This dataset contains water-, sediment-, and biological-quality data collected immediately upstream and downstream from 5 bridges in 3 physiographic provinces (Piedmont, Upper Coastal Plain, and Lower Coast Plain) in South Carolina during periods of observable bridge-deck runoff during 2013 to 2018. The associated report (Journey and others, 2020, "Effects of Stormwater Runoff from Selected Bridge Decks on Water-, Sediment-, and Biological-Quality Conditions in Receiving Waters in South Carolina, 2013 to 2018") is available at https://doi.org/10.3133/sir20205046.
Tidal cycle water velocities were measured at transects in the Bushy Park Reservoir using Teledyne Rio Grande 1200 kHz acoustic Doppler current profilers (ADCP). Five transects were measured on August 5, 2014 and November 5, 2014, and two transects were measured on March 26, 2015 and April 23, 2015. The data were collected every 30 minutes over a tidal cycle . The data were georeferenced with differential GPS receivers with submeter accuracy. Data were processed using the "Velocity Mapping Toolbox" (Parsons et al., 2013). Any data assigned a value of "-9999" are bad or missing data and should not be used for analysis. Parsons, D. R., Jackson, P. R., Czuba, J. A., Engel, F. L., Rhoads, B. L., Oberg, K. A., Best,...
Vertical velocities profiles were measured at 15-minute intervals at six locations in the Bushy Park Reservoir using self-contained Sontek Argonaunt XRs upward-facing acoustic Doppler current profilers (ADCPs) with a frequency of either 1,500 or 3,000 kiloHertz (kHz)). The ADCPs were deployed between December 2013 and May 2015. Up to four sites were collected concurrently. Data were processed using ViewArgonaut, a software package developed by SonTek (http://www.sontek.com/softwaredetail.php?ViewArgonaut-Software-21) to compute the average velocity vector (magnitude and direction) for each time step (15-minute) at the location.
