Technical Abstract: Accurate simulation of water transport (percolate, runoff, soil water content) under various management practices is important to accurately simulate water quality. Furthermore, simulation of macropore flow can be important to accurately simulate chemical transport to shallow groundwater. Therefore, we compared RZWQM simulated water transport to 80 days of data from two macroporous field plots (a short term no-till plot and a rototilled plot). The only calibrated parameters were the average macropore radius and the surface crust saturated hydraulic conductivity. The other parameters were determined from the literature or measured. The results indicate that RZWQM reasonably simulated runoff, percolate, and soil water content compared to daily observations with minimal calibration and reasonable input parameters.
