“…Problems can also arise when data sets are split between different agencies. Fundamental groundwater data (stratigraphy, bore construction, hydraulic head, major ion chemistry) are available in State and Territory databases which are publicly available and user-friendly (Sharples et al, 2020). The Bureau of Meteorology has the responsibility of collating groundwater data into a single database (Bureau of Meteorology, 2022), although not all the data in State and Territory databases are represented in the national database.…”

“…Methods for trend analysis of groundwater levels abound in the literature and span from classical statistical approaches (e.g., linear analysis, Mann-Kendall/Kendall's tau, Sen's slope [1,2,[6][7][8][9]) to more recent and sophisticated techniques using deep learning and unsupervised learning for data reduction and visualization [10].…”

“…Burkett and Kelly [24] analyzed the groundwater level trend in the Lachlan aquifer for the period 1988-2008 using the same approach as [22], identifying specific hotspots with groundwater level declines between 10 and 30 m. They also identified areas with no substantial declines for the period analyzed, thus highlighting the importance of spatial patterns and the occurrence of zones of high groundwater withdrawals. Finally, recently the Australian Bureau of Meteorology [6] has developed a continental scale tool to visualize information on 5-, 10-and 20-year groundwater level trends (from year 2000 onwards) from upper aquifers, which can be associated with the alluvial aquifers shown in Figure 1. These trends are calculated using a linear regression fitting over the annual groundwater level recovery peak [6].…”

Groundwater levels represent the aggregation of different hydrological processes acting at multiple spatial and temporal scales within aquifer systems. Analyzing trends in groundwater levels is therefore essential to quantify available groundwater resources for beneficial use, and to devise plans/policies to better manage these resources. In this work, three trend analysis methods are employed to detect long-term (1971–2021) trends in annual mean/minimum/maximum depth to water table (DTW) at 910 bores. This analysis is performed in eight main alluvial systems in the Murray–Darling Basin (MDB), Australia, which concentrate nearly 75% of groundwater use. The results show: (a) an overall increasing trend in DTW across alluvial aquifers attributable to changes in recharge from rainfall and groundwater extraction; (b) the analysis methods employed show similar statistical significances and magnitudes, but differences exist; (c) the annual minimum DTW has a smaller trend magnitude than annual mean DTW, and the annual maximum DTW has a larger trend magnitude than mean DTW; (d) trends in annual rainfall and potential evaporation, and cumulative number of production bores, are consistent with the groundwater trends; (e) irrigation is responsible for some of the decreasing trend in groundwater level. These results could be used to target further research and monitoring programs, and inform groundwater resource management decisions in the MDB.

The Murray-Darling Basin (MDB) is a highly allocated and regulated, mostly semiarid basin in south-eastern Australia, where groundwater is a significant water resource. Future climate predictions for the MDB include an expansion of arid and semiarid climate zones to replace temperate areas. The impacts of climate change are already evident in declining groundwater levels and changes in the connection status between rivers and groundwater, and modelling has predicted a further reduction in future groundwater recharge and ongoing declines in groundwater levels. This is predicted to further reduce river baseflow and negatively impact groundwater-dependent ecosystems (GDEs), and these system responses to a changing climate and extreme events are complex and not always well understood. This report provides an overview of the current state of knowledge of groundwater response to a changing climate for the MDB, and outlines challenges and opportunities for future groundwater research and management. Opportunities for the region include improving data systems and acquisition through automation and novel data sources, and growing capability in integrated, risk-based modelling. Quantification of the groundwater/surface-water connection response to declining groundwater levels, and assessing GDE water requirements and thresholds, would enable identification of vulnerable systems and inform the development of metrics for adaptive management, improving the ability to respond to climate extremes. There is potential to adapt policy to support active management of groundwater where required, including conjunctive use and water banking. Improving knowledge sharing and water literacy, including understanding community values of groundwater and GDEs, would support future decision-making.
