Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah Model of groundwater flow, gas migration, and reactive transport in the Virgin River Basin, SW Utah
To better understand the possible risks posed to shallow groundwater resources by geologic carbon sequestration (GCS), a multi-scale numerical modeling approach was invoked using the TOUGHREACT code from Lawrence Berkeley National Laboratory. The code solves coupled equations representing conservation of mass and energy on a finite difference grid to simulate multiphase, multicomponent...
Temperature, relative humidity and cloud immersion data for Luquillo Mountains, eastern Puerto Rico, 2014-2019 Temperature, relative humidity and cloud immersion data for Luquillo Mountains, eastern Puerto Rico, 2014-2019
Supplementary data for studies conducted in the Luquillo Experimental Forest (LEF), eastern Puerto Rico include measurements of temperature, relative humidity and cloud immersion at 30-minute resolution. Temperature and relative humidity were measured at five sites; two primary sites have records from March 2014 to June 2019; other sites have shorter records within that period. From...
Basin Characteristic Layers for the Upper Colorado & Gunnison Rivers Pilot Project for StreamStats 2020 Basin Characteristic Layers for the Upper Colorado & Gunnison Rivers Pilot Project for StreamStats 2020
The U.S. Geological Survey (USGS) calculated multiple basin characteristics as part of preparing the Upper Colorado & Gunnison Rivers Pilot StreamStats application. These datasets are raster representations of various environmental, geological, and land use attributes within the Upper Colorado & Gunnison Rivers study area (also known as the Next-Generation Water Observing System, or...
SEAWAT code used to couple MODFLOW and MT3DMS models, and supplemental data used to simulate groundwater flow and tritium transport from the HANDLEY underground nuclear test, Pahute Mesa, southern Nevada SEAWAT code used to couple MODFLOW and MT3DMS models, and supplemental data used to simulate groundwater flow and tritium transport from the HANDLEY underground nuclear test, Pahute Mesa, southern Nevada
Three-dimensional numerical models were used to determine the permeable pathways between the HANDLEY underground nuclear test and downgradient boreholes ER-20-12 and PM-3, Pahute Mesa, southern Nevada. The SEAWAT code was used to couple MODFLOW and MT3DMS models, where the coupled model simulated groundwater-flow and tritium migration from the HANDLEY test for 50 years, from the date of...
Long-term annual aeolian dust deposition data from seven locations in southeastern Utah Long-term annual aeolian dust deposition data from seven locations in southeastern Utah
These data are annual aeolian dust deposition calculations from vertical deposition at seven locations near the vicinity of Moab, Utah covering the period from 1999 to 2020. Data were collected by the U.S. Geological Survey Geosciences and Environmental Change Science Center (Denver, Colorado) and Southwest Biological Science Center (Moab, Utah) to "monitor sediment characteristics at...
Data to Incorporate Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin Data to Incorporate Water Quality Analysis into Navigation Assessments as Demonstrated in the Mississippi River Basin
This data release includes estimates of annual and monthly mean concentrations and fluxes for nitrate plus nitrite, orthophosphate and suspended sediment for nine sites in the Mississippi River Basin (MRB) produced using the Weighted Regressions on Time, Discharge, and Season (WRTDS) model (Hirsch and De Cicco, 2015). It also includes a model archive (R scripts and readMe file) used to...
