The Alabama Department of Transportation (ALDOT) and the U.S. Geological Survey (USGS) studied several sites in the northern East Gulf Coastal Plain of Alabama to investigate effects of newly installed box culverts on the natural conditions of the streams they are traversing (Pugh and Gill, 2021). Data collection for the study spanned approximately 10 years and included before-, during-, and after-construction phases of box culvert installations at selected stream sites. The objectives of the project were to (1) assess the degree and extent of changes in geomorphic conditions, suspended-sediment concentrations, turbidity, and benthic macroinvertebrate populations at selected small streams following box culvert installation...

This dataset consists of a map depicting the distribution of cedar along the Natchez Trace Parkway. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center. In the final version of "Mapping the Natchez Trace Parkway," the Cedar class was merged with the Pine class (the alliance most frequently mistaken for cedar).
This dataset consists of a map depicting aquatic vegetation along the Natchez Trace Parkway. Four herbaceous aquatic alliances were manually mapped and aggregated as an aquatic vegetation class. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.

This spreadsheet features the center points of 388 aerial photography frames taken of the Natchez Trace Parkway. The color infrared photography was flown in late September and early October of 2004 during leaf-on conditions as required by National Park Service (NPS) personnel to accomplish their ground-based landcover classification.
To improve flood-frequency estimates at rural streams in Alabama, annual exceedance probability (AEP) flows at gaged streams in Alabama and regional-regression equations, used to estimate AEP flows for ungaged streams in Alabama, were developed using current geospatial data, additional statistical methods, and annual peak-flow data through the 2015 water year. The regional-regression equations were derived from statistical analyses of peak-flow data, basin characteristics associated with 217 streamgages, and the generalized skew from Bulletin 17B (Interagency Advisory Committee on Water Data, 1982). Four flood regions were identified based on residuals from the regional-regression analyses. Regional regression...
This dataset represents the center points of 379 aerial photography frames taken of the Natchez Trace Parkway. The color infrared photography was flown in late September and early October of 2004 during leaf-on conditions as required by National Park Service (NPS) personnel to accomplish their ground-based landcover classification.
The northern Gulf of Mexico coast spans two major climate gradients and represents an excellent natural laboratory for developing climate-influenced ecological models. In this project, we used these zones of remarkable transition to develop macroclimate-based models for quantifying the regional responses of coastal wetland ecosystems to climate variation. In addition to providing important fish and wildlife habitat and supporting coastal food webs, these coastal wetlands provide many ecosystem goods and services including clean water, stable coastlines, food, recreational opportunities, and stored carbon. Our objective was to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure...

Potential evapotranspiration (PET), and reference evapotranspiration (ETo) are estimated at a 1-kilometer spatial resolution and daily time-scale from January 1, 2022 to December 31, 2022 for Florida, Alabama, Georgia, South Carolina, and parts of Mississippi, North Carolina, and Tennessee. PET and ETo were computed on the basis of solar radiation, meteorological data (min/max temperature, min/max relative humidity, and mean wind speed at 2-meter height), and shortwave blue-sky albedo data. Solar radiation was computed from Geostationary Operational Environmental Satellite (GOES) sensor data, blue-sky albedo was computed from the Moderate Resolution Imaging Spectrometer (MODIS) MCD43A1 BRDF/Albedo data product,...
This dataset represents aerial photography of the Natchez Trace Parkway that was taken in late September and early October of 2004. Images were acquired during leaf-on conditions as required by the National Park Service (NPS) to accomplish their ground-based vegetation classification. Nearly 400 aerial photography frames were scanned and orthorectified to generate digital orthophoto quarter quads (DOQQs). These were cut to match existing DOQQs creating a total of 235 DOQQs for the entire 715 km long Parkway. For ease of use, the DOQQs were grouped into 11 mosaics, each covering a section of the Parkway. At the request of the NPS, each mosaic was divided into ten tiles to allow for efficient loading on less robust...
This dataset consists of linear features depicting the main road running through the Natchez Trace Parkway and other roads visible on the color infrared photography. The Parkway is a 715-km roadway that historically connected the southern portions of the Mississippi River to the salt licks in central Tennessee. The vector data represent the roadway of the Parkway at an approximate along-track (parallel and perpendicular to the road) with a spatial accuracy of about 3 meters or less.
This dataset consists of a map depicting the distribution of sweetgum-oak mixed forests along the Natchez Trace Parkway. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center. In the final version of "Mapping the Natchez Trace Parkway," the Sweetgum-Oak class was merged with the Sweetgum class because most of the time it co-occurred with the Sweetgum field sites.
This dataset defines the symbology for the landcover map of the Natchez Trace Parkway. The map shows the distribution of 18 landcover classes based on the National Vegetation Classification Standard. Ground-based vegetation classification was provided by National Park Service (NPS). The mapping output and layer delineate grasses, road-developed areas, scrub-shrub, shrubland, plantation, water bodies, areas of white oak, oak, pine-oak, pine-cedar, pine-sweetgum, sweetgum (including sweetgum-oak), scattered trees, swamp forest, irregular classes, aquatic vegetation, invasive species, canopy gaps, and clouds. Mapped classes that have been digitized are noted with an asterisk (*) in the legend.

This dataset consists of a map depicting suspected sites of invasive species along the Natchez Trace Parkway. Four invasive species were manually mapped and aggregated as an invasive species class. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.
This dataset consists of a map depicting the distribution of irregular classes along the Natchez Trace Parkway. Irregular classes are those forest alliances that were usually represented by one or two field sites. In addition, these alliances did not align with any of the major forest classes and for the most part did not contain species that were common to other alliances. Ground-based vegetation classification was provided by the National Park Service and mapped by the U.S. Geological Survey, National Wetlands Research Center.
