Implementation of spatial SV wave oblique incidence and helical pile response under this condition based on Python in finite element analysis
The traditional method of adding viscoelastic artificial boundaries and equivalent seismic loads has the disadvantages of a cumbersome adding process and a difficulty in finding errors. Therefore, this paper was based on the existing theory and derived the spatial oblique incidence equivalent node…

Comparison of synthetic unit hydrograph methods for flood assessment in a dryland, poorly gauged basin (Napostá Grande, Argentina)
This paper examined and compared the reliability of two popular unit hydrograph methods for flood assessment in a dryland, poorly gauged basin: the Soil Conservation Service (NRCS-UH) method and the geomorphologic instantaneous unit hydrograph (GIUH) model. In addition, two different estimates of…

Innovative cities as cathedrals governing sustainable-digital-energy transitions. An Introduction
This special issue, through various contributions from distinguished scholars in the field, attempts if not to provide exhaustive answers then at least to delineate the perimeter of the issues and scientifically circumscribe the contours of the questions that still exist regarding smart cities…

Neural network clustering of a set of geophysical data in comparison with the distribution of earthquake focuses in the middle basin of Lake Baikal
The high degree of earthquake clustering observed in the central part of the Baikal rift zone necessitates an investigation into the conditions conducive to such a distribution of seismic events. The crust peculiar properties, as characterized by geophysical data, affect the course of the major…

Full-scale load tests to assess the bearing capacity of peat at Zegveld
Great lengths of railway embankments are constructed on organic clay and peat layers, which are highly susceptible to significant deformations under train loading. The growing demand for transportation necessitates a re-evaluation of the stability of railway embankments constructed on peat. Current…

Highway construction at Kvithammar-Åsen, mid-Norway: Geotechnical characterization of very sensitive clay deposits
The properties of vast, sensitive clay deposits have been investigated for the construction of the E6 Kvithammar-Åsen highway, north of Trondheim, in mid-Norway. Highway construction included the design of up to 14 m thick road embankments, made possible by stabilization works using lime-cement and…

Ice content dependence of fluctuating basal forces in rock–ice avalanche: From numerical rotating drum tests
In this study, we investigated ice content effects on basal force fluctuations in rock-ice avalanches using discrete element method (DEM) rotating drum simulations. Calibrated DEM parameters reproduced experimental benchmarks, enabling numerical tests across ice contents (0–100%). Our results…

Coastal dynamics and risk assessment in the Gambia
West African coasts are experiencing a significant retreat on average, albeit highly variable according to sections. Shoreline changes were analyzed in ten sections along the Gambian coast between 2011 and 2023. The results indicated a predominant retreat, ranging from 1.27 to 4.51 m per year, with…

Geotechnical characterization and strain-rate dependent response of peat from the Netherlands
For construction and maintenance of infrastructure, a good understanding of the engineering properties of the subsoil is needed. In some areas, the subsoil contains deposits of peats and organic soils. Although many studies on the strength of peats, in the laboratory and the field, have been…

Comparing seismic piezocone and seismic dilatometer test results for the characterization of a coastal silt deposit from Finland
This paper focused on the performance comparison of in situ testing methods for geotechnical characterization of a silt deposit at Haistila, in western Finland, in the vicinity of the coastal city of Pori. Soil conditions comprise a homogeneous, up to 9 m thick, slightly overconsolidated silt…

Numerical investigation of the diversion length for the capillary barrier system
The capillary barrier system (CBS) is commonly used to control rainwater infiltration into the slope soil and enhance slope stability under rainfall conditions. In the CBS, a fine-grained layer is commonly overlayered on top of the coarse-grained layer. Because the hydraulic conductivity of…

Regional surface temperature changes in China caused by reduced air pollution and halogenated greenhouse gases
China's vast territory across a large latitude makes it an ideal country to investigate the mechanisms causing regional climate changes. Here, we showed that the temporal patterns in regional surface temperature are very different between low- and high latitude regions and between lightly and…

Permeability of coarse silts using dissipation tests in cone penetration test: Case study, Finninmäki testing site
Dissipation tests were performed at the Finninmäki testing site, Tampere, Finland, through the cone penetration test (CPTu). In these tests, both contractive and dilative behaviors were observed. The parameter $ t_{50} $, the time when 50$ \% $ of initial pore pressure, $ u_2 $, dissipates, was…

Effects of geomagnetic storms on cathodic protection systems in gas pipelines: A case study of disturbances in Argentina (2013-2018)
Gas pipelines are susceptible to telluric currents induced by temporal variations in the geomagnetic field (GMF), which are primarily driven by solar activity. These variations can generate electric fields at the Earth's surface, causing current flow through conductive infrastructure such as…
