“…Such impoundments reduce erosive forces and shear stress along the channel surface and promote sedimentation. DCs are commonly assembled from various materials, including SF, wattles, riprap, sandbags, hay bales, and other proprietary products ( 20 ). AU-SRF designed and installed a testing apparatus to evaluate channelized flow E&SC practices.…”

Sediment remains one of the most commonly occurring pollutants affecting the U.S.’s water bodies, as identified by the United States Environmental Protection Agency (USEPA) ( 1). Construction activities largely accelerate soil erosion and subsequent sediment deposition. The National Pollutant Discharge Elimination System Construction General Permit requires construction operators to implement erosion and sediment control (E&SC) plans to minimize downstream implications from sediment-laden discharge. However, E&SC practices are often designed from “rules of thumb” and lack scientific, performance-based evidence in their design and implementation. The Auburn University Stormwater Research Facility (AU-SRF), previously the Auburn University Erosion and Sediment Control Testing Facility (AU-ESCTF), is an outdoor research center dedicated to evaluating E&SC practices and products commonly used on highway construction projects. Large-scale test apparatuses and methods at AU-SRF are designed to mimic construction site conditions, including rainfall, flow rates, topography, and soil characteristics, to evaluate existing and novel E&SC practices. Since its inception in 2008, AU-SRF has provided small-, medium-, and large-scale testing evaluations for numerous Departments of Transportation and product manufacturers. Findings from controlled testing have continued to inform the selection, design, implementation, and maintenance of E&SC practices used on construction sites and protect downstream waters and infrastructure. In the first decade, AU-SRF has directed 13 research projects and produced more than 30 peer-reviewed publications and 100 professional presentations. As AU-SRF grows into its second decade and efforts reach outside of the southeastern region, the mission to advance knowledge through E&SC research and development, product evaluation, and training remains constant. This review synthesizes the research produced from large-scale testing at AU-SRF to date and presents ongoing projects.

Sediment barriers (SBs) are stormwater management devices often installed along the perimeter of a construction site to intercept and treat overland sediment-laden flow before discharge into the surrounding environment. Effective SB practices remove stormwater pollutants by creating a temporary impoundment upstream of the practice which facilitates sediment capture via sedimentation. Controlling agencies and design practitioners often specify the installation of two SB practices (i.e., primary and secondary SB) in areas where enhanced stormwater treatment is critical because of downstream environmental concerns (e.g., impaired waters). This study sought to identify the overall performance of a commonly specified double-row SB (i.e., double-row silt fence), as well as six alternative designs that utilized various secondary SB practices that could be easily paired with a primary silt fence SB. Small-scale experiments were conducted on each of these double-row design configurations to develop a comprehensive understanding of their performance capabilities. A statistical analysis conducted on 700 water quality data points suggests that all six alternative double-row designs significantly outperformed the double-row silt fence installation. Water quality improvements achieved using alternative secondary SBs ranged from 11% to 71% during the 30 min test period and 14% to 60% during the 90 min dewatering period. In comparison, the double-row silt fence installation only achieved 5% and 1%, respectively. Additionally, post-test observations of secondary SB cross sections indicate that, at best, only half of the matrix filter media within the secondary SB contacts sediment-laden flow. This observation suggests that alternative cross-sectional designs could improve media utilization.
