Title:
Great Artesian Basin transient groundwater model
Publication Date:
26/09/2006
Description:
The Great Artesian Basin is a valuable water resource in Australia's arid interior. The aquifers are recharged along the elevated margins of the basin, which creates high pressures in the aquifer further inland. This causes flowing artesian conditions when deep bores are drilled into the aquifer. The artesian water initially discharged with great force, but as groundwater development has increased the pressure heads in the aquifer have decreased and this has caused many of the bores to stop flowing. The Commonwealth and State sponsored Great Artesian Basin Sustainability Initiative is reducing water wastage and addressing the issue of decreasing pressures by rehabilitating bores and replacing open drains with pipes for water distribution. To manage the water sustainably an understanding of the hydrodynamics of the Basin is required. This report builds on the scientific studies of the Basin undertaken by the Bureau of Rural Sciences and its predecessors since the 1970s. This study describes the development of a time-varying numerical groundwater model that can be used to predict the effects on pressure heads of changes to bore discharge rates. Data required for the modelling were generously provided by State government agencies but were generally collected for other purposes. The model water balance indicates that the current rate of water use exceeds the rate of groundwater recharge. Groundwater levels will continue to fall until this is reversed
