MODFLOW-NWT data sets for simulation of Effects of Surface-Water and Groundwater Inflows and Outflows on the Hydrology of the Tsala Apopka Lake Basin in Citrus County, Florida

The U.S. Geological Survey, in cooperation with the Southwest Florida Water Management District,
calibrated a model to quantify the inflows and outflows in the Floral City, Inverness, and Hernando
pools of the Tsala Apopka Lake basin in Citrus County, Florida. The calibrated model, which uses
MODFLOW-NWT version 1.1.2, simulates hydrologic changes in pool stages, groundwater...

Downwelling spectral irradiance profile from the Deschutes River near Bend, OR, July 28, 2016

A vertical profile of downwelling spectral irradiance at different depths within the water column was measured on the Deschutes River near Bend, OR, July 28, 2016, to support research on remote sensing of river discharge. Downwelling spectral irradiance data were collected using an Analytical Spectral Devices FieldSpec3 spectroradiometer operated in irradiance mode and deployed from a...

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...

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...

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...

FTS RSS Temperature Test 1, John C. Stennis Space Center, Nov 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...

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...

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...

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...
