Supplemental table and figure for "Evaluation of Winter Hydrology Performance of Three Field-Scale Models"

The deterioration of Lake Erie's water quality is one of the major concerns in North America. A considerable percentage of annual phosphorus runoff occurs during the non-growing season in cold agricultural regions such as those in the Great Lakes region. Consequently, without accurate simulation of water flow during cold periods, reliable modeling of sediment and nutrient loads to surface water bodies is not achievable. Three hydrological models (EPIC, SHAW, and DRAINMOD) were evaluated for their capacity to predict winter tile flow and to highlight the significant processes that have a larger effect on runoff simulation at a field site in Southern Ontario, Canada.
