Short summary
Floodplains can be constructed along agricultural streams with the purpose of increasing water residence time, thereby reducing instream erosion and intercepting nutrient export. In this paper we show how this remediation measure can reduce phosphorus concentrations by up to 30 % through optimized floodplain designs and placement. These reductions were primarily facilitated by protection against erosion rather than by the promotion of deposition on floodplains.
