From: Constraining the response of continental-scale groundwater flow to climate change
Comparison between regional flow patterns using water table data from pre-2000 to 2010–2020. (A) streamlines illustrate the change in regional flow pathways from pre-2000 (dark grey) to 2010-2020 (dark red), where the thickness of each streamline indicates the relative velocity. This map was generated from our models using Cartopy 0.19 (https://scitools.org.uk/cartopy). (B) Decline in water levels measured in groundwater boreholes from pre-2000 to 2020. The “agricultural region” is the western portion of the model that comprises part of the Great Artesian Basin (west of 150\(^{\circ }\) longitude between 25–32\(^{\circ }\)S). (C) Flow velocities have increased on average by 10% between 1–2 km depth, which indicates that deeper aquifers of the GAB are recharging alluvial sediments within inland regions to replenish water that has been pumped since 2000.
