This thesis focuses on the seismic response of piles in liquefiable ground. It describes the design of a three-dimensional, unified plasticity model for large post-liquefaction shear deformation of sand, formulated and implemented for parallel computing. It also presents a three-dimensional, dynamic finite element analysis method for piles in liquefiable ground, developed on the basis of this model,. Employing a combination of case analysis, centrifuge shaking table experiments and numerical simulations using the proposed methods, it demonstrates the seismic response patterns of single piles in liquefiable ground. These include basic force-resistance mode, kinematic and inertial interaction coupling mechanism and major influence factors. It also discusses a beam on the nonlinear Winkler foundation (BNWF) solution and a modified neutral plane solution developed and validated using centrifuge experiments for piles in consolidating and reconsolidating ground. Lastly, it studies axial pile force and settlement during post-earthquake reconsolidation, showing pile axial force to be irrelevant in the reconsolidation process, while settlement is process dependent.

This book summarizes unique research findings on the hydrodynamic behavior of ice particles (ice crystals, snow, graupel and hailstones) in the atmosphere. The fall behavior of ice hydrometeors determines how and how fast a mixed-phase cloud can grow or dissipate. The book discusses how the authors used computational fluid dynamics (CFD) methods and numerical simulations to determine these behaviors, and presents these computations along with numerous detailed tables and illustrations of turbulent flow fields. It also examines the implications of the results for the general atmospheric sciences as well as for climate science (since the cloud problem is the source of the greatest uncertainty in model-based climate predictions). As such it allows readers to gain a clear and comprehensive understanding of how particles fall in clouds and offers insights into cloud physics and dynamics and their impact on the climate..

* a source book for the latest findings on climate change

This book demystifies the models we use to simulate present and future climates, allowing readers to better understand how to use climate model results. In order to predict the future trajectory of the Earth's climate, climate-system simulation models are necessary. When and how do we trust climate model predictions? The book offers a framework for answering this question. It provides readers with a basic primer on climate and climate change, and offers non-technical explanations for how climate models are constructed, why they are uncertain, and what level of confidence we should place in them. It presents current results and the key uncertainties concerning them. Uncertainty is not a weakness but understanding uncertainty is a strength and a key part of using any model, including climate models. Case studies of how climate model output has been used and how it might be used in the future are provided. The ultimate goal of this book is to promote a better understanding of the structure and uncertainties of climate models among users, including scientists, engineers and policymakers.

The weather affects everyone at sea, whether you are pottering along the coast, motoring from port to port or sailing to another continent. This book explains the basic principles that govern the weather from a practical, on the water, sailor's point of view. It goes through global, regional and then local weather patterns so you understand what is happening, how this might change and why. Armed with this knowledge and understanding you will be more confident to make decisions about when and when not to venture out to sea and what to expect if things change while you are out there. Simon Rowell shares his experience as a round-the world skipper and world-class weather forecaster. He explains the basic physics creatively and puts it in context with real situations to enable you to apply weather theory to practical sailing scenarios. Hundreds of illustrations aid the communication of what can be a complex subject, enabling you to better understand the weather and increase your enjoyment and safety when out on the water. This book is part of Fernhurst Books' Skipper's Library series of practical books for the cruising sailor.

The Earth's magnetosphere is part of our environment, and physical processes in the magnetosphere and coupling between the solar energy stream, the solar wind, and the magnetosphere are important to our understanding of our environment. Variations in the electromagnetic and particle energy output of the Sun have a significant effect on global changes. The energy transfer mechanisms at the dayside magnetospheric boundary layers and their ionospheric signatures may be even more important to solar-terrestrial research than the nightside processes. The dayside boundary layer and the polar cusps are the Earth's windows to outer space.

This book describes thoroughly the North American Climate of the past 65 million years, with special emphasis on the last 21,000 years, as revealed by paleoclimatic observations and climate models. It analyzes weather observations over the past century and satellite measurements of the last few decades to develop a picture of more recent climatic trends. It explains how global climate models are used to simulate and project climate, and presents the application of these models to reproduce recent climate variations and predict future North American climate. It answers the critical question of whether observed climate change is due to natural variations or human activity.

In 1998, my colleague, Forrest Mims, and I began a project to develop inexpensive handheld atmosphere monitoring instruments for the GLOBE Program, an international environmental science and education program that began its operations on Earth Day, 1995. GLOBE's goal was to involve students, teachers, and scientists around the world in authentic partn- ships in which scientists would develop instrumentation and experimental protocols suitable for student use. In return, data collected by students and their teachers would be used by scientists in their research. This kind of collaboration represented a grand vision for science education which had never before been attempted on such a scale, and we embraced this vision with great enthusiasm. Between 1998 and 2006, Forrest Mims and I collaborated on the development of several instruments based on Mims' original concept of using light emitting diodes as spectrally selective detectors of sunlight, which was first published in the peer-reviewed literature in 1992. These instruments have evolved into a set of tools and procedures for monitoring the transmission of sunlight through the atmosphere, and they can be used to learn a great deal about the composition of the atmosphere and the dynamics of the Earth/atmosphere/sun system. If measurements with these instruments are made properly, they have significant scientific value, as well.

This is the first book dedicated to the developing knowledge on how the world's largest ice sheet formed and changed over its 34 million years history. In explaining the story of Antartica, information on terrestrial and marine geology, sedimentology, glacier geophysics (including airborne reconnaissance), shipborne geophysics, and numerical ice sheet and climate modelling, will be interwoven within eleven chapters, each deling with an important historical theme. The approach will be to first 'set the scene', involving chapters dedicated to how ice sheets and their glacial history can be measured. This opening section will provide information necessary to comprehend the latter section of the book, in which five chapters will related the glacial and climate evolution of Antartica during the most important time-frames in which changes have occurred.

Global Change studies are increasingly being considered a vital source of information to understand the Earth Environment, in particular in the framework of human-induced climate change and land use transformation. Satellite Earth Observing systems provide a unique tool to monitor those changes. While the range of applications and innovative techniques is constantly increasing, this book provides a summary of key case studies where satellite data offer critical information to understand the causes and effects of those environmental changes, minimizing their negative impacts. This book will be of interest to researchers and practitioners in the field of remote sensing, geographical information, meteorology and environmental sciences. Also scientists and graduate up to post-graduate level students in environmental science will find valuable information in this book.

Climate and other environmental changes are drawing unprecedented concern and attention from national governments, international organizations and local communities. Global warming has left noticeable impacts on the environment and the ecosystems it supports (including humans), and has important implications for sustainable economic and social development in the future. Satellite observations of climate and environmental change have become an increasingly important tool in recent years in helping to shape the response of international communities to this critical global challenge. The book presents the latest advances in satellite-based remote sensing of the Earth's environment - ranging from applications in climate and atmospheric science to hydrology, oceanography, hydrology, geomorphology, ecology and fire studies. Introductory chapters also cover key technical aspects such as instrumentation, calibration, data analysis, and GIS tools for decision-making.

Covering an area of over 130 million km2 spanning the Mediterranean, equator and tropics, the African continent features a spectacular geographic diversity. Consequently, it is characterised by extremely variable climatic, edaphic and ecological conditions, associated with a wide range of natural vegetation and wildlife, as well as human population density, crops and livestock.

In this book, Henry Le Houerou presents his bioclimatic and biogeographic classification of Africa. The extensive data provide the basis for comparisons between various African regions, and with regions on other continents such as Latin America or the Indian subcontinent. The results constitute a rational basis for national, regional and sub-regional rural development planning, and for agricultural research dealing with aspects such as plant and animal introductions, the extrapolation or interpolation of experimental or developmental findings, and ecosystems dynamics. Possible problems of applications are also examined."

This book deals with the main principles of large-scale atmospheric dynamics on the basis of adiabatic motion constants. It can be considered as an introduction to the theory of quasi two-dimensional fluid motion concentrating primarily on nearly horizontal fluid parcel displacements in a stably stratified compressible fluid. A thorough mathematical treatment of the governing equations is coupled with a clear interpretation of the phenomena studied and accompanied by examples of real meteorological data analysis. Topics include a complete set of compressible fluid dynamic equations along with a survey on fluid dynamical conservation laws used in meteorology and atmospheric physics; the derivation of two-dimensional atmospheric models; large-scale flows; isentropic analysis of large-scale atmospheric processes; and the principles of kinetic energy sinks and their relation to the energy balance in the atmosphere.

This book explains the engineering required to bring geothermal resources into use. The book covers specifically engineering aspects that are unique to geothermal engineering, such as measurements in wells and their interpretation, transport of near-boiling water through long pipelines, turbines driven by fluids other than steam, and project economics. The explanations are reinforced by drawing comparisons with other energy industries.

A vast amount has been written on climate change and what should be our response. Rise and Fall of the Carbon Civilisation suggests that most of this literature takes a far too optimistic position regarding the potential for conventional mitigation solutions to achieve the deep cuts in greenhouse gases necessary in the limited time frame we have available. In addition, global environmental problems, as exemplified by climate change, and global resource problems - such as fossil fuel depletion or fresh water scarcity - have largely been seen as separate issues. Further, proposals for solution of these problems often focus at the national level, when the problems are global. The authors argue that the various challenges the planet faces are both serious and interconnected. Rise and Fall of the Carbon Civilisation takes a global perspective in its treatment of various solutions: * renewable energy; * nuclear energy; * energy efficiency; * carbon sequestration; and * geo-engineering. It also addresses the possibility that realistic solutions cannot be achieved until the fundamentally ethical question of global equity - both across nations today and also inter-generational - is fully addressed. Such an approach will also involve reorienting the global economy away from an emphasis on growth and toward the direct satisfaction of basic human needs for all the Earth's people. Rise and Fall of the Carbon Civilisation is aimed at the many members of the public with an awareness of climate change, but who wish to find out more about how we need to respond to the challenge. It will also be of interest to technical professionals, as well as postgraduate students and researchers, from the environmental and engineering science sectors.
