Book Description
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.

Book Description
As the pressure to conserve agricultural land and green-field sites has grown it has become increasingly important to reclaim land that has been damaged by past industrial usage, e.g. areas of mining subsidence, tailings dams and lagoons. Furthermore the need to conserve primary aggregates is providing an impetus for re-use of waste materials in engineered construction.This book is the proceedings of the GREEN3, the third in a four-yearly series of international symposia that discuss aspects of geotechnical engineering intimately related to the environment.

Book Description
This book gathers selected papers presented at the 8th International Congress on Environmental Geotechnics (ICEG), held on October 28 - November 1, 2018 in Hangzhou, China. The theme of the congress is “Towards a Sustainable Geoenvironment”, which means meeting the needs of the present generation without compromising the ability of future generations to meet their own needs. Under this theme, the congress covers a broad range of topics and provides an excellent opportunity for academics, engineers, scientists, government officials, regulators, and planners to present, discuss and exchange notes on the latest advances and developments in the research and application of environmental geotechnics.

Book Description
Two intrusive in-situ measurement systems, the C-CORE Shear Wave Profiling System and the Oxford University Densimeter, were used to carry out in-situ profiles of bulk density and shear wave velocity in contaminated dredge spoils. The spoils have high water content and, at the time of the survey, exhibited densities in the range of 1160 kg/m 3 to 1302 kg/m 3 and undrained shear strengths in the range of zero to 2.7 kPa, in the uppermost 3.85 metres of the deposit. The objective of using the above technologies was to provide a profile of in-situ small strain shear stiffness of the deposit through the combination of the bulk density and shear wave velocity measurements.

Peat and organic soils commonly occur as extremely soft, wet, unconsolidated surficial deposits that are an integral part of wetland systems. These types of soils can give rise to geotechnical problems in the area of sampling, settlement, stability, in situ testing, stabilisation and construction.

Book Description
Effective measurement of the composition and properties of petroleum is essential for its exploration, production, and refining; however, new technologies and methodologies are not adequately documented in much of the current literature. Analytical Methods in Petroleum Upstream Applications explores advances in the analytical methods and instrumentation that allow more accurate determination of the components, classes of compounds, properties, and features of petroleum and its fractions. Recognized experts explore a host of topics, including: A petroleum molecular composition continuity model as a context for other analytical measurements A modern modular sampling system for use in the lab or the process area to collect and control samples for subsequent analysis The importance of oil-in-water measurements and monitoring The chemical and physical properties of heavy oils, their fractions, and products from their upgrading Analytical measurements using gas chromatography and nuclear magnetic resonance (NMR) applications Asphaltene and heavy ends analysis Chemometrics and modeling approaches for understanding petroleum composition and properties to improve upstream, midstream, and downstream operations Due to the renaissance of gas and oil production in North America, interest has grown in analytical methods for a wide range of applications. The understanding provided in this text is designed to help chemists, geologists, and chemical and petroleum engineers make more accurate estimates of the crude value to specific refinery configurations, providing insight into optimum development and extraction schemes.

Book Description
Peat and organic soils commonly occur as extremely soft, wet, unconsolidated surficial deposits that are an integral part of wetland systems. These types of soils can give rise to geotechnical problems in the area of sampling, settlement, stability, in situ testing, stabilisation and construction. There is therefore a tendency to either avoid building on these soils, or, when this is not possible, to simply remove or replace soils, which in some instances can lead to possibly uneconomical design and construction alternatives. However, in many countries of the world, these soils cover a substantial land area and pressure on land use is resulting in ever more frequent utilisation of such marginal grounds. For the successful design, construction and performance of structures on such marginal soils, it is crucial to predict geotechnical behaviour in terms of settlement, shear strength and stability, with respect to time. This means expanding our knowledge base and calls for a reliable characterisation of their geotechnical properties and mechanical behaviour and subsequently, the devising of suitable design parameters and construction techniques for dealing with these materials. A sound scientific understanding of the nature and functions of peat and organic soils is critical to their correct and safe use, and this book contributes by offering students, researchers, engineers and academics involved with these types of soils a comprehensive overview. This book will be useful not only to those in the field of geotechnical engineering, but also to soil scientists and agriculturalists, who are involved in the development of peatlands.
