This book offers a comprehensive review of the various options for improving the performance of overhead power lines in winter conditions, taking into account both mechanical and electrical aspects. Experience within the CIGRE community reveals many strategies to protect overhead power lines from damage caused by heavy build-up of ice and snow or electrical issues such as insulator icing flashovers. The initial approach is to consider the predicted ice loads from the available databases. This is supplemented with some fundamental aspects of icing physics that affect accretion rate as well as factors in ice shedding on traditional (metal, ceramic) and novel treated surfaces. These ice physics concepts structure the ways to categorize and evaluate methods to reduce or prevent icing on conductors and ground wires or to prevent flashover of insulators. Many utilities in cold climate regions have developed and used methods and strategies to reduce ice loads using anti-icing (AI) and / or de-icing (DI) methods. In general, AI methods are used before or early during ice build-up, while DI methods are activated during and sometimes after ice build-up. The book describes and discusses some historical, operational, or potential AI / DI systems in the ice physics context. This supports a comprehensive review of AI coatings including concepts, relevant material properties, application methods, and finally test methods for characterizing the long-term performance.

This book presents an overview of the hydrometeorological and hydrological studies and assists in tackling challenges posed by climate and land use land cover changes. The Ganga River is one of the major living streams on the planet earth and very important river system in India. This holy river is a lifeline for approximately five hundred million people. In the last few decades, River Ganges has been subjected to tremendous pressures with respect to both water quantity and water quality. This situation, already one of the alarming magnitudes, has been further provoked by hydrometeorological changes resulting in droughts, floods and reduced groundwater levels and river flows in addition to the poor river health. Thus, it is imperative to assess the various complexities and possible solutions for better management of River Ganges. This book is a valuable addition to the literature and contributes to research on River Ganges which will help better planning and management of Ganga river basin. The hydrological and hydrometeorological aspects covered in this book help practitioners, researchers, policymakers and other stakeholders.

In long-term service, material aging increases the risk of damage and failure, which can be accompanied by significant economic losses and severe environmental consequences. This book presents a selection of complementary contributions written by experts operating in the wider fields of pipeline integrity; taken together, they offer a comprehensive portrait of the latest developments in this technological area.

This book develops a discursive 'equalitarian' theoretical framework for studying African mining ecosystem issues and policy interventions. The theory of 'equalitarianism' is developed as an alternative to the reductionist approach that has dominated post-colonial debates about the classical jus ad bellum requirements to empower women in development spaces. However, the classical approach narrows the debate down to "women issues," rather than the 'whole-of-society.' As a consequence of this reductionism, women continue to be devalued in the mining sector, characterized by poverty traps, power struggles, and a lack of capacity to engage in large-scale mining (LSM) activities. This book advances principles for a holistic approach, and spells out the implications for women across the mining value chain. Drawing on moral scholarship, the book poses that for women to gain access to strategic spaces in the mining sector, the drive for empowerment must be embedded within 'whole-of-society' principles. This book is of interest to scholars researching gender policy, public policy, political philosophy, conflictology, and human geography. It also offers practitioners a guide for evaluating their policy work on mainstreaming gender in the mining sector, presenting options for financing, forging partnership and planning for an inclusive economic development in Africa, and beyond.

Regionalizing Global Climate Variations: A Study of the Southeastern US Regional Climate provides a framework for understanding regional climate in light of the many assessment reports being released regularly by international organizations. The book emphasizes global climate variations to explore the concept of the regionalization of those variations. Focusing on the climate of the Southeastern United States as a lens, it provides a template for targeting regional climate change in the context of global variability. It includes coverage of weather extremes, such as tornadoes, cyclones, and drought, and approaches the subject from a holistic perspective, including atmospheric, oceanic, and land components. The Southeastern United States is a particularly relevant case study, given the fact that it is the largest quarter of the United States and has the most coastlines, often resulting in a higher number of extreme weather events. This practical approach to understanding climate at the regional/local scale makes the book a valuable resource for students and researchers in Meteorology, Climate Science, Oceanography, Environmental Science, and other applied sectors.

Are extreme weather events becoming more common? How do extreme weather events impact society? These are critical questions that must be examined as we confront the possibility that the world will experience a change in climate over the next century. Much of the research in climatology over the past decade has focused on potential changes in long- term averages of temperature, precipitation and other factors. However, it is becoming increasingly clear that changes in average values will be accompanied by changes in extreme events. Furthermore, extreme weather events will impact society to a greater extent as people around the world continue to locate in more hazard-prone areas such as coastal zones. This book represents a major step forwards in developing a comprehensive set of information about changes in extreme events by providing a review of the problems in data availability, quality and analysis that make deriving a clear picture of world-wide changes in extreme events so difficult. Audience: The book is intended for policy-makers, professionals, graduate students and others interested in learning how extreme weather events have changed, and how they impact society both now and in the future.

This book reviews the hydrogeology of karst systems, starting with the classifications from the applied point of view, and then the hydraulic parameters (porosity, permeability, and transmissivity). It also addresses the karstification process, its resulting forms, and their hydrogeological significance. Besides, the author describes possible models of karstic aquifers and their characterization. The book also explains the classical methods for analyzing hydrograms of karst springs and deepens the analysis of time series, as a preliminary phase to the mathematical simulation of karst aquifers. Finally, it introduces the hydrogeochemical characterization of karst, of the processes involved as well as the possible pollution and protection of karst aquifers. This book is intended to be of interest for professionals in hydrogeology as well as graduate and undergraduate students.

In his trademark style, Richard Mabey weaves together science, art and memoirs (including his own) to show the weather's impact on our culture and national psyche. He rambles through the myths of Golden Summers and our persistent state of denial about the winter; the Impressionists' love affair with London smog, seasonal affective disorder (SAD - do we all get it?) and the mysteries of storm migraines; herrings falling like hail in Norfolk and Saharan dust reddening south-coast cars; moonbows, dog-suns, fog-mirages and Constable's clouds; the fact that English has more words for rain than Inuit has for snow; the curious eccentricity of country clothing and the mathematical behaviour of umbrella sales.

We should never apologise for our obsession with the weather. It is one of the most profound influences on the way we live, and something we all experience in common. No wonder it's the natural subject for a greeting between total strangers: 'Turned out nice again.'

The first edition of my book "Climate and Circulation of the Tropics" was reasonably up to date to the middle of 1985. In a second printing in 1988 it was possible to complete a few literature references and to correct some misprints. However, vigorous research has taken place over the past five years in various areas of tropical climate dynamics, especially in the atmosphere-ocean mechanisms of climate anomalies, climate prediction, ocean circulation, and paleoclimates. Promising progress has also been made in the application of general circulation modelling to tropical climate problems. In the present second edition, named "Climate Dynamics of the Tropics," I have attempted to incorporate much of the recent work to late 1990. Chapters 8 and 9 have been essentially re-written, and major additions have been made to Chapters 4 and 12 in particular. I would like to acknowledge the continued support by the U.S. National Science Foundation over the past five years. B. Parthasarathy, Poona, and H. Lessmann, San Salvador, sent me updates of data series not easily accessible. I have benefitted from discussions with numerous colleagues in the United States and overseas. In the preparation of this second edition, Marilyn Wolff patiently transferred my illegible hand-written drafts onto word processor. Dierk Polzin and Dan Skemp assisted me with the creation of the page masters and the subject index and Christopher Collimore with the author index.

Mobilities Facing Hydrometeorological Extreme Events 2 covers our need to understand how the interaction of hydro-meteorological, social and development dynamics combine to bring improvement to or a worsening of both mobile and immobile exposure. The book provides a summary of the interdisciplinary work done over the past ten years. Residential mobility-the way in which the occupation of flood zones evolves over time-and its resulting immobile exposure are also at the heart of this work. In addition, the book explores how climate change and its relation to fast floods in various regions of the world, especially the Mediterranean, is creating extreme events.

Climate extremes often imply significant impacts on human and natural systems, and these extreme events are anticipated to be among the potentially most harmful consequences of a changing climate. However, while extreme event impacts are increasingly recognized, methodologies to address such impacts and the degree of our understanding and prediction capabilities vary widely among different sectors and disciplines. Moreover, traditional climate extreme indices and large-scale multi-model intercomparisons that are used for future projections of extreme events and associated impacts often fall short in capturing the full complexity of impact systems. Climate Extremes and Their Implications for Impact and Risk Assessment describes challenges, opportunities and methodologies for the analysis of the impacts of climate extremes across various sectors to support their impact and risk assessment. It thereby also facilitates cross-sectoral and cross-disciplinary discussions and exchange among climate and impact scientists. The sectors covered include agriculture, terrestrial ecosystems, human health, transport, conflict, and more broadly covering the human-environment nexus. The book concludes with an outlook on the need for more transdisciplinary work and international collaboration between scientists and practitioners to address emergent risks and extreme events towards risk reduction and strengthened societal resilience.

This book initiates multipolar climate/clime studies of the world's altitudinal and latitudinal highlands with terrestrial, experiential, and affective approaches. Framed in the environmental humanities, it is an interdisciplinary, comparative study of the mutually-embodied relations of climate, nature, culture, and place in the Himalaya, Andes, and Arctic. Innovation-driven, the book offers multipolar clime case studies through the contributors' historical findings, ethnographic documentations, and diverse conceptualizations and applications of clime, an overlooked but returning notion of place embodied with climate history, pattern, and changes. The multipolar clime case studies in the book are geared toward deeper, lively explorations and demonstrations of the translatability, interchangeability, and complementarity between the notions of clime and climate. "Multipolar" or "multipolarity" in this book connotes not only the two polar regions and the tectonically shaped highlands of the earth but also diversely debated perspectives of climate studies in the broadest sense. Contributors across the twelve chapters come from diverse fields of social and natural sciences and humanities, and geographically specialize respectively in the Himalayan, Andean, and Arctic regions. The first comparative study of climate change in altitudinal and latitudinal highlands, this will be an important read for students, academics and researchers in environmental humanities, anthropology, climate science, indigenous studies and ecology.

This book presents central problems in the design, research and maintenance of large-size mining machines for open pits, mobile earth-moving machinery, hydraulic hammers for mining and civil engineering, and screening processes for bulk materials. It brings together the insights of numerous respected academics to offer a thorough and multifaceted overview of the topic. The first few chapters of the book deal with specific problems that frequently occur in machinery for open-pit mining. They focus on the resilience of large-size mining machines, degradation of steels used for supporting structures, and modelling of large-size rotary joints, as well as the noise hazards in connection with degradation processes. The book then moves on to discuss problems arising in earth-moving machinery, such as new approaches to the assessment of operation and maintenance, dynamic loads in front-end loader booms, and synchronic transfer of power from the engine to the driven wheels. The book concludes by discussing hydraulic hammers for mining and civil engineering, and screening processes for bulk materials that combine a vibroscreen with additional feed elements. The book is primarily intended for undergraduate and graduate mechanical engineering courses, but will also be of interest to researchers and mechanical engineers.

The Earth's climate is constantly changing. Some of the changes are progressive, while others fluctuate at various time scales. The El Nino-la Nina cycle is one such fluctuation that recurs every few years and has far-reaching impacts. It generally appears at least once per decade, but this may vary with our changing climate. The exact frequency, sequence, duration and intensity of El Nino's manifestations, as well as its effects and geographic distributions, are highly variable. The El Nino-la Nina cycle is particularly challenging to study due to its many interlinked phenomena that occur in various locations around the globe. These worldwide teleconnections are precisely what makes studying El Nino-la Nina so important.
Cynthia Rosenzweig and Daniel Hillel describe the current efforts to develop and apply a global-to-regional approach to climate-risk management. They explain how atmospheric and social scientists are cooperating with agricultural practitioners in various regions around the world to determine how farmers may benefit most from new climate predictions. Specifically, the emerging ability to predict the El Nino-Southern Oscillation (ENSO) cycle offers the potential to transform agricultural planning worldwide. Biophysical scientists are only now beginning to recognize the large-scale, globally distributed impacts of ENSO on the probabilities of seasonal precipitation and temperature regimes. Meanwhile, social scientists have been researching how to disseminate forecasts more effectively within rural communities. Consequently, as the quality of climatic predictions have improved, the dissemination and presentation of forecasts have become more effective as well. Thisbook explores the growing understanding of the interconnectedness of climate predictions and productive agriculture for sustainable development, as well as methods and models used to study this relationship.

This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of natural waterways, it above all emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The first chapter explores many of the fixed base hydraulic topics that are normally neglected in traditional texts, namely the effects on motion produced by the vegetation and macroroughnesses that characterize many mountain streams. The remaining chapters are devoted entirely to hydraulics with mobile riverbeds and put particular emphasis on inhomogeneous river channels. The book's approach goes beyond classical treatments, so as to not only introduce readers to the fundamentals of mobile riverbeds, but also enable today's river engineers to successfully design and maintain natural riverbeds.
