This research, underway at the University of Guelphs School of Engineering, studies the feasibility of modeling phosphorus assimilative capacity by stormwater wetlands in cold climates. The Hidden Valley wetland, located in Kitchener, Ontario, Canada, is an 18 ha natural Typha marsh that receives stonnwater drainage from a 130 ha light industrial and commercial complex. In this study, the capability of the US EPA's Water Quality Analysis Simulation Program v.5 (WASP5) to model the phosphorus dynamics in a wetland system is evaluated. WASP5 was enhanced by incorporating a vegetation growth/phosphorus uptake module called ECOL into the existing water quality simulation routines. This paper addresses the feasibility of using this enhanced simulation tool, called WASP5E herein, to evaluate the impact of alternative management strategies on phosphorus removal in the wetland.
