TL;DR: In this article, a total of 62 groundwater samples has been collected and analyzed in laboratory for major cations and anions, and principal component analysis (PCA) yielded principal components explaining 79.9% of the variance in the dataset, which indicated ion exchange, soil mineralization, dissolution of carbonates and halite are the major processes governing the groundwater geochemistry.

TL;DR: Urea coated by modified-starch was double coated by a geopolymer to enhance the controlled release characteristics that produced promising results with respect to the longevity of nitrogen release from the final product.

TL;DR: In this article, the authors focus on different water-quality variables, for groundwater quality evaluation and aquifer vulnerability assessment due to pollutants/contaminants present in groundwater, and describe the different groundwater quality problems related to toxicities of the fluoride, nitrate and heavy metals and radionuclides in Saudi Arabia.

TL;DR: In this paper, two statistical methods are used in the modeling, i.e., traditional ordinary least squares (OLS) regression and geographically weighted regression (GWR), to evaluate the NDVI-rainfall relationship.

TL;DR: In this paper, a transient numerical model has been developed using the segregated solution approach to study the performance of packed and coated finned tubes in adsorber beds for desalination and cooling applications.
