Standard roadside vegetated swales often do not provide consistent pollutant removal. To increase infiltration and removal, bioswales are designed with an underlying soil media underdrain. However, there little data on the ability of these stormwater control measures (SCMs) to reduce concentrations. A bioswale treating road runoff was monitored, volume-proportional, composite samples taken for inlet, overflow, underdrain outflow. Samples were tested total suspended solids (TSS), volatile...
Bridge deck runoff sometimes directly discharges through drains to water bodies. As such, the is usually not treated; however, recent pressures have led Departments of Transportation install closed pipe drainage systems beneath bridges deliver stormwater a control measure (SCM). This can be costly both in terms up-front and long-term maintenance capital. study compared bridge concentrations nutrients, sediment, heavy metals effluent from six commonly used SCMs. Runoff quality samples 15...
Bioswales are a promising stormwater control measure (SCM) for roadway runoff management, but few studies have assessed performance on field scale. A bioswale is vegetated channel with underlying engineered media and perforated underdrain to promote improved hydrologic water quality treatment. rip-rap lined forebay was constructed along state highway NC 211 in Bolivia, North Carolina, USA, monitored 12 months. Thirty-seven of the 39 rain events exfiltrated into soils, resulting no...
Road runoff has been identified as a source of urban stormwater pollution. Bridges represent special case, they often directly discharge through deck drains near or into open water. As such, the is usually not treated with swale and filter strip, it would be in typical highway cross-section; recently, departments transportation have begun using closed pipe drainage systems to deliver control measure (SCM) for treatment. This costly retrofit both terms up-front long-term maintenance capital....
