“…These models include HSPF (Bicknell et al, 1995), DUFLOW (van Duin et al, 1995), CE-QUAL-RIV1 (Environmental Lab, 1990), QUAL-2E (Brown and Barnwell, 1985), MIKE12 (Bach and Jensen, 1994), RCA (HydroQual, 1995), and WASP4 (Ambrose et al, 1988). These models simulate P transformations in the water column and sediment for systems that are primarily one-dimensional, downstream transport.…”

Phosphorus (P) is often the key nutrient found to be limiting in both estuarine and freshwater ecosystems. As such, the ability of wetlands and streams to retain P is key to determining downstream water quality. This article reviews the processes and factors regulating P retention in streams and wetlands and evaluates selected methodologies used to estimate P retention in these systems. Phosphorus retention mechanisms reviewed include uptake and release by vegetation, periphyton and microorganisms; sorption and exchange reactions with soils and sediments; chemical precipitation in the water column; and sedimentation and entrainment. These mechanisms exemplify the combined biological, physical, and chemical nature of P retention in wetlands and streams. Methodologies used to estimate P retention include empirical input-output analysis and mass balances, and process kinetics applied at various scales, including micro-and mesocosms to full-scale systems. Although complex numerical models are available to estimate P retention and transport, a simple understanding of P retention at the process level is important, but the overall picture provided by mass balance and kinetic evaluations are often more useful in estimating long-term P retention.
