AB: Physically based hydrologic models, when properly applied, provide the framework to easily evaluate baseflow and interflow contributions to total runoff. However, the data available for the calibration procedure are often limited to streamflow and only under the best conditions a few point measurements of groundwater heads and soil moisture values are available to enhance the procedure. A methodology of incorporating particle tracking into a fully distributed hydrologic model is investigated as the means of providing an extra layer of calibration data and increased confidence in overall model performance. The objective of this research is to determine if such a combined model formulation can be used to improve model calibration and under what conditions is this formulation beneficial. The implications for quantifying contributions of "old" versus "new" water to increased runoff are also evaluated.
