This monograph aims at presenting a unified approach to numerical modeling of tsunami as long waves based on finite difference methods for 1D, 2D and 3D generation processes, propagation, and runup. Many practical examples give insight into the relationship between long wave physics and numerical solutions and allow readers to quickly pursue and develop specific topics in greater depth. The aim of this book is to start from basics and then continue into applications. This approach should serve well the needs of researchers and students of physics, physical oceanography, ocean/civil engineers, computer science, and emergency management staff. Chapter 2 is particularly valuable as it fully describes the application of finite-difference methods to the study of long waves by demonstrating how physical properties of water waves, especially phase velocity, are connected to the chosen numerical algorithm. Basic notions of numerical methods, i.e. approximation of the relevant differential equations, stability of the numerical scheme, and computational errors are explained through application to long waves. Finite-difference methods are further developed in major chapters to deal with complex problems that arise in the study of recent tsunamis.

About seventy-one per cent of the Earth's surface is water, and even on dry land we remain closely connected to aquatic life. It provides us with oxygen, food, medicine and materials. Wild waterlife infiltrates our lives in many surprising ways. Every other breath we take is filled with oxygen provided by ocean-dwelling microscopic plants. A type of seaweed provides a means to directly test whether people are infected with viruses, including Covid-19. Robotics design takes inspiration from a pike's ability to accelerate with greater g-force than a Porsche. Wild Waters by Susanne Masters is a celebration of the breadth of wildlife that can be found in and around our varied waterways, from oceans and rivers to rock pools and ponds. Armchair explorers can read a fascinating account of how aquatic plants and animals enrich human life. Swimmers, paddleboarders, dog walkers, families and anyone with a passion for the great outdoors can learn about local wildlife, including when and where to look for different species without causing any harm. With stunning illustrations by Alice Goodridge, Wild Waters provides a tantalising insight into the world beneath the surface.

This book deals with sedimentary sulfides which are the most abundant authigenic minerals in sediments.Special emphasis is given to the biogeochemistry that plays such a central role in the formation of sedimentary sulfides. It will be of interest to scientists in a number of disciplines, including geology, microbiology, chemistry and environmental science. The sulfur system is important to environmental scientists considering the present and future effects of pollution and anoxia.The development of the sulfur system - particularly the characteristics of ocean anoxia over the last 200 Ma - is useful in predicting the future fate of the Earth surface system as well asin understanding the past. The biochemistry and microbiology of the sulfur systemare key to understanding microbial ecology and the evolution of life.
First monograph on sedimentary sulfides, covering the ancient and modern sedimentary sulfide systemsComprehensive, integrating chemistry, microbiology, geology and environmental scienceAll key references are included and discussed

In 1997 sixty-two containers fell off the cargo ship Tokio Express after it was hit by a rogue wave off the coast of Cornwall, including one container filled with nearly five million pieces of Lego, much of it sea themed. In the months that followed, beachcombers started to find Lego washed up on beaches across the south west coast. Among the pieces they discovered were octopuses, sea grass, spear guns, life rafts, scuba tanks, cutlasses, flippers and dragons. The pieces are still washing up today.

Hydrogeomorphology is the science relating to the geographical, geological and hydrological aspects of water bodies and changes to these in response to flow variations and to natural and human caused events. The book covers the aspects of water resources, aquifer properties, structural and drainage patterns, with special reference to latest topics like Rain Water Harvesting, Watershed Development, Remote Sensing, GIS, GPS, DSTM, MCE and TIR. With social, cultural and administrative steps, problems with their solutions and means of sustainable development finding their way in the book, thus making the book a must buy for all concerned. The present book covers detailed studies of hydrogeology and geomorphology. Their simple and accurate presentation by images and tables serves the appetite of not only the students but also of the professionals in the field of agricultural and civil engineering, environment, geology, geomorphology, hydrogeology, hydrology and irrigation.

The Mediterranean region contains a diverse and interesting climate ranging from areas with permanent glaciers to areas of subtropical, semiarid regions. The region is potentially sensitive to climate change and its progress has environmental, social, and economic implications within and beyond the region. Produced by the Mediterranean Climate Variability and Predictability Research Networking Project, this book reviews the evolution of the Mediterranean climate over the past two millennia with projections further into the twenty-first century as well as examining in detail various aspects of the Mediterranean region's climate including evolution, atmospheric variables, and oceanic and land elements. Integrated with this, the book also considers the social and economic problems or vulnerabilities associated with the region. Written and reviewed by multiple researchers to ensure a high level of information presented clearly, Mediterranean Climate Variables will be an invaluable source of information for geologists, oceanographers, and anyone interested in learning more about the Mediterranean climate.

Examining the science of stream restoration, Rebecca Lave argues that the neoliberal emphasis on the privatization and commercialization of knowledge has fundamentally changed the way that science is funded, organized, and viewed in the United States. Stream restoration science and practice is in a startling state. The most widely respected expert in the field, Dave Rosgen, is a private consultant with relatively little formal scientific training. Since the mid-1990s, many academic and federal agency - based scientists have denounced Rosgen as a charlatan and a hack. Despite this, Rosgen's Natural Channel Design approach, classification system, and short-course series are not only accepted but are viewed as more legitimate than academically produced knowledge and training. Rosgen's methods are now promoted by federal agencies including the Environmental Protection Agency, the U.S. Forest Service, the U.S. Fish and Wildlife Service, and the Natural Resources Conservation Service, as well as by resource agencies in dozens of states. Drawing on the work of Pierre Bourdieu, Lave demonstrates that the primary cause of Rosgen's success is neither the method nor the man but is instead the assignment of a new legitimacy to scientific claims developed outside the academy, concurrent with academic scientists' decreasing ability to defend their turf. What is at stake in the Rosgen wars, argues Lave, is not just the ecological health of our rivers and streams but the very future of environmental science.
