Intense Human Activities Induce the Dynamic Changes of Interaction Pattern Between Karst Water‐Quaternary Groundwater in the Basin‐Mountain Coupling Belt Over the Past 60 Years

Water Resources Research
Karst water are important for water supply and ecological protection. However, climate changes and human activities have caused severe water supply crisis.

Tides of the Midland: From Groundwater Into the River

Hydrological Processes, Volume 40, Issue 8, August 2026.
Tides in a river that is NOT influenced by the ocean, is not in the coastal area and is more than 300 m above sea level are caused by groundwater tides. As the phases of the Moon change, the amplitudes of the streamwater oscillations vary synchronously with those of gravitational acceleration.

Karst groundwater enrichment law in Laiwu Basin

Dizhi lixue xuebao
Objective  The Laiwu Basin is a typical monocline fault basin in the central and southern regions of Shandong Province. It has a complex geological structure and an uneven distribution of groundwater resources within the region. Previous researchers have

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

Near Surface Geophysics, Volume 24, Issue 4, Page 364-391, August 2026.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Spatial Heterogeneity and Nonlinear Influencing Mechanisms of Vegetation Carbon Sequestration Capacity in the Southwest China Karst Region

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Understanding of the spatiotemporal dynamics of vegetation carbon sequestration capacity (VCSC) in Southwest China's contiguous karst region is critical for regional carbon cycling. Using MOD17A3 data from 2001 to 2023, we analyzed spatial heterogeneity in vegetation net primary productivity (NPP) and applied Geodetector to evaluate nonlinear ...

Modeling Transient Flow in Heterogeneous Aquifers With the Mixed Pressure‐Velocity Formulation of Physics Informed Neural Networks

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Physics‐Informed Neural Networks (PINNs) have emerged as a powerful framework for modeling groundwater flow using deep learning neural networks, particularly in scenarios where traditional data‐driven approaches are limited by the scarcity of data.

N-nitrosamines in karst groundwaters in southwestern China: Risks and implications for drinking water safety

Emerging Contaminants
Groundwater is a vital drinking water source for populations in remote karst regions. However, the highly developed karst tube systems facilitate the infiltration of surface wastewater containing N-nitrosamines, raising concerns about groundwater safety.

Classification and Conceptualization of Karst Recharge Processes Through Spectral and Change Point Analysis of Drip Water Dynamics

Water Resources Research, Volume 62, Issue 8, August 2026.
Abstract Karst aquifers are notoriously heterogeneous, making it challenging to characterize recharge dynamics using traditional, static indicators. Percolating (drip) water records, when analyzed at high temporal resolution, offer insights into flow mechanisms in karst vadose zones.

Implicit Neural Representation to Improve the Resolution of 3D Electrical Resistivity

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Electrical resistivity tomography (ERT) is a subsurface imaging geophysical technique. Traditional ERT inversion methods, such as smoothness‐constrained least‐squares approaches, often suffer from discretization artifacts when reconstructing electrical resistivity from resistance measurements.

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

Water and Environment Journal, Volume 40, Issue 3, Page 408-423, August 2026.
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.
