Abstract:

Linear construction typically uses drainage conveyances, such as roadside ditches, to convey stormwater runoff away from construction sites to receiving waters. This can expose these receiving waters to polluted runoff if channels are unstabilized giving way to erosive shear stresses in high velocity channelized flow. Therefore, best management practices, such as ditch checks, are used to help reduce channel erosion caused by high velocity flow while propagating sediment deposition within the channel. The Auburn University Erosion and Sediment Control Testing Facility (AU-ESCTF) was used to evaluate and improve various ditch check practices’ performance using large-scale, channelized flow techniques to assist the Alabama Department of Transportation (ALDOT) in better maximizing ditch check performance in the field. One control test and five different types of ditch check practices were evaluated. The five different ditch check practices were: (1) wattles, (2) rip rap, (3) sand bags, (4) silt fence, and (5) stacked wattles. Recommendations on installation modifications for each ditch check practice based upon testing results were made to better enhance the practices’ capabilities.
