Abstract:

Conveyance channels are commonly used on highway construction projects to manage the flow of water through the project to downstream discharge points or stormwater detention practices. However, these channels can be at risk of erosion before stabilization due to high-velocity flows. A common erosion control practice in channels is a rock check dam, which aims to slow flow by forming impoundment upstream of installations. Based on common spacing guidance, if rock check dams do not impound to their full height, areas of the channel will still be subject to erosive flow conditions. Past research has indicated that a geotextile overlay or smaller choker stone is required to facilitate a full impoundment, particularly in low flow conditions. Despite the widespread use of rock check dams, very few standards include overlays or chokers or have been evaluated for performance. To evaluate the Iowa Department of Transportation (DOT) standard rock check dam installation and develop more efficient and cost-effective modified installations, a standard Iowa DOT channel located at the Auburn University – Stormwater Research Facility was used.
