Abstract
The hydrological and non-point source loading processes of the Big Creek Marsh and Big Creek Watershed were investigated in this study. The Big Creek Watershed in south-western Ontario was modelled with AnnAGNPS (Annualized AGricultural Non-point Source). The AnnAGNPS model was first calibrated and validated with observed streamflow data in the neighbouring Canard River Watershed. Nash-Sutcliffe model efficiencies for monthly streamflow predictions were 0.75 and 0.72, for the calibration and validation periods. In the Big Creek Watershed the north-eastern and south-eastern regions were found to produce the highest sediment and nutrient loads. A water budget model for the Big Creek Marsh was developed to investigate hydrologic historic processes in the wetland. In the model assessment three potential wetland operating plans were reviewed and compared to the observed pumping data. A sensitivity analysis of the water budget model was performed. An investigation of Lake Erie's influence on the Marsh was also included.
