Soil survey maps were examined to better understand the surficial materials at each study site. Soil maps provide information about soil properties and their behavioral characteristics. Soil survey maps were generated using the United States Department of Agriculture-Natural Resources Conservation Service’s (USDA-NRCS) Web Soil Survey (WSS) tool (http://websoilsurvey.sc.egov.usda.gov/). The USDA-NRCS WSS maps are presented as separate Portable Document Format (PDF) files. References Soil Survey Staff, Natural Resources Conservation Service, United States Department of Agriculture.

Benthic macroinvertebrate samples to evaluate before- and after-culvert construction phases were collected at seven study sites. Samples were collected in two reaches at each site, one upstream and one downstream of the culvert installation. Biological data for all seven sites (14 sample reaches) are included in this data release. In the summer of 2011, samples were collected from upstream and downstream reaches at six stream sites. Samples from Oakmulgee Creek, Northington Branch, Lye Branch, Mill Creek, and Kanetuche Creek represented conditions before culvert construction. The samples from the Tributary to Cahaba River represented conditions during construction since the culvert was already constructed and active...

As part of a cooperative study by the Alabama Department of Transportation (ALDOT) and the U.S. Geological Survey, topographic surveys of stream channel cross-sections, upstream and downstream of selected new culvert installations in the East Gulf Coastal Plain of Alabama, were conducted both before and after culvert construction. This dataset contains raw topographic data used to determine channel measurements for statistical analysis in the associated Scientific Investigations Report, Effects of culvert construction on streams and macroinvertebrate communities at selected sites in the East Gulf Coastal Plain of Alabama, 2010-19 (Pugh and Gill, 2021). To measure the effects that culvert construction may have on...

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...
