“…They take advantage of natural processes such as infiltration to reduce the volume and rate of runoff, while at the same time improving water quality [44,45]. The advantages of the infiltration process include groundwater recharge, runoff volume reduction, low stream flow augmentation, and water quality enhancement [46]. In these practices, flood mitigation can be achieved by promoting stormwater infiltration, storage, percolation, and evapotranspiration.…”

One of the best management practices (BMPs) for stormwater quality and quantity control is a bioretention system. The removal efficiency of different pollutants under this system is generally satisfactory, except for nitrogen which is deficient in certain bioretention systems. Nitrogen has a complex biogeochemical cycle, and thus the removal processes of nitrogen are typically slower than other pollutants. This study summarizes recent studies that have focused on nitrogen removal for urban stormwater runoff and discusses the latest advances in bioretention systems. The performance, influencing factors, and design enhancements are comprehensively reviewed in this paper. The review of current literature reveals that a bioretention system shows great promise due to its ability to remove nitrogen from stormwater runoff. Combining nitrification and denitrification zones with the addition of a carbon source and selecting different plant species promote nitrogen removal. Nevertheless, more studies on nitrogen transformations in a bioretention system and the relationships between different design factors need to be undertaken.

“…According to Barrett et al (1998), as long as the road runoff is allowed to flow directly down the side slope into the swale, the side slope acts as a filter strip. Pollutant removal can occur by sedimentation of solid particles onto the soil surface, filtration of solid particles by vegetation, or infiltration and adsorption/degradation of pollutants dissolved in the runoff (Abida and Sabourin, 2006). The infiltration capacity of each swale will depend on many variables and each swale should be examined individually (Ahmed et al, 2015).…”

The side slope to a roadside swale (drainage ditch) constitutes a filter strip that has potential for infiltration of road runoff, thereby serving as a stormwater quantity and quality control mechanism. A total of thirty-two tests were performed during three seasons in four different highways located in the Minneapolis-St. Paul metropolitan area, MN to analyze the infiltration performance of roadside filter strips and the effect of fractional coverage of water on infiltration. Three different application rates were used in the experiments. All the tests showed that water flow on the lateral slope of a roadside swale is concentrated in fingers, instead of sheet flow, at the typical road runoff intensities for which infiltration practices are utilized to improve surface water quality. A linear relationship between flux of water from the road and fraction of wetted surface was observed, for the intensities tested.

“…Alkaline soils and sub-soils promote removal and retention of metals. In addition to infiltration, pollutants can be removed by surface processes including vegetative filtration (mainly particles), sedimentation (of solid particles) and plant uptake (particularly nutrients; some metals) (Abida and Sabourin, 2006;Bäckström, 2002;Schueler, 1987;).…”
