The regional analytic element groundwater model (GW AEM) has 15 parameters that are included in the sensitivity and uncertainty analysis. The parameters govern the stochastic elements of the conceptual model, such as the coal seams and faults and the hydraulic properties of the coal seams, interburden and faults.

In the alluvial Avon and Karuah MODFLOW models, six parameters are allowed to vary. These include the hydraulic properties of the alluvium and the weathered zone, the riverbed conductance, recharge and a constant head offset that represents the interaction with the deeper basin. Hydraulic properties are assumed to be spatially uniform.
