Performance of Rolled Erosion Control Products (RECPs) as Bioswale Revetments

Vegetated swales, or bioswales, are among the most commonly used type of green infrastructure (GI) for managing stormwater in temperate climate regions. However, performance data on bioswale drainage technology applied to highly weathered soils (low fertility, high acidity, and erosion prone) tropical subtropical climates still limited. Aimed at closing this gap, research investigated performance—assessed terms vegetation biomass, biodiversity coverage swale, structural integrity revetments, control potential—and cost effectiveness five rolled products (RECPs) currently available market, combination with herbaceous as revetment soils. Additionally, project evaluated a new preseeded RECP, Preseeded Reinforcement Mat, areas that difficult access. The performances all six RECPs were generally adequate revetments conditions investigated, index values ranging from 6 10 0 scale. At same time, some more conducive growth regional species, measured biodiversity, which ranged 2 14 species different effective than others, costs 19% 106% concrete lined swales.
