During the 1980's a wealth of information was reported from field and laboratory experiments in order to validate andlor modify various aspects of the surface layer Monin-Obukhov (M-O) similarity theory for use over the sea, and to introduce and test new concepts related to high resolution flux magnitudes and variabilities. For example, data from various field experiments conducted on the North Sea, Lake Ontario, and the Atlantic experiments, among others, yielded information on the dependence of the flux coefficients on wave state. In all field projects, the usual criteria for satisfying M-O similarity were applied. The assumptions of stationarity and homogeneity was assumed to be relevant over both small and large scales. In addition, the properties of the outer layer were assumed to be "correlated" with properties of the surface layer. These assumptions generally required that data were averaged for spatial footprints representing scales greater than 25 km (or typically 30 minutes or longer for typical windspeeds). While more and more data became available over the years, and the technology applied was more reliable, robust, and durable, the flux coefficients and other turbulent parameters still exhibited significant unexplained scatter. Since the scatter did not show sufficient reduction over the years to meet customer needs, in spite of improved technology and heavy financial investments, one could only conclude that perhaps the use of similarity theory contained too many simplifications when applied to environments which were more complicated than previously thought.

This Workshop was organized to assess the status of knowledge on the behaviour of phosphorus in sediments and to define gaps and reassess research strategies, particularly with respect to prevalent methodology and future approach; and to define gaps and reassess research strategies for water management measures in aquatic ecosystems, especially in relation to the release of phosphorus from the sediments and its impact on the functioning of the whole system.

Although numerous books have been written on both monitoring and modelling of coastal oceans, there is a practical need for an introductory multi-disciplinary volume to non-specialists in this field. The articles commisioned for this book, organized into four major themes, are written by experts in their disciplines while the text is intended for scientists who do not have extensive training in marine sciences and coastal zone management. As such, the articles in this monograph can be a valuable reference for practicing professionals. The first section introduces the complex physical processes with main emphasis on waste disposal in the coastal ocean. Following this, examples of instrumentation techniques that are commonly used for measuring different properties of oceans are discribed. Coastal and estuarine transport and dispersion modelling is introduced in the next section with examples from different parts of the world. The last section provides an overview of coastal disasters such as tropical cyclones, storm surges and oil spills.

Eugene Sharkov, of the Space Research Institute in Moscow, has here put together the most comprehensive description of the physical findings of an investigation into the spatio-temporal characteristics of the gravity of breaking waves.

Numerous practical applications and illustrations are provided from air-borne, ship-borne and laboratory up-to-date experiments.

This volume discusses the general physics of debris flows and various approaches to modeling - including the SEGMENT-Landslide approach - as well as the pros and cons of these approaches and how other approaches are sub-sets of the SEGMENT-Landslide approach. In addition, this volume will systematically unify the concepts of vadose zone hydrology and geotechnical engineering, with special emphasis on quantifying ecosystem consequences of storm-triggered landslides in a warmer climate setting. The reader will find a comprehensive coverage of concepts ranging from hillslope hydrology, porous granular material rheology and the fundamentals of soil properties, to state-of-the-art concepts of enhanced hydrological cycle with climate warming and a discussion of new approaches for future research.

This book explores how a long-term innovation can take place based on historical analyses of the development of reverse osmosis (RO) membrane from the early 1950s to the mid-2010s. The RO membrane is a critical material for desalination that is a key to solve water shortages becoming serious in many places of the world. The authors conducted in-depth field studies as well as analyses of rich archival data to demonstrate how researchers, engineers, managers, entrepreneurs, and policymakers interacted each other for this material innovation to be realized. A series of historical analyses in this book uncovered that initial government supports, strategic niche markets, emergence of breakthrough technology, and company-specific rationales played significant roles for companies to overcome four types of uncertainty, technological, market, competition, and social/organizational ones, and enabled the companies to persistently invest in the development and commercialization of the RO membrane. This book depicts that innovation does not arise on a sudden, but that it is actualized through long lasting process with turns and twists, which is driven by many non-economic rationales beyond economic motives.

It provides a comprehensive review and discusses the latest research findings on the ecosystem of this sub-arctic zone. The topics addressed include suspended particulate matter as a main source and proxy of the sedimentation processes in the White Sea; vertical fluxes of dispersed sedimentary matter and absolute masses in the White Sea; and the development history and quaternary deposits of the modern White Sea basin. The authors closely examine the abundance and species composition of microalgae associations and the environmental conditions in the bottom sediments of the White Sea, namely, heavy metal accumulation and aliphatic and polycyclic aromatic hydrocarbons. The book ends contain a summary of the key conclusions and recommendations. Together with the companion volume Biogeochemistry of the Atmosphere, Ice and Water of the White Sea: The White Sea Environment Part I, it offers an essential source of information for postgraduate students, researchers, and stakeholders alike.

Ten years ago, de Loor and co-workers at TNO, The Netherlands, were the first to report bottom topography patterns in real aperture radar (RAR) images of the southern North Sea. At that time, this was a real puzzle. The skin depth of microwaves for sea water is only of the order of centimeters while the sea bottom is about 20 meters below the surface. Electromagnetic radiation therefore cannot probe the bottom directly. Similar phenomena were found in radar imagery from SEASAT and SIR-AlB synthetic aperture radars (SAR's) of Nantucket Shoals, the English Channel and many other coastal areas. Since then theory and ocean field experiments (Le., Phelps Bank, Georgia Straits, SARSEX, TOWARD, FASINEX, etc.) have advanced our understanding considerably. We now know that these surface signatures are the results of surface currents, perturbed by the bottom topography, which refract the propagation and modulate the energy of (short) surface waves so as to cause microwave backscatter power variations. Hence, any large scale ocean features containing nonuniform surface currents (i.e. internal waves, eddies, fronts, etc.) will cause similar manifestations in the radar imagery by means of current-wave-microwave interactions. Observations confirm this.

The demand on land to produce food, for urban development such as housing, industry, shopping areas, infrastructure and also for recreation has increased during the history of mankind. This has resulted in such activities as the reclamation of swamps, flood plains, tidal areas and even lakes by impoldering. Model simulations can be use to gain insight into the system behaviour of different land use and soil composition under temperate humid and humid tropic conditions, The existing package OPOL, based on a non steady model, was further developed to the version OPOL5 for the simulation of hydrological conditions and optimization of the main components of water management systems in polder areas in the temperate humid and humid tropical zone. This model reveals a system's behaviour as well as the effects of variation in the main components of the systems to the overall costs. For example, the designs of pumped drainage systems in polder areas can be optimized by varying the main components until the annual equivalent costs are minimum. A GIS tool has been used to complement OPOL5 for the simulation of the real situation in an area with respect to land use, damage, topography, and soil type. The model package has been applied to two case studies: one in the temperate humid zone, namely the Netherlands and to Thailand in the humid tropical zone.

This collection of essays and design case studies explores a range of ideas and best practices for adapting to dynamic waterfront conditions while incorporating nature conservation in urbanized coastal areas. The editors have curated a selection of works contributed by leading practitioners in the fields of coastal science, community resilience, habitat restoration, sustainable landscape architecture and floodplain management. By highlighting ocean-friendly innovations and strategies being applied in coastal cities today, this book illustrates ways to cohabit with many other species who share the waterfront with us, feed in salt marshes, bury their eggs on sandy beaches, fly south over cities along the Atlantic Flyway, or attach themselves to an oyster reef. This book responds to the need for inventive, practical, and straightforward ways to weather a changing climate while being responsible shoreline stewards.

Environmental politics has traditionally been a peripheral concern for international relations theory, but increasing alarm over global environmental challenges has elevated international society's relationship with the natural world into the theoretical limelight. IR theory's engagement with environmental politics, however, has largely focused on interstate cooperation in the late twentieth century, with less attention paid to how the eighteenth- and nineteenth-century quest to tame nature came to shape the modern international order. The ideal river examines nineteenth-century efforts to establish international commissions on three transboundary rivers - the Rhine, the Danube, and the Congo. It charts how the Enlightenment ambition to tame the natural world, and human nature itself, became an international standard for rational and civilized authority and informed our geographical imagination of the international. This relationship of domination over nature shaped three core IR concepts central to the emergence of early international order: the territorial sovereign state; imperial hierarchies; and international organizations. The book contributes to environmental politics and international relations by highlighting how the relationship between society and nature is not a peripheral concern, but one at the heart of international politics. -- .

The Danube River Basin is shared by 19 countries and there is no river basin in the world shared by so many nations. Covering an area of about 800,000 km, it is Europe's second largest river basin and home to 83 million people of different cultures, languages and historical backgrounds.

Management of common water sources and overcoming difficulties caused by droughts and floods requires co-operation between these countries. In the past twenty years political turbulence has caused an increase in the number of countries included, making co-operation difficult at times. Nevertheless several projects were launched and a number of reports were produced. In 2008, at the 22nd Working Meeting of the Regional Hydrological Co-operation of the Danube Countries in the framework of IHP/UNESCO at the XXIVth Conference of the Danubian Countries, it was decided that these reports would be summarised in one special publication. It was also agreed to include additional reports serving the common interest.

This publication therefore brings together the reports and papers related to regional co-operation. It is the result of a major collaboration and examines a broad range of topics. These include hydrological forecasting and hydro-meteorological extremes, global climate change and hydrological processes, water management, and developments in hydrology. The book includes the efforts of many hydrologists and technical staff from different Universities and Agencies from all countries of the Danube River Basin. "

In the 20th century, water management focused on the local scale of interest. In the 21st century we will be facing changes in quantity and quality of our water cycle. Triggering forces behind these new challenges are industrialisation, population growth and the delayed awareness that we are to expect a global change. The magnitude and distribution of global changes are not exactly predictable, because we live in an always changing environment, are faced with severe and interfering processes, which all are not yet sufficiently understood. Therefore, to shoulder this task, hydrology should embrace more integrative and interdisciplinary approaches than already existing and has to achieve more flexibility in assessments and decisions. To better approach this challenge, catchments related solutions are more important than local solutions, to satisfy the water demand of agriculture, ecosystems, industry and the private sector. And we should keep in mind that the environment has a "sustainable memory" and our knowledge about attenuation capacities and resilience of the environment is still low.
