Increasing population, expanding industry and commerce, and tourism are placing added pressures on an already highly-utilized coastal zone. This book, through a series of case studies, illustrates the variety of changes already made along the coastlines of the world. The examples used are mainly from China, Japan, The Netherlands, and the United States, all countries with extensively engineered shorelines. Modifications emphasized include those associated with protection against coastal erosion, building of artificial beaches and islands, reclamation for aquaculture and agriculture, and the construction of harbors. The information in this book should be useful for all planners and engineers involved in the construction of coastal engineering works and for students interested in coastal modification.
Research in Antarctica in the past two decades has fundamentally changed our perceptions of the southern continent. This volume describes typical terrestrial environments of the maritime and continental Antarctic. Life and chemical processes are restricted to small ranges of ambient temperature, availability of water and nutrients. This is reflected not only in life processes, but also in those of weathering and pedogenesis. The volume focuses on interactions between plants, animals and soils. It includes aspects of climate change, soil development and biology, as well as above- and below-ground results of interdisciplinary research projects combining data from botany, zoology, microbiology, pedology, and soil ecology.
Since the computing revolution, modelling has become the most important way in which we further our knowledge about how the sea moves and how the processes in the sea operate. The coast and the continental shelf are two of the most important areas of the sea to understand. Coastal and Shelf Sea Modelling is therefore very timely and important. In this text, modelling the processes that occur in the sea is motivated continually through real life examples. Sometimes these are incorporated naturally within the text, but there are also a number of case studies taken from the recent research literature. These will be particularly valuable to students as they are presented in a style more readily accessible than that found in a typical research journal. The motivation for modelling is care for the environment. The well publicised problem of global warming, the phenomenon of El Nino, more localised pollution scares caused by tanker accidents and even smaller scale coastal erosion caused by storms all provide motivation for modelling and all get coverage in this text. Particularly novel features of the book include a systematic treatment of the modelling process in a marine context, the inclusion of diffusion in some detail, ecosystems modelling and a brief foray into wave prediction. The final chapter provides the reader with the opportunity to do some modelling; there are many worked examples followed by exercises that readers can try themselves. All answers are provided. Throughout, the style is informal and the technicalities in term of mathematics are kept to a minimum. Coastal and Shelf Sea Modelling is particularly suitable for graduate marine and oceanographic modelling courses, but will also prove useful to coastal engineers and students at any level interested in the quantitative modelling of marine processes. It is stressed that only a minimal level of mathematics (first year calculus or less) is required; the style and content is introductory.
Coastal and marine ecosystems, some severely degraded, other still
pristine, control rich resources of inshore environments and
coastal seas of Latin America's Pacific and Atlantic margins.
Conflicts between the needs of the region's nations and diminishing
revenues and environmental quality have induced awareness of
coastal ecological problems and motivated financial support for
restoration and management.
Anthropogenic transformation of the coastal zone continues at a steady pace, especially in the developing maritime countries, where coastal resources are often crucial to national economies. However, exploitation of these resources is often indiscriminate, ill planned, or carried out without adequate scientific knowledge. This leads to rapid resource depletion, and often irreversible environmental degradation. The 1992 Rio de Janeiro UN Conference on Environment and Development recognized the expediency of an integrated and sustainable use of all coastal resources, functions and services grounded on sound scientific data. The present volume is based on the 1994 international workshop Integrated Coastal Zone Management, and brings together contributions by leading specialists both on basic concepts and on applications of coastal management. The work is divided into six parts, dealing with the conceptual framework of ICZM; regional and global aspects of coastal management; environmental assessment in ICZM; capacity building and technology transfer; monitoring and environmental analysis; and case studies and status of ICZM plans. The book also incorporates an interactive ICZM planning module, COSMO, which can be of use in designing a management plan for a coast. Attention is also given to long-term environmental effects of present-day actions. It is hoped that COSMO will prove an additional learning tool for ICZM practitioners and enhance the value of the book. This work is intended to give a broad coverage of conceptual and technical aspects of ICZM, and will be of use to operational executives as well as students of ICZM, environmental economists, policy-makers and senior managers in the international development agencies and governmental and non-governmental organizations. It can be recommended as a textbook and as a reference work.
The Upper Adriatic Sea basin comprises a very precarious coastal environment subject to continuous changes which prove appreciable not only over the geological scale but also in historical and modern times. According to some Authors the Venice Lagoon was formed 2000-3000 years ago, and other lagoons (e. g. the Grado Lagoon in the northernmost part of the Adriatic) are even more recent. In addition to lagoons, the Upper Adriatic coastal area includes salt and fresh-water marshes and reclaimed land separated by several watercourses originating from the Alpine and Apennine ranges with a ground elevation not exceeding in many places 2 m above the mean sea l. evel (msl). A significant fraction of this lowland is already now below msl because of natural and anthropogenic land subsidence, land reclamation and sea level rise occurred over the last century. Natural land subsidence is still under way as a result of deep downward tec tonic movement and consolidation of soils deposited in the most recent time. An thropogenic subsidence is primarily due to groundwater pumping for agricultural, industrial, civil, and tourist use, and to gas withdrawal from a large number of gas fields scattered through the Upper Adriatic basin, and may still continue, al though at a reduced rate, in the years to come. At the same time msl is expected to rise in the next century due to global climate change, mainly because of the greenhouse effect.
This book describes the entire coast and beaches and barrier systems of Australia. It covers the coastal processes and systems that form and impact Australia's 30.000 km coast, 12.000 beaches and 2750 barrier systems. These processes include geology, geomorphology, climate, waves, tides, currents, sediment supply, as well as coastal ecosystems. The coast is divided into tropical northern and southern temperate provinces, within which are seven divisions, 23 regions and 354 coastal sediment compartments each of which is described in detail in the 34 chapters. Within these systems are the full range of wave through tide-dominated beaches and barriers ranging from cheniers to massive transgressive dune systems together with a range of onshore and longshore sand transport systems. This is an up to date reference for the entire coast, its present condition and likely responses to the impacts of climate change.

This book presents advanced knowledge on the relationships between climate change and agriculture, and various adaptation techniques such as low tillage, salt-adapted beneficial microbes and closed systems. Climate change is unavoidable but adaptation is possible. Climate change and agriculture are interrelated processes, both of which take place on a global scale. Climate change affects agriculture through changes in average temperatures, rainfall and climate extremes; changes in pests and diseases; changes in atmospheric carbon dioxide; changes in the nutritional quality of some foods; and changes in sea level.
The Management Plan focuses on the special resource features of Gray's Reef. The Plan is designed to inform sanctuary users and the general public about the Sanctuary and the various activities that are planned for the site over time.
The Gray's Reef live bottom is proposed for marine sanctuary status in recognition of its distinctive conservation, research, recreational, ecological and aesthetic values which are in need of protection and comprehensive management. This document presents the Final Environmental Impact Statement on the Proposed Gray's Reef Marine Sanctuary.
Monitoring changes in the intertidal zone of rocky shores has never been more critical. This sensitive habitat at the interface of land and ocean may well be the marine equivalent of the canary in a coal mine as we advance into an era of global climate change. This handbook describes effective methods and procedures for monitoring the ecological and environmental status of these areas. Written by three collaborating authors with extensive field experience, it provides critical discussions and evaluation of the various sampling techniques and field procedures for studies of intertidal macroinvertebrates, seaweeds, and seagrasses. Rather than prescribing standard protocols or procedures, the authors break down the decision-making process into various elements so investigators can become aware of the advantages and disadvantages of choosing a particular method or approach. Chapters discuss topics such as site selection, field sampling layouts and designs, selection of sampling units, nondestructive and destructive methods of quantifying abundance, and methods for measuring age, growth rates, size, structure, and reproductive condition.
The inaction of nation states and international bodies has posed significant risks to the environment. By contrast, cities are sites of action and innovation. In Sustainability, Citizen Participation, and City Governance, contributors researching in the areas of law, urban planning, geography, and philosophy identify approaches for tackling many of the most challenging environmental problems facing cities today. Sustainability, Citizen Participation, and City Governance facilitates two strands of dialogue about climate change. First, it integrates legal perspectives into policy debates about urban sustainability and governance, from which law has typically stood apart. Second, it brings case studies from Quebec into a rare conversation with examples drawn from elsewhere in Canada. The collection proposes humane and inclusive processes for arriving at effective policy outcomes. Some chapters examine governance mechanisms that reconcile clashes of incommensurable values and resolve conflicts about collective interests. Other chapters provide platforms for social movements that have faced obstacles to communicating to a broad public. The collection's proposals respond to drastic changes in urban environments. Some changes are imminent. Others are upon us already. All threaten the present and future well-being of urban communities.
Beyond the Megacity connects and reconnects the global debate on the contemporary urban condition to the Latin American tradition of seeing, considering, and theorizing urbanization from the margins. It develops the approach of "peripheral urbanization" as a way to integrate the theoretical agendas belonging to global suburbanisms, neo-Marxist accounts of planetary urbanization, and postcolonial urban studies, and to move urban theory closer to the complexity and diversity of urbanization in the Global South. From an interdisciplinary perspective, Beyond the Megacity investigates the natures, causes, implications, and politics of current urbanization processes in Latin America. The book draws on case studies from various countries across the region, covering theoretical and disciplinary approaches from the fields of geography, anthropology, sociology, urban studies, agrarian studies, and urban and regional planning, and is written by academics, journalists, practitioners, and scholar-activists. Beyond the Megacity unites these unique perspectives by shifting attention to the places, processes, practices, and bodies of knowledge that have often been neglected in the past.

Take this book to the beach; it will open up a whole new world. Illustrated throughout with color photographs, maps, and graphics, it explores one of the planet's most dynamic environments - from tourist beaches to Arctic beaches strewn with ice chunks to steaming hot tropical shores. "The World's Beaches" tells how beaches work, explains why they vary so much, and shows how dramatic changes can occur on them in a matter of hours. It discusses tides, waves, and wind; the patterns of dunes, washover fans, and wrack lines; and the shape of berms, bars, shell lags, cusps, ripples, and blisters. What is the world's longest beach? Why do some beaches sing when you walk on them? Why do some have dark rings on their surface and tiny holes scattered far and wide? This fascinating, comprehensive guide also considers the future of beaches, and explains how extensively people have affected them - from coastal engineering to pollution, oil spills, and rising sea levels.
The Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.
This book is based on the author's 49 years of experience as a practicing coastal engineer and 34 years as professor of coastal engineering and management at Queen's University. The book is therefore thoroughly practical in nature, but it also reflects newly relevant issues, such as consequences of failure, impacts of rising sea levels, aging infrastructure, real estate development, and contemporary decision making, design and education.This textbook is useful for undergraduate students, postgraduate students and practicing engineers. It covers waves, structures, sediment movement, coastal management, and contemporary coastal design and decision making. It presents both basic principles and engineering solutions. It discusses the traditional methods of analysis and synthesis (design), but also contemporary design methodologies, such as working with environmental impacts.The second edition expanded greatly on the topics of failure and resilience that surfaced as a result of recent disasters from hurricane surges and tsunamis. It updated the discussion of design and decision making for the 21st century, with many new examples.This third edition develops some of these topics further, but its largest new changes is the chapter on climate change. This chapter presents the basics of climate change and then goes on to stress the practical implications of the impacts of climate change, focusing on what is of importance to coastal and fluvial specialists.
This textbook is a self-contained introduction to tides that will be useful for courses on tides in oceans and coastal seas at an advanced undergraduate and postgraduate level, and will also serve as the go-to book for researchers and coastal engineers needing information about tides. The material covered includes: a derivation of the tide-generating potential; a systematic overview of the main lunar periodicities; an intuitive explanation of the origin of the main tidal constituents; basic wave models for tidal propagation (e.g. Kelvin waves, the Taylor problem); shallow-water constituents; co-oscillation and resonance; frictional and radiation damping; the vertical structure of tidal currents; and a separate chapter on internal tides, which deals with ocean stratification, propagation of internal tides (vertical modes and characteristics) and their generation. Exercises are provided in each chapter.
The ICE Coasts, Maritime Structures and Breakwaters conference series, sponsored by the ICE for over thirty years, is the leading international forum for the presentation of the latest developments in coastal and maritime engineering. The eleventh conference, Realising the Potential, was held in Liverpool from 5th to 7th September 2017. Across the three days, it was attended by over 300 delegates and saw 90 papers presented. This book contains the full discussion notes from each session at the conference as well as 'innovation spotlights' detailing short presentations on new and developing practices and processes. The topics for 2017 focused on describing the design, construction, analysis and performance of a wide range of maritime structures. The contents contain the latest research and developments and up-to-date guidance and innovations as well as practical lessons learned from experience. The 90 papers presented here cover a diverse range of topics including - construction in ports - working in marine environments - challenges at the coast - coastal developments - breakwater armour - ecological aspects of design - developments in overtopping - waves on structures. With contributions from those in industry and academia and featuring a wide range of international case studies, these proceedings offer an essential reference for coastal engineers and professionals.
This book is the outcome of rigorous and continuous research work done by the author over about three decades on the open ecosystem and dynamic environment of the estuarine Sunderbans. The objective of this work is to identify the field and factors changing gradually upon this active delta over the years, decades and centuries. The deltaic Sunderbans yet not mature enough, has been changing in its natural course with time. Further, anthropogenic interferences disturb the environments and accelerate degradation of nature of this fragile ecosystem simultaneously. Roles played by almost all the agents including man and environment and their involvement are identified for the changing environmental scenario of the Sunderbans. The book is befitted for the researchers and students for the post graduate levels. The Sunderbans, a UNESCO World Heritage Site covering parts of Bangladesh and the southern tip of Indian state of West Bengal, is a part of world's largest deltaic plain of fluvio-marine deposit formed by the Ganges and Brahmaputra at the confluence of the Bay of Bengal. It is the largest single block of tidal halophytic mangrove forest in the world, conspicuous for its great size and biodiversity. With an enormous network of channels and creeks, tidal inundation twice daily, Sunderbans mangroves wetland is a dynamic and complex ecosystem, which undergoes continuous processes of erosion and accretion. Natural processes like changes in local hydrology, sediment motion under wind, wave and tidal action, beach dynamics, regional and global processes like sea level rise as well as the impact of human interference in the form of reclamation of forest land, changes in land use patterns, coastal urbanizations etc are the lead factors for the changes in the environmental scenario of Sunderbans.
Humans have had a long relationship with the ebb and flow of tides on river deltas around the world. The fertile soils of river deltas provided early human civilizations with a means of farming crops and obtaining seafood from the highly productive marshes and shallow coastal waters associated with deltas. However, this relationship has at times been both nurturing and tumultuous for the development of early civilizations. The vicissitudes of seasonal changes in river flooding events as well as frequently shifting deltaic soils made life for these early human settlements challenging. These natural transient processes that affect the supply of sediments to deltas today are in many ways very similar to what they have been over the millennia of human settlements. But something else has been altered in the natural rhythm of these cycles. The massive expansion of human populations around the world in both the lower and upper drainage basins of these large rivers have changed the manner in which sediments and water are delivered to deltas. Because of the high density of human populations found in these regions, humans have developed elaborate hydrological engineering schemes in an attempt to "tame" these deltas. The goal of this book is to provide information on the historical relationship between humans and deltas that will hopefully encourage immediate preparation for coastal management plans in response to the impending inundation of major cities, as a result of global change around the world. |
