Book Synopsis Assessment of Non-Point Source Pollution in the Vadose Zone by : Dennis L. Corwin
Download or read book Assessment of Non-Point Source Pollution in the Vadose Zone written by Dennis L. Corwin and published by American Geophysical Union. This book was released on 1999-01-26 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 108. Non-point source (NPS) pollution in the vadose zone (simply defined as the layer of soil extending from the soil surface to the groundwater table) is a global environmental problem. Characteristically, NPS pollutants are widespread and occasionally ubiquitous in extent, thus making remediation efforts difficult and complex; have the potential for maintaining a relatively long active presence in the global ecosystem; and may result in long?]term, chronic health effects in humans and other life forms. Similar to other global environmental issues, the knowledge and information required to address the problem of NPS pollutants in the vadose zone cross several technological and subdisciplinary lines: spatial statistics, geographic information systems (GIS), hydrology, soil science, and remote sensing. Cooperation between disciplines and scientific societies is essential to address the problem. Evidence of such cooperation was the jointly sponsored American Geophysical Union Chapman/Soil Science Society of America (SSSA) Outreach Conference that occurred in October 1997, entitled “Applications of GIS, Remote Sensing, Geostatistics, and Solute Transport Modeling to the Assessment of Non-Point Source Pollution in the Vadose Zone.” The objective of the conference and this book, which was developed from the conference, was to explore current multidisciplinary research for assessing NPS pollution in soil and groundwater resources.
Book Synopsis Modeling Small-scale Physical Non-equilibrium and Large-scale Preferential Fluid and Solute Transport in a Structured Soil by :
Download or read book Modeling Small-scale Physical Non-equilibrium and Large-scale Preferential Fluid and Solute Transport in a Structured Soil written by and published by . This book was released on 1994 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deviation of non-reactive solute transport from that predicted by classical convection-dispersion equations is usually attributed to physical non-equilibrium caused by small- and large-scale pore structures in porous media. Diffusion of fluid and solute into micropores or rock matrix may occur locally, while fluid and solutes can also be channeled preferentially through interconnected macropores or fractures. A multiple-pore-region (MPR) approach with local advective-diffusive mass exchange is adopted to simulate soil column tracer breakthrough and field-scale tracer releases in the Melton Branch Subsurface Transport Facility within the Oak Ridge Reservation, Tennessee. The soil column simulation indicates that both inter-region mass exchange and intra-region convection-dispersion contribute to small-scale solute transport in approximately the same order of magnitude. The field-scale study suggests that advective mass exchange has minor effect on subsurface hydrographs, and that large diffusive mass exchange may retain tracers near the source area. Comparison of modeling results and field data suggests that subsurface bedding planes on the field site may be the cause of large-scale heterogeneity and preferential mass transport.

Book Synopsis Field-scale Water and Solute Flux in Soils by : Kurt Roth
Download or read book Field-scale Water and Solute Flux in Soils written by Kurt Roth and published by Monte Verita. This book was released on 1990 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the first workshop held at Monte Verità near Ascona, Switzerland on September 24-29, 1989. The workshop was designed to survey the current understanding of water and solute transport through unsaturated soils under field conditions, and to foster research by discussing some unresolved key issues relative to transport modeling and experimentation in four "Think Tank" groups. The first part of this book consists of the reports prepared by the Think Tank groups, who discussed the following topics: modeling approaches, effective large scale properties, evaluation of filed properties, and the role preferential flow. The second part contains a selection of reviewed original contributions presented at the workshop, with topics ranging from the presentation of results from large scale experiments, to improved or new modeling approaches, and to legal or policy aspects. This book is intended for researchers in soil science, hydrology, and environmental engineering who have an interest in transport and reaction processes in the unsaturated zone. It will provide them with a representative sample of current research activities, and with a group discussion of future research directions in four important areas of water and solute transport.
Book Synopsis Conceptual Models of Flow and Transport in the Fractured Vadose Zone by : National Research Council
Download or read book Conceptual Models of Flow and Transport in the Fractured Vadose Zone written by National Research Council and published by National Academies Press. This book was released on 2001-05-21 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid flow and solute transport within the vadose zone, the unsaturated zone between the land surface and the water table, can be the cause of expanded plumes arising from localized contaminant sources. An understanding of vadose zone processes is, therefore, an essential prerequisite for cost-effective contaminant remediation efforts. In addition, because such features are potential avenues for rapid transport of chemicals from contamination sources to the water table, the presence of fractures and other channel-like openings in the vadose zone poses a particularly significant problem, Conceptual Models of Flow and Transport in the Fractured Vadose Zone is based on the work of a panel established under the auspices of the U.S. National Committee for Rock Mechanics. It emphasizes the importance of conceptual models and goes on to review the conceptual model development, testing, and refinement processes. The book examines fluid flow and transport mechanisms, noting the difficulty of modeling solute transport, and identifies geochemical and environmental tracer data as important components of the modeling process. Finally, the book recommends several areas for continued research.

Book Synopsis Subsurface Solute Transport Models and Case Histories by : Vyacheslav G. Rumynin
Download or read book Subsurface Solute Transport Models and Case Histories written by Vyacheslav G. Rumynin and published by Springer Science & Business Media. This book was released on 2011-07-21 with total page 820 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book addresses the development of the basic knowledge of the subsurface solute transfer with a particular emphasis on field data collection and analysis coupled with modeling (analytical and numerical) tool application. The relevant theoretical developments are concerned mainly with the formulation and solution of deterministic mass-transport equations for a wide range of engineering issues in groundwater quality assessment and forecasting. The book gives many computational examples and case studies drawn from the conducted field investigations. The analyzed problems are as follows: investigation and prediction of groundwater contamination by industrial contaminants and solutions (radionuclides, chloride and nitrate brine) with special focus on the effect of (a) aquifer heterogeneity, anisotropy, and dual porosity, (b) density contrast existing between industrial waste and groundwater, or in density-stratified artesian and coastal groundwater systems; (c) physicochemical interactions that play a major role in retarding (e.g. adsorption) or enhancing (e.g. interactions between dissolved species and mobile colloids) contaminant transport; prediction of the effects of pumping on groundwater quality at wellfields; groundwater dating using stable and radioactive isotopes for prediction and assessment of contamination potential; field and laboratory tests’ design and analysis, and monitoring data interpretation; partitioning of surface and subsurface flows using isotope techniques. One of the most essential topics addressed in the book is the migration and fate of radionuclides. Model development is motivated by field data analysis from a number of radioactively contaminated sites in the Russian Federation: near-surface radioactive waste disposal sites and deep-well radioactive waste injection sites. They play a unique role in the advancement of knowledge of the subsurface behavior and fate of many hazardous radionuclides and can be considered as field-scale laboratories. Thus, the book, along with theoretical findings, contains field information, which will facilitate the understanding of subsurface solute transport and the development of a methodology for practical applications to groundwater hydrology.
