These days various types of models are available for non-point Source (NPS) pollution modeling and management. These models can help in identifying critical areas and selecting best management practices to reduce pollutant loads to streams. However, the way the existing models handle spatio-temporal variability of parameter and description of the natural processes make straight forward application difficult. The objective of the present study is to assess the performance of various models to simulate streamflow and sediment yield in Ontario conditions. The NPS models considered include Soil and Water Assessment Tool (SWAT), Hydrological Simulation Program-FORTRAN (HSPF), Annualized Agricultural Non-Point Source (AnnAGNPS); and Areal Non-Point Source Watershed Environmental Response Simulation (ANSWERS-2000). The comparisons of the models result indicate an important difference in the different components of water quality and quantity that is addressed in this paper.(Download PDF) (Export to EndNotes)
