MODFLOW-2005 data sets for simulation of Groundwater-Flow Budget for the Lower Apalachicola-Chattahoochee-Flint River Basin in Southwestern Georgia and Parts of Florida and Alabama, 2008-12

As part of the National Water Census program in the Apalachicola-Chattahoochee-Flint (ACF)
River Basin, the U.S. Geological Survey evaluated the groundwater budget of the lower ACF,
with particular emphasis on recharge, characterizing the spatial and temporal relation between
surface water and groundwater, and groundwater pumping. To evaluate the hydrologic budget of

Watershed Boundaries for the U.S. Geological Survey Southeast Stream Quality Assessment

In 2015, the second of several Regional Stream Quality Assessments (RSQA) was done in the southeastern United States. The Southeast Stream Quality Assessment (SESQA) was a study by the U.S. Geological Survey (USGS) National Water Quality Assessment (NAWQA) project. One of the objectives of the RSQA, and thus the SESQA, is to characterize the relationships between water-quali

Recovery data for surface water, groundwater and lab reagent samples analyzed by the USGS National Water Quality Laboratory schedule 2437, water years 2013-15.

Analytical recovery is the concentration of an analyte measured in a water-quality sample expressed as a percentage of the known concentration added to the sample (Mueller and others, 2015). Analytical recovery (hereafter referred to as “recovery”) can be used to understand method bias and variability and to assess the temporal changes in a method over time (Martin and

Biogeochemical analyses of water samples collected in the mudstone aquifer underlying the Naval Air Warfare Center, West Trenton, NJ (2008-2013)

These data sets present results from the analyses of groundwater samples collected from monitoring wells and monitoring intervals in bedrock wells in the mudstone aquifer underlying the former Naval Air Warfare Center (NAWC), West Trenton, NJ. The water samples were collected between 2008 and 2013 and were analyzed for field parameters, inorganic and organic constituents, and the abun

Daily streamflow datasets used to analyze trends in streamflow at sites also analyzed for trends in water quality and ecological condition in the Nation's rivers and streams (output)

In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitor

MODFLOW-2005 and PEST models used to simulate multiple-well aquifer tests and characterize hydraulic properties of volcanic rocks in Pahute Mesa, Nevada

A three-dimensional, groundwater-flow model (MODFLOW-2005) was developed to estimate the hydraulic
properties (e.g., transmissivity, hydraulic conductivity, specific yield, and specific storage) of volcanic rocks
in Pahute Mesa, Nye County, Nevada. The model was calibrated using parameter estimation (PEST) by
fitting estimated drawdowns to simulated drawdowns fr

Yukon River Basin, Active Layer Network: Active Layer Depth Measurements

This dataset includes active layer depth measurements made annually at Active Layer Networks across the Yukon River Basin in Alaska and Canada. Active layer depth measurements are made using a calibrated metal rod pushed into the soil until permafrost is reached. Each network location consists of a 45 meter by 45 meter grid, measurements are made annually at the time of maximum active layer...

Yellowstone River at Yellowstone Lake Outlet (YYFB)

Yellowstone River at Yellowstone Lake Outlet (YYFB), Yellowstone National Park Sample Collection: Samples were collected near the USGS stream gage 06186500 (Latitude 44°34'01.53", Longitude 110°22'49.46" NAD83). At the time of collection, all waters samples were filtered through a syringe filter (0.45-micrometer). Two splits of the filtered water were r
