SUTRA model used to evaluate groundwater availability in central Molokai, Hawaii
A three-dimensional, variable-density solute-transport model (SUTRA) was developed
to evaluate the effects of nine selected withdrawal/recharge scenarios on salinity of
groundwater and discharge of freshwater to the nearshore environment of central
Molokaʻi, Hawaiʻi. The model was constructed using water-level and salinity data
available for the period from 1940 to
MODFLOW-NWT groundwater model used for simulating potential future pumping scenarios and forecasting associated groundwater-level changes in the Truxton aquifer on the Hualapai Reservation and adjacent areas, Mohave County, Arizona
A three-dimensional, numerical groundwater flow model of the Hualapai Plateau
and Truxton Basin was developed to assist water-resource managers in
understanding the potential effects of projected groundwater withdrawals on
groundwater levels and storage in the basin. The Truxton Basin Hydrologic
Model (TBHM) was developed using previously published data, as well as, new...

Snake River above Jackson Lake, site number 13010065
Sample and Specific Conductance Monitoring Site Approximately 200 meters downstream from USGS stream gage 13010065 (Latitude N 44°05'56", Longitude W 110°40'03", NAD83). Methods Specific Conductance Data An In-Situ Aqua Troll 100 Data Logger was used to measure and store specific conductance measurements. Specific conductance measurements were made every 15 minutes.
Geophysical data from the unnamed lake at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, MN (ver. 2.0, June 2020)
The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near Bemidji, MN, USA. A high pressure oil pipeline ruptured in 1979 releasing ~1.7 million liters of light crude oil, which sprayed over an area of ~6500 square meters and collected in topographic depressions. Approximately 75% of the spilled oil was recovered. Much of the remainder reached the water t
USGS Measurements of Water Quality in San Francisco Bay (CA), beginning in 2016
The U.S. Geological Survey maintains a program of water-quality studies in San Francisco Bay (CA) that began in 1969. This USGS Data Release archives and makes available all measurements beginning in 2016. Each year, a data file containing the previous year’s data will be added. Water-quality constituent measurements from sensors include salinity, temperature, light attenuation
MODFLOW-2000 and MODPATH4 used to simulate groundwater flow and contaminant transport in the Pohatcong Valley, Warren County, New Jersey
The U. S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency,
developed a numerical ground-water-flow model, using MODFLOW-2000, to simulate
ground-water flow in the Pohatcong Valley including the area within the Pohatcong Valley
Ground Water Contamination Site. In 1978, the chlorinated solvents trichloroethene (TCE)
and tetrachloroethene...

Sample and Specific Conductance Monitoring Site Near the USGS stream gage 06036905 located along the Firehole Canyon (Latitude N 44°37'12.66", Longitude W 110°51'48.61", NAD83). Methods Specific Conductance Data An In-Situ Aqua Troll 100 Data Logger was used to measure and store specific conductance measurements. Specific conductance measurements were made every 15
MODFLOW 6 models used to simulate the long-term average surficial groundwater system for the contiguous United States
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.

MODFLOW-2005 model used to Simulate the Evolution of Fluid Underpressures in the Great Plains, by Incorporation of Tectonic Uplift and Tilting
A sequence of nine two-dimensional cross-sectional groundwater models
using MODFLOW-2005 was created to study whether underpressures
(subhydrostatic heads) in the Paleozoic units underlying the Great Plains
of North America are a consequence of Cenozoic uplift of the area. Based
on tectonostratigraphic data incorporated into these nine models, we have
developed a...
MODFLOW-2005 model used to evaluate water-management scenarios for the Mississippi Delta
A three-dimensional groundwater flow model (MODFLOW-2005) of the Mississippi embayment,
South-Central United States, was developed as part of a national project initiated by the U.S.
Geological Survey Groundwater Resources Program to provide updated assessments of
groundwater availability in important principal aquifers across the United States. The goals
