Data

This data release contains results from 2019-2023 for bed material and suspended sediment samples collected at USGS 07374525 Mississippi River at Belle Chasse gage in association with the Louisiana Coastal Protection and Restoration Authority, Lowermost Mississippi River Management Program. Concentration, percent fines and grain size analysis on bed material and suspended sediment...

This data release contains water level observations from a sensor grid deployed in the tidal marshes of the Charles H. Wheeler Wildlife Management Area in the central Long Island Sound (Connecticut, USA). Water level sensors were deployed between August 2018 and December 2018 to serve as a calibration/validation (cal/val) dataset for the development, refinement, and evaluation of remote...

The U.S. Geological Survey is developing national water-use models to support water resources management in the United States. Model benefits include a nationally consistent estimation approach, greater temporal and spatial resolution of estimates, efficient and automated updates of results, and capabilities to forecast water use into the future and assess model uncertainty. In this data...

Since 1975, annual water use for Louisiana has been published on a 5-year basis and is used for a variety of purposes. As the Sparta aquifer is a heavily used aquifer, is the sole source of groundwater for many parishes in Louisiana, and recent withdrawals have exceeded the Sparta’s natural recharge, a more frequent compilation of water usage for the Sparta aquifer in Louisiana is needed...

The Memphis aquifer is the primary source of groundwater for municipal, industrial, and commercial uses in the Memphis area. The Memphis area includes all of Shelby County and parts of Tipton and Fayette Counties in Tennessee, parts of DeSoto and Marshall Counties in Mississippi, and part of Crittenden County in Arkansas (Kingsbury, 2018). Long-term withdrawals form the aquifer since...

This data release contains monthly and annual water-use estimates from the Aquaculture and Irrigation Water-Use Model (AIWUM) version 1.1 for the Mississippi Alluvial Plain (MAP) from 2020 to 2023. Aquaculture and irrigation estimates contained in this data release are representative of groundwater withdrawal for six different categories: aquaculture, cotton, corn, rice, soybeans, and...

This data release contains updated monthly and annual water-use estimates from the Aquaculture and Irrigation Water-Use Model (AIWUM) version 2.0 for the Mississippi Alluvial Plain (MAP) from 2014 to 2023. AIWUM version 2.0 employs remote sensing datasets and machine learning to advance the ability to predict groundwater use in regions with scarce or limited in-situ groundwater...

This dataset contains results of weighted least-squares (WLS) regression for 42 streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) on urban streams in Alabama and Mississippi. WLS regression was used to relate drainage area and the percentages of the drainage basins of the streamgages in developed land use (the sum of classes 21-24 from the 2011...

This item provides Soil-Water-Balance (SWB) model input and output of a water budget simulation for the Mississippi Embayment Regional Aquifer System (MERAS) during the period 2000 to 2024. The output files include gridded daily data (1-kilometer resolution) for net infiltration (potential groundwater recharge), rejected net infiltration, interception, runoff, runoff outside (runoff that...

Results of predicted groundwater levels and related spatial diagnostics, produced by an applied prediction-modeling statistical-research workflow, are provided as multi-banded GeoTIFF rasters for two custom bundles (classifications) of local aquifer codes for many thousands of wells in the hydrogeologically complex Chicot aquifer system, southwestern Louisiana. The modeling workflow was...
