Summary: This study compared different spatial interpolation algorithms for rainfall data in New Zealand, showing that kriging was the most effective method for spatial interpolation, outperforming inverse distance weighting. Based on RMSE values, kriging with external drift performed best in April, while ordinary cokriging was the most accurate interpolator for the other 11 months. Results indicated that ordinary cokriging was identified as the best method for interpolating rainfall distribution in New Zealand for almost all months.

Summary: In a semi-arid region of Maadher, central Hodna (Algeria), groundwater quality is significantly affected by anthropogenic activities and climate change's effects. This study uses water quality indices and GIS techniques to evaluate the groundwater quality and identify contaminated wells. The results show that the groundwater is of poor quality with high concentrations of nitrate ions, calcium, chlorine, and sulfate. The spatial distribution of different elements varies depending on the direction of groundwater flow. The groundwater saturation index helps determine the origin of mineralization and chemical processes in the aquifer.

Summary: This paper proposes a feature-preserving interpolation method for digital elevation models (DEMs) by integrating a structure tensor into the radial basis function to ensure anisotropy, which demonstrates more accurate results compared to classical interpolation methods. The proposed method outperforms traditional interpolation methods in terms of accuracy, visually appealing surfaces, and a good balance between retaining terrain features and removing noise.

Summary: This study used GIS-based geostatistics and multivariate analysis to estimate the spatial variability of soil physico-chemical characteristics in Sultan Batheri Block, Wayanad district. A total of 32 soil samples were collected and analyzed using standard analytical techniques. The results showed high variation in soil organic carbon and low variation in electrical conductivity. Principal component analysis and correlation coefficient matrix analysis revealed the interrelationships among soil properties. Spatial distribution of soil characteristics was developed using inverse distance weighting and kriging methods, which exhibited high accuracy according to cross-validation tests. The levels of nitrogen and phosphorus in the study area were found to be ideal, indicating no contamination risk.

Summary: The study found a primary dependence of interpolation accuracy on soil sampling density, with ordinary kriging (OK) and inverse distance weighted (IDW) methods achieving similar interpolation accuracy regardless of soil chemical properties and sampling density. This study enables efficient soil sampling for farmers and may also be useful for professions dependent on field sampling such as biology, geology, and mining.

Summary: Two integration frameworks, GDA and GRA, combined with two interpolation techniques, OK and IDW, were used to merge satellite precipitation with ground-based observations. The merged precipitation products based on GDA-OK showed significant improvements compared to the original TMPA. However, the GRA-based merged precipitation products had systematic underestimations and were not recommended for satellite-gauge precipitation merging over the large spatial scale of Chinese mainland.

Summary: Site productivity indices have been widely used to describe age-normalized height and volume of forest species. In this study, a variety of modeling methods were used to predict Site Index and 300 Index for Pinus radiata D. Don, with non-parametric models like eXtreme Gradient Boosting and random forest outperforming parametric and geospatial models. The use of regression kriging improved prediction accuracy, especially for parametric models, and an ensemble model combining predictions from random forest, XGBoost, and regression model provided the most precise predictions for both Site Index and 300 Index.

This study investigates the time-dependent response of thin spray-on liner (TSL) specimens, cured over 500 days, under constant stress levels. Correlations between the results were used to predict the material's service life. A Burgers creep model was also developed, and a generic equation was obtained to describe the liner's nonlinear time-dependent behavior.
