Broad Application Category:hydrologic and pollutant 
Primary Application Category:calibration, sensitivity, and/or uncertainty analysis 
Secondary Application Category:pollutant cycling/loss and transport 
Watershed Description:1,384 km^2 Dender River, located in Flanders region of Belgium. 
Calibration Summary:graphical comparisons between simulated and measured nitrate levels 
Validation Summary: 
General Comments:Study focused on assessing uncertainty related to fertilizer application amounts, planting dates, & harvest dates on predicted nitrate losses. The uncertainty was determined using an efficient Monte Carlo method and latin hypercube sampling. Eight inputs were found to have a significant impact on nitrate concentrations exceeding 3 mg/l. Uncertainity analysis indicated wide uncertainty bounds: 95% ranged from ±50% relative to the average nitrate predictions.
