Impacts of coal seam gas (CSG) groundwater abstraction in the Surat Basin in Queensland has drawn huge attention from stakeholders who include sensitive landowners, regulators, civic organization and academia. Monitoring of the perceived impacts has been the focus of CSG mining companies and the stakeholders. This research project aims to develop methodology to integrate InSAR and LiDAR data to determine the rate of ground movement (subsidence) and impacts on groundwater dependent ecosystems (GDEs). Development and testing of machine learning algorithms to improve the methodologies for the determination of the rate of ground subsidence and impacts on GDEs will be attempted. Assessment of the risks posed by the subsidence to infrastructure and GDEs in the study area will be explored.
