Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

Numerical simulation for the 3D seepage flow with fractional derivatives in porous media

open access: yes, 2008
In this paper, the numerical simulation of the 3D seepage flow with fractional derivatives in porous\ud media is considered under two special cases: non-continued seepage flow in uniform media (NCSFUM)\ud and continued seepage flow in non-uniform media ...

Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

open access: yesNear Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Endoscopic Treatment for Esophagogastric Variceal Bleeding in Patients With Acute‐on‐Chronic Liver Failure: An Observational Study

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
In patients with acute‐on‐chronic liver failure (ACLF), esophagogastric variceal bleeding (EGVB) represents a critical complication associated with high short‐term mortality. This study evaluated the efficacy of endoscopic treatment in this specific population and identified prognostic factors associated with 6‐week rebleeding and mortality.

Establishing Long Term Seepage Behavior of Zoned Embankment Dams with Three-Dimensional Seepage Analysis

open access: yes, 2009
Since seepage-related problems are the main cause of more than fourty percent of dam failures, seepage analysis is one of the most important stages in the design process of an embankment dam. Seepage factors must be monitored in the dam’s body, abutments,

In situ loading of a pore network model for quantitative characterization and visualization of gas seepage in coal rocks

open access: yesDeep Underground Science and Engineering
The flow characteristics of coalbed methane (CBM) are influenced by the coal rock fracture network, which serves as the primary gas transport channel. This has a significant effect on the permeability performance of coal reservoirs.

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries

open access: yesPest Management Science, Volume 81, Issue 4, Page 1740-1751, April 2025.
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

Strategies for Assessing Post‐Wildfire Geomorphic Resilience in Semiarid Rivers

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT We review and summarize diverse components of a catchment that can be monitored after wildfire to assess the geomorphic resilience of the river corridor in semiarid regions. We distinguish upland portions of river catchments from river corridors.

Seepage-damage coupling study of the stability of water-filled dump slope

open access: yes, 2014
The stability of water-filled dump slope has been one significant geotechnical engineering problem that needs to be urgently resolved. The coupling effects of seepage and damage on the dump slope are critically important for stability analysis.
