This atlas illustrates the characteristics of present-day bedforms, from the shoreline to deep-sea environments, and it also includes short reviews of the main mechanisms that generate such bedforms. The atlas is aimed at the research community, in addition to students, the public at large and companies with interests in the marine environment. The book is divided into seven sections composed of a number of short chapters: 1) bedform analysis and the main physical processes, 2) bedforms in the coastal zone, 3) bedforms on prodeltas and sorted bedforms, 4) bedforms on the continental shelf, 5) bedforms and benthos, 6) bedforms in submarine canyons and 7) slope and deep-sea bedforms. This atlas offers a comprehensive, though not exhaustive, view of the diversity of bedforms and associated processes and of the morphological and temporal scales in the enclosed tideless western Mediterranean Sea.
Just five years ago, it was generally believed that the number of food insecure people in the world was on continuous decline. Unfortunately, widespread soil degradation along with resistance to recommended agronomic practices, and little attempt to restore degraded soils have conspired with significant droughts (in regions that could least tolerate them) to swell the ranks of the food insecure to over a billion people. The U.N. Millennium Development Goals' intent to halve hunger by 2015 will not be realized. Food Security and Soil Quality brings together leading experts from across the world to provide a concise and factually supported exploration of the problem at hand and the critical steps needed to reverse it. Edited by Rattan Lal, and B.A. Stewart, two of the world's most respected soil scientists, this important work - Assesses farming systems and food security in Sub-Saharan Africa, with special emphasis on land degradation Examines concerns with and approaches to soil quality management in Brazil and China Details achievable methods for improving soil quality for sustainable production Provides an insightful comparison of temporal changes in agricultural systems productivity in Punjab, India and Ohio Discusses the human dimension of the crisis including the influence of culture and spiritual beliefs Dr. Lal himself writes that despite the existence of scientific data on sustainable management of soil and water resources, problems of soil and environmental degradation have persisted and have been aggravated. And that these problems are rooted in land misuse and soil mismanagement. This book does provide policymakers and others with an understanding of the depth, complexity, and immediacy of this crisis, but more than a call to action, it also offers soil scientists working in this area with an understanding of what is being done and what needs to be done. Most importantly, this book helps us understand that the situation is not beyond remediation were we to act with great resolve and a sense of urgency. A tree's leaves may be ever so good, So may its bark, so may its wood; But unless you put the right thing to its root, It never will show much flower or fruit. - from Leaves Compared With Flowers, by Robert Frost
This book offers a compact guide to geological core analysis, covering both theoretical and practical aspects of geological studies of reservoir cores. It equips the reader with the knowledge needed to precisely and accurately analyse cores. The book begins by providing a description of a coring plan, coring, and core sampling and continues with a sample preparation for geological analysis. It then goes on to explain how the samples are named, classified and integrated in order to understand the geological properties that dictate reservoir characteristics. Subsequently, porosity and permeability data derived from routine experiments are combined to define geological rock types and reduce reservoir heterogeneity. Sequence stratigraphy is introduced for reservoir zonation. Core log preparation is also covered, allowing reservoirs to be analysed even more accurately. As the study of core samples is the only way to accurately gauge reservoir properties, this book provides a useful guide for all geologists and engineers working with subsurface samples.
Climate change poses a fundamental threat to humanity, and thus solutions for both mitigation and adaptation strategies are becoming increasingly necessary. Biochar can offer a range of environmental services, such as reclamation of degraded land, improvement of soil fertility and carbon sequestration. However, it also raises questions, regarding sustainable feedstock provision, biomass pyrolysis, and soil amendment. These questions, among various others, are addressed in this state-of-the-art compendium. Covering a broad geographical range, with regional assessments from North America, Europe, the Near East, and Southeast Asia, this interdisciplinary volume focuses on the entire biochar supply chain, from the availability and economics of biomass resources, to pyrolysis, and ultimately to the impacts on soil properties. The combination of theory with practical examples makes this a valuable book for researchers, policymakers, and graduate students alike, in fields such as soil science, sustainable development, climate change mitigation, biomass and bioenergy, forestry, and environmental engineering.
A Comprehensive review of modern stratigraphic methods. The stratigraphic record is the major repository of information about the geological history of Earth, a record stretching back for nearly 4 billion years. Stratigraphic studies fill out our planet's plate-tectonic history with the details of paleogeography, past climates, and the record of evolution, and stratigraphy is at the heart of the effort to find and exploit fossil fuel resources. Modern stratigraphic methods are now able to provide insights into past geological events and processes on time scales with unprecedented accuracy and precision, and have added much to our understanding of global tectonic and climatic processes. It has taken 200 years and a modern revolution to bring all the necessary developments together to create the modern, dynamic science that this book sets out to describe. Stratigraphy now consists of a suite of integrated concepts and methods, several of which have considerable predictive and interpretive power. The new, integrated, dynamic science that Stratigraphy has become is now inseparable from what were its component parts, including sedimentology, chronostratigraphy, and the broader aspects of basin analysis.
This book portrays the Himalayan-born River Saraswati, a legendary river that was the lifeline of a progressive and vibrant society for more than three thousand years. Written in simple language and richly illustrated, it highlights the events that resulted in the robbing of the Saraswati of its water and the end of a wonderful culture. The author weaves a geological narrative out of a mass of data generated by explorers, archaeologists, sedimentologists, geohydrologist, seismologists and remote-sensing specialists. The story explains how a great Himalayan river disappeared and how the Harappan Civilization vanished from the banks of the river Saraswati more than three and half thousand years ago in the wake of tectonic upheavals in the foothills of the Himalaya at a time when the rainfall had drastically declined. And it reveals that nowadays the Saraswati is an extraordinary wide water-less channel coursing through the vast but dry floodplain in western India.
This introductory volume to a new series on Soil Forensics gives a kaleidoscopic view of a developing forensic expertise. Forensic practitioners and academic researchers demonstrate, by their joint contributions, the extent and complexity of soil forensics. their reports exemplify the broad range of sciences and techniques applied in all stages of forensic soil examinations, from investigations at crime scenes to providing evidence that can be used in court proceedings. Moreover the necessity is depicted of co-operation as a condition for any work in soil forensics between scientists of different disciplines, but no less between scientists and law enforcers.Soils play a role in environmental crimes and liability, as trace evidence in criminal investigations and, when searching for and evaluating, buried human remains. This book shows soil forensics as practiced in this legal context, emerging and solidifying in many countries all over the world, differing in some respects because of differences in legal systems but ultimately sharing common grounds.
First published in 1953, as the second edition of a 1942 original, this book provides an accessible account regarding field drainage, targeted at those involved in the organisation and supervision of the drainage process. The text was written to draw attention 'to the fundamentals of the subject, to portray a philosophy of draining, and to deal with the factors involved and the way in which they influence events in the soil'. Numerous illustrative figures and a bibliography are included. This book will be of value to anyone with an interest in field drainage and the history of agriculture.
This book presents the first overview of the Toarcian Oceanic Anoxic Event in the southern Iberian paleomargin, in the western Tethys. The study of catastrophic events that affected the ecosystems in the past is of great interest, because it offers the possibility of establishing models that can be applied to current and future environmental changes. The book provides comprehensive information on the changes in marine ecosystems in connection with a global massive extinction, the Early Toarcian, and with the deposition of black shales, global warming and a disruption of the carbon cycle. In addition, the book describes the incidence of this event in this part of the Tethys close to the connection with the Protoatlantic, the Hispanic Corridor. Special attention is paid to sedimentological and ichnological aspects, fossil content (macroscopic and microscopic), and geochemistry. It also presents the facies changes related to fragmentation of the shelf and the evolution to hemipel agic troughs and swells in this paleomargin. Lastly, it characterizes this anoxic event in under-researched outcrops from southern Spain and compares the findings with those in well-known sections from northern and central Europe. This book offers a unique resource for all researchers interested in the Toarcian Oceanic Anoxic Event, but also in oceanic anoxic events that occurred during the Mesozoic in general, because of their similarity to recent climatic changes.

Several numerical models of dams are considered together with coupled problems in soil mechanics and foundations. It gives wide range of modelling soil in different parts of the world. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.
Earthwork projects are critical components in civil construction and often require detailed management techniques and unique solution methods to address failures. Being earth bound, earthwork is influenced by geomaterial properties at the onset of a project. Hence, an understanding of the in-situ soil properties is essential. Slope stability is a common problem facing earthwork construction, such as excavations and shored structures. Analytical methods for slope stability remain critical for researchers due to the mechanical complexity of the system. Striving for better earthwork project managements, the geotechnical engineering community continues to find improved testing techniques for determining sensitive properties of soil and rock, including stress-wave based, non-destructive testing methods. To minimize failure during earthwork construction, past case studies and data may reveal useful lessons and information to improve project management and minimize economic losses. This volume is part of the proceedings of the 1st GeoMEast International Congress and Exhibition on Sustainable Civil Infrastructures, Egypt 2017.
Clay minerals are one of the most important groups of minerals that
destroy permeability in sandstones. However, they also react with
drilling and completion fluids and induce fines migration during
hydrocarbon production. They are a very complex family of minerals
that are routinely intergrown with each other, contain a wide range
of solid solutions and form by a variety of processes under a wide
range temperatures and rock and fluid compositions. In this volume, clay minerals in sandstones are reviewed in
terms of their mineralogy and general occurrence, their stable and
radiogenic isotope geochemistry, XRD quantification, their effects
on the petrophysical properties of sandstones and their
relationships to sequence stratigraphy and palaeoclimate. The
controls on various clay minerals are addressed and a variety of
geochemical issues, including the importance of mass flux, links to
carbonate mineral diagenesis and linked clay mineral diagenesis in
interbedded mudstone-sandstone are explored. A number of case
studies are included for kaolin, illite and chlorite cements, and
the occurrence of smectite in sandstone is reviewed. Experimental
rate data for clay cements in sandstones are reviewed and there are
two model-based case studies that address the rates of growth of
kaolinite and illite. The readership of this volume will include sedimentologists and petrographers who deal with the occurrence, spatial and temporal distribution patterns and importance of clay mineral cements in sandstones, geochemists involved in unraveling the factors that control clay mineral cement formation in sandstones and petroleum geoscientists involved in predicting clay mineral distribution in sandstones. The book will also be of interest to geologists involved in palaeoclimate studies basin analysis.Latest geochemical data on clays in sandstonesProvides important information for geologists involved in basin analysis, sandstone petrology and petroleum geology If you are a member of the International Association of Sedimentologists (IAS), for purchasing details, please see: http: //www.iasnet.org/publications/details.asp?code=SP34

The conference was held in Thessaloniki, Greece, from 25 to 28 June, 2007. The papers offer a comprehensive overview of the progress achieved in soil dynamics and geotechnical earthquake engineering, examine ongoing and unresolved issues, and discuss ideas for the future.
This volume explores specific approaches that have shown to result in crop yield increases. Research on the physiological understanding of these methods has led to the development of practical applications of plant breeding approaches to genetically improve crops to achieve higher yields. Authoritative entries from crop scientists shed new light on two water-conservation traits: one that is based on an initiation of the decrease in transpiration earlier in the soil drying cycle, and the second that is based on a sensitivity of transpiration rate under high atmospheric vapor pressure deficit that results in partial stomatal closure. Both these approaches involve partial stomatal closure under well-defined situations to decrease the rate of soil water loss. Readers will be able to analyze the circumstances under which a benefit is achieved as a result of the water-limitation trait; and key discussion points in the case studies presented will help answer questions such as what species, which environments, how often will yield be benefited for various crop species? Contributions also review the genetic variation for these two traits within each crop species and the physiological basis for the expression of these traits.
Understanding Soils of Mountainous Landscapes: Sustainable Use of Soil Ecosystem Services and Management focuses on the patterns and processes of mountainous soils, including threats due to the fragile nature of mountain ecosystems, and the conservation and management of soil ecosystem services and restoration processes. The book covers a balanced approach to land and resource management, ensuring that environmentally and socio-culturally sound interventions are developed and applied in the complex geophysical, ecological, and social landscapes of the world's mountain systems. The book provides holistic understanding of mountain soils to help environmental and soil scientists gain insight and develop new problem-solving approaches. With obvious up- and downstream linkages (e.g., a large proportion of urban canters globally depend on water that originates in the mountains) as well as globalization (e.g., continental-scale impacts of air pollution and climate change on glaciers), the long-range success of conservation measures in mountain regions requires that the following discrete but interconnected interventions be pursued concurrently: (1) the protection of biodiversity and ecosystem services, (2) empowerment of mountain communities (including family farming), and (3) elaboration of more thoughtful, context-specific policy environments for sustainable mountain development.
Sedimentary basins host, among others, most of our energy and fresh-water resources: they can be regarded as large geo-reactors in which many physical and chemical processes interact. Their complexity can only be well understood in well-organized interdisciplinary co-operations. This book documents how researchers from different geo-scientific disciplines have jointly analysed the structural, thermal, and sedimentary evolution as well as fluid dynamics of a complex sedimentary basin system which has experienced a variety of activation and reactivation impulses as well as intense salt tectonics. In this book we have summarized our geological, geophysical and geochemical understanding of some of the most important processes affecting sedimentary basins in general and our view on the evolution of one of the largest, best explored and most complex continental sedimentary basins on Earth: The Central European Basin System.
This book reports an approach developed to research and apply methods of assessing patterns of processes in the landscape, and suitability of different types of vegetation to mitigate soil erosion and sediment flux. Practical guidelines on a spatially strategic approach to management of land degradation at a range of spatial scales were produced. Originally developed for the Mediterranean environment, it has much wider potential global application. It provides researchers with methods to acquire the knowledge necessary for such an approach and provides practitioners with guidance on implementation and benefits of targeted methods of soil erosion control. It includes substantial information about processes and vegetation in the Mediterranean environment and the species effectiveness in soil erosion control.
Originally published in 1929, this book contains an overview of the conditions that have controlled the distribution of various sedimentary deposits. Marr covers topics such as marine deposits and the use of fossils for purposes of correlation. This book will be of value to anyone with an interest in physical geography and the history of geology.
This is a new edition of the book previously titled Solute Movement in the Soil-Root System, and describes in detail how plant nutrients and other solutes move in the soil in response to plant uptake. It provides a basis for understanding processes in the root zone so that they can be modelled realistically in order to predict the effects of variations in natural conditions or our own practices. The new edition brings the text up-to-date, and it will be less technical.
This book incorporates original and review articles on several aspects of petroleum geosciences from Indian terrains, both onshore and offshore, and includes diverse geological (tectonic, sedimentological, organic geochemical, paleontological, stratigraphic, modelling and various others), geophysical methods and policy aspects.
This book divides Antarctica into eight ice-free regions and provides information on the soils of each region. Soils have been studied in Antarctica for nearly 100 years. Although only 0.35% (45,000 km2) of Antarctica is ice-free, its weathered, unconsolidated material qualify as “soils”. Soils of Antarctica is richly illustrated with nearly 150 images and provisional maps are provided for several key ice-free areas.
This book presents Brazil as a country of continental dimensions. Its territory has a large variety of rock types, geological structures and climates. The country has a large variety of landscapes, such as the humid plains of the Amazon River, the dry plateaus of the semi-arid region or the subtropical mountains of the southern region. On the coast, some plateaus and mountains, like the Serra do Mar Mountain range, formed a significant barrier front to access the hinterland of Brazil. On the other side of these coastal plateaus and mountains, there is a large collection of other plateaus, mountains, plains and depressions little altered by human interference. Thus, Brazil has a unique variety of different landscapes and extraordinary geomorphological sites. The book invites readers to learn more about the beautiful Brazilian landscapes, their complexity and vastness.
This book is one out of 8 IAEG XII Congress volumes and deals with river basins, which are the focus of many hydraulic engineering and hydrogeological studies worldwide. Such studies examine river systems as both a resource of the fluvial environment, and also explore river-related hazards and risks. The contributions of researchers from different disciplines focus on: surface-groundwater exchanges, stream flow, stream erosion, river morphology and management, sediment transport regimes, debris flows, evaluation of water resources, dam operation and hydropower generation, flood risks and flood control, stream pollution and water quality management. The contributions include case studies for advancing field monitoring techniques, improving modeling and assessment of rivers and studies contributing to better management plans and policies for the river environment and water resources. The Engineering Geology for Society and Territory volumes of the IAEG XII Congress held in Torino from September 15-19, 2014, analyze the dynamic role of engineering geology in our changing world and build on the four main themes of the congress: environment, processes, issues and approaches. The congress topics and subject areas of the 8 IAEG XII Congress volumes are: Climate Change and Engineering Geology. Landslide Processes. River Basins, Reservoir Sedimentation and Water Resources. Marine and Coastal Processes. Urban Geology, Sustainable Planning and Landscape Exploitation. Applied Geology for Major Engineering Projects. Education, Professional Ethics and Public Recognition of Engineering Geology. Preservation of Cultural Heritage.
The first soil survey in the Philippines was done by Mr. Clarence Dorsey, an American soil scientist in the province of Batangas in 1903. The Soils of the Philippines, however, is the first comprehensive summary of more than a century of soil-survey work in this country. It integrates the soil concepts of the reconnaissance soil-survey results, which commenced as early as 1934 and continued until the mid 1960s, with the semi-detailed soil surveys that continue to this day. The result is the first-ever genetic key for classifying Philippine soils at soil series level; thus, making it possible for any newcomers to the soil survey field to confidently produce their own soil map, at a more detailed map scale, to suit the project requirements. This book brings together discussions on soils and soil mapping units and up-to-date international techniques and technologies. It makes soils relevant to current political realities and national issues. As soil survey moves from a reductionist agricultural-development planning tool to a more holistic and integrated approach, to enable us to understand our dynamic and complex environment, The Soils of the Philippines will be the only source of authoritative and updated data on soil resources for macro-level resource management planning for decades to come. With a vanishing breed of experienced soil surveyors, not only in the Philippines but also worldwide, it may remain the only book on Philippine soils for the next hundred years or more. Since soils follow a geological and not a human time frame, the contents of this volume will stay relevant for soil surveyors even in a fast changing world. As the country leaps from an agricultural economy towards modernization and a more diversified economic base, some of the soil series in the Philippines, for example the Guadalupe series underlying the skyscrapers of Makati City, are becoming extinct as a result of urban development. Therefore, this book serves as the repository for the soils that we possess, the soils that have been lost through decades of urbanization while, at the same time, it creates a soil classification system for the soils we are yet to discover. |
