This volume proposes an integral approach to studying the geophysics of Earth. It is motivated by a variety of phenomena from nature with deep and direct impacts in our lives. Such events may evolve across a large range of spatial and time scales and may be observed in the ocean, the atmosphere, the volcanic surface as well as underground.The physical laws dictating the evolution of such phenomena lead to the unifying theme of this manuscript, that is, the mathematical and computational modeling of flows and waves. Consequently, the underlying models are given in terms of Partial Differential Equations (PDEs) whose solutions are approximated using numerical methods, thus providing simulations of the aforementioned phenomena, as well as the appropriate geophysical validation and interpretation.

This book presents an overview of volcanic debris avalanche deposits, which are produced by partial volcanic edifice collapse, a catastrophic natural phenomenon. It has been 40 years since the volcanic debris avalanche associated with the 1980 eruption of Mount St. Helens, and our understanding of these events has grown considerably in the interim. Drawing on these advances, the book addresses all aspects of volcanic debris avalanches. Though previously overlooked in field-based geological and volcanological studies, these deposits are now known to be associated with most volcanoes and volcanic areas around the world. The book presents state-of-the-art ideas on the triggering and emplacement mechanisms of these events, supported by field and analogue studies, as well as new simulations tools and models used to determine their physical characteristic and hazards.

Published in two volumes, this new book, Advances in Sustainable Development and Management of Environmental and Natural Resources: Economic Outlook and Opinions, addresses the varied aspect of natural resources and their management in conjunction with socioeconomic aspects. With chapters from authors from around the world, this volume features 24 chapters that cover many aspects of the sustainable utilization of management of natural resources and provides new insight into the nexus of ecology and economy and their application in various fields of science. The chapters include case studies and research from India, Africa, South America, and elsewhere. After first laying the foundation, the volume goes on to discuss sustainable development and natural resource management from an economics point of view. Chapters address myriad issues involved in natural resources and environmental management, including soil and water resources management in arid lands, resource management for agricultural purposes, contemporary global legal norms of environment and sustainable development, how emissions factor into regional economies, mitigation of the impact of climate change through sustainable practices, rainwater harvesting technology, and much more. The chapters include case studies that discuss soil, agroforestry, agriculture, wetlands, and floral diversity. The book provides a solid foundation for a realistic perspective of the role of sustainable development and management of natural resources while taking the socioeconomic impact into consideration as well. It will be a valuable resource and reference for the study of ecology, economics, sustainable development, natural resource management, and other allied fields.

This volume describes physical, formal mathematical and exterior (morpho-structural) manifestations of wave dynamics of the Earth, defining both its deep structural image, and the external shape of planet. In addition to the standard imagination about waves in the geological environment as short-term seismological and seismic effects, wave dynamics of the Earth are considered as long-time process, comparable to the geochronological scale. The book consists of a systematic description of the conformities discovered in the set of heterogeneous and different-order objects, which have space-related regularity and recurrence at the different levels of resolution of analysis of natural systems. For expert-geologist it includes the basis of the geodynamic wave-related concept which enables to add to the traditional concept of plate tectonics, as well as the methods of quantitative interpretation of measured geo-fields.

Modern petroleum and petrotechnical engineering is increasingly challenging due to the inherently scarce and decreasing number of global petroleum resources. Exploiting these resources efficiently will require researchers, scientists, engineers and other practitioners to develop innovative mathematical solutions to serve as basis for new asset development designs. Deploying these systems in numerical models is essential to the future success and efficiency of the petroleum industry.

Multiphysics modeling has been widely applied in the petroleum industry since the 1960s. The rapid development of computer technology has enabled the numerical applications of multiphysics modeling in the petroleum industry: its applications are particularly popular for the numerical simulation of drilling and completion processes. This book covers theory and numerical applications of multiphysical modeling presenting various author-developed subroutines, used to address complex pore pressure input, complex initial geo-stress field input, etc. Some innovative methods in drilling and completion developed by the authors, such as trajectory optimization and a 3-dimensional workflow for calculation of mud weight window etc, are also presented. Detailed explanations are provided for the modeling process of each application example included in the book. In addition, details of the completed numerical models data are presented as supporting material which can be downloaded from the website of the publisher. Readers can easily understand key modeling techniques with the theory of multiphysics embedded in examples of applications, and can use the data to reproduce the results presented.

While this book would be of interest to any student, academic or professional practitioner of engineering, mathematics and natural science, we believe those professionals and academics working in civil engineering, petroleum engineering and petroleum geomechanics would find the work especially relevant to their endeavors.

Because prevailing atmospheric/troposcopic conditions greatly influence radio wave propagation above 10 GHz, the unguided propagation of microwaves in the neutral atmosphere can directly impact many vital applications in science and engineering. These include transmission of intelligence, and radar and radiometric applications used to probe the atmosphere, among others.

Where most books address either one or the other, Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications melds coverage of these two subjects to help readers develop solutions to the problems they present. This reference offers a brief, elementary account of microwave propagation through the atmosphere and discusses radiometric applications in the microwave band used to characterize and model atmospheric constituents, which is also known as remote sensing.

Summarizing the latest research results in the field, as well as radiometric models and measurement methods, this book covers topics including:

• Free space propagation
• Reflection, interference, polarization, and other key aspects of electromagnetic wave propagation
• Radio refraction and its effects on propagation delay
• Methodology of estimating water vapor attenuation using radiosonde data
• Knowledge of rain structures and use of climatological patterns to estimate/measure attenuation of rain, snow, fog, and other prevalent atmospheric particles and human-made substances
• Dual/multifrequency methodology to deal with the influence of clouds on radiometric attenuation
• Deployment of microwaves to ascertain various tropospheric conditions
• Composition and characteristics of the troposphere, to help readers fully understand microwave propagation
• Derived parameters of water, free space propagation, and conditions and variable constituents such as water vapor and vapor pressure, density, and ray bending

Gravity interpretation involves inversion of data into models, but it is more. Gravity interpretation is used in a "holistic" sense going beyond "inversion". Inversion is like optimization within certain a priori assumptions, i.e., all anticipated models lie in a limited domain of the a priori errors. No source should exist outside the anticipated model volume, but that is never literally true. Interpretation goes beyond by taking "outside" possibilities into account in the widest sense. Any neglected possibility carries the danger of seriously affecting the interpretation. Gravity interpretation pertains to wider questions such as the shape of the Earth, the nature of the continental and oceanic crust, isostasy, forces and stresses, geol- ical structure, nding useful resources, climate change, etc. Interpretation is often used synonymously with modelling and inversion of observations toward models. Interpretation places the inversion results into the wider geological or economic context and into the framework of science and humanity. Models play a central role in science. They are images of phenomena of the physical world, for example, scale images or metaphors, enabling the human mind to describe observations and re- tionships by abstract mathematical means. Models served orientation and survival in a complex, partly invisible physical and social environment.

Metaharmonic Lattice Point Theory covers interrelated methods and tools of spherically oriented geomathematics and periodically reflected analytic number theory. The book establishes multi-dimensional Euler and Poisson summation formulas corresponding to elliptic operators for the adaptive determination and calculation of formulas and identities of weighted lattice point numbers, in particular the non-uniform distribution of lattice points.

The author explains how to obtain multi-dimensional generalizations of the Euler summation formula by interpreting classical Bernoulli polynomials as Green's functions and linking them to Zeta and Theta functions. To generate multi-dimensional Euler summation formulas on arbitrary lattices, the Helmholtz wave equation must be converted into an associated integral equation using Green's functions as bridging tools. After doing this, the weighted sums of functional values for a prescribed system of lattice points can be compared with the corresponding integral over the function.

Exploring special function systems of Laplace and Helmholtz equations, this book focuses on the analytic theory of numbers in Euclidean spaces based on methods and procedures of mathematical physics. It shows how these fundamental techniques are used in geomathematical research areas, including gravitation, magnetics, and geothermal.

This open access book explores the interactions between water and earthquakes, including recent concerns about induced seismicity. It further highlights that a better understanding of the response of the water system to disturbances such as earthquakes is needed to safeguard water resources, to shield underground waste repositories, and to mitigate groundwater contamination. Although the effects of earthquakes on streams and groundwater have been reported for thousands of years, this field has only blossomed into an active area of research in the last twenty years after quantitative and continuous documentation of field data became available. This volume gathers the important advances that have been made in the field over the past decade, which to date have been scattered in the form of research articles in various scientific journals.

The present book - which is the second, and significantly extended, edition of the textbook originally published by Elsevier Science - emphasizes the interdependence of mathematical formulation and physical meaning in the description of seismic phenomena. Herein, we use aspects of continuum mechanics, wave theory and ray theory to explain phenomena resulting from the propagation of seismic waves.The book is divided into three main sections: Elastic Continua, Waves and Rays and Variational Formulation of Rays. There is also a fourth part, which consists of appendices.In Elastic Continua, we use continuum mechanics to describe the material through which seismic waves propagate, and to formulate a system of equations to study the behaviour of such a material. In Waves and Rays, we use these equations to identify the types of body waves propagating in elastic continua as well as to express their velocities and displacements in terms of the properties of these continua. To solve the equations of motion in anisotropic inhomogeneous continua, we invoke the concept of a ray. In Variational Formulation of Rays, we show that, in elastic continua, a ray is tantamount to a trajectory along which a seismic signal propagates in accordance with the variational principle of stationary traveltime. Consequently, many seismic problems in elastic continua can be conveniently formulated and solved using the calculus of variations. In the Appendices, we describe two mathematical concepts that are used in the book; namely, homogeneity of a function and Legendre's transformation. This section also contains a list of symbols.

This book collects a series of review articles summarizing the outcomes of collaborative research projects on the 1999 Chi-Chi earthquake and the 2008 Wenchuan earthquake, two of the largest and most disastrous earthquakes in Asia in the last two decades. The articles cover a broad range of aspects,including these earthquakes' fundamental mechanisms, kinematics, and the geological and geophysical background of their fracture faults. Presenting comprehensive coverage, the book offers a valuable reference guide to these two devastating earthquakes.

Major influenza pandemics pose a constant threat. As evidenced by recent H5N1 avian flu and novel H1N1, influenza outbreaks can come in close succession, yet differ in their transmission and impact. With accelerated levels of commercial and population mobility, new forms of flu virus can also spread across the globe with unprecedented speed. Responding quickly and adequately to each outbreak becomes imperative on the part of governments and global public health organizations, but the difficulties of doing so are legion. One tool for pandemic planning is analysis of responses to past pandemics that provide insight into productive ways forward. This book investigates past influenza pandemics in light of today's, so as to afford critical insights into possible transmission patterns, experiences, mistakes, and interventions. It explores several pandemics over the past century, from the infamous 1918 Spanish Influenza, the avian flu epidemic of 2003, and the novel H1N1 pandemic of 2009, to lesser-known outbreaks such as the 1889-90 influenza pandemic and the Hong Kong Flu of 1968. Contributors to the volume examine cases from a wide range of disciplines, including history, sociology, epidemiology, virology, geography, and public health, identifying patterns that cut across pandemics in order to guide contemporary responses to infectious outbreaks.

This book explores practices and approaches on pre-disaster prevention and post-disaster reconstruction for vulnerable countries and areas enhancing earthquake disaster resilience. Destructive earthquakes have frequently occurred in urban or rural areas around the world, causing severe damage on human societies. Pre-earthquake prevention and post-earthquake reconstruction effect the disaster resilience building and long-term development of the affected communities and areas. In recent years, researchers from around the world have made a lot of efforts to study on the theme 'earthquake disaster prevention and reconstruction'. The chapters in this edited volume contribute to the literature of earthquake disaster research from scientific, social and institutional aspects. These interdisciplinary studies mainly focus on human and policy dimensions of earthquake disaster, such as earthquake risk mitigation, social-physical resilience building, resilience capability assessment, healthcare surge capacity, house reconstruction, the roles of schools, households, civil societies and public participation in earthquake disaster prevention and reconstruction. The authors come from several counties, including China, Bangladesh, Iran, New Zealand, Saudi Arabia, the United Kingdom, Denmark, and Indonesia, covering the cases from those countries prone to earthquakes. These nine distinctive chapters have been elaborately selected and integrated from the international, ranked, peer-reviewed journal, Environmental Hazards.

Today's risk analysis is a very challenging field, and a solid understanding of the calculations procedure associated with it is essential for anyone involved. Fires, Explosions, and Toxic Gas Dispersions: Effects Calculation and Risk Analysis provides an overview of the methods used to assess the risk of fires, explosions, and toxic gas dispersion, and then deduce the subsequent effects and consequences of these events. The authors cover various aspects of such incidents, including the probability that an accident will occur, and how to calculate leaks, heat flux, overpressure, and the concentration of toxic clouds. The book follows by describing the consequences to people (injury or death) and material damages, and it concludes with a discussion of possible causes of destruction and common circumstances that can result in accidents. Some key features of this book include: * Introduction of basic techniques of hazard identification, emphasizing "what if" and HAZOP analyses * Step-by-step procedures for the calculation of fires (i.e., pool fire, jet fire, fire ball), explosions (VCE, BLEVE), and concentration of toxic clouds (light and heavy gases) * Methods for determining probability of injuries or lethality Invaluable to professionals, researchers, and students whose work involves predicting the consequences of accidents, this book describes simple modern methods, which are a great aid for understanding the meaning of all the variables involved -- in contrast to current complicated computer packages, which produce only results. Filling the existing gap in useful literature on risk analysis, this book follows a logical structure and presents straightforward, step-by-step calculation procedures and numerous examples that will be valuable in both teaching and learning the content.
