This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: Indiscriminate land disposal of hazardous chemicals and industrial wastes, in the due course of time, causes contamination of the ground water regime as well as the subsurface soil layers. Various complex geo-chemical processes and mechanisms control the transport of these contaminants when they come in contact with the soil-water system.The transport of contaminants is often predicted with the help of mathematical models dealing with a set of governing equations, which are solved using either analytical or numerical methods. However, input parameters for these models can be obtained by conducting either controlled field experiments or laboratory column tests. To overcome the limitations associated with the laboratory and field scale experiments, geotechnical centrifuge modelling has been adopted by researchers and engineers. This book highlights such a research program conducted using a geotechnical centrifuge, and the instrumentation and the testing methodology adopted for monitoring contaminant transport through geotechnical centrifuge models. Also, it features, Finite Element modelling to valid the centrifuge test results. It may be a useful guide to an aspiring researcher.

This book was released on 2005-12-28 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: These proceedings document the various papers delivered and partially presented at the International Conference “From experimental evidence towards numerical modeling of unsaturated soils,” which was held in Weimar (Germany) during 18-19 September 2003. The conference was organized under the auspices of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) and the National German G- technical Society (DGGT). The need to understand the behavior of unsaturated soils is becoming exclusively - sential for the geotechnical engineers and designers. In the last three decades many - searchers have made significant contribution to the understanding of the unsaturated soil mechanics. Nevertheless, application of the subject to variety of new problems still - quires our attention. This International conference is a mere attempt to unite researchers and engineers in geotechnical engineering and to discuss about the problems associated with the unsaturated soils. Doing so the objectives of these lecture notes are as follows: - to promote unsaturated soil mechanics for practical application, - to exchange experiences in experimental unsaturated soil mechanics and numerical modeling, - to discuss application of unsaturated soil mechanics to variety of problems. In other words, we could also name these two volumes as “From theory to daily pr- tice”. I would like to extend my deep sense of appreciation as the editor and the Head of the organizing committee, to many persons who have contributed either directly or indirectly to organize the International conference and to finalize these proceedings.

Available in PDF, EPUB and Kindle. Book excerpt: During the last four decades, tremendous advances have been made towards the understanding of transport characteristics of contaminants in soils, solutes, and tracers in geological media. Transport & Fate of Chemicals in Soils: Principles & Applications offers a comprehensive treatment of the subject complete with supporting examples of mathematical models that describe contaminants reactivity and transport in soils and aquifers. This approach makes it a practical guide for designing experiments and collecting data that focus on characterizing retention as well as release kinetic reactions in soils and contaminant transport experiments in the laboratory, greenhouse), and in the field. The book provides the basic framework of the principals governing the sorption and transport of chemicalsin soils. It focuses on physical processes such as fractured media, multiregion, multiple porosities, and heterogeneity and effect of scale as well as chemical processes such as nonlinear kinetics, release and desorption hysteresis, multisite and multireaction reactions, and competitive-type reactions. The coverage also includes details of sorption behavior of chemicals with soil matrix surfaces as well the integration of sorption characteristics with mechanisms that govern solute transport in soils. The discussions of applications of the principles of sorption and transport are not restricted to contaminants, but also include nitrogen, phosphorus, and trace elements including essential micronutrients, heavy metals, military explosives, pesticides, and radionuclides. Written in a very clear and easy-to-follow language by a pioneer in soil science, this book details the basic framework of the physical and chemical processes governing the transport of contaminants, trace elements, and heavy metals in soils. Highly practical, it includes laboratory methods, examples, and empirical formulations. The approach taken by the author gives you not only the fundamentals of understanding of reactive chemicals retention and their transport in soils and aquifers, but practical guidance you can put to immediate use in designing experiments and collecting data.

This book was released on 2022-01-21 with total page 861 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rise of rapid and uncontrolled industrialization, its alarming levels of hazardous waste produced, and their negative contribution to the international environmental epidemic of global warming — in addition to the decrease in room to dispose of these wastes safely — have put the pressure for many engineers, researchers, and key decision-makers to find the answers to the constant tussle between progress and sustainability — and quickly.Environmental Geotechnology revisits existing concepts of geotechnical engineering critically, and brings them up to date with new knowledge and current affairs so as to better address and serve today's needs of the professionals. It points out the role and importance of the parameters and mechanisms that govern the interaction of contaminants with geomaterials (soil and rock mass), and also discusses their degradation in the long-run, and the consequences that follow.The book starts from a engineering philosophy that incorporates the influence of environmental effects (both manmade and natural) on geotechnical engineering practices. Its contents are based on geotechnical and environmental engineering studies pertaining to waste management, such as: the safe handling, transportation and disposal of waste, the estimation of waste leakage into the subsurface, its consequences, methods of containment, and the development of schemes to remediate contaminated land. It also proposes innovative strategies for waste management through the utilization of wastes based on a comprehensive characterization.Modelling techniques such as accelerated physical modelling using geotechnical centrifuge, finite-element or difference-based numerical modelling and physico-chemico-mineralogical modelling are discussed in this book to enable the study of the complex (and otherwise slow) process of contaminant-geomaterial interaction.Related Link(s)
