This book highlights the aeolian processes in the desert zone of Kazakhstan and Central Asian Deserts, and analyzes the current status of dust and sand storms in Central Asia and Kazakhstan. It also highlights the analyses, dynamics and long-term observations of storms on the basis of numerous cartographic materials and satellite images. Dust/sand storms are a common and important phenomenon in the arid and semi-arid regions of Kazakhstan and Central Asia as well,especially in its southern parts, where areas are covered by a great variety of deserts and offer a significant source of mineral and salt aerosols. The deserts of Kazakhstan mostly cover lowlands and extend from the eastern coast of the Caspian Sea to the piedmonts of the Tien-Shan Mountain. In Kazakhstan and Central Asia desertification processes due to wind erosion in the form of dust/sand storms were observed in semi-desert and desert landscapes.
This book provides recent developments and improvements in the modeling as well as application examples and is a complementary work to the previous Lecture Notes Vols. 77 and 80. It summarizes the fundamental work from scientists dealing with the development of constitutive models for soils, especially cyclic loading with special attention to the numerical implementation. In this volume the neo-hypoplasticity and the ISA (intergranular strain anisotropy) model in their extended version are presented. Furthermore, new contact elements with non-linear constitutive material laws and examples for their applications are given.Comparisons between the experimental and the numerical results show the effectiveness and the drawbacks and provide a useful and comprehensive pool for all the constitutive model developers and scientists in geotechnical engineering, who like to prove the soundness of new approaches.
This book, featuring a truly interdisciplinary approach, provides an overview of cutting-edge mathematical theories and techniques that promise to play a central role in climate science. It brings together some of the most interesting overview lectures given by the invited speakers at an important workshop held in Rome in 2013 as a part of MPE2013 ("Mathematics of Planet Earth 2013"). The aim of the workshop was to foster the interaction between climate scientists and mathematicians active in various fields linked to climate sciences, such as dynamical systems, partial differential equations, control theory, stochastic systems, and numerical analysis. Mathematics and statistics already play a central role in this area. Likewise, computer science must have a say in the efforts to simulate the Earth's environment on the unprecedented scale of petabytes. In the context of such complexity, new mathematical tools are needed to organize and simplify the approach. The growing importance of data assimilation techniques for climate modeling is amply illustrated in this volume, which also identifies important future challenges.
In addition to describing core concepts and principles, this book reveals professional methodologies and tools used by national agencies and private corporations to predict sites' potential for wind and solar power generation. Each chapter focuses on a different issue, showing readers the corresponding methodology, as well as examples of how to apply the techniques described. These techniques are explained with step-by-step guides that demonstrate how environmental variables in complex terrains can be characterized and forecasted.The authors present an adaptive finite element mass-consistent model, which computes a diagnostic wind field in the three-dimensional area of interest using observed wind data from measurement stations - data which is then interpolated using a physical model of the wind field in the boundary layer. An ensemble method is presented based on the perturbation of the numerical weather prediction models' results. The book goes on to explain solar radiation characterization and forecasting. Solar radiation and electrical power generation temporal and spatial variability are discussed and modelled. Different statistical methods are presented in order to improve solar radiation forecasting using ground measurement, numerical weather predictions (NWPs) and satellite-derived data. This book is focused on both probabilistic and point forecast explaining different models and methodologies to improve the forecasting. The results obtained from various simulations around the world are presented in tables. Finally, the book explains a possible methodology to develop a Solar Map taking into account solar radiation, terrain surface conditions and cast shadows. As such, the book provides an overview of the concepts, principles and practices involved in the treatment of environmental variables related to solar radiation or wind fields, especially when complex terrains are involved, offering useful resources for students and researchers alike. It also equips professionals with the methodologies and tools needed to construct environmental variable maps and conduct forecasting for solar radiation and wind fields.

This book presents a selection of the best papers from the HEaRT 2015 conference, held in Lisbon, Portugal, which provided a valuable forum for engineers and architects, researchers and educators to exchange views and findings concerning the technological history, construction features and seismic behavior of historical timber-framed walls in the Mediterranean countries. The topics covered are wide ranging and include historical aspects and examples of the use of timber-framed construction systems in response to earthquakes, such as the gaiola system in Portugal and the Bourbon system in southern Italy; interpretation of the response of timber-framed walls to seismic actions based on calculations and experimental tests; assessment of the effectiveness of repair and strengthening techniques, e.g., using aramid fiber wires or sheets; and modelling analyses. In addition, on the basis of case studies, a methodology is presented that is applicable to diagnosis, strengthening and improvement of seismic performance and is compatible with modern theoretical principles and conservation criteria. It is hoped that, by contributing to the knowledge of this construction technique, the book will help to promote conservation of this important component of Europe's architectural heritage.
This book describes the discovery of the stratosphere itself and of various unexpected phenomena in the stratosphere: e.g., a manned balloon flight in 1901 as high as 11 km; an expedition to Lake Victoria in Africa in 1908 which found inexplicable west winds in the stratosphere above the equator; and the discovery of the ozone layer in the 1930s, the Berlin Phenomenon in 1952, the Quasi-Biennial Oscillation in 1960, the influence of volcanic eruptions in 1970, the ozone hole in 1984, and the influence of the 11-year solar cycle in 1987. The book also describes how these phenomena are connected with each other and how they create variability in the climate system, in addition to man-made changes, such as the decrease in ozone. We use the stratosphere as one example of Nature's complexity and of how often discoveries are ignored because they do not fit prevalent concepts.
Fish die. Seagulls starve. Economies wither. And that's just in the coastal villages. El Nino--The Christ Child--and its climatological opposite, La Nina, are global events so powerful and strange they virtually have personalities. Many remember the El Nino seasons of 1982-83 and 1997-98, which brought floods, tornadoes, droughts, and snow to unusual locales. Increased study of these Tropical Pacific phenomena, also known as ENSO (the El Nino and Southern Oscillation), has now enabled scientists to predict the ENSO state as much as 12 to 18 months in advance and has helped to shape weather prediction in general. Here, the basic causes and effects of El Nino and La Nina are carefully chronicled for anyone in search of accurate and current information on these natural phenomena. Chapters are devoted to the history of ENSO; its influence on global weather and on the United States, including the ecosystem; and how governments and industries worldwide are utilizing new weather data to harness ENSO's economic impact, rather than be saddled by it. A chronology tours key events, from the 15th century diary observations of colonists in Ecuador and Peru to recent events like the devastating El Nino of 1997-98, which was responsible for 23,000 deaths and $33 billion in damages. Biographies of important researchers, illustrations and maps, and an extensive bibliography help make this a total guide to these magnificent natural cycles.
This edited volume sheds new light on the impact of rapid Land Use/Cover Changes (LU/CC) on greenhouse gases (GHG's) and aerosol emissions in South and Southeast Asia. Several countries in South/Southeast Asia have the highest population growth rates in the world, which is the main cause for LU/CC. Conversion of dense forests to agricultural areas and then to residential and urban areas is most commonly observed in South/Southeast Asian countries with a significant release of GHG's and aerosols. The book showcases several case studies on the use of remote sensing and geospatial technologies to quantify biomass burning and air pollution impacts, aerosol pollution, LU/CC, and impacts on ecosystem services. The book also includes articles on regional initiatives in research, capacity building, and training. The authors of this book are international experts in the field, and their contributions highlight significant drivers and impacts of air pollution in South/Southeast Asia. Readers will discover the latest tools and techniques, in particular, the use of satellite remote sensing and geospatial technologies for quantifying GHG's, aerosols and pollution episodes in this region.

The topics covered are highly diverse and include drainage and impact mitigation, water quality, rainfall in urban areas, urban hydrologic and hydraulic processes, tools, techniques and analysis in urban drainage modelling, modelling interactions and integrated systems, transport and sewer processes (incl. micropollutants and pathogens), and water management and climate change. The conference's primary goal is to offer a forum for promoting discussions amongst scientists and professionals on the interrelationships between the entire water cycle, environment and society.
It is now possible to determine concentrations of trace constituents and pollutants in the lower atmosphere from space, a development which heralds a new era for tropospheric chemistry. The authors describe how to develop and validate methods for determining tropospheric trace constituents from satellite data, to encourage the use of these data by atmospheric chemists, and to explore the undoubted synergism which will develop between satellite and ground-based measurements, and will eventually give rise to a permanent observation system for the troposphere. The book comprises several comprehensive overviews, prepared by acknowledged experts in the field, together with a series of individual reports from investigators whose work represents the cutting edge of the subject. A variety of results, giving global distributions of several species and their modelling are reported. Most results stem from ESA satellite data, but there is also an account of the North American work in this field which has mainly concentrated on global distributions of ozone. It is fair to say that the field, as it develops, will revolutionize the way in which atmospheric chemistry is done. This timely book provides a good introduction for anyone with an interest in the future of the troposphere.

It also describes the implemented demonstration sites of SLRB during the project course as well as lessons learnt on efficient project management and the dissemination of knowledge and technologies.
Every night, above our heads, a drama of epic proportions is playing out. Diamond planets, zombie stars, black holes heavier than a billion Suns. The cast of characters is extraordinary, and each one has its own incredible story to tell. We once thought of our Earth as unique, but we have now discovered thousands of alien planets, and that's barely a fraction of the worlds that are out there. And there are more stars in the Universe than grains of sand on every planet in the Solar System. But amid all this vastness, the Milky Way Galaxy, our Sun and the Earth are home to the only known life in the Universe - at least for now. With a foreword from Professor Brian Cox, and access to all the latest stunning NASA photography, Andrew Cohen takes readers on a voyage of discovery, via the probes and telescopes exploring the outer reaches of our galaxy, revealing how it was formed and how it will inevitably be destroyed by the enigmatic black hole at its heart. And beyond our galaxy, the expanding Universe, which holds clues to the biggest mystery of all - how did it all begin? We now know more about those first moments of existence than we ever thought possible, and hidden in this story of how it all began are the clues to the fate of the Universe itself and everything in it.
The key to the solution of geological hazards such as Karst water inrush and mud burst in tunnel lies in the accurate prediction or detection of Karst and groundwater. By means of on-site monitoring, theoretical analysis and indoor simulation experiments, the authors conduct in-depth research on the characteristics of water-bearing media and their mechanism of action, and explored the relevance of "Karst morphology", "Karst groundwater" and "fractal characteristics". An evaluation model of Karst development degree based on hydrochemical kinetic parameters and fractal index of Karst morphology is established. Based on the combination of Karst groundwater dynamics, hydrochemistry, water-rock interaction theory and fractal theory, the hydrochemical Kinetics and fractal index evaluation technique for Karst development is proposed. It provides a new theory and method for improving the accuracy of Karst and groundwater forecasting. The research results are of practical and guiding significance to the construction, Karst geological disasters prevention and management of various underground projects in Karst areas. Engineers and technicians, hydrogeological engineering geologists, and college students engaged in tunnel and underground engineering will find it valuable.

Many questions, exercises and solutions are given. Researchers and engineers in the field of Geotechnical Engineering and Anti-seismic Engineering can benefit from it.
Before the drought of the early twenty-first century, the dry benchmark in the American plains was the Dust Bowl of the 1930s. But in this eye-opening work, Kevin Z. Sweeney reveals that the Dust Bowl was only one cycle in a series of droughts on the U.S. southern plains. Reinterpreting our nation's nineteenth-century history through paleoclimatological data and firsthand accounts of four dry periods in the 1800s, Prelude to the Dust Bowl demonstrates the dramatic and little-known role drought played in settlement, migration, and war on the plains. Stephen H. Long's famed military expedition coincided with the drought of the 1820s, which prompted Long to label the southern plains a ""Great American Desert"" - a destination many Anglo-Americans thought ideal for removing Southeastern Indian tribes to in the 1830s. The second dry trend, from 1854 to 1865, drove bison herds northeastward, fomenting tribal warfare, and deprived Civil War armies in Indian Territory of vital commissary. In the late 1880s and mid-1890s, two more periods of drought triggered massive outmigration from the southern plains as well as appeals from farmers and congressmen for federal famine relief, pleas quickly denied by President Grover Cleveland. Sweeney's interpretation of familiar events through the lens of drought lays the groundwork for understanding why the U.S. government's reaction to the Dust Bowl of the 1930s was such a radical departure from previous federal responses. Prelude to the Dust Bowl provides new insights into pivotal moments in the settlement of the southern plains and stands as a timely reminder that drought, as part of a natural climatic cycle, will continue to figure in the unfolding history of this region.

This book mainly studies the methodologies of structural design and construction for highway engineering, which are applicable to the overall control and the precise operation of engineering structures. It explores the method of comprehensive analysis, the simplification of complex problems, and the application of typical engineering tools. In turn, the book presents a number of innovative approaches, e.g. the coordinated control of structural deformation method, the theory of underground engineering balance and stability, and the soft soil foundation treatment of "bumping at the bridgehead." These methodologies are then illustrated in typical cases and representative problems, explained from a practical standpoint. Examples in special settings are also discussed, e.g. highway construction in Tibet, and rebuilding after the Wenchuan earthquake. The book offers a valuable reference guide for all those whose work involves highway engineering design, construction, management, and scientific research.
This book describes the second phase of the Qinghai-Tibetan railway construction project and is the first technological book discussing the geological routing of the Qinghai-Tibetan railway project on the "roof of the world." Based on practical experience of railway construction work, it provides a substantial number of examples with detailed descriptions and conclusions. The complex geological environment of the Qinghai-Tibetan railway as well as the selection and optimization of the route are illustrated vividly and clearly with quotes, figures, photos, and tables. Connecting Golmud and Lhasa, it has a total length of 1142 km and at the Tanggula Pass has an altitude of 5072m-higher than any other in the world. A 960 km section is on a plateau at altitudes above 4000 m, and 550 km are in the permafrost region, making it the world's longest and highest railway in the permafrost plateau region. The book is a model for the integration of theory and practice, making it a valuable reference source for civil engineering professionals working in geological routing in permafrost plateau regions, active fault zones, meizoseismal areas, nature reserves, and regions with geohazards such as steep slopes, sand and snow drifts and geothermal hazards. |
