Analytical and numerical adjoint solutions for cumulative streamflow depletion Open
Streamflow depletion is traditionally defined as the instantaneous change in the volumetric rate of aquifer–stream exchange after a finite period of continuous groundwater extraction. In the present study an alternative metric of streamflo…

A multi-stage screening approach to evaluate risks from inter-aquifer leakage associated with gas well and water bore integrity failure Open
Integrity failure of wells in gas resource developments poses a potential risk to groundwater resource quality and quantity by enhancing the connectivity and fluid migration between a gas reservoir and overlying aquifers, which may support…

Fault-Related Fluid Flow Implications for Unconventional Hydrocarbon Development, Beetaloo Sub-Basin (Northern Territory, Australia) Open
This study assesses potential geological connections between the unconventional petroleum plays in the Beetaloo Sub-basin, regional aquifers in overlying basins, and the near surface water assets in the Beetaloo Sub-basin Northern Territor…

An integrated hydrogeophysical and hydrogeological approach to underpin the long-term water security of a remote tropical island Open
Groundwater resources that sustain small Indigenous communities in remote parts of northern Australia are often poorly characterised, in part due to their remoteness and the economics of undertaking field investigations. The Warruwi commun…

A new Python package to estimate hydraulic and poroelastic groundwater properties using standard pressure records Open
<p>Determining subsurface hydraulic and geomechanical properties crucially underpins groundwater resource investigation and management. While standard practice relies on active testing, passive approaches require less effort and cost…

Comparing Methods of Barometric Efficiency Characterization for Specific Storage Estimation Open
Groundwater responses to barometric pressure fluctuations are characterized using the concept of barometric efficiency (BE). For semiconfined and confined aquifers, BE values can be used to provide efficient, low‐cost estimates of specific…

When to Account for Boundary Conditions in Estimating Hydraulic Properties from Head Observations? Open
Explicitly accounting for uncertainty in boundary conditions during calibration and uncertainty analysis invariably means increasing the complexity of a model. This increases computational requirements, as more parameters imply more model …
