The Current values have been imported from a PEST optimization run. They are relatively close to the default parameters which have been obtained from an earlier manual calibration effort. The newly obtained parameters can be made the Default parameters by clicking on Replace Defaults Values with Current.

This control panel may also be used to conduct parameter sensitivity analyses without loosing the original default parameter values. Simply modify Current values, conduct a model run, and restore the current values to the default values by clicking the button Replace Current Values with Defaults.
