Data

In 2014, the U.S. Army Corps of Engineers collaborated with the U.S. Geological Survey to develop regional hydraulic geometry curves for the Boston Mountains in Arkansas. To accomplish this, fourteen stream reaches associated with stream flow-gaging stations operated by the U.S. Geological Survey were evaluated. These study reaches had contributing drainage basin areas ranging from 0.19...

The effects of high- and low-flow conditions on biological communities in Alabama streams were investigated by utilizing data on benthic macroinvertebrates, fish communities, hydrology, land use, and water quality. Biological data from streams and rivers in the Mobile River basin and other Gulf Coast drainages was collected from 278 sites between 1999 and 2014. These sites' upstream...

Flood-frequency analyses were conducted for three streamgages operated by the U.S. Geological Survey (USGS) in the Black River basin of southeastern Missouri (MO) and northeastern Arkansas (AR): 07064000, Black River near Corning, AR; 07068000, Current River at Doniphan, MO; and 07069000, Black River at Pocahontas, AR. Results from the analyses will be used for design purposes by the...

This data release contains a dataset of geospatial and tabular data used in support of a flood-frequency study of urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. The dataset includes data used in the development of generalized least-squares (GLS) regression equations for predicting streamflows at ungaged locations in the study...

Four indices—the Langelier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius Scaling Index (PSI), and the Potential to Promote Galvanic Corrosion (PPGC) — in addition to an analysis which normalized the results from the existing indices, the Combined Index (CI), were used to assess the potential corrosivity of groundwater in Louisiana. The text file 'potential corrosivity...

This dataset consists of sensor profile and water sample results from monitoring campaign to investigate the effects of two dredged pits in eastern Lake Pontchartrain on dissolved oxygen conditions within the water column in and surrounding the pits over a three-year period. The borrow pits were excavated to provide soil material to nourish three nearby protected marsh sites: Bayou...

This dataset contains results of generalized least-squares (GLS) regression for 136 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Tennessee and parts of Alabama, Georgia, Mississippi, North Carolina, and South Carolina. GLS regression was used to relate drainage area, percentages of the drainage basins of the streamgages in...

Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater systems in karst systems. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of...

This data release contains reflectance spectra of residue (senesced vegetation) for common row crops (corn, soybean, winter wheat) as well as diverse cover crops (cereals, legumes, brassicas) collected in the laboratory using Analytical Spectral Devices (ASD) spectrophotometers (n = 296) and collected in the field using the Itialian Space Agency's spaceborne PRecursore IperSpettrale...

Highly altered agricultural watersheds like the Mississippi Alluvial Plain (MAP) in Mississippi, USA pose significant challenges for developing biological stressor-response relationships to monitor ecological improvements from best management practices (BMPs). Previous research (Taylor et al., 2023) has indicated that MAP streams have elevated nutrient and ion concentrations as well as...

Global demand for lithium, the primary component of lithium-ion batteries, greatly exceeds known supplies and this imbalance is expected to increase as the world transitions away from fossil fuel energy sources. The goal of this work was to calculate the total lithium mass in brines of the Reynolds oolite unit of the Smackover Formation in southern Arkansas using predicted lithium...

Groundwater is heavily used for public supply and industrial uses in the Baton Rouge area. Lowered water levels resulting from groundwater withdrawals have induced the movement of saltwater towards wells in East Baton Rouge and West Baton Rouge Parishes. Saltwater intrusion has the potential to affect water supply infrastructure, reduce water availability for certain uses, and increase...
