This book draws together a series of studies of spit geomorphology and temporal evolution from around the world. The volume offers some unique insights into how these landforms are examined scientifically and how we as humans impact them, offering a global perspective on spit genesis and evolution. Spits are unique natural environments whose evolution is linked to the adjacent coast and near shore morphology, sediment supply, coastal dynamics and sea-level change. Over the past century, Global Mean Sea Level (GMSL) has risen by 10 to 20 centimetres and many coastal spits represent the first sentinel against coastal submersion. Scientific research indicates that sea levels worldwide have been rising at a rate of 3.5 millimetres per year since the early 1990s, roughly twice the average speed of the preceding 80 years. This trend, linked to global warming will undoubtedly cause major changes in spit morphology. Spits are highly mobile coastal landforms that respond rapidly to environmental change. They therefore represent a signature of past environmental change and provide a landform indicator of climate change.
This is the first comprehensive volume on cave sediments. It provides case-studies from around the world, gives guidance on appropriate applications of techniques, and their limitations, synthesizes methods that can be used to decipher complex deposits, and includes chemical deposits (speleothems) as well as clastic sediments. This book is for any geoscience researcher or student with interests in climate change, paleohydrology, karst geology, and sedimentology.
Supply of sufficient clean drinking water is often taken for granted, but it requires a considerable technical and financial effort to ensure reliable and economic water supply. This volume presents an up-to-date overview of water supply management and aims at efficient management of water supply schemes rather than design of new works. Various chapters of the book are devoted to water demands, management of reservoirs and conjunctive use of alternative sources. Asset management and loss control are also considered. Water quality and provision of water to developing communities are also discussed. Water supply management is of concern to developed urban environments as well as developing communities. The book will be equally valuable to the practising water engineer and the newcomer or graduate student in the subject.

Soil degradation, a decline in soil quality due to anthropogenic perturbations, is a serious threat with negative impacts on agriculture and the environment. The assessment and monitoring of all forms of degradation is essential to the evaluation of negative trends and implementation of mitigating technologies. Soil Degradation in the United States: Extent, Severity, and Trends is an assessment of current trends and geographic hot spots. It not only describes the types of soil degradation, but also evaluates the processes and triggers that cause the damage.
This book is the first of its kind on environmental change research devoted to monsoon-arid environment evolution history and its mechanism involved. Capturing the most prominent features of Asian climate and environmental changes, it gives a comprehensive review of the Asian Monsoon records providing evidence for spatial and temporal climatic and environmental changes across the Asian continent since the Late Cenozoic. The dynamics underlying these changes are explored based on various bio-geological records and in particular based on the evidence of loess, speleothems as well as on mammal fossils. The Asian monsoon-arid climate system which quantifies the controlling mechanisms of climate change and the way it operates in different time scales is described. Attempts to differentiate between natural change and human-induced effects, which will help guide policies and countermeasures designed to support sustainable development on the Chinese Loess Plateau and the arid west.
With climate change and deforestation, debris flows and debris avalanches have become the most significant landslide hazards in many countries. In recent years there have been numerous debris flow avalanches in Southern Europe, South America and the Indian Subcontinent, resulting in major catastrophes and large loss of life. This is therefore a major high-profile problem for the world's governments and for the engineers and scientists concerned. Matthias Jakob and Oldrich Hungr are ideally suited to edit this book. Matthias Jakob has worked on debris flow for over a decade and has had numerous papers published on the topic, as well as working as a consultant on debris flow for municipal and provincial governments. Oldrich Hungr has worked on site investigations on debris flow, avalanches and rockfall, with emphasis on slope stability analysis and evaluation of risks to roads in built-up areas. He has also developed mathematical models for landslide dynamic analysis. They have invited world-renowned experts to joint them in this book.
This book appears a century after the discovery of radioactivity. It was in 1896, when Henri Becquerel reported his first results about the penetrating radiation, which could darken the packed photographic plates. The initial fascination of radioactivity, e.g., the discovery of new radioactive elements, the first real description of the structure of atoms and their nuclei, the applications of radiotracers, the high sensitivity of activation analysis, etc., was followed by the use of atomic bomb in 1945. The mushroom cloud became a symbol of destructive nuclear power. And even nuclear energy production (which provides about 20% of the world's electricity) is overshadowed by radioactive waste. However, the latest results suggest that the Accelerator-Driven Transmutation Technology (ADTT) will solve this problem, since this technique can decrease the lifetime of the fission products comparatively to the human lifespan. Practical control of fusion may also be possible in the first decades of the next millennium.
This book presents the most relevant articles selected from the annals of the symposium. In the last few years, Brazilian Geomorphology has experienced a series of epistemological and methodological innovations expressed by the incorporation of the complexity paradigm, by the progressive break with the climate paradigm, by the emergency role of new theories, and by the advances in methodological fields favored by the adherence to geochronological techniques and in function of the increasingly widespread use of geotechnologies. Furthermore, the Anthropocene/Technogene emerge claims to be more than only a temporal cuts, but as conceptions of a science engaged with social and environmental issues. The National Symposium of Geomorphology, in the maturity of its 13th edition, constitutes a portrait and an important sample of Brazilian geomorphological production, aggregating works carried out in the most diverse types of landscapes of Brazil. The book provides an overview of the current scientific production of Brazilian Geomorphology, highlighting the diversity of landscapes and geoheritage in Brazil, the complexity of the morphogenetic and morphodynamic processes responsible for shaping its surface, and the various abundant methodologies used in geomorphological studies in tropical areas.
An exploration of the relationship between river behaviour and environmental change. The research involves a wide range of disciplines including geomorphology, geophysics, archaeology, palaeoecology, engineering and planning.
Delivering a synthesis of almost one hundred and fifty years of
research into the Jordan Rift Valley, this genuinely comprehensive
text presents a model explaining the tectonic evolution of this
part of the Syrian-African Rift Valley, which may affect opinions
regarding the geotectonic pattern of the entire western Levant.
Greenhouse-induced climate warming increasingly appears to be a reality, and the warming climate will be accompanied by an accelerated sea level rise - as much as 60-100 cm over the next century. What is commonly absent in the discussion of rising sea level, however, is the role played by the subsidence of low-lying coastal areas, which can have a far greater local effect than the eustatic rise of the sea. The combined sea-level rise and land subsidence will almost certainly make the greatest impact on coastal societies in the densely populated regions of southern Asia, but its effects will be felt globally. This volume explores the concepts of sea-level rise and coastal subsidence, both natural and anthropogenically accelerated, in the form of a series of case studies in such diverse locations as Bangkok, Bangladesh, Venice, and the Niger and Mississippi deltas, as well as a discussion of the economic, engineering and policy responses that must be considered if the effects of local sea-level rise are to be mitigated.
This volume describes mountains from all over the world, with an emphasis on mountain landforms, but also looks at their rocks, structure and age. This leads to a deduction on the mechanism which formed them, causing the authors to reject the pre-conceived and well known hypothesis that plate tectonics and folding creates mountains. The book approaches mountains from facts about mountain landscapes rather than theory. It illustrates that almost everywhere, mountains arose by vertical uplift of a former plain, and by a mixture of cracking and warping by earth movements, and erosion by rivers and glaciers, the present mountainous landscapes were created. It also gives evidence that this uplift only occured in the last few million years, a time scale which does not fit the plate tectonics theory. Another part of the evidence, shows that mountain uplift correlates very well with climatic change. Mountain building could have been responsible for the onset of the ice age. It certainly resulted in the creation of new environments.
This book presents the study of limnogeomorphology, in which past proxy data such as lacustrine sediments with information on landform development can be linked to modern observed data acquired by instruments, including hydro-geomorphological and sedimentary data. Traditionally, in the field of earth sciences, it has been thought that geophysical studies dealing mainly with the present process were not smoothly linked to geological studies that originated from historical studies. Although such earth-surface process studies are closely related to those on historical landform development in the field of geomorphology, they have been studied separately. Those two geomorphology studies correspond to process geomorphology (dynamic geomorphology) and historical geomorphology. There have been some attempts to combine them; however, they lacked past quantitative records available for further analyses. In the study of limnogeomorphology, proxy data can be converted to quantitative information to be utilized in future environmental discussions. This book also covers information not only on large lake-catchment systems, but on small systems. Those include long-term and short-term and large-scale and small-scale environmental changes in east Eurasia such as Lake Baikal, Lake Khuvsgul, Lake Biwa, and small lakes in Japan, Mongolia, China, and Korea.
Short Blurb (350 characters): Sand dunes are common aeolian landforms and are found on over ~40% of the Earth’s land surface. Distribution and characteristics of sand dunes in the northern hemisphere are the major focus. Standard Blurb (700 characters): Sand dunes are common aeolian landforms and are found on over ~40% of the Earth’s land surface. Distribution and characteristics of sand dunes in the northern hemisphere are the major focus. Practical advice on how to deal with migrating dunes and a description of proven practices are presented. The application of recently available high-resolution satellite data for mapping and change detection and a summary of advances in techniques for characterizing the mineralogy of sand is explained. The target audience of this book will be those working in the fields of arid land studies, geoinformatics, social sciences, and landscape ecology. Key Features: • Present a synthesis of past work, 'connect the dots' so that the work of physical geographers, geomorphologists, physicists and climatologists, hydrologists, and related fields can be made available within one book. • Exhaustively reviews the key recent research on the typology, distribution, formation and current status of sand dunes • Provides a synoptic overview of the current problems and prospects for controlling migrating sand dunes that threaten infrastructure, and encroaches on agricultural land and urban areas. • Demonstrates the utility of new advanced monitoring techniques such as high-resolution satellite imagery and specialized laboratory equipment to study the mineralogy and structure of dune sands
This book presents an integrated approach to the study of the evolution of the Archean lithosphere, biosphere and atmosphere, and as such it is a unique contribution to our understanding of the early Earth and life. The structural and geochemical make-up of both the oceanic and continental crust of the Archean Earth is documented in some case studies of various cratons, and the implications of the Phanerozoic plate and plume tectonic processes for the Archean geology are discussed in several chapters in the book. All chapters are process-oriented and data-rich, and reflect the most recent knowledge and information on the Archean Earth. The interdisciplinary approach of examining the evolution of the Archean crust, oceans, and life that we adopt in this book sets it apart from previous publications on Precambrian geology. The book will be attractive to researchers in academia and in industry, and to senior undergraduate students, graduate students and faculty in earth and natural sciences.
This monograph deals with the part of the field of experimental rock deformation that is dominated by the phenomena of brittle fracture on one scale or another. Thus a distinction has been drawn between the fields of brittle and ductile behaviour in rock, corresponding more or less to a distinction between the phenomena of fracture and flow. The last chapter deals with the transition between the two fields. In this new edition an attempt has been made to take into account new developments of the last two and a half decades. To assist in this project, the original author greatly appre- ates being joined by the second author. The scope of the monograph is limited to the mechanical properties of rock viewed as a material on the laboratory scale. Thus, the topic and approach is of a "materials science" kind rather than of a "structures" kind. We are dealing with only one part of the wider field of rock mechanics, a field which also includes structural or boundary value problems, for example, those of the stability of slopes, the collapse of mine openings, earthquakes, the folding of stratified rock, and the convective motion of the Earth's mantle. One topic thus excluded is the role of jointing, which it is commonly necessary to take into account in applications in engineering and mining, and pr- ably often in geology too. Shock phenomena have also not been covered.
This book addresses the origin of gold deposits to answer questions of science and curiosity. These answers contribute in turn to the improved exploration and mining of gold. Initially there is a summary of the methods used to address the genesis of gold deposits including some of the essential science and concepts. Five basic observations follow that apply to many gold deposits and need to be considered in any genetic ideas. Magmatic processes enriching gold are discussed followed by the role of aqueous fluids during gold deposit formation at elevated temperatures and pressures. Modifying effects after deposit formation include high-grade metamorphism, retrogression, weathering, and erosion. The main types of gold deposits are then explained within the spectrum of viable genetic ideas, with informal names for these examples that include gold-only, gold-plus, Carlin, slate-belt, epithermal, porphyry, iron oxide copper gold, and Archean greenstone. Case histories are included in which the role of gold geology contributed directly to discoveries-one example is at the province-scale and another at the goldfield-scale. Unlike other books on the subject, this one addresses virtually all gold deposit types rather than focusing on one type in isolation. The primary readership includes industry geologists, senior undergraduates, postgraduates, and those with some knowledge of science and an interest in the gold industry.
The 25 papers collected together in this volume present comprehensive coverage of all major aspects of landslide risk assessment, including the risk assessment framework, and methods for estimating probability of landsliding vulnerability and risk.
The study of ice composition represents an effective tool in our understanding of the dynamics of glaciers, ice sheets and ice shelves. The authors of this work relate the distribution of isotopes and impurities in ice masses to ice flow, to the key zone close to the ice-substratum interface and to the mechanisms effective in the contact zone between glacier and ocean. Other material in this book is concerned with how global changes may be induced by a climatic warming due to anthropogenic activities. This monograph on glaciology, geophysics and geomorphology is intended for researchers, graduate students and teachers.
Until now no overview of the Quaternary deposits of northeastern Europe has been available. This book fills the gap. It presents the state of research on Quaternary stratigraphy and geology, with emphasis on glacial deposits, discusses the general scientific ideas and gives an overview of the methods of investigation, some of which have rarely been applied elsewhere. It has become apparent that the region covered has many environmental problems, and a proper understanding of the Quaternary deposits is a basic requirement for dealing with them. The same is true for civil engineering. In the formerly glaciated areas almost all construction sites for roads and houses will encounter glacial deposits. This volume provides an authoritative and fascinating overview for anyone planning to venture into this field. In its 53 regional chapters the book covers Finland, Estonia, Latvia, Lithuania, Russia, Ukraine, Belarus, Poland, the Czech Republic and eastern Germany. From the text it becomes clear that not all the stratigraphical schemes are yet fully compatible or comprehensible. There can be no doubt, however, that the east was subjected to very extensive ice advances during the earlier Pleistocene. Also, in contrast to western Europe, there was a significant Early Weichselian ice advance, although not as extensive as the last, Late Weichselian event. The book is illustrated by 421 figures and 74 colour plates (mostly photographs). There are 23 tables, a detailed index and a list of over 1000 references, providing a unique collection of northeastern European geoscience literature, much of which has so far escaped the attention of western scientists. The volume, composed of contributions by 60 scientists, completes the trilogy on glacial deposits of northern Europe. Together with its two companion volumes, the Glacial deposits in North-West Europe and the Glacial Deposits in Great Britain and Ireland, it represents an invaluable source of information for the geoscientist, the advanced student or the amateur. |
