Abstract The sustainability of groundwater extraction for irrigated agriculture, pastoral land management and commercial industry in the Roper region of the Tindall Limestone Aquifer, is projected by analysing all aspects of water recharge and the movement of underground water through the various rock strata. Recent development in the region has provided additional data, including yearly aquifer recharge and bore yields from in situ borehole pumping and drawdown tests. This information enables increased accuracy when assessing the capacity for sustainable water extraction, while allowing for supplementary justification of water allocations in the Mataranka sub-region. Previous analysis of neoteric results and sparse data have provided novel predictions for future water extraction limits and rates. However, the recent development in the region and availability of new data now enables an increase in accuracy when facilitating modelling to provide an assessment of the sustainable capacity of the Tindall Limestone Aquifer in the area of interest.

Formerly there has been limited knowledge of groundwater levels, quantity and quality of water in the Roper region, resulting in theoretical estimates based on computer modelling projections. Although these projections are proficient enough to provide a guide to water allocation planning they are not capable of providing an accurate sustainable water usage assessment for the region, due to the limited data set. The recent new neoteric data availability in the region has allowed further analysis and assessments of the Tindall Limestone Aquifer to be conducted through the use of AQUAVEO’s GMS MODFLOW. Throughout the creation of the MODFLOW model using the new raw data, it was paramount that the model would realistically reflect the sites conceptualised objects in the simulation. Deliberate use of data sets of different information densities (e.g. with respect to the grid refinements used for the surface digital elevation model) combined with the new information allows for an increase in accuracy and future innovation in the face of sparse data in remote locations when assessing groundwater sustainability levels. The increase in reliability of assessment of the capacity and capability for groundwater extraction in the Tindall Limestone Aquifer Mataranka, assists in ensuring the ongoing integrity of the underground water resource while combining sustainable development in the region.
