Colloid Movement in Unsaturated Porous Media: Recent Advances and Future Directions

摘要: Investigations of colloid movement through geologic materials are driven by a variety issues, including contaminant transport, soil-profile development, and subsurface migration pathogenic microorganisms. In this review, we address recent advances in understanding transport partially saturated porous media. Special emphasis is placed on features the vadose zone (i.e., presence air–water interfaces, rapid fluctuations porewater flow rates chemistry) that distinguish unsaturated media from We examine experimental studies deposition mobilization survey developments modeling mass transfer. conclude with an overview directions for future research field.
