Assessing the progression of seawater intrusion in the Dradère-Souière coastal aquifer (Northwest Morocco): A hydrogeological, hydrochemical, and geophysical investigation

open access: yesScientific African
Seawater intrusion is a critical issue affecting coastal aquifers worldwide, particularly in regions facing overexploitation and climatic. The Dradère-Souière coastal aquifer, one of the most heavily exploited aquifers in Morocco, is increasingly ...

Selected Physical and Geotechnical Properties of Loess in Wairarapa Valley, New Zealand

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 4, December 2026.
Loess up to 10 m thick covers marine terraces, old river aggradation terraces, and gentle hill country slopes in Wairarapa, New Zealand. In the drier eastern and southern parts of Wairarapa, the loess is subject to dry summer and autumn and wet winter and spring in most years.

The Earth's Greatest Porous Media

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?

Quantifying variations in δ18Ow and salinity in modern Bermudan waters on hourly to monthly timescales

open access: yesFrontiers in Marine Science
Since the mid-1970s, groundwater resources in Bermuda have been explored to supplement growing potable water demand on the island. Much of this work has focused on modeling the shape and size of freshwater lenses beneath the island’s surface, mainly the ...

Four Decades of Research at the MADE Site and Beyond: Advancing the Understanding and Modeling of Solute Transport in Heterogeneous Media

open access: yesReviews of Geophysics, Volume 64, Issue 4, December 2026.
Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

A Robust AHP–GIS Based Flood Susceptibility Mapping Using Stochastic Hill‐Climbing Algorithm

open access: yesJournal of Flood Risk Management, Volume 19, Issue 4, December 2026.
ABSTRACT Flooding is one of the most frequent and devastating natural hazards affecting urban areas globally, leading to considerable social, economic, and environmental impacts. In the present study, a novel framework for flood susceptibility mapping is proposed using the stochastic Hill‐Climbing (SHC) method in the Analytical Hierarchy Process (AHP ...

The South Dunedin coastal aquifer & effect of sea level fluctuations

open access: yes, 2012
The South Dunedin urban area is low-lying having been reclaimed from coastal dunes, marshes and intertidal deposits since European settlement. The water table lies close to the surface, typically 0.3 m to 0.7 m under the urban area.
