This dataset belongs to the paper titled 'Contaminant removal efficiency of floating treatment wetland' published by Environmental Research Letters.
The abstract of the paper is: Floating treatment wetlands are new ecological infrastructures for stormwater treatment. Despite a recent proliferation in their usage their contaminant removal efficiency e continues to draw research attention. Here the e from idealized FTWs is numerically computed across a wide range of flow and geometric conditions while accommodating joint contributions of advection turbulent dispersion and vegetation removal. The emerging mathematical structure describing e bears resemblance to a simplified plug flow model and supports an empirical shallow-basin models from long-term field measurements. The present model indicates that e remains significantly influenced by a Dämkohler number that quantifies the effects of both vegetation and flow properties. The impacts one of the underflow region and contaminant blockage on the removal mechanisms are also investigated.
