4D Physics‐Based Pore Pressure Monitoring Using Passive Image Interferometry [PDF]

Geophysical Research Letters, 2023
This study introduces a technique for four‐dimensional pore pressure monitoring using passive image interferometry. Surface‐wave velocity changes as a function of frequency are directly linked to depth variations of pore pressure changes through ...

Physics-Based Relationship for Pore Pressure and Vertical Stress Monitoring Using Seismic Velocity Variations

Remote Sensing, 2021
Previous studies examining the relationship between the groundwater table and seismic velocities have been guided by empirical relationships only. Here, we develop a physics-based model relating fluctuations in groundwater table and pore pressure with ...

Neural network models for seabed stability: a deep learning approach to wave-induced pore pressure prediction

Frontiers in Marine Science, 2023
Wave cyclic loading in submarine sediments can lead to pore pressure accumulation, causing geohazards and compromising seabed stability. Accurate prediction of long-term wave-induced pore pressure is essential for disaster prevention.

Determination of water content of a residual soil slope in response to infiltrating rainwater using transient seepage model and its verification [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2021
Reduction of soil shear strength is significant in evaluating slope failure for rainfall-induced landslide study. Increasing soil water content due to infiltrating rainwater increases pore water pressure and decreases the shear strength of soil. In this
