All undergraduate and postgraduate students of science and engineering faculties will be benefited by this book. It is meant for all undergraduate and postgraduate students of civil engineering science faculty and geology irrespective of their specializations. This book is based mainly on a course of lectures prepared to cover the syllabus of engineering geology course in Universities all over the country. The book will be useful for Civil Engineering students of other universities also. The engineering geology portion of the book also covers the engineering geology included in the B.Sc, M. Sc and M. Tech courses in geology and the book will meet the requirements of students of geology as far as engineering geology is concerned like practicing engineers who need a simple introduction to the principles of geology which are important from the point of view of engineering will get them in this book."

A complete introductory text on an increasingly popular subject, "Geology and Environment in Britain and Ireland" aims to provide suitably broad coverage for students requiring a treatment clearly focused on familiar examples but retaining a global perspective. The book summarizes for Earth and environmental scientists the ways in which geology relates to the natural environment and to the human activities that it supports.;The natural environment is more than the oceans, the atmosphere and the diversity of the land surface. It extends below the ground and stretches back in time through the Earth's history. These environmental dimensions are the concern of geology. First, the book summarizes the geological influences on society through control of landscape and human geography, and through the threats posed by hazards such as landslides, subsidence and earthquakes.;Next the many Earth resources that support human activity are described: land, water, construction materials, minerals, coal, oil and gas. How are they formed or replenished? Which resources are sustainable for use over more than the immediate geological future? Thirdly, the impacts of human activity on the Earth are exam

The development of constitutive relations for geotechnical materials, with the help of numerical models, have increased notably the ability to predict and to interpret the mechanical behaviour of geotechnical works. This work covers rock excavations, soil excavations, earth fills and dams.

A thorough knowledge of geology is essential in the design and construction of infrastructures for transport, buildings and mining operations; while an understanding of geology is also crucial for those working in urban, territorial and environmental planning and in the prevention and mitigation of geohazards.

Geological Engineering provides an interpretation of the geological setting, integrating geological conditions into engineering design and construction, and provides engineering solutions that take into account both ground conditions and environment.

This textbook, extensively illustrated with working examples and a wealth of graphics, covers the subject area of geological engineering in four sections:

Fundamentals: soil mechanics, rock mechanics and hydrogeology

Methods: site investigations, rock mass characterization and engineering geological mapping

Applications: foundations, slope stability, tunnelling, dams and reservoirs and earth works

Geohazards: landslides, other mass movements, earthquake hazards and prevention and mitigation of geological hazards

As well as being a textbook for graduate and postgraduate students and academics, Geological Engineering serves as a basic reference for practicing engineering geologists and geological and geotechnical engineers, as well as civil and mining engineers dealing with design and construction of foundations, earth works and excavations for infrastructures, buildings, and mining operations.

A CD-ROM accompanies this handbook of practical techniques for interpreting geological structures at map scale from surface to subsurface maps. The CD-ROM has color graphs and models, and the book includes new material, in particular examples of 3-D models and techniques for using kinematic models to predict fault and ramp-anticline geometry. The book is geared toward the professional user concerned about the accuracy of an interpretation and the speed with which it can be obtained from incomplete data. Numerous analytical solutions are given that can be easily implemented with a pocket calculator or a spreadsheet.

A profound meditation on climate change and the Anthropocene and an urgent search for the fossils-industrial, chemical, geological-that humans are leaving behind A Times Book of the Year * A Daily Telegraph Book of the Year What will the world look like ten thousand or ten million years from now? In Footprints, David Farrier explores what traces we will leave for the very deep future. From long-lived materials like plastic and nuclear waste, to the 50 million kilometres of roads spanning the planet, in modern times we have created numerous objects and landscapes with the potential to endure through deep time. Our carbon could linger in the atmosphere for 100,000 years, and the remains of our cities will still exist millions of years from now as a layer in the rock. These future fossils have the potential to tell remarkable stories about how we lived in the twenty-first century. Through literature, art, and science, Footprints invites us to think about how we will be remembered in the myths, stories, and languages of our distant descendants. Travelling from the Baltic Sea to the Great Barrier Reef, and from an ice core laboratory in Tasmania to Shanghai, one of the world's biggest cities, David Farrier tells a story of a world that is changing rapidly, and with long-term consequences. Footprints will not only alter how you think about the future, it will change how you see the world today.

The Azores archipelago consists of nine islands that emerge from the Azores Plateau in the Central Northern Atlantic, situated within the triple junction of the American, Eurasian and African lithosphere plates. Subaerial volcanic activity has been well known since the Pliocene and continues today, with several well-documented eruptions since the settlement of the islands in the fifteenth century. The origin of the Azores Plateau has been a matter of scientific debate and thus this book provides the first comprehensive overview of geological features in the Azores from volcanological, geochemical, petrological, paleontological, structural and hydrological perspectives
