Sinkhole Flooding and Aquifer Recharge in Arid to Dry Sub-Humid Regions: A Systematic Review in the Perspective of Climate Change

Hydrology, 2022
On the one hand, Sinkhole Flooding (SF) is an essential hydrological process to recharge karst aquifer in arid to dry sub-humid regions. On the other hand, the increase of rain extremes is one of the major consequences of global warming, together with ...

Tracer Test as a Tool for Optimizing the Flow Patterns and Efficiency of a Full‐Scale Drainage Water Treatment Wetland

Water and Environment Journal, EarlyView.
Tracer testing assessed hydraulics and nitrate removal in three full‐scale agricultural drainage treatment wetlands over 3.5 years (three tests). The first test showed rapid, short‐circuited flow and low residence time. After modifying the collection system, the second test increased residence time from 1 to 7 days.

A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

Water and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

The Earth's Greatest Porous Media

Perspectives 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?

Multidimensional Insights Into the Drivers of Aquatic CO2 Dynamics: A River–Reservoir–Wetland Aquatic Continuum Study Within a Semi‐Arid Region

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Evaluating multiple competing biotic and abiotic processes and how they interact with carbon dioxide (CO2) in aquatic systems, is critical to understanding regional and global carbon cycles. Here, we used an aquatic continuum of the Bahe watershed, within a semi‐arid region, to establish a comprehensive conceptual framework for identifying CO2

Role of Unsaturated Zone on Aquifer Leakage–Assessed With Tidal Response

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tidal response analysis is widely used to evaluate aquifer systems, but traditional models that neglect the unsaturated zone often underestimate groundwater leakage. This study develops a new analytical model for tidal analysis that incorporates unsaturated zone effects and explained leakage patterns that traditional models could not resolve ...

Mapping the Interannual Variability of Irrigated Area Using Categorical Sampling and Machine Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Accurate irrigated area (IA) mapping is essential for hydrological and climate modeling. However, existing IA mapping approaches typically rely on persistently irrigated or non‐irrigated samples, which has reduced sensitivity to year‐to‐year IA variability.

Quantification of ground surface movements on sorted circles using time‐lapse structure‐from‐motion photogrammetry in a karst cave, Slovenia

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
We present ground surface movements on sorted circles in a karst cave using time‐lapse photogrammetry with accuracies of up to ±2 mm. Data with 3‐hourly resolution revealed average vertical movements of up to 50 mm and horizontal movements of up to 15 mm during individual freeze–thaw cycles.

Predictive Modeling of Prehistoric Site Distribution in the Southeastern Sulawesi Karst Landscape Using MaxEnt

Journal of Open Archaeology Data
This study employs a predictive modeling approach using the MaxEnt (Maximum Entropy) algorithm to estimate the potential distribution of prehistoric archaeological sites across the karst landscape of the southeastern arm of Sulawesi Island.
