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

Engineering 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 ...

Effective Evaluation Methods for Fractured Tight Sandstone Reservoirs in Kuqa Depression

Cejing jishu
The multi-genetic fracture in Kuqa depression of Tarim basin provide effective reservoir space and permeability pathways for the reservoir, and the matrix rock blocks have small porosity, making it a typical fractured tight sandstone reservoir.

A Comparison of Screening Methods for Assessing Legacy Wells Within CO2 Storage Licences: Application to Offshore Norway

Greenhouse Gases: Science and Technology, Volume 16, Issue 5, Page 746-757, October 2026.
ABSTRACT Legacy wells represent a critical consideration for offshore CO2 storage projects, as they may provide potential pathways for fluid or gas migration if poorly constructed, undocumented or inadequately abandoned. Systematically assessing large numbers of legacy wells remains challenging due to heterogeneous data availability and the diversity ...

Mineral composition and pore structure on spontaneous imbibition in tight sandstone reservoirs

Scientific Reports
The pore structure of tight oil reservoirs is extremely complex, with a wide range of pore sizes, diverse pore types, and well-developed nanopores and throats. Although researchers have conducted in-depth studies on the mechanism of spontaneous imbibition, issues such as low recovery and short imbibition distance have not been well explained.

A Study on the Distribution Characteristics of Salinity and Nutrients and the Migration Mechanism of Soil Salt in the Delingha Saline‐Alkali Soil Profile of the Qaidam Basin

Land Degradation &Development, Volume 37, Issue 16, Page 11867-11884, October 2026.
ABSTRACT Soil salinization negatively impacts the economic development and ecological environment, particularly in the arid and semiarid regions of China. The Qaidam Basin constitutes a major distribution area of saline‐alkali land in the country. However, the distribution patterns of salinity and nutrients within soil profiles and the underlying salt ...

Quantification of flash flood peaks using computer simulation for potential hill torrents of Pakistan: A modeling study

River, Volume 5, Issue 3, Page 432-452, August 2026.
Abstract This study investigates rainfall runoff behavior of five major torrential Nullahs' of Dera Ghazi Khan (D. G. Khan) for flash flood events. The integration, and fusion of satellite‐based meteorological, topographical, and pedo‐transferred function's (PTF) derived soil hydraulic datasets at 250 m grid size substantially proves a viable approach ...

Integrated hydrologic and hydrodynamic modeling for flood hazard assessment in Ajay River Basin, West Bengal, India

River, Volume 5, Issue 3, Page 465-483, August 2026.
Abstract The Ajay River, originating from the Chotanagpur Plateau (Bihar) and flowing through Jharkhand into West Bengal before merging with the Bhagirathi‐Hugli near Katwa, is among the most flood‐prone rivers in the region. Its lower reaches frequently experience rainfall‐induced flooding and embankment breaches during the mid‐ to late‐monsoon season.

Contrasting Groundwater Response to Surface Water Shortages in the Upper and Lower Colorado River Basins

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Groundwater plays a critical role in sustaining the water supply in the Colorado River Basin (CRB), a region experiencing persistent drought, population growth, and increasing water demand. Using GRACE/GRACE‐FO satellite observations combined with hydrological data sets, we analyze basin‐scale variations and long‐term trends in terrestrial and

Subduction Recycling and Closure of the Paleo‐Asian Ocean in the Beishan Orogen: Constraints From the Niujuanzi Ophiolitic Mélange and Associated Intrusions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Ophiolitic mélanges and associated intrusions provide key archives for reconstructing the evolution of ancient ocean basins and subduction‐related mantle modification. The Hongliuhe–Niujuanzi–Xichangjing ophiolitic mélange in the central Beishan Orogen preserves important records of the Paleo‐Asian Ocean, but the timing of oceanic subduction ...

An Ediacaran Metasedimentary Fragment With Northern Gondwana Affinity in the Southern East Kunlun Accretionary Belt, Northern Tibetan Plateau: Implications for the Dispersal of Peri‐Gondwanan Terranes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Precambrian supercontinent reconstructions largely rely on robust geological constraints. Among these, the basin affinities recorded by Precambrian sedimentary fragments preserved in orogenic belts provide critical evidence for resolving the paleogeographic configurations of microcontinents and continental blocks.
