The movement of groundwater is a basic part of soil mechanics. It is an important part of almost every area of civil engineering, agronomy, geology, irrigation, and reclamation. Moreover, the logical structure of its theory appeals to engineering scientists and applied mathematicians. This book aims primarily at providing the engineer with an organized and analytical approach to the solutions of seepage problems and an understanding of the design and analysis of earth structures that impound water. It can be used for advanced courses in civil, hydraulic, agricultural, and foundation engineering, and will prove useful to consulting engineers — or any public or private agency responsible for building or maintaining water storage or control systems. Among the special features of this book are its coverage of previously unavailable Russian work in the field, an extensive appendix of concepts in advanced engineering mathematics needed to deal with physical flow systems, and numerous completely worked-out and solved examples coupled with over 200 problems of varying difficulty.

The concept of effective stress and the effective stress equation is fundamental for establishing the theory of strength and the relationship of stress and strain in soil mechanics and poromechanics. However, up till now, the physical meaning of effective stress has not been explained clearly, and the theoretical basis of the effective stress equation has not been proposed. Researchers have not yet reached a common understanding of the feasibility of the concept of effective stress and effective stress equation for unsaturated soils.

M. Karamouz, A. Ahmadi, M. Akhbari ... 676 pages - Publisher: CRC Press; 1st edition (March, 2011) ... Language: English - ISBN-10: 1439837562 - ISBN-13: 978-1439837566 ... 

Increasing demand for water, higher standards of living, depletion of resources of acceptable quality, and excessive water pollution due to urban, agricultural, and industrial expansions have caused intense environmental, social, economic, and political predicaments. More frequent and severe floods and droughts have changed the ability and resiliency of water infrastructure systems to operate and provide services to the public. These concerns and issues have also changed the way we plan and manage our surface and groundwater resources. Groundwater Hydrology: Engineering, Planning, and Management presents a compilation of the state-of-the-art subjects and techniques in the education and practice of groundwater and describes them in a systematic and integrated fashion useful for undergraduate and graduate students and practitioners. The book develops a system view of groundwater fundamentals and model-making techniques through the application of science, engineering, planning, and management principles. It discusses the classical issues in groundwater hydrology and hydraulics followed by coverage of water quality issues. The authors delineate the process of analyzing data, identification, and parameter estimation; tools and model-building techniques and the conjunctive use of surface and groundwater techniques; aquifer restoration, remediation, and monitoring techniques; and analysis of risk. They touch on groundwater risk and disaster management and then explore the impact of climate change on groundwater and discuss the tools needed for analyzing future data realization and downscaling large-scale low-resolution data to local watershed and aquifer scales for impact studies. The combined coverage of engineering and planning tools and techniques as well as specific challenges for restoration and remediation of polluted aquifers sets this book apart. It also introduces basic tools and techniques for making decisions about and planning for future groundwater development activities, taking into account regional sustainability issues. An examination of the interface between groundwater challenges, the book demonstrates how to apply systems analysis techniques to groundwater engineering, planning, and management.

Frozen Ground Engineering first introduces the reader to the frozen environment and the behavior of frozen soil as an engineering material. In subsequent chapters this information is used in the analysis and design of ground support systems, foundations, and embankments. These and other topics make this book suitable for use by civil engineering students in a one-semester course on frozen ground engineering at the senior or first-year-graduate level. Students are assumed to have a working knowledge of undergraduate mechanics (statics and mechanics of materials) and geotechnical engineering (usual two-course sequence). A knowledge of basic geology would be helpful but is not essential. This book will also be useful to advanced students in other disciplines and to engineers who desire an introduction to frozen ground engineering or references to selected technical publications in the field. BACKGROUND: Frozen ground engineering has developed rapidly in the past several decades under the pressure of necessity. As practical problems involving frozen soils broadened in scope, the inadequacy of earlier methods for coping became increasingly apparent. The application of ground freezing to geotechnical projects throughout the world continues to grow as significant advances have been made in ground freezing technology. Freezing is a useful and versatile technique for temporary earth support, groundwater control in difficult soil or rock strata, and the formation of subsurface containment barriers suitable for use in groundwater remediation projects.

"Groundwater and Soil Remediation: Process Design and Cost Estimating of Proven Technologies" describes conventional treatment technologies and explains how they are designed and what they cost. This practical book provides design details and examples of remediation techniques with an emphasis on the integration of remediation technologies into a process design scheme. Chemical engineering techniques are applied to civil and environmental engineering and hydrogeologic contamination problems, allowing engineers to select the best-suited remediation solution from competing alternatives. The steps in systematic process design and process control are described in detail for a variety of soil and groundwater remediation techniques, including metals removal from groundwater, groundwater remediation using carbon absorption, stripping of groundwater, aqueous chemical oxidation, bioremediation systems, soil venting, thermal treatment for soils and sludges, soil washing, and stabilization and solidification. Applications of traditional cost estimating methods as well as those developed especially for remediation systems, based on what is often limited subsurface information, are also presented. The book provides a logical pathway for determining the best feasible combinations of processes for complex remediation systems, explains how readers can learn to interpret or create piping and instrumentation diagrams (P&IDs), and gives a comprehensive exposition for cost estimating of treatment systems with both traditional methods and computer programs.
