Book Description
Soil Structure and Fabric sets out a method of describing the structure and fabric of soils that proceeds consistently from macroscopic descriptions in the field to descriptions from standard thin sections as viewed with a light microscope. Most of the book is devoted to the description and classification of the microscopic characteristics of soils.

Book Description
Soil Structure offers a multidisciplinary approach to the study of soil structure and its relevance to wide ranging investigations in environmental sciences. Topics covered in Soil Structure include soil structure determination, soil fabric genesis and functions, strength and stress distribution, fabric changes in plastic clays, the effects of organic matter and earthworms, air slaking, and hydraulic conductivity changes. The book also discusses litter decomposition and matter transport, the characterization of pore organization, monitoring via a neutron activated tracer, various influences on growth and phosphorus supply of plants and on water uptake by plants, the effects of acidification, and much more. Improved procedures for measuring and calculating the unsaturated hydraulic conductivity of structured soils are also given.

Book Description
This Book Brings Out The Possibilities Of Generalizations Of Behaviour Of Soils And Hence Of Predicting The Required Engineering Properties Without Elaborate Testing. We Recognize That A Single Approach Cannot Be Evolved For All Soil Types And Hence The Necessity For Classifying Soils Into Different Categories And To Use Appropriate Model For Each. First Of All, Based On Mechanism Of Stress Transfer And Interaction Between The Phases, Two Obvious Classes, The Fine Grained And Coarse-Grained Soils Have Been Differentiated.The Discussions Bring Out That Because Of Identical Mode Of Stress Transfer, The Mechanical Behaviour I.E., Compressibility, Shear Strength Relations, Permeability Variations Etc. Can Be Generalized For All Fine Grained Soils, Enabling The Prediction Of Behaviour Of Such Soils With Just The Knowledge Of Certain State And Index Properties. The Sequence Of Discussion Is On The Characterization Of Specific Soil States And Prediction Of Proportion Starting From The Ideal Saturated Uncemented Soils, Both Normally And Over Consolidated, Cemented Saturated Soils And Partly Saturated Soils.In Dealing With The Behaviour Of Coarse Grained Soils, The Importance Of Microfabric And The Difficulties In Possible Generalizations Are Discussed. Perhaps The Unique Feature Of This Book Is That The Division Of The Chapters Is Based On Different Soil States, All The Mechanical Behaviours Being Discussed Under Each Soil State.The Book Will Be Of Interest To Both Academicians And Practising Engineers, Researchers And Postgraduate Students. It Would Serve As A Textbook For Undergraduate Students With Prior Knowledge Of Basic Soil Mechanics.

Book Description
Principles of Soil Physics examines the impact of the physical, mechanical, and hydrological properties and processes of soil on agricultural production, the environment, and sustainable use of natural resources. The text incorporates valuable assessment methods, graphs, problem sets, and tables from recent studies performed around the globe and offers an abundance of tables, photographs, and easy-to-follow equations in every chapter. The book discusses the consequences of soil degradation, such as erosion, inhibited root development, and poor aeration. It begins by defining soil physics, soil mechanics, textural properties, and packing arrangements . The text continues to discuss the theoretical and practical aspects of soil structure and explain the significance and measurement of bulk density, porosity, and compaction. The authors proceed to clarify soil hydrology topics including hydrologic cycle, water movement, infiltration, modeling, soil evaporation, and solute transport processes. They address the impact of soil temperature on crop growth, soil aeration, and the processes that lead to the emission of greenhouse gases. The final chapters examine the physical properties of gravelly soils and water movement in frozen, saline, and water-repellant soils. Reader-friendly and up-to-date, Principles of Soil Physics provides unparalleled coverage of issues related to soil physics, structure, hydrology, aeration, temperature, and analysis and presents practical techniques for maintaining soil quality to ultimately preserve its sustainability.

Book Description
Soil Properties and Behavior defines the structure of the soil-water system. This book provides the background of the nature of mineral particles and the existing forces between the particles in the soil system. It also examines the structure and fabric of soil, as well as their relationship with water. Furthermore, the book explores water movement and soil performance, which are related to the physics of soil-water movement and volume changes. This book illustrates the common clay minerals in soils and discusses the methods for their identification. It also reviews the theory of one-dimensional consolidation and discusses the soil structure in consolidation and compression. The book also presents the concepts of yield and failure in soils, yield criteria, and failure theories. It also focuses on granular and cohesive soil strength, including friction properties, the intrinsic friction angle, the volumetric strain, and pore-water pressure. The last part of the book discusses soil freezing and permafrost.

Book Description
Why do some contaminants remain in soils indefinitely? How much of a threat do they pose to human health or the environment? The need for effective and economic site decontamination arises daily. Geoenvironmental Engineering: Contaminated Soils, Pollutant Fate, and Mitigation discusses why soils remain contaminated, focusing on the development of the factors, properties, characteristics, and parameters of soils and individual contaminants. Subjects covered include the basic properties of soils affecting accumulation of contaminants, long-term retention of contaminants and their fate, including the development of intermediate products. The author emphasizes the factors, interactions, and mechanisms important in the bonding and partitioning process. He provides the groundwork for determining the fate of pollutants in soils and sediments and their mitigation. Geoenvironmental Engineering: Contaminated Soils, Pollutant Fate, and Mitigation focuses on why soils and sediments remain contaminated, not how they became contaminated in the first place. You will understand why specific contaminants remain in soils and sediments, how much of a threat they pose to human health and the environment, and what steps to take for mitigation. With this information you can determine the extent of the contamination of soils and sediments, how long they will remain a threat, and what methods to use for their remediation.
