The amount of water (flux) entering an aquifer as recharge is a critical factor in determining how water table levels change, the sustainable yields for groundwater extraction, and the impact of extractive industries on groundwater availability. However, the processes that govern this flux remain difficult to quantify, and are therefore considerable sources of uncertainty in modelling the groundwater balance and conducting impact assessments. Due to the geological complexity of the Surat and Bowen Basins, recharge can occur via multiple pathways...

CSG companies and the Queensland Government collect data about the volumes of various types of groundwater use. This data helps estimate groundwater extraction volumes used in groundwater models which inform decisions regarding the management of the industry and plan water allocations. For example, the Queensland Government model is used to identify which private water bores are likely to have declining groundwater levels as a result of CSG industry activities and compensation for water loss is negotiated between the companies and...
