Abstract: Argentinean loess has mechanical properties highly dependent on moisture content. Sand and silt particles jointed by clay bridges and precipitated salts form macropores which undergo high volume decrease when loaded or ...

Abstract: Leakages from fuel tanks and fuel transport pipelines are common occurrences that affect the environment and the geotechnical properties of geomaterials, which is of significant relevance in the case of unstable soils. In ...

Abstract: Immiscible flow governs the macroscopic behavior of aqueous and non-aqueous phase liquids inside the porous media. Ganglia generation and movement of the advancing front during fluid displacement can only be described by ...

Abstract: Immiscible displacement processes are of key importance in remediation actions of light nonaqueous phase liquid (LNAPL) contaminated soil and groundwater. LNAPLs remain trapped in soil pores after a spill or flushing process ...

Abstract: The purpose of this research is to evaluate the aptitude of two residual soils for the remediation of groundwater contaminated by arsenic (As). Batch and soil column tests were performed to evaluate removal of As from ...

Abstract: The dielectric permittivity of soils can be significantly modified by the presence of organic contaminant in the pore fluid. Thus, nondestructive techniques based on the propagation of electromagnetic waves may be used to ...

Abstract: The main objective of this paper is to explore the potential application of electromagnetic waves to evaluate the effect of contaminant removal in granular soils. Thus, various specimens of saturated silica sand were ...

Abstract: Understanding and quantifying particle–fluid interaction (PFI) is of fundamental importance for such geoenvironmental issues as polluted soil behavior, transport of organic contaminants in porous media, and the behavior ...

Abstract: The fluid-mineral interaction defines the affinity of mineral surfaces for water in the presence of oil, determines wettability, affects interparticle forces, and controls the effectiveness of soil decontamination and oil ...
