Laterite Soil Engineering is one of a few books about solving engineering problems with the help of engineering pedology. This book presents the latest information on the laterite soils' geotechnical characteristics and engineering behavior. It shows that laterite soils are different from natural soils and that most laterite soils can be evaluated for engineering purposes using accepted theories and well-known test procedures for temperate-zone soils. This book also shows that modern concepts based on pedological considerations are very useful and take a logical approach to the identification and evaluation of laterite soils for engineering purposes. The first four chapters focus on reviewing information about the processes of tropical weathering and laterization. Chapter five summarizes information about the location, morphology and composition of laterite soils. Chapter six highlights the geotechnical implications of the pedogenic processes of tropical weathering, and it emphasizes the contribution of the results of these pedogenic processes to the deviations of engineering behavior of the problem of laterite soils. In addition, chapter seven discusses the influence of laterite soil genesis on the physic-chemical characteristics based on comparing the properties of three genetic soil groups formed under three different weathering conditions. Chapters eight through nineteen discuss the geotechnical characteristics and evaluation of laterite soils, and the effects of pedogenesis and soil-forming factors on the geotechnical and stabilization characteristics of laterite soils. The last chapter discusses the little information that exists on the application of laterite soils in engineering problems.

This Brief analyses and discusses the laterites in the Bengal Basin. The book highlights: (1) the definition, identification and classification of ferruginous materials, (2) the mode of laterite formation and its other horizons, (3) processes and theories of lateritisation, (4) determination of laterite ages, (5) recognition of palaeogeomorphic and palaeoclimatic significance and (6) geo-chronology and reconstruction of former lateritized landscapes. The chapters cover the tectono-climatic evolution of north-south laterite profiles of the north-western Bengal Basin on the Rajmahal Basalt Traps, Archean Granite-Gneiss, Gondwana Sandstones, Palaeogene Gravels and Older Palaeo-Deltaic Alluvium. The book uses advanced field-based studies, quantitative analysis and thematic mapping to cover various areas of palaeogeography and regolith geology of the Bengal Basin in connection with laterite genesis, palaeoweathering, tectonic geomorphology, Quaternary geomorphology and pedogeomorphology. It introduces laterites as a potential stratigraphic marker in Indian geology by explaining their palaeogeomorphic and palaeoclimatic significance. This Brief is a comprehensive resource to researchers, students and academicians of geography, geomorphology and geology working on laterites.

In comparison with engineering, geology is a relatively new domain of know ledge. Man has been building almost from the moment he came down out of the trees or emerged from the caves. All of his structures were founded in or upon rock or soil. Before the end of what we call ancient history, he had learned a great deal about materials, mechanics, and structures. This empirical information had become an organized field of practical knowledge by the time of Leonardo da Vinci. Although both foundations and ma terials of construction were largely earthy, codified knowledge of neither one nor the other existed at that time. During the last two centuries, geology has emerged and has recently begun to take on a more quantitative aspect. A generation ago, it joined hands with civil engineering to create soil mechanics. Engineers began to apply the science of geology to foundations and materials with astoundingly successful results, and geologists began to acquire an understanding of engineering methods, applying what they could to their problems. Geologi cal engineering was born of this union. People of an older time employed stone and brick in construction, although cut brick and sawed stone were used more sparingly because of a scarcity in both suitable raw materials and techniques. They were used in Cambodia, for example. A material able to meet requirements was found nearby, known as itica culla. In India it was called vettu culla, but F. A.

The soil water retention curve, the saturated hydraulic conductivity and the unsaturated hydraulic conductivity function are basic soil hydraulic functions and parameters. Ample apprehension of the soil hydraulic functions and parameters is required for a successful formulation of the principles leading to sustainable soil management, agricultural production and environmental protection. From these, all the other parameters, required in the solution of the practical tasks, are derived. The basic soil hydraulic functions are strongly dependent upon the soil porous system. The development of models is characteristic by the gradual transition from the simplest concepts up to the sophisticated approaches, which should correspond to the visual reality studied by soil micromorphology. 2 Soil Porous System and Soil Micromorphometry 2.1 An Overview on the Quantification of the Soil Porous System Quanti? cation of the soil porous system consists of classi? cation of soil pores, ch- acterization of the soil pores shapes and the estimation of the pore size distribution function. When the hydraulic functions of the soil pores are considered, the following laws of hydrostatics and hydrodynamics are applied as best ? tting to the classi? cation criteria of the size of the pores (Kutilek and Nielsen 1994, p. 20, Kutilek 2004): A. Submicroscopic pores that are so small that they preclude clusters of water molecules from forming ? uid particles or continuous water ? ow paths.
