Due to the impact of extreme climate events, Taiwan has experienced an increase in the frequency of heavy rainfall and drought. To effectively manage the risks posed by climate change, continuous and precise management of groundwater resources is crucial. However, the complex three-dimensional structure of subsurface aquifers limits our understanding of the spatial distribution of groundwater reservoirs. Additionally, there is limited knowledge about groundwater variability across different time scales. By analyzing surface displacements from the Global Navigation Satellite System (GNSS), changes in subsurface wave velocities recorded by seismic stations, and groundwater level time series from the Water Resources Agency, we can gain valuable insights into the deep structure of aquifers, temporal changes in aquifer systems, and variations in terrestrial water storage. This integrated approach enhances our ability to monitor groundwater resources and mitigate the impacts of extreme climate events on Taiwan's water supply
