MODFLOW-2000 and MODPATH models for simulations used to delineate contributing areas for 2017 pumping conditions to selected wells in Ingham County, Michigan: U.S. Geological Survey data release
A regional groundwater flow model (https://pubs.usgs.gov/sir/2009/5244/) was updated to reflect 2017
pumping conditions in the Tri-County Region covering most of Clinton, Eaton, and Ingham Counties,
Michigan. This model was developed to simulate the regional hydrologic system in Tri-County area
and continues to be used for...
Hyperspectral image data from the Deschutes River near Bend, OR, July 26, 2016
Hyperspectral image data from the Deschutes River near Bend, OR, were acquired on July 26, 2016 to support research on remote sensing of rivers, particularly retrieval of water depth, and to facilitate efforts to characterize habitat for amphibians, primarily the Oregon Spotted Frog. These data were collected by the Compact Airborne Spectrographic Imager (CASI) 1500H manufactured by ITRES...
Datasets from Groundwater-Quality and Select Quality-Control Data from the National Water-Quality Assessment Project, January through December 2015 and Previously Unpublished Data from 2013-2014
Groundwater-quality data were collected from 502 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program and are included in this report. Most of the wells (500) were sampled from January through December 2015 and 2 of them were sampled in 2013. The data were collected from five types of well networks: principal aquifer study...
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...
Data on denitrification and ecological characteristics of nontidal floodplains, Chesapeake Bay watershed, USA, 2013-2016
This data set presents attributes of floodplain ecosystem characteristics including floodplain soil denitrification, floodplain soil biogeochemistry, floodplain vegetation, floodplain sedimentation, floodplain and channel morphometry, stream discharge and water quality, floodplain climate, floodplain physiographic region, and catchment land cover. Attributes are associated with 18 floodplains...
Metabolism estimates for 356 U.S. rivers (2007-2017): 1. Site data
This dataset provides site identifiers, details, and quality indicators. The format is a table with 1 row per site (tab-delimited file). This dataset is part of a larger data release of metabolism model inputs and outputs for 356 streams and rivers across the United States (https://doi.org/10.5066/F70864KX). The complete release includes: modeled...
MODFLOW-2005 and MODPATH6 models used to simulate groundwater flow and transport and base-flow age in two tributaries to the Upper Chester River, Maryland
A steady state three-dimensional groundwater flow (MODFLOW-2005) and advective
transport (MODPATH6) model was developed to examine subsurface travel times to
wells and receiving streams in two subcatchments contributing to the Upper Chester
River, Maryland. The model was calibrated to conditions from 1990 to 2005, the period
for which groundwater levels, stream...
Soil-Water Balance model datasets used to estimate groundwater recharge in Florida and parts of Georgia, Alabama, and South Carolina, 1995-2010
A soil-water balance model (SWB) was developed to estimate recharge to the groundwater flow system in Florida
and parts of Georgia, Alabama, and South Carolina for the period 1995 through 2010. The model was not calibrated;
however, various water budget components from the model output compared reasonably well with other estimates.
The model was used to estimate recharge...
Datasets and metadata for estimates of nitrate loads and yields from groundwater to streams in the Chesapeake Bay watershed based on land use and geology
This USGS data release contains datasets, metadata, and figures associated with estimating nitrate loads and yields from groundwater to streams in the Chesapeake Bay watershed based on land use and geology. There are three shapefiles with associated metadata and figures representing the shapefiles: • Catchments_GWcontribN.shp: NHDPlus catchment estimates of groundwater...
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 investigation...
Dissolved organic carbon and nitrogen release from boreal Holocene permafrost and seasonally frozen soils of Alaska
Permafrost (perennially frozen) and active-layer (seasonally thawed) soils varying in soil carbon (C) and nitrogen (N) content and radiocarbon age were collected from three sites in interior Alaska to determine potential release of dissolved organic carbon (DOC), total dissolved N (TDN), dissolved organic nitrogen (DON), and dissolved inorganic nitrogen (DIN) upon thaw. Soil cores were cut...
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,...
