Unsustainable rates of groundwater (GW) depletion make GW management a priority. Effective GW management is hindered by the uncertainty in the predictions of aquifer models, but the increase of geodetic surface deformation data can improve aquifer characterization. We integrate surface deformation measurements into a Bayesian inference framework to infer aquifer permeability in a poroelastic model. We demonstrate the applicability of this technique using a Nevada pumping test with both Interferometric Synthetic Aperture Radar (InSAR) and Global Positioning System (GPS) surface deformation data. We infer the lateral permeability variations in the aquifer with high spatial resolution and identify the information content of each data set. For the Nevada case, a single InSAR surface deformation map provides significantly more information than multiple GPS time series. As the availability of global InSAR data continues to grow, geomechanical inversion of geodetic surface deformation data will become a valuable technique for aquifer characterization and management.
The High Plains Aquifer (HPA) is a critical water resource in the Central United States, yet its depletion remains a major concern. While the Gravity Recovery and Climate Experiment (GRACE) satellite mission provides large-scale estimates of liquid water equivalent thickness (LWET), its coarse spatial resolution (appro...
In recent years, many global geopotential models (GGMs) have been produced by various international organizations by combining satellite, airborne, terrestrial gravity, marine gravity anomaly, and altimetry data. These models provide a consistent mathematical description of Earth’s gravity field, enabling the calcu...

Groundwater-induced land subsidence is one of the most widespread geohazards associated with excessive groundwater exploitation, characterized by broad spatial extent and significant socio-economic impacts. However, conventional point-based monitoring techniques are unable to characterize the regional distribution of g...

Reliable assessment of liquefaction hazard, particularly in the context of groundwater fluctuations associated with hydroclimatic changes and variability between liquefaction assessment methods, necessitates supplementary data and advanced site characterization methods. To understand liquefaction hazard and its relatio...

An accurate gravity map provides fundamental data for geoscience research and enables accurate subsurface interpretation. For many years, prior gravity surveys in the Bromo‑Tengger volcanic complex have been unsuccessful in accurately defining rock units, structural continuity, and caldera boundaries. This study analyz...

The Midyan Basin in the NEOM region of northwestern Saudi Arabia is a promising yet underexplored geothermal province situated within the tectonically active Red Sea Rift and Gulf of Aqaba transform system. Despite evidence of elevated regional heat flow and shallow Curie depths, the structural controls governing geoth...
