Effects of Sediments on BMPs for Highway Runoff Control

Numerous studies conducted on highway stormwater runoff and its control with Best Management Practices (BMPs) indicate that sediments are the major pollutants that affect performance and longevity of BMPs. Currently, it is essentially unknown: (1) how much sediment will be generated by a construction site or by a section of highway with its surrounding watershed under different conditions–knowledge gap 1; (2) how sediments are intercepted by different BMPs with or without pretreatment sections–knowledge gap 2; and (3) what are the effects of these sediments on BMPs’ hydraulic behavior, longevity, and pollutants removal or release–knowledge gap 3. The objectives of this study are to: (1) develop models to predict both surface runoff and sediment yield from highway systems under different conditions; and (2) evaluate how to incorporate models into design and management of BMPs for highway runoff control. The project will develop models to estimate sediment yield/delivery from different settings (e.g., construction sites, different highway sections) under different environmental (e.g., soils, vegetation, slopes) and weather conditions (e.g., different storm events). The project will identify a few highway sites (e.g., construction sites or highway sections) to collect storm water samples during storm events; we then will quantify sediments to calibrate the model(s). The project will then evaluate how to use the model(s) in BMP design and management. This project will provide important information to fill knowledge gaps 1−3. The project will assist in the planning, design and management of structural BMPs for highway runoff control.
