Ensemble Methods for History Matching and Uncertainty Quantification With a Watershed Model

JAWRA Journal of the American Water Resources Association, Volume 62, Issue 1, February 2026.
ABSTRACT History matching of large hydrologic models is challenging due to data sparsity and non‐unique process combinations (and associated parameters) that can produce similar model predictions. We develop an ensemble‐based history matching (and uncertainty quantification) approach using an iterative ensemble smoother (iES) method for three cutouts ...

Seismic Velocity Variations, Ground Deformation and the Role of Fluids During a Low‐Energy Seismic Swarm

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract On March 9th $9\mathrm{th}$, 2023, three small earthquakes (3.8≤Mw≤4.5) $(3.8\le {M}_{w}\le 4.5)$ occurred near Umbertide (Central Italy), within 4 hours. Analyzing seismic ambient noise in the frequency band 0.1–1 Hz from six seismometers within 20 km of the Mw 4.5, we detect a significant drop in seismic velocity at the time of occurrence of

Frozen Ground Induces Seawater Retreat in Coastal Unconfined Aquifers

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract While seawater intrusion (SWI) in coastal aquifers has been extensively investigated, most studies focused on unfrozen conditions. In many cold regions, frozen ground is common, yet its impact on SWI remains poorly understood. Here, we demonstrate that the formation of frozen ground alters salinity distribution in coastal unconfined aquifers ...

Alternative Formulations of the Watertable Fluctuation Method of Recharge Estimation: A Quantitative Comparison

ARC Geophysical Research
Groundwater recharge estimation is vital for ensuring the sustainable management of water resources and the protection of ecosystems. The watertable fluctuation method (WTFM) is commonly used to estimate distributed groundwater recharge in unconfined ...
