“…Maximum reduction observed in the watershed outlet was 0.16% and most of the wetlands (96%) had less than 0.04% impact on TP load at the outlet, which was expected due to small size of the wetlands (maximum 8 ha) compared to the total watershed area (16,120 km 2 or 1,612,000 ha). The difference between load reduction at the subwatershed level and the watershed level is also in agreement with previous studies on streamflow and sediment load reduction (Martinez-Martinez et al, 2014;Martinez-Martinez et al, 2015). Table 3 shows the average annual TP load reduction (kg) for the four wetland sizes.…”

“…These values were selected as median rates reported by Kaldec and Wallace (2008). The length to width ratio of 2:1 and wetland depth of 0.3 m were used as recommended by previous studies (Martinez-Martinez et al, 2015). SUSTAIN was run four times, one for each wetland size, for the 2,293 selected subwatersheds resulting in 2293×4 = 9172 total runs.…”

“…In terms of stream order, Marinez-Martinez et al (2014) found that wetlands located on stream order one (headwater), had a much greater impact on peak flow reduction than wetlands located on higher order streams. Martinez-Martinez et al (2015) also evaluated the impact of stream order and distance to outlet of four wetland sizes on sediment load reduction. In terms of distance to outlet, wetlands located at mid-range distance from the outlet had the highest sediment load reduction at the watershed level.…”

“…To overcome the drawbacks in representing wetlands, coupling the SWAT model with the System for Urban Stormwater Treatment and Analysis Integration (SUSTAIN) model (Shoemaker et al, 2009) is recommended, allowing the incorporation of natural wetland performance data into the modeling process (Martinez-Martinez et al, 2015). Martinez-Martinez et al (2015) used coupled SWAT and SUSTAIN models for assessing wetland implementation scenarios on streamflow and sediment load mitigation. However, no modeling study has been conducted on the assessment of wetland impacts on phosphorus reduction.…”

Freshwater resources are vital for human and natural systems. However, anthropogenic activities, such as agricultural practices, have led to the degradation of the quality of these limited resources through pollutant loading. Agricultural Best Management Practices (BMPs), such as wetlands, are recommended as a valuable solution for pollutant removal. However, evaluation of their long-term impacts is difficult and requires modeling since performing in-situ monitoring is expensive and not feasible at the watershed scale. In this study, the impact of natural wetland implementation on total phosphorus reduction was evaluated both at the subwatershed and watershed levels. The study area is the Saginaw River Watershed, which is largest watershed in Michigan. The phosphorus reduction performances of four different wetland sizes (2, 4, 6, and 8 ha) were evaluated within this study area by implementing one wetland at a time in areas identified to have the highest potential for wetland restoration. The subwatershed level phosphorus loads were obtained from a calibrated Soil and Water Assessment Tool (SWAT) model. These loads were then incorporated into a wetland model (System for Urban Stormwater Treatment and Analysis IntegratioN-SUSTAIN) to evaluate phosphorus reduction at the subwatershed level and then the SWAT model was again used to route phosphorus transport to the watershed outlet. Statistical analyses were performed to evaluate the spatial impact of wetland size and placement on phosphorus reduction. Overall, the performance of 2 ha wetlands in total phosphorus reduction was significantly lower than the larger sizes at both the subwatershed and watershed levels. Regarding wetland implementation sites, wetlands located in headwaters and downstream had significantly higher phosphorus reduction than the ones located in the middle of the watershed. More specifically, wetlands implemented at distances ranging from 200 to 250 km and 50-100 km from the outlet had the highest impact on phosphorus reduction at the subwatershed and watershed levels, respectively. A multi criteria decision making (MCDM) method named VIKOR was successfully executed to identify the most suitable wetland size and location for each subwatershed considering the phosphorus reduction and economic cost associated with wetland implementation. The methods introduced in this study can be easily applied to other watersheds for selection and placement of wetlands while considering environmental benefits and economic costs.

“…An application of the approach to a watershed with numerous potholes in North Dakota showed an improved model performance in simulating stream flows at the watershed outlet. Another approach in enhancing SWAT characterization of wetlands is to couple the SWAT model with a United States Environmental Protection Agency (USEPA) field scale model called System for Urban Stormwater Treatment and Analysis Integration (SUSTAIN) that characterizes drained water from upland flow [9,10]. In addition to wetland modules developed in SWAT, improvements have also been made in the semi-distributed Soil and Water Integrated Model (SWIM) [11,12] and the distributed hydrological model HYDROTEL [13,14] through incorporating wetland flow, nutrient, and groundwater related dynamics to characterize wetland processes.…”

A GIS-based fully-distributed model, IMWEBs-Wetland (Integrated Modelling for Watershed Evaluation of BMPs-Wetland), is developed to simulate hydrologic processes of site-specific wetlands in an agricultural watershed. This model, powered by the open-source GIS Whitebox Geospatial Analysis Tools (GAT) and advanced database technologies, allows users to simulate and assess water quantity and quality effects of individual wetlands at site and watershed scales. A case study of the modelling system is conducted in a subbasin of the Broughton's Creek Watershed in southern Manitoba of Canada. Modelling results show that the model is capable of simulating wetland processes in a complex watershed with various land management practices. The IMWEBs-Wetland model is unique in simulating the water quantity and quality effects of individual wetlands, which can be used to examine location-specific targeting of wetland retention and restoration at a watershed scale.
