Summary: Precipitation data are crucial for water resources management, flood and drought events, but monitoring in regions with complicated geomorphology can be unreliable. Satellite precipitation data offer a supplement to ground observations but come with errors. This study presents a methodology combining satellite and ground observations for improved spatiotemporal mapping and analysis of precipitation.

Summary: Various statistical techniques have been used to analyze and interpret radiometric survey data, but limited attention has been given to geostatistical approaches. This study utilized geostatistical techniques to analyze an airborne uranium data set in the North-western part of Ogun state, revealing strong spatial autocorrelation of uranium concentration with geological composition, highlighting the value of geostatistics in analyzing and interpreting uranium concentration.

Summary: In this study, a convex linear combination of Archimedean copulas was used to estimate Cu and describe the spatial dependence structure in the Iju porphyry Cu deposit in Iran. The best Frank, Gumbel, and Clayton copula models were determined to fit with higher-order polynomials. The performance of the copula and kriging methods were compared through a split-sample cross-validation test, and the results showed that the copula method outperformed kriging in terms of accuracy and precision.

Summary: This study identified seasonal variation in the incidence of Helicoverpa armigera larvae, with peak larval incidence observed between November 26 and December 2. Variogram analysis showed moderate to strong larval aggregation in all nine sampling weeks, with an estimated average aggregation distance of 2425.48 meters in pigeonpea fields. The Voronoi diagrams illustrated spatial heterogeneity of H. armigera larvae between sampling weeks, potentially linked to food source availability.

Summary: This study focuses on extending geostatistical software to effectively cope with uncertainty in geostatistical applications. The extension includes a rich component library, pre-built interfaces and an online application. The study discusses replacing the empirical variogram with its uncertainty bound to acknowledge underlying uncertainties and allows for a probabilistic description of the variogram and its parameters. The approach enables multiple interpretations of a sample and a multi-model context for geostatistical applications.

Summary: This study analyzed diurnal-to-seasonal wind cycles and extremes in Santa Barbara County, Southern California, and found that there are variations in wind speed cycles and percentiles among different stations. Strong winds recorded at buoys were significantly correlated with land stations, but no temporal lags were found between mountain stations and buoys. Fire weather conditions were most frequent at mountain stations in certain areas, with differences in temperature and dew point distributions during extreme winds between east and west mountain stations.

Summary: Abundant natural hydrocarbon seepage in the Santa Barbara Channel, mainly methane, was captured by steel gas capture tents placed on the seabed. Platform Holly production and nearby wells had a direct effect on the seepage rate, with production reducing seepage and shutdown increasing it. The permeability of the fault pathway between the reservoir and the seep tent was calculated to be about 3 x 10(-14) m(2). A horizontal well completed high on the structural anticline resulted in the complete cessation of seepage into the tents.

Summary: Spatial distribution of copper in sediments and its toxicological potential were compared in two reservoirs. Copper concentrations were higher and more heterogenous in the reservoir where copper sulfate was applied. The sediments were classified into different categories based on sediment quality guides and enrichment factor analysis. The classification was supported by the differences in copper concentrations and distribution patterns between the two reservoirs.

Summary: Many geosciences data are imprecise due to limitations and uncertainties in the measuring process. This paper introduces an interval-valued kriging method based on random sets theory to preserve the imprecision and relatedness in data. The numerical implementation of this method on design ground snow loads in Ohio, USA, shows its applicability and advantages.

Summary: One of the major sources of soil contamination is the industries involved in petroleum and gas discovery, extraction, and use. This study analyzed and monitored soil contamination by heavy metals in the Abteymour oilfield in Iran and created a map of contamination spread in the area. The distribution of the studied elements was found to be influenced by geological conditions and human activities, including the petroleum industry and agriculture.

Summary: In confined spaces, such as living environments and workplaces, high concentrations of radon may pose a health risk. Dense indoor radon concentration maps are needed for effective risk reduction measures tailored to local conditions. An innovative method based on Gini index computation is proposed to create interpolated maps and describe the distribution of radon concentration.

Summary: Commercial shipping is the main source of low-frequency noise in the ocean, and reducing vessel speed has been shown to significantly decrease noise emissions from ships. Ships participating in speed reduction programs between 2014 and 2017 had lower noise levels compared to non-participating ships.

Summary: The paper compares the performance of two FEM approaches in reproducing the response of bare frame structures to tunneling in dry dense sand. Both approaches provide good estimates of displacements and distortions experienced by the frames provided that the soil-foundation interface and structural stiffness are correctly accounted for. The results demonstrate the important role of shear deformations and the sensitivity of frames on separate footings to horizontal ground movements.

Summary: This paper introduces a novel in situ test for the assessment of the alarm threshold during tunneling, which provides an experimental basis for a more accurate evaluation of the mechanical response of the rock-mass and correlated acoustic emissions. The test was successfully conducted during the construction of the Brenner Base Tunnel in the Brixner granite and the practical application of the proposed approach is fully described in the case history.

Summary: The paper presents a method to assess the seismic performance of rock wedges in contact with arch-dam abutments. The method considers three-dimensional failure mechanisms and forces transmitted by the structure. A case study of a dam in Italy is presented, comparing the results of maximum wedge displacements obtained with the proposed method and a limit equilibrium approach.

Summary: This paper summarizes the investigations conducted to assess potential geohazards at the archaeological site of Dadan in Saudi Arabia. The site features sandstone cliffs from the Cambro-Ordovician period that were quarried in ancient times. Landslides and erosion pose risks to visitor safety and the preservation of valuable tombs at the site. Geological surveys, geomechanical testing, and geomatic acquisitions were used to identify the primary processes affecting the cliffs, slope talus, and tombs. This information lays the foundation for future risk mitigation and site management efforts.
