Hydrologic and water quality performance of four bioretention cells in Central North Carolina, USA

, L. J. Sharkey, J.T. Smith, W.G. Lord & A.R. Jarrett
Two paired, field-scale bioretention studies (in Greensboro and Louisburg, NC, USA) have been conducted to study (1) hydrologic performance and (2) nutrient removal of phosphorus and nitrogen. In Greensboro, one cell was conventionally drained; the other contains a zone of internal water saturation (IWS) of 0.45m. They were continuously monitored from June, 2002, to December, 2004. During outflow events, TP concentrations were significantly lower (P<0.01) in the cell with an IWS zone, but these results...
