*3.5. Whole-of-Life Modelling*

The modelling experiment 11(1D) aims to show the sensitivity of the irrigation whole-of-life recharge to *Ks*2*v*. The PerTy3 model is implemented with the following values for *Ks*2*v*: (a) 0.1 (b) 0.05 (c) 0.03 (d) 0.01 cm/day. The perching conditions show the full range of behaviour over this range of *Ks*2*v*: The irrigation accession is varied from 10 to 400 to 150 to 100 to 50 mm/year, separated by 5 years. This should provide some insight on the interaction between *IA* and *Ks*2*<sup>v</sup>* and whether the groundwater response may be able to be used to calibrate soil parameters.
