Previous groundwater modelling studies Groundwater modelling was conducted within the WDWCD in 2004 by Matthews (CentreFarm) and in 2007 by AGT. The AGT (2007) report presented 3 groundwater models of the Alekerange borefield to examine the long term sustainability of the groundwater source. The location of the groundwater models relative to the current study are presented in Figure 2-3. The model parameters used in the study are summarised below: 2.5.1. Drawdown model The drawdown model domain (Figure 2-3) was established to examine: the potential for drawdown interference between the proposed new borefield and the existing water supply bores at the Ali Curung community; and the separation of production bores within the proposed borefield.
