Most surface water in the Murray-Darling Basin is used for agricultural activity, and groundwater extraction is accelerating. We cannot yet predict how these water resources will be affected by climate change, partly because Australian climate models do not represent key interactions between small and large scale rainfall changes, and interactions between ground water, the land surface and the atmosphere. This project will produce the first climate simulations that explicitly include these interactions. This will allow a better understanding of future changes to groundwater resources. This understanding will help us plan ahead, and enable new research to help Australia maintain food security in an uncertain future.

墨累-达令盆地的大部分地表水用于农业活动，地下水开采正在加速。我们尚无法预测这些水资源将如何受到气候变化的影响，部分原因是澳大利亚的气候模型并不能代表小规模和大规模降雨变化之间的关键相互作用，以及地下水、地表和大气之间的相互作用。该项目将产生第一个明确包含这些相互作用的气候模拟。这将使人们更好地了解地下水资源的未来变化。这种理解将帮助我们提前计划，并开展新的研究，帮助澳大利亚在不确定的未来维持粮食安全。
