Influence of Hydraulic Conductivity Conceptualization and Unsaturated Flow Parameters for an Integrated Hydrological Model

open access: yesWater Resources Research, Volume 61, Issue 11, November 2025.
Abstract In recent decades, integrated hydrologic models (IHMs) have advanced our understanding of hydrologic processes across catchment to continental scales. These models couple surface and variably saturated subsurface flow, incorporating land surface models to represent interactions within the critical zone. However, high computational costs hinder

Linking Very Near‐Earth Reconnection (VNERX) to Mid‐Latitude GICs: Evidence From the 7 September 2017 Storm

open access: yesGeophysical Research Letters, Volume 52, Issue 20, 28 October 2025.
Abstract Geomagnetically Induced Currents (GICs) are a hazard to power systems. In this letter, we present a case study to understand why a Sudden‐Commencement‐associated 20A GIC spike, measured at mid‐latitude in Virginia, US, increased to 30A within 2 min of interplanetary shock arrival.

Space Weather Impact on the Scandinavian Interconnected Power Transmission System [PDF]

open access: yes, 2015
Geomagnetic storms (GMS) can seriously affect high voltage transmission power grids. More specifically, GMS can inject geomagnetically induced currents (GICs) into the power network, thus causing instabilities and eventually leading to grid collapse ...

Structure of the Multiphase Chalcolithic Tell Chiselet–Grădiștea Fundeanca (Romania) From SH‐Wave Full‐Waveform Inversion, Borehole Geophysics and Coring

open access: yesArchaeological Prospection, Volume 32, Issue 4, Page 899-926, October/December 2025.
ABSTRACT The emergence and development of settlement mounds, also called tells, is of major interest for the analysis of socio‐economic transformations occurring in the lower Danube plain during the East European Chalcolithic period. In this context, the multiphase chronology and structural layout of tells are highly relevant indicators, but small ...

Long‐Term Peak Geoelectric Field Behavior for Space Weather Hazard Assessment in Alberta, Canada Using Geomagnetic and Magnetotelluric Measurements

open access: yesSpace Weather
To better understand the risks of space weather to electric power transmission networks, magnetometer data and nearby magnetotelluric impedance data at four sites in Alberta, Canada are used to estimate the induced geoelectric field over the last 12–32 ...

Urban Tree Drought Stress: A Practitioner‐Focused Review of Detection and Monitoring Methods

open access: yesHydrological Processes, Volume 39, Issue 10, October 2025.
This paper shows that there is a research gap between leaf‐level stress detection and large‐scale stress monitoring systems for urban trees. The biggest challenge is the detection of early stress symptoms on the individual tree base at the city scale. There are currently no stress detection systems in place, although detecting stress early could help ...
