AFIs have been documented as an efficient, environment-friendly, and cost-effective method to tackle nutrient pollution. However, although the number of AFI studies has steadily increased over the past two decades, a majority of them were conducted in controlled conditions with short monitor duration while our predictive ability of AFI performance under natural environments, having seasonal-variable physical, chemical, and biological conditions, is still limited.In the present study, we reviewed the evolution and performance of AFI applications for water quality improvement over the past two decades, identified the gaps in current studies relating to field-scale applications of AFIs, and conducted a combination of field and mesocosm experiments to assess the nutrient removal efficiency of AFIs containing two native aquatic plant species, <i>Carex comosa</i> and <i>Eleocharis palustris</i>. Results from our field/mesocosm experiments showed that both species experienced a significant decline in biomass accumulation and plant elongation metrics in late summer, suggesting that seasonality strongly influenced the growth conditions of macrophyte, hence affecting the nutrient removal performance of AFIs. <i>Carex comosa</i> significantly outperformed <i>Eleocharis palustris</i> on biomass accumulation, with average increase in dry biomass of 33.2 ± 18.8 g/plant for shoots and 25.3 ± 11.9 g/plant for roots. This suggests that <i>Carex comosa</i> is a promising candidate for AFI applications aiming at removing nutrients from urban runoff effluents. 2021-10-07 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1619148162009876 http://rave.ohiolink.edu/etdc/view?acc_num=osu1619148162009876 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
