Data for Tritium deposition in precipitation in the United States, 1953 - 2012

This data release documents three Microsoft Excel tables that contain estimates of tritium in precipitation data for the continental United States. Table 1 contains estimates of tritium in precipitation for precipitation stations located in the continental United States. Measured precipitation data are formatted in regular font while correlated data are italicized. Table 2 contains tritium in...

MODFLOW-NWT model used to assess groundwater availability in the uppermost principal aquifer systems of the Williston structural basin, United States and Canada

A three-dimensional groundwater flow model was developed to characterize groundwater resources
the uppermost principal aquifers in the Williston structural basin in parts of Montana, North Dakota, and
South Dakota in the United States and of Manitoba and Saskatchewan in Canada as part of a detailed
assessment of the groundwater availability of the area. The uppermost...

Chemical and isotopic data for a study of seasonality of nitrate sources and isotopic composition in the Upper Illinois River, 2004-2008

This data release contains chemical and isotopic data used in an investigation of nitrate sources and transport in the Upper Illinois River basin. Samples (total = 445) include river water from the Upper Illinois River and its major tributaries plus urban wastewater and agricultural groundwater. Data include concentrations of nitrate, chloride, and sulfate; isotope ratios of N and

MODFLOW model used in simulation of groundwater flow and analysis of projected water use for the Rush Springs aquifer, western Oklahoma

In 2018 The U.S. Geological Survey, in cooperation with the U.S. Bureau of Reclamation
and the Oklahoma Water Resources Board, published a calibrated numerical groundwater-
flow model and associated model documentation report that evaluated the effects of potential
groundwater withdrawals on groundwater flow and availability in the Rush Springs aquifer in
western...

Data and citations describing the connections between agriculture and water quality in the United States

This U.S. Geological Survey data release provides the data and citations for selected tables and figures in “Agriculture-A river runs through it-The connections between agriculture and water quality”. This Circular is based on the National Water-Quality Assessment Project’s study of Agricultural Chemicals: Sources, Behavior, and Transport. This study focused on the c

Field spectra from the Snake River in Grand Teton National Park, WY, August 23, 2015

Field spectra were collected from the Snake River in Grand Teton National Park, WY, August 23, 2015, to support research on remote sensing of rivers. Reflectance measurements were made from a raft in the Swallow Bend reach of the Snake River using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in reflectance mode. The depth at each spectral measurement location was i

Geophysical data collected along the Quashnet River, Mashpee/Falmouth MA

Surface geophysical tools remotely sense hydrogeological properties that can control subsurface flow and water quality. There are numerous geophysical tools, for the Quashnet River work we have principally used ground penetrating radar (GPR) and electromagnetic imaging (EMI). The instruments are either hand carried or floated down the stream channel and other cross-sections of the river

DDT and related compounds in pore water of shallow sediments on the Palos Verdes Shelf, CA

For nearly two and a half decades following World War II, production wastes from the world’s largest manufacturer of technical DDT were discharged into sewers of Los Angeles County. Following treatment, the wastes were released via a submarine outfall system to nearshore coastal waters where a portion accumulated in shallow sediments of the Palos Verdes Shelf (PVS). An investigat

Metabolism estimates for 356 U.S. rivers (2007-2017): 6. Model outputs

This dataset provides complete fits from metabolism estimation models. The format is 5 files per model (text and tab-delimited files, packaged as 1 zip file per model): (1) estimates of daily gross primary productivity (GPP), ecosystem respiration (ER), and the gas exchange coefficient (K600), (2) parameters for the model overall, (3) estimates of the nodes

Probability of Streamflow Permanence (PROSPER) Continuous Parameter Grids (CPGs)

The U.S. Geological Survey (USGS) has developed the PRObability of Streamflow PERmanence (PROSPER) model, a GIS raster-based empirical model that provides streamflow permanence probabilities (probabilistic predictions) of a stream channel having year-round flow for any unregulated and minimally-impaired stream channel in the Pacific Northwest region, U.S. The model provides annual

National-Scale Grid to Support Regional Groundwater Availability Studies and a National Hydrogeologic Database

The National Hydrogeologic Grid (NHG) dataset includes a raster and vector representation of 1-km cells defining a uniform grid that encompasses the continental United States. The value of each cell of the raster dataset corresponds to the 1-km cell number defined as 'cellnum' in the attributes of the vector data. The NHG consists of 4,000 rows and 4,980 columns, numbered from the t

MODFLOW 2005 data sets for the simulation of potential increased inundation in flood-prone regions of Southeast Florida in response to climate and sea-level changes in Broward County, Florida, 2060-69

Two transient surface-water/groundwater models were developed to study the potential for increased
inundation and flooding in eastern Broward County due to changes in future climate and sea-level rise.
These models were constructed by using a modified version of MODFLOW 2005, with the surface-water
system represented by using the surface-water routing process (SWR1) and a new...
