FLASH-R (Flow-Log Analysis of Single Holes) FLASH-R (Flow-Log Analysis of Single Holes)
FLASH-R (Flow-Log Analysis of Single Holes) is an R app for the analysis of borehole vertical flow logs to estimate fracture (or layer) transmissivities and far-field hydraulic heads. This app is a new version of the FLASH spreadsheet tool by Day-Lewis et al. (2011) . The program is written in R, an open-source environment. All previous features have been retained and new features...
Hydrogeochemical data for the characterization of stream, groundwater, and beaver-induced floodplain exchange in the East River Science Focus Area, Crested Butte, CO Hydrogeochemical data for the characterization of stream, groundwater, and beaver-induced floodplain exchange in the East River Science Focus Area, Crested Butte, CO
The U.S. Geological Survey, along with scientists from Rutgers University, collected water chemistry, electromagnetic, redox-potential, dissolved oxygen, water flow rate, and water temperature data along stream and river corridors in multiple sub-watersheds of the East River Science Focus Area (SFA) near Crested Butte, CO. The concept of 'river corridor' science recognizes that the...
Geophysical data from the unnamed lake at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, MN (ver. 3.0, May 2022) Geophysical data from the unnamed lake at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, MN (ver. 3.0, May 2022)
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...
Electrical geophysical data collected in the shallow sediments of Snake Pond, Cape Cod, USA Electrical geophysical data collected in the shallow sediments of Snake Pond, Cape Cod, USA
Quantification of mobile/less-mobile porosity dynamics at the sediment/water interface is critical to predicting contaminant storage, release, and transformation processes. Zones in groundwater flow-through lakes where lake water recharges the aquifer can strongly control aquifer water quality. Less-mobile porosity has previously been characterized in aquifers using flow path scale (10's...
Temperature and seepage data from a lake-bottom permeable reactive barrier, Ashumet Pond, Falmouth, MA, 2004-2015. Temperature and seepage data from a lake-bottom permeable reactive barrier, Ashumet Pond, Falmouth, MA, 2004-2015.
These data were collected to evaluate groundwater/surface-water exchange in the area of a lake-bottom permeable reactive barrier and to assess changes in groundwater seepage over the period between 2004 and 2015. This data release includes geospatial datasets, comma separated values (.csv) files, and associated FGDC-compliant metadata representing data collected between 2004 and 2015 as...

GW/SW-MST: A groundwater/surface-water method selection tool GW/SW-MST: A groundwater/surface-water method selection tool
Groundwater/surface-water (GW/SW) exchange and hyporheic processes are topics receiving increasing attention from the hydrologic community. Hydraulic, chemical, temperature, geophysical, and remote sensing methods are used to achieve various goals (e.g., inference of GW/SW exchange, mapping of bed materials, etc.), but the application of these methods is constrained by site conditions...

Geostatistical mapping of salinity conditioned on borehole logs, Montebello Oil Field, California Geostatistical mapping of salinity conditioned on borehole logs, Montebello Oil Field, California
We present a geostatistics-based stochastic salinity estimation framework for the Montebello Oil Field that capitalizes on available total dissolved solids (TDS) data from groundwater samples as well as electrical resistivity (ER) data from borehole logging. Data from TDS samples (n = 4924) was coded into an indicator framework based on falling below four selected thresholds (500, 1000...

Estimating and forecasting time-varying groundwater recharge in fractured rock: A state-space formulation with preferential and diffuse flow to the water table Estimating and forecasting time-varying groundwater recharge in fractured rock: A state-space formulation with preferential and diffuse flow to the water table
Rapid infiltration following precipitation may result in groundwater contamination from surface contaminants or pathogens. In fractured rock, contaminants can migrate rapidly to points of groundwater withdrawals. In contrast to the temporal availability of groundwater quality chemical indicators, meteorological and groundwater level observations are available in real-time to estimate...

Exploring environmental factors that drive diel variations in tree water storage using wavelet analysis Exploring environmental factors that drive diel variations in tree water storage using wavelet analysis
Internal water storage within trees can be a critical reservoir that helps trees overcome both short- and long-duration environmental stresses. We monitored changes in internal tree water storage in a ponderosa pine on daily and seasonal scales using moisture probes, a dendrometer, and time-lapse electrical resistivity imaging (ERI). These data were used to investigate how patterns of in...

Nuclear magnetic resonanance logs of fractured bedrock at the Hidden Lane Landfill site, Culpeper Basin, Virginia Nuclear magnetic resonanance logs of fractured bedrock at the Hidden Lane Landfill site, Culpeper Basin, Virginia
In May 2018, the U.S. Geological Survey (USGS) in cooperation with the U.S. Environmental Protection Agency (EPA) collected borehole nuclear magnetic resonance (bNMR) logs in three boreholes completed in sandstone and siltstone of the Balls Bluff Member of the Bull Run Formation at a Superfund Site in Culpeper Basin, Virginia. The bNMR logs were used to aid in the evaluation of the...
