• Abstract:
  Building from large-scale testing involving sediment control technology, the goal of this research project was to perform large-scale evaluations of settling technologies in the sediment basin at Auburn University Erosion and Sediment Control Testing Facility (AU-ESCTF). In particular, the goal was to assess the impacts on the sediment basin performance of: (1) Having a forebay prior to a sediment basin; (2) Changing thickness of coir fiber baffles; (3) Adding high-rate lamella settlers in the sediment basin; and (4) Adding a small-scale high-rate lamella settler to treat skimmer outflow from basins. The assessment of the performance of the basin is mostly based on measurements performed in the sediment basin, which included total suspended solids (TSS), turbidity (with sensors and with handheld turbidimeter), mass of settled soils, and water depth in the basin. Some analyses were also obtained by means of numerical simulation of flows in the sediment basin.
