The model parameters table is partly filled out automatically. AutoCal lists all the parameters recognised for optimisation and allows the user to specify Name, Parameter type, Initial Value, Lower bound, Upper bound and Transformation. The four parameters are given the names Recharge, HHydrCond_layer1, VHydrCond_layer1 and HHydrCond_layer2 respectively.
For Recharge the Parameter type is set to Variable. Its value can vary between 5 [mm] and 12 [mm] with an initial value of 8 [mm]. The transformation is set to real.
For HHydrCond_layer1 the Parameter type is set to Variable. Its value can vary between 0.001 [m/s] and 0.006 [m/s] with an initial value of 0.0022 [m/s]. The transformation is set to logarithmic.
For VHydrCond_layer1 the Parameter type is set to Dependent. In fact, in the current example, the vertical hydraulic conductivity relates to the horizontal hydraulic conductivity according to the following equation 0.1*HHydrCond_layer1. Neither Upper/Lower bound nor initial value need to be specified. The transformation is set to logarithmic.
For HHydrCond_layer2 the Parameter type is set to Variable. Its value can vary between 0.0005 [m/s] and 0.004 [m/s] with an initial value of 0.0015 [m/s]. The transformation is set to logarithmic.
In Keyword/Line no, which is filled out automatically, you can see where the parameter being optimized is located.
