Available in PDF, EPUB and Kindle. Book excerpt: A study has been conducted to identify the causes for field-measured values of hydraulic conductivity of clay liners being typically two orders of magnitude greater than laboratory-measured values. It has been found through laboratory testing on large specimens that the size and gradation of clods and clumps of clay, prior to compaction, can significantly affect the measured hydraulic conductivity.

Available in PDF, EPUB and Kindle. Book excerpt: The new social and economic era calls for integration of ecology and economy in a system of cause and effect. The central element in this shift is sustainable development. Fundamental to the achievement of sustainable development is the requirement for environmentally responsible waste management and restoration of the environment. Solutions to the complex problems confronted by waste management and environmental restoration industry are currently handled by the geoenvironmental engineering profession that needs a good background in soil biology, chemistry, mechanics, mineralogy, and physics. In recognition of this need, this book summarizes relevant aspects of various soil physics, mineralogy, and chemistry as well as the chemistry of pollutants. This treatment will provide sufficient background to students and practicing engineers to enable them to think about how to approach waste management and environmental restoration problems.

Available in PDF, EPUB and Kindle. Book excerpt: Reasonable estimates indicate that approximately a billion cubic meters of high water content soil-like wastes are produced annually worldwide, and a large portion of these are deposited hydraulically in diked impoundment areas, some of which are among the largest earth structures in the world. The major problems emanating from this disposal method are the difficulty in dewatering the wastes, their low strength and hydraulic conductivity, their high compressibility, their potential to contaminate the groundwater, the stability of the confining dikes, and the ultimate reclamation of the disturbed land. Following a brief explanation of how many of these wastes are generated, quantitative values for key engineering properties are summarized and compared for a wide variety of waste materials and some reference soils. Then, many concepts that have been applied with success will be presented together with the advantages each offers, the difficulties involved in using it, and the limitations in our knowledge. Discussed briefly will be state-of-practice developments in mathematical modeling, laboratory testing and associated interpretations, and material property formulations.

Download or read book Technical Aspects Related to the Design and Construction of Engineered Containment Barriers for Environmental Remediation written by IAEA and published by International Atomic Energy Agency. This book was released on 2023-12-15 with total page 165 pages. Available in PDF, EPUB and Kindle. Book excerpt: Containment barrier systems are among the most widely used technologies for remediating contaminated sites. Various structures have been engineered to address site-specific needs, while barrier selection depends largely on whether regulatory requirements are prescriptive, or performance based. This publication provides an introduction to the design and construction of different containment barriers for low-level radioactive waste generated from remediation activities: basal (bottom) liners, final covers, in situ vertical barriers and in situ permeable reactive barriers. Practical aspects of each structure are discussed in theoretical case studies, which allow remediation project designers, implementers and regulators to make more informed decisions about the use of these barriers.
Download or read book Fundamentals of Geoenvironmental Engineering written by Abdel-Mohsen O. Mohamed and published by Butterworth-Heinemann. This book was released on 2017-10-31 with total page 710 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fundamentals of Geoenvironmental Engineering: Understanding Soil, Water, and Pollutant Interaction and Transport examines soil-water-pollutant interaction, including physico-chemical processes that occur when soil is exposed to various contaminants. Soil characteristics relevant to remedial techniques are explored, providing foundations for the correct process selection. Built upon the authors' extensive experience in research and practice, the book updates and expands the content to include current processes and pollutants. The book discusses propagation of soil pollution and soil characteristics relevant to remedial techniques. Practicing geotechnical and environmental engineers can apply the theory and case studies in the book directly to current projects. The book first discusses the stages of economic development and their connections to the sustainability of the environment. Subsequent chapters cover waste and its management, soil systems, soil-water and soil-pollutant interactions, subsurface transport of pollutants, role of groundwater, nano-, micro- and biologic pollutants, soil characteristics that impact pollution diffusion, and potential remediation processes like mechanical, electric, magnetic, hydraulic and dielectric permittivity of soils. - Presents a clear understanding of the propagation of pollutants in soils - Identifies the physico-chemical processes in soils - Covers emerging pollutants (nano-, micro- and biologic contaminants) - Features in-depth coverage of hydraulic, electrical, magnetic and dielectric permittivity characteristics of soils and their impact on remedial technologies

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Anglès: The extremely complex nature ofthe physical properties ofunsaturated soils with three phase material such as a compacted clay containing both air and water as pare fluids, delayed considerably the development of an understanding of the behaviour of partially saturated soils. This issue plus the fact tbat soil mecbanics was first developed in northern Europe and north-east USA where the climate is cool and wet so that the unsaturated zone is nonnally where the constructions are implemented, prometed the study of fully saturated or completely dry soils. In recent times the lack of knowledge in partly saturated soils has been more pronounced as the construction activity has increased in many wanner areas, in which the soils are in this condition. And also many applications in common construction have been pointed out, like dams, embankments, road pavements, slopes ... The behaviour of unsaturated soils is not consistent with the classical laws of the soil mechanics. It has long been established that for such soils, changes in suction do not have the same effect as changes in the applied stresses, and consequently the effective stress principie is not applicable. The aim of this dissertation is to study the behaviour of a Compacted Clay Fill, as a partly saturated soil, using the compaction and dissipation tests. With this purpose severa] samples ofKSS (Kaolin Silt & Sand) prepared in the laboratory. On one side, in the dissipation apparatus sorne samples are tested subjected to different loading and unloading stages with drained and undrained boundary conditions, considering the effects of different clod sizes, the moisture content and effort applied on tbe compaction of the samples. And on the other side, in the compaction tests the effect of the clod size and the degree of saturation on the Proctor compaction curves is assessed considering a selection of soil mixtures with different water contents and two equilibration times.
