Transport Mechanisms of Conservative Contaminants From Tidally Influenced Semi‐Confined Aquifers to the Sea

Geophysical Research Letters
Groundwater contamination in confined aquifers is an increasingly critical issue, yet the dynamic processes governing contaminant transport between semi‐confined aquifers and the ocean remain insufficiently understood. This study explores these processes

Groundwater level fluctuation caused by tide and groundwater pumping in coastal multi-layer aquifer system

Frontiers in Marine Science
This paper considered the groundwater head fluctuation induced by tide and pumping in the coastal multi-layered aquifer system. The multi-layered aquifer system comprises an unconfined aquifer, an upper confined aquifer, and a lower confined aquifer.

Subterranean environments contribute to three‐quarters of classified ecosystem services

Biological Reviews, Volume 101, Issue 3, Page 1582-1605, June 2026.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Salted Peat: The Forgotten Casualty of Rising Sea Level in Freshwater Coastal Tropical Peatlands

Global Change Biology Communications, Volume 1, Issue 2, June 2026.
This paper invites reflection on the largely overlooked risk that rising sea levels may salinize coastal tropical peatlands, potentially destabilizing vegetation, carbon cycling, and livelihoods. By synthesizing emerging evidence, it highlights a critical blind spot in climate models and adaptation frameworks that warrant urgent scientific and policy ...

Multi‐Objective Calibration of an Ecohydrological Model for Discharge, Phosphorus and Sediment Dynamics in a German Lowland Catchment

Hydrological Processes, Volume 40, Issue 6, June 2026.
This study applies a multi‐objective, multi‐metric calibration framework of SWAT+ for discharge, total phosphorus, and sediment in a flat, tile‐drained lowland catchment, testing alternative calibration and model‐selection strategies with 10 000 parameter sets.

Hydrological Evolution of a Small Watershed Over Nearly a Century of Pumping

Hydrological Processes, Volume 40, Issue 6, June 2026.
The results show that climate and pumping interacted to influence subsurface storage changes in Bertrand Creek Watershed, while aquifer to stream discharge and streamflow declined significantly due to pumping. It also highlights the 1970s as a tipping point in the watershed, marked by significant hydrological change, mostly due to the introduction of ...

Recent trends in groundwater levels in a highly seasonal hydrological system: the Ganges-Brahmaputra-Meghna Delta [PDF]

Hydrology and Earth System Sciences, 2009
Groundwater levels in shallow aquifers underlying Asian mega-deltas are characterized by strong seasonal variations associated with monsoon rainfall. To resolve trend and seasonal components in weekly groundwater levels in the Ganges-Brahmaputra-Meghna ...

An Isotope‐Based Snapshot Reveals the Combined Influence of High‐Elevation Recharge and Local Return Flows on Groundwater Across Guatemala City

Hydrological Processes, Volume 40, Issue 6, June 2026.
Representation (not to scale) of potential high elevation recharge and low elevation return flows within the Guatemala City metropolitan area. ABSTRACT Guatemala City is the most populous urban center in Central America. In this urban center, groundwater extraction within the last 40 years has substantially declined water table levels and accelerated ...

Revealing Tidal Pumping Processes of Alternating Groundwater Discharge and Tidal Intrusion Using Vertical Temperature Analysis Along an Estuarine Interface

Hydrological Processes, Volume 40, Issue 6, June 2026.
Temperature with depth measurements were used to model heat transport associated with sub‐daily changes in bidirectional hydrological fluxes. Tidal pumping along the shoreline, of alternating patterns of tidal intrusion during high tide and groundwater discharge during low tide, was modelled using a recursive estimation state‐space model.
