The papers trace a progression from analytical well hydraulics to delayed-response interpretation, transformation uncertainty, and groundwater-influenced energy decisions.
Published papers remain part of the formal record. This companion series returns to selected studies with later evidence and experience: what still holds, what I would test differently, and which unanswered questions shaped the next stage of the research.

The method maps which places and forecast times most influence a tropical-cyclone intensity prediction, helping researchers judge whether the model relies on physically sensible signals.
Stochastic Environmental Research and Risk Assessment · Published
The analysis keeps grout heat storage in a thermal response test and separates early-time grout effects from later-time ground-conductivity information.
Case Studies in Thermal Engineering · Published
Two groundwater processes can respond at different rates. Accounting for both reconciles the observed amplitude attenuation and phase shift of periodic head signals at the two field sites.

A simplified fault interface reproduces the full two-dimensional drawdown closely for most tested conditions when the fault is not too wide, making it useful for rapid analysis.

At the tested sites, allowing groundwater flux and hydraulic gradient to adjust at different rates improved the pumping-test interpretation and changed the inferred response times.
Journal of Hydrology · Published
A stream does not supply a pumping well instantly or indefinitely. Including finite stream storage and delayed exchange improves the field interpretation, especially for smaller streams and certain time periods.

Using drawdown from several observation wells, the method recovered a nearby hydraulic boundary together with aquifer transmissivity and storage; three wells performed about as well as four.
Journal of Hydrology · Published
Accounting for short well screens and low-permeability layer boundaries produced more plausible aquifer properties at the field site than assuming fully penetrating wells.
Journal of Hydrology · Published
The water-table condition keeps a time scale for gravity drainage, which helps avoid treating unsaturated flow as instantaneous by default.

This technical reply shows that the published transport solution gives the wrong long-time concentration and identifies the equations that require correction.

A physics-informed neural network reconstructed the tested wave fields accurately from incomplete and noisy data after its spatial and temporal scales were optimized.
Mathematics · Published
For a highly permeable well skin, head remains continuous but flux can change across the interface; the usual low-permeability skin condition is therefore not valid.

A simplified interface captures the main drawdown behavior of a fully resolved high-permeability zone around a well while requiring less computation.

For the tested borehole thermal energy storage systems, image wells matched finite-element temperatures at much lower computational cost and revealed how boundaries alter heat storage.
Heat Transfer · Published
A lagging-response model inferred plausible unconfined-aquifer properties from groundwater levels even when detailed pumping rates and well locations were unavailable.
Water Resources Research · Published
Because a stream stores only a finite amount of water, its stage changes during pumping and its support to the well weakens with time.

Including both near-well skin and rate-dependent well loss reproduces the sharp peaks in the field data that simpler well models miss.

In the dual-porosity model, stronger exchange shifts more of the response into fractures and less into the rock matrix near the coast.

Soil type and the lower thermal boundary increasingly affect temperature profiles over time; ignoring the lower boundary can bias groundwater-flux estimates.

When flux responds more slowly than hydraulic gradient, pumping can produce wave-like drawdown and temporary recharge overshoot; when storage responds more slowly, the behavior resembles delayed drainage or dual porosity.

Temperature profiles provide time-varying estimates of vertical groundwater flux instead of imposing a constant-flux condition.
