other structures to safely resist earthquakes, the 2009 National Earthquake Hazards Reduction Program (NEHRP) Recommended Seismic Provisions and the 2010 American Society of Civil Engineers, Structural Engineering Institute (ASCE/SEI) 7 Standard contain maps of Risk-Targeted Maximum Considered Earthquake (MCER) spectral response accelerations, Maximum...

Dataset includes: Bird body weight, Number of seeds dosed per day per bird,amount of pesticide dosed, pesticide residues on seeds, weight of treated seed dosed per day, weight of fecal sample for each sample, residue analyses of fecal samples, the weather conditions during the two weathering periods

Data shows CH4 fluxes from the upper portion of cypress knees across various climate and flooding gradients of the North American Baldcypress Swamp Network in the Mississippi River Alluvial Valley. Climate data in the form of temperature, relative humidity, barometric pressure, and precipitation 3-days leading up to sampling date are also included. There various forms to calculate fluxes...

In 2023, the U.S. Geological Survey (USGS), in collaboration with the Cook County Bureau of Technology (BoT), conducted comprehensive hydrographic and water quality surveys, along with activity and disturbance assessments of 58 total waterbodies encompassing lakes, rivers, and canals within Cook County, Illinois. These surveys and assessments describe the bathymetry, water-quality...

This data release compiles Uranium-series (U-series) data and descriptive collection information (such as sample/core identifier, location, elevation, etc.) for late Pleistocene coral subsamples from coral-reef cores previously collected throughout the Florida Keys by U.S. Geological Survey (USGS) researchers. The samples were collected under scientific research permits from the Florida...

This data release contains channel cross sections of the Nooksack River near North Cedarville, WA, collected during routine streamgaging and discharge measurement efforts at USGS streamgage 12210700. All cross sections were collected using an acoustic doppler current profiler (ADCP) from the downstream side of the Highway 542 bridge. Raw ADCP measurement data were processed using a...

This data release contains a comma-delimited ascii file of seven same-day, discrete discharge measurements made at sites along selected reaches of Waikoloa Stream, Hawai'i on May 23, 2024. These discrete discharge measurements form what is commonly referred to as a “seepage run.” The intent of the seepage run is to quantify the spatial distribution of streamflow along the reach during...

Between April and August 2009 four water samples were collected from the outflow channel of Old Faithful Geyser in the Upper Geyser Bain, Yellowstone National Park. The samples were collected during the main phase of the eruptions when water flow was at maximum rate. In addition, two samples of stream flow were collected in November 2016 from the Firehole River near the U.S. Geological...

Seventy-five steady state two-dimensional groundwater flow (MODFLOW-6) models of the shallow groundwater system were developed to map depth to water and estimate effective surficial transmissivity for the contiguous United States (CONUS). The models were driven by spatially-distributed recharge estimated by Reitz et al. using average water budget information for 1985-2015 and calibrated...

A previously developed steady state three-dimensional groundwater flow (MODFLOW-2005) and advective transport (MODPATH6) model was used to examine subsurface nitrate transport to wells and receiving streams in two subcatchments contributing to the Upper Chester River, Maryland. Multiple scenarios of flow and transport parameter fields (recharge, hydraulic conductivity, and porosity) were
