iTOUGH2-EOS7C model used to analyze multiphase flow and underpressured shale at the Bruce Nuclear Site, Ontario, Canada

Hydraulic testing has revealed dramatic underpressures in Paleozoic shales and carbonates at the
Bruce nuclear site in Ontario. Although evidence from both laboratory and field studies suggests that
a small amount of gas phase methane could be present in the shale, previous studies examining
causal linkages between gas phase and the underpressure have been inconclusive. To...

Code, data, executables, and other information used to run Unit Flows in Networks of Channels (UFINCH) - A method for simulating unit and daily flows in networks of channels described by NHDPlus using continuous flow data at U.S. Geological Survey streamg

This U.S. Geological Survey (USGS) data release contains the code, data, executables, and other information necessary to run the application Unit Flows in Networks of Channels (UFINCH). The UFINCH application is a computer code that utilizes the geospatial stream connectivity and catchment geometry described in National Hydrography Dataset Plus value added attributes (NHDPlus Vers

MODFLOW-NWT model data sets used to evaluate changes in the hydrodynamics of Anvil Lake, Wisconsin

A MODFLOW-NWT groundwater flow model was developed to simulate groundwater
movement in the area around Anvil Lake, and groundwater inputs and outputs from
the lake from 1980 to 2014. Surface-water hydrology was simulated using the lake
package. The MODFLOW model was first calibrated for steady-state conditions, or
"average" conditions corresponding to January 1, 1980,...

MODFLOW-2000 model used to illustrate the differences in flow paths and travel times when three-dimensional kriging is used to estimate the hydraulic conductivity distribution as compared to manual determinations of hydraulic conductivity distribution

A three-dimensional (3D) groundwater flow model of the glaciated sediments around Elkhart, Indiana
was constructed as part of the U.S. Geological Survey Groundwater Resources Program using
lithologic records from water well logs. Texture-based hydraulic conductivities were assigned to
vertical intervals along each lithology record. A three-dimensional kriging program read...

MODFLOW-2005 used to evaluate the effects of withdrawals from two aquifers in the New Jersey Coastal Plain for Cumberland County and vicinity, New Jersey

A local and a regional groundwater-flow model were used to evaluate the effects of
withdrawals in Cumberland County and vicinity in New Jersey. The local model
simulated monthly groundwater withdrawals from the unconfined Kirkwood-Cohansey
aquifer system and surface-water diversions from 1997 to 2008. The regional model,
the New Jersey Coastal Plain RASA model,...

Phytoplankton Species Composition, Abundance and Cell Size in San Francisco Bay: Microscopic Analyses of USGS Samples, beginning in 2014

This Data Release makes available measurements of phytoplankton species composition, abundance and cell size made on samples collected in San Francisco Bay (CA) from January 2014 through December 2016. Whole water phytoplankton samples were collected at least monthly at fixed sampling stations along a 145-km transect where the variability of salinity, temperature, turbidity and nutrient...

Downwelling spectral irradiance profile from the Snake River in Grand Teton National Park, WY, August 23, 2015

A vertical profile of downwelling spectral irradiance at different depths within the water column was measured on the Snake River in Grand Teton National Park, WY, August 23, 2015, to support research on remote sensing of rivers. Downwelling spectral irradiance data were collected using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in irradiance mode and deployed fr

Mercury speciation and other constituent data from deep sediment cores in Alviso Slough, South San Francisco Bay, California, 2012-16.

This dataset includes mercury and other constituent concentration and physical properties data for seven deep sediment profiles (ranging from 79 cm to 214 cm in length) collected from the thalwag of Alviso Slough, a major tributary to South San Francisco Bay (California, USA). Field sampling occurred during May 2012 (4 sites) and January 2016 (3 sites). Each profile was compr

FTS RSS Distance Test, John C. Stennis Space Center, Dec 2015

Two identical Radar Stage Sensors from Forest Technology Systems, were evaluated to determine if they are suitable for U.S. Geological Survey (USGS) hydrologic data collection. The sensors were evaluated in laboratory conditions to evaluate the distance accuracy of the sensor over the manufacturer’s specified operating temperatures and distance to water ranges. Laboratory results we

Probability of Streamflow Permanence (PROSPER) Model Output Layers

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 predictions...
