SEAWAT Model of Flow and Chloride Transport in the 1,500-Foot, 2,400-Foot, and 2,800-Foot Sands of the Baton Rouge Area, Louisiana

An updated three-dimensional, groundwater-flow and chloride-transport model (SEAWAT) 
of the Southern Hills regional aquifer system in southeastern Louisiana and southwestern 
Mississippi was developed to examine the effects of groundwater withdrawals on the rate 
and pathways of saltwater migration in the “1,500-foot” sand, “2,400-foot” sand, and 
“2,800-foot” sand.  New interpretations of stratigraphic correlations amongst geophysical 
well logs were utilized to revise a hydrogeologic-framework that delineates the depth and 
thickness variations of aquifers and confining units in the Southern Hills regional aquifer 
system. Regional groundwater flow throughout the Southern Hills regional aquifer system 
was first simulated with MODFLOW, and flow-model parameters were calibrated to 8,810 
water levels observed through 2016 with the parameter-estimation code PEST++. Saltwater 
transport was subsequently simulated for the “1,500-foot” sand, “2,400-foot” sand, and 
“2,800-foot” sand with the variable-density code, SEAWAT. Chloride-concentration 
measurements were used as a proxy for the saltwater to formulate the concentration 
initial conditions and calibrate the transport-model parameters. Three hypothetical 
groundwater management scenarios are included in the archive. These scenarios 
simulate the future water levels and chloride concentrations within the “1,500-foot” 
sand, “2,400-foot” sand, and “2,800-foot” sand if groundwater withdrawals were to 
continue at 2016 rates or if one of two proposed modifications to the 2016 withdrawals 
from the “1,500-foot” sand or “2,800-foot” sand were to be enacted. The model was 
calibrated to water levels measured in aquifers beneath the “400-foot” sand, and water 
levels simulated in these aquifers could be used for various purposes, including predicting 
the effects of changing pumping rates. Water planners and managers need additional 
knowledge about the effects of groundwater withdrawals on the rate and pathways of 
saltwater migration and a tool to assess possible management strategies that could 
control further saltwater encroachment in the Baton Rouge area. This USGS data release 
contains all of the input and output files for the simulations described in the associated 
model documentation report (https://doi.org/10.3133/sir20195102).

Processed Continuous Resistivity Profile Data Collected in the Potomac River/Chesapeake Bay on Sept. 6, 2006

In order to test hypotheses about groundwater flow under and into Chesapeake Bay, geophysical surveys were conducted by U.S. Geological Survey (USGS) scientists on Chesapeake Bay and the Potomac River Estuary in September 2006. Chesapeake Bay resource managers are concerned about nutrients that are entering the estuary via submarine groundwater discharge, which are contributing to eutrophication.  The USGS has performed many related studies in recent years to provide managers with information necessary to make informed decisions about this issue.  The research carried out as part of the study described here was designed to help refine nutrient budgets for Chesapeake Bay by characterizing submarine groundwater flow and discharge of groundwater beneath part of the mainstem and a major tributary, the Potomac River Estuary.

Digital Shoreline Analysis System version 4.3 transects and short-term (1970-2009) linear regression shoreline change statistics within the Nantucket coastal region including the Nantucket Sound-  and Atlantic Ocean- facing coasts of Nantucket, Muskeget and Tuckernuck Islands (Nantucket_transects_rates_STlr.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).

Boundary of the Death Valley region by Bedinger and others (1989), for the Death Valley regional ground-water flow system study, Nevada and California

This digital data set delineates the boundary of the Death Valley region that was first evaluated by the 
U.S. Geological Survey (USGS) as a potential hydrogeologic environment for isolation of high-level 
radioactive waste in 1981. Identifying potential high-level waste isolation regions within the Basin and 
Range physiographic province continued through the 1980's and resulted in comprehensive geologic 
and hydrologic characterization of select areas. As part of these studies, Bedinger and others (1989) 
evaluated the Death Valley region, an area of about 80,200-square kilometers in southern Nevada and 
California, with respect to the geology at repository target depths, ground-water flow, potential transport 
of radionuclide material, mineral and energy resources, geomorphic processes, tectonic hazards, and 
the effects of climatic and geomorphic change on the ground-water system. The study by Bedinger and 
others (1989) served as one of the historical references used to support development of the transient 
ground-water model of the Death Valley regional ground-water flow system (DVRFS) completed in 2004 
by the USGS (see "Larger Work Citation").

Shapefile of the Single-beam Bathymetry Tracklines Surveyed in May-June, 2015 from Grand Bay Alabama/Mississippi

As part of the Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES), scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center conducted a single-beam bathymetry survey within the estuarine, open bay and tidal creek environments of Grand Bay Alabama/Mississippi, in May-June 2015. The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetlands and estuarine environments along the northern Gulf of Mexico, specifically Grand Bay AL/MS and Vermilion Bay, Louisiana, as well as along the US east coast in Chincoteague Bay Virginia/Maryland. The data included in this data release will provide baseline bathymetric information for future research investigating wetland/marsh evolution, sediment transport, recent and long term geomorphic change, and will support modeling of future changes in response to restoration and storm impacts.  The survey area encompasses more than 40 square kilometers (km2) of Grand Bay’s incorporated waters.  This data release archives processed single-beam bathymetry data, collected from May 28-June 3, 2015 (USGS Field Activity Number [FAN] 2015-315-FA). Geographic information system (GIS) data products include: a 10 and 30-meter cell size interpolated bathymetry grid, trackline maps, and point data files. Additional files include error analysis maps, Field Activity Collection System (FACS) logs, and formal Federal Geographic Data Committee (FGDC) metadata.

Ocean wave time-series data along the Alaska coast simulated with a global-scale numerical wave model under the influence of CMIP6 wind and sea ice fields

This dataset presents projected hourly time-series of wave heights, wave periods, incident wave directions and directional spreading at distinct points along the open coast of Alaska for the years 2020 through 2050. The projections were developed by running the National Oceanic and Atmospheric Administration’s (NOAA’s) WAVEWATCHIII model. Wind and sea ice fields from seven different Global Climate or General Circulation Models from the CMIP6 High-Resolution Model Intercomparison Project were used to simulate waves across the globe at a 0.5-degree resolution (approximately 50 kms, depending on latitude) and further downscaled to 10- (approximately 18 kilometer) and 4-arc-minute (approximately 7 kilometer) model grids. Point model output data extracted from NOAA’s 4-arc-minute grid for Alaska (ak_4m) are provided herein.

GFLOW model used to characterize the groundwater resources of the Medford Unit of the Chequamegon-Nicolet National Forest, Wisconsin

The model simulates two-dimensional groundwater flow and base flow in streams in 
the Medford Unit of the Chequamegon-Nicolet National Forest using the analytic 
element program GFLOW (Haitjema, 1995). Significant streams and lakes in the 
model domain are represented at varying levels of detail as linesink elements fully 
connected to the groundwater system. The highest level of detail is given to surface 
water features within the Forest Unit, while greatly simplified features around the 
perimeter of the model provide a boundary condition for the groundwater flow system. 
Groundwater discharge to the linesinks is computed, and routed through the surface 
water network as base flow. Recharge to the groundwater system was obtained from 
a separate soil-water-balance (SWB) model, which uses topography, soils, land use, 
and climatic data to estimate recharge as deep drainage from the soil zone. Estimated 
average annual recharge rates were supplied to the GFLOW model on a regular 1-km 
grid covering the model domain, using the Hybrid GFLOW-MODFLOW feature of GFLOW.
		
The model was calibrated to groundwater levels, interpreted lake stages, and estimated 
annual base flows in streams, \with an emphasis on data collected since 1970. Parameters 
representing hydraulic conductivity, groundwater recharge, and surface water bed-sediment 
resistance were adjusted using the parameter estimation program PEST, to produce 
simulated groundwater levels and base flow estimates that agree with field measurements, 
and input parameter values that are consistent with previous studies and the conceptual 
understanding of the area. This USGS data release contains all of the input and output for 
the simulations described in the published report, which can be found in the main directory 
of this data release.
