All Data

This USGS data release represents the 1:500,000-scale geospatial data for the following publication: Eakin, T.E., and Lamke, R.D., 1966, Hydrologic reconnaissance of the Humboldt River basin, Nevada: Nevada Department of Conservation and Natural Resources, Water Resources Bulletin 32, 107 p. The data set consists of 3 separate items: 1. Depth-to-water area polygons 2.

Historical (1984-2014) Landsat-based ET maps were generated for major irrigation districts: Palo Verde and eight other sub-basins in parts of middle and lower Central Valley, California. A total of 3,396 Landsat images were processed using the Operational Simplified Surface Energy balance (SSEBop) model that integrates weather and remotely sensed images to estimate monthly and annual ET within the

This file contains 200 sets of bootstrap-estimated land-to-water coefficients from the CBTN_v4 SPARROW model, which is documented in USGS Scientific Investigations Report 2011-5167. The coefficients were produced as part of CBTN_v4 model calibration to provide information about the uncertainty in model estimates.

The data set consists of evapotranspiration (ET) measurements/estimates based on data collected at the USGS Blue Cypress marsh station 274143080424100 beginning June 1, 1995 and ending October 20, 2014. The station is located at a nearly flat wetlands site (27o 41 43 N 80o 42 41 W) within the Blue Cypress Marsh Conservation Area, Indian River County, Florida. The dominant plant cover at the study

Comprehensive sampling of peat, underlying lakebed sediments, and coexisting waters of a naturally uraniferous montane wetland are combined with hydrologic measurements to define the important controls on uranium (U) supply and uptake. The major source of U to the wetland is groundwater flowing through locally fractured and faulted granite gneiss of Proterozoic age. Dissolved U concentrations in f

Drinking water health advisories for perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), were issued by the U.S. Environmental Protection Agency in 2016 in response to growing evidence associated with negative human health effects. PFOA and PFOS are often associated with other poly- and perfluorinated alkyl substances (PFAS). There has been increasing concern for groundwater quality o

The consequence of a 1996 wildfire disturbance and a subsequent high-intensity summer convective rain storm (~100 mm h-1) was the deposition of a sediment superslug in the Spring Creek basin (26.8 km2) of the Front Range Mountains in Colorado. Changes in the superslug near the confluence of Spring Creek with the South Platte River were monitored by cross-section surveys at 19 nearly equally-space

Here we present surface current results from a physics-based, 3-dimensional coupled ocean-atmosphere numerical model that was generated to understand coral larval dispersal patterns in Maui Nui, Hawaii, USA. The model was used to simulate coral larval dispersal patterns from a number of existing State-managed reefs and large tracks of reefs with high coral coverage that might be good candidates fo
