CloudGMS has been commissioned by DENR to develop a numerical groundwater model of the aquifers within the central area of the WDWCD to improve confidence in the sustainability of the groundwater resources, as this is the area within the WCD with greatest potential for intensive development.

Western Davenport WCD Groundwater Model (v2.0) Appendix CloudGMS 125 to calibrate the model). The cost of such a speed-up strategy is, of course, some reduction in the diversity of the calibration-adjusted random parameter sets thus obtained. The choice of solution space dimensionality was trialled and an optimal value of 2 was determined, a lesser value resulted in a considerable number of runs not being calibrated and a greater value resulted in a reduced range of parameters values in each of the parameter sets. The sensitivity of the objective function to each of the adjustable parameters is presented below in Figure 12-4 a) d) and Figure 12-5 a) d). a) b) c) d) Figure 12-4 Variation in phi compared to adjusted parameters a) horizontal hydraulic conductivity Layer 1, b) vertical hydraulic conductivity Layer 1; c) specific storage Layer 1 and d) specific yield Layer 1.
