Performance of DRAINWAT model in assessing the drainage discharge from a small watershed in the Po Valley (Northern Italy)
Abstract
The performance of DRAINWAT, a DRAINMOD based-watershed scale hydrology model, in predicting the water discharge was assessed in a small basin in Northern Italy during 2002-2005. DRAINWAT slightly unpredicted (4%) the total stream drainage flow respect the measured data (549 mm), in calibration (2002-04). The underprediction was 11% in 2004-05 validation period, when snowfall occurred in winter time.
