This 4 Panel graph shows the effects of varying input parameters -- effective tile drain diameter, depth to tile drain from surface, depth to impervious layer, and hydraulic conductivity correction factor -- on the objective function drain discharge in a 2D, variably-saturated flow model.
The 2D-flow model was run several times while varying the selected input parameters. The output files were imported as ASCII files into Origin and plotted as a 4 Panel graph.
