Published: 2026-07-16
Subjects: Engineering Mechanics, Geology, Geophysics and Seismology, Geotechnical Engineering, Hydraulic Engineering, Hydrology, Physics, Soil Science
The propagation time of pressure waves in porous media carries critical information about the constitutive parameters of the medium. This study rigorously derives the mechanical relationship between the lag time of pressure wave and the hydraulic parameters of porous media based on the diffusion wave equation. The lag time is shown to be a direct functional of the hydraulic conductivity and [...]

Published: 2026-07-08
Subjects: Civil and Environmental Engineering, Engineering, Geotechnical Engineering
Rapid and reusable landslide detection from remote-sensing imagery remains challenging because practical deployment often requires cross-region transfer learning, limited local labels, and reproducible model-to-product workflows. This paper presents LSDetector, an open-source local workbench that bridges advanced landslide detection models and real-world deployment through three-stage transfer [...]
SWMMCanada: An Open-Source Service for Generating Ready-to-Run Urban Drainage Models Across Canada
Published: 2026-07-03
Subjects: Civil and Environmental Engineering, Computational Engineering, Engineering, Environmental Engineering, Geotechnical Engineering, Hydrology, Software Engineering
Urban stormwater modelling is often slowed more by data preparation than by the simulation itself, because rainfall, terrain, land cover, soil, and pipe network data usually come from different agencies, formats, projections, and data structures. This software paper presents SWMMCanada, an open source and standardized model building service that makes Canadian urban hydrological modelling easier [...]
The role of glauconite content in controlling sand crushing and compressibility
Published: 2026-06-16
Subjects: Geotechnical Engineering
Glauconite-rich sands are increasingly posing engineering challenges in offshore and nearshore developments, since their mechanical behaviour remains poorly understood owing to the extreme crushability of glauconite grains. Particle crushing in these sediments alters stiffness, compressibility, grading, particle morphology and, consequently, engineering performance. This study presents a [...]
A Fibonacci-Like Propagation Graph for Infiltration and Internal Erosion in Heterogeneous Layered Soils
Published: 2026-06-06
Subjects: Geotechnical Engineering, Hydrology, Numerical Analysis and Scientific Computing, Soil Science
Infiltration and internal erosion in heterogeneous layered soils involve coupled flow, pressure build-up, and material degradation across preferential subsurface pathways. High-fidelity Richards-type simulators are physically detailed but can be too expensive for rapid scenario screening and Monte Carlo uncertainty propagation when hydraulic parameters are poorly constrained. We introduce a [...]
A Bayesian ground-motion model for volcano-tectonic earthquakes in southwest Iceland
Published: 2026-06-04
Subjects: Civil Engineering, Geotechnical Engineering, Tectonics and Structure
Volcano-tectonic earthquakes in Iceland and other volcanic regions produce ground motions that differ systematically from those of ordinary shallow crustal tectonic earthquakes. The recent unrest on the Reykjanes Peninsula has provided an exceptional opportunity to quantify these differences, with multiple intense swarms preceding and accompanying eruptive episodes. Building on Hernández-Aguirre [...]

Subjects: Civil and Environmental Engineering, Civil Engineering, Earth Sciences, Engineering, Engineering Science and Materials, Environmental Engineering, Environmental Sciences, Geotechnical Engineering, Hydraulic Engineering, Mechanics of Materials, Mining Engineering, Other Civil and Environmental Engineering, Physical Sciences and Mathematics, Risk Analysis
In the case of water-saturated, granular deposits that are at risk of liquefaction, engineers need reliable information about the spatial extent of soil deformation in the event of liquefaction. It is not so important for them to know the exact location of the first failure. However, existing anal-yses primarily deal with the triggering of liquefaction and offer only limited information on how [...]
Liquefaction as an energetic instability of saturated granular systems – Density control and static enthalpy equilibrium
Published: 2025-12-27
Subjects: Civil and Environmental Engineering, Civil Engineering, Earth Sciences, Engineering, Environmental Engineering, Geophysics and Seismology, Geotechnical Engineering, Hydraulic Engineering, Hydrology, Materials Science and Engineering, Mining Engineering, Other Materials Science and Engineering, Physical Sciences and Mathematics, Sedimentology
Liquefaction of saturated granular materials is commonly interpreted within stress-based frameworks that rely on the existence of an intact grain skeleton. At the onset of liquefaction, however, the contact network collapses and effective stress ceases to be a meaningful state variable. This work reformulates liquefaction as an enthalpy-driven instability of the coupled grain–water system and [...]
