Multi‐Source Hydrogeological Investigation, Water Inflow Prediction, and Water–Mud Inrush Risk Zoning for a Strongly Karstified Limestone Tunnel: A Case Study of the Dongyang Tunnel

open access: yesEngineering Reports, Volume 8, Issue 10, October 2026.
Multi‐source hydrogeological investigation identified widespread karst cavities and water‐bearing fractured zones along the Dongyang Tunnel. Comparative inflow prediction yielded a conservative design control value of 1557.61 m3/day, supporting section‐specific water–mud inrush zoning and targeted drilling, grouting, controlled drainage, and ...

Riverbank Erosion Susceptibility Under Varying Sedimentological and Freeze–Thaw Conditions in Cold Climate Regions

open access: yesEarth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Freeze–thaw processes, moisture, and sediment properties control riverbank erosion in boreal–subarctic rivers. Field measurements, geotechnical analyses and monitoring reveal continuous, seasonally driven erosion, while climate projections indicate reduced freezing, potentially increasing erosion risk under warming conditions.

Numerical Assessment of Borehole Stability and Spalling Behavior for Deep Borehole Disposal Using the PFC2D-SNBV Model

open access: yes
: Deep Borehole Disposal (DBD) involves the emplacement of high-level radioactive waste at depths of 3–5 km in crystalline rock, where elevated in-situ stress and long-term decay heat may influence borehole stability.

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

open access: yesJournal of Quaternary Science, Volume 41, Issue 7, Page 1020-1035, October 2026.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a
