The sea has been the site of radical changes in human lives and national histories. It has been an agent of colonial oppression but also of indigenous resistance, a site of loss, dispersal and enforced migration but also of new forms of solidarity and affective kinship. "Sea Changes "re-evaluates the view that history happens mainly on dry land and makes the case for a creative reinterpretation of the role of the sea: not merely as a passage from one country to the next, but a historical site deserving close study.
This issue contains 16 papers, presenting work on tsunami hazards, earthquakes, and related computational infrastructure. The integration of multihazard simulations and remotely sensed observations is providing enormous benefits to earthquake and tsunami research. Earthquakes cause damage, but also generate tsunamis, which create additional damage. Remotely sensed observations coupled with geologic field measurements and simulations contribute to our understanding of earthquake processes, which is necessary for mitigating loss of life and property from these damaging events. This book focuses on assimilation of remotely sensed observations to advance multihazards simulation. This capability provides a powerful virtual laboratory to probe earthquake behavior and the earthquake cycle. Hence, it offers a new opportunity to gain understanding of the earthquake nucleation process, precursory phenomena, and space-time seismicity patterns needed for breakthrough advances in earthquake forecasting and hazard quantification.
This volume presents a reconstruction of the formation of the environmental conditions and biota in the present-day Baltic Sea area during the last glacial cycle and thereafter under the influence of extra-terrestrial, climatic and geological factors. Abiotic conditions in the contemporary Baltic Sea (water salinity, temperature, oxygen and light conditions, currents and other water movements) are characterized and in this background the natural regional system of the sea has been generated. Important issues are considered such as life forms in the Baltic and their dependence on the natural environment (both in the conditions of the relative stable environment and during the regime shifts), as well as anthropogenic influences and the basic differences between the areas of the World Ocean and the brackish Baltic Sea. This book also equips readers with basic principles of assessments and management of ecosystems and fish resources (including the long-term assessment and forecast on ecosystems and fish resources) and provides information on the structures of international collaboration developed in the Baltic Sea.
This book introduces a framework of tsunami modelling from generation to propagation, aimed at application to the new observation started in Japan after the devastating tsunami of the 2011 Tohoku-Oki earthquake. About 150 seismic and tsunami sensors were deployed in a wide region off the Pacific coast of eastern Japan in order to catch tsunami generation inside the focal area, which makes a clear departure from conventional observations that detect tsunamis far from the source region. In order to exploit the full potential of this new observation system, it is not enough to model tsunami generation simply by static sea-bottom deformation caused by an earthquake. This book explains dynamic tsunami generation and sea-bottom deformation by kinematic earthquake faulting, in which seismic and acoustic waves are also included in addition to static sea-bottom deformation. It then systematically derives basic tsunami equations from the fundamental equations of motions. The author also illustrates the details of numerical schemes and their applications to tsunami records, making sound linkages among these topics to naturally understand how a tsunami is physically or mathematically described. This book will be a comprehensive guide for graduate students and young researchers to start their research activities smoothly.
This book focuses on the metallogeny and main tectonic events of the North China Craton from early Precambrian to Phanerozoic. It covers the Archean crustal growth, Paleoproterozoic rifting-subduction-collision processes, Great Oxidation Event, Meso-Neoproterozoic multiple rifting, Phanerozoic reworking of the North China Craton, as well as metallogeny related to above different processes. The North China Craton is one of the oldest cratons in the world. It has experienced a complex geological evolution since the early Precambrian, and carries important records of secular changes in tectonics and metallogeny. It provides a systematic review and new results on the growth and evolution of the North China Craton and metallogeny. It will be of broad interest to the earth scientists working in the fields of economic geology, geochemistry, and tectonics of the North China Craton and eastern Asian.
Modelling forms an implicit part of all engineering design but many engineers engage in modelling without consciously considering the nature, validity and consequences of the supporting assumptions. Derived from courses given to postgraduate and final year undergraduate MEng students, this book presents some of the models that form a part of the typical undergraduate geotechnical curriculum and describes some of the aspects of soil behaviour which contribute to the challenge of geotechnical modelling. Assuming a familiarity with basic soil mechanics and traditional methods of geotechnical design, this book is a valuable tool for students of geotechnical and structural and civil engineering as well as also being useful to practising engineers involved in the specification of numerical or physical geotechnical modelling.
This book provides a practical strategy for obtaining a more complete and accurate geologic site characterization. The strategy and methods to characterize complex geologic settings are readily available. The strategy utilizes readily available technology, basic science and good, old-fashioned common sense resulting in a solid understanding of geologic and even karst or pseudokarst conditions. We provide an introduction to many off-the-shelf methods available for site characterization as well as examples of their application throughout the book. The purpose of a geologic site characterization is to understand the 3-dimensional geologic framework, along with the engineering and hydrologic properties of a site including any man-made impacts. A well-done site characterization is the cornerstone of all geotechnical, groundwater and environmental projects. The geologic conditions, particularly karst conditions, can significantly impact a site including its structural stability, groundwater pathways and potential for rapid transport or traps for contaminants. Once we have adequately characterized the geologic conditions can we carry our remediation, design and construction, model flow, and make risk assessments that are accurate and reliable.
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 comprehensively describes the major ecosystem services in dryland environments that are provided by typical land use, including forestland, grassland and farmland, using the Loess Plateau, Northwest China as an example. It offers extensive information on land policy, implementation and scientific evidence, and discusses the restoration of the degraded Loess Plateau environment, which that brings new challenges in the sustainable use of natural resources, in particular soil and water. It presents a transdisciplinary and up-to-date understanding of interlinkages and competition between different ecosystem services and illustrates benefit sharing among different users and stakeholders, land- management practitioners and local governments. It is a major contribution to the on-going debate on future land-development strategies and identifies areas where there is a need for more research. This book is a valuable resource for students, scientists and policy makers.

In order to provide water security in the twenty-first century, there is universal agreement that a continuation of current policies and extrapolation of trends is not an option. Also clear is that from both water supply and development perspectives, the world's arid and semi-arid regions are those currently and potentially experiencing the highest water stresses. One third of the world's land surface is classified as arid or semi-arid, and about half of all countries are directly affected in some way by problems of aridity. The hydrology of arid and semi-arid areas is also known to be substantially different from that in more humid regions. It is therefore essential that investigation methods appropriate to the former are developed and applied, and that strategies for arid and semi-arid region water resources development recognise the principal characteristics of in-situ hydrological processes.
Hydrometry presents a thorough introduction to the science of hydrometry: the measurement of flow in open channels. Dealing with both traditional techniques and innovative new methods and instruments, in line with the latest ISO standards, this book deals with the main themes of hydrometry: the measurement of water levels and bed levels, of discharge and of sediment transport; it considers the use of flow measuring structures, hydrological networks and the organization of surveys. Dr Boiten has extensive experience of teaching students from many countries and backgrounds, and has distilled this experience into a clear and comprehensive account of hydrology and water resource management. Hydrometry will appeal to graduate students and to professionals engaged in hydrology and the management of water resources.
This wide-ranging selection of original papers covers many aspects of desertification including environmental and weather factors, land management policy, groundwater resources, understanding biodiversity in fragile ecosystems, technological approaches to the study and remedy of desertification.
Flood disasters continue to occur in many countries in the world and cause tremendous casualties and property damage. To mitigate the effects of floods, a range of structural and non-structural measures have been employed including dykes, channelling, flood-proofing property, land-use regulation and flood warning schemes. Such schemes can include the use of Artificial Neural Networks (ANN) for modelling the rainfall run-off process as it is a quick and flexible approach which gives very promising results. However, the inability of ANN to extrapolate beyond the limits of the training range is a serious limitation of the method, and this book examines ways of side-stepping or solving this complex issue.
Egypt is a country of tremendous land resources but limited water resources The area of cultivated land is only 3.2% of the gross area. The river Nile is the main sources of water. In the recent years the Governement established large-scale agricultural projects in light of food security related to the population growth. Expansion of irrigated agriculture has to be predomantly relalized bt increasing the water use efficiency. In Egypt, the dominant irrigation method is surface irrigation, which covers approximately 83% of the irrigated areas. Surface irrigation or gravity methods are generally characterized by a low efficiency. One opportunity to increase the efficiency is to convert surface irrigation to modern irrigation systems, which are generaly highly expensive for a country like Egypt. Another option to increase the efficiency of surface irrigation systems is to convert the traditional irrigation method based on continuous flow to surge flow irrigation. Surge flow irrigation is the intermittent application of water to furrows in a series of relatively short on and off time periods. This study has been carried out to demonstrate the applicability of surge flow irrigation for water saving under the short field conditions that prevail in Egypt. The results indicate that surge flow irrigation is an effective irrigation method to save water and to increase crop production.
For the millions who remain curious about the world around them, but gained little from science at school, this book offers a way forward. Based on live discussions with adults from all walks of life, each chapter begins with an everyday experience, like swallowing a pill or watching a bee on a flower. The main scientific ideas underlying each topic are then explored, so that understanding of a set of fundamental concepts builds up gradually throughout the book. In contrast to more traditional approaches to science learning, topics range freely across the subject areas. The story of Covid, for example includes aspects of biology, chemistry, mathematics and social behaviour. Plain English is used throughout and mathematical expressions are avoided. Key points are illustrated with clear diagrams and photographs. By drawing on questions and perspectives of ordinary people, the book offers an introduction to basic ideas in science as a whole, rather than any one particular subject. For the adult wishing to make good a gap in their understanding it provides a starting point for entering the rich world of popular science.
An entertaining, instructive, diverse, and unusual book, Light and
Dark: An Exploration in Science, Nature, Art and Technology
