Computational hydraulics and hydrologic modeling are rapidly developing fields with a wide range of applications in areas ranging from wastewater disposal and stormwater management to civil and environmental engineering. The fields are full of promise, but while an abundance of literature now exists, it contains a plethora of new terms that are not always defined.

Computational Hydraulics and Hydrology: An Illustrated Dictionary defines more that 4000 basic terms and phrases related to water conveyance with emphasis on computational hydraulics and hydrologic modeling. Compiled by Nicolas G. Adrien, a noted consulting engineer with three decades of experience, this dictionary includes detailed references to actual modeling studies, nearly 100 illustrations, 150 equations and formulas, and many notations. It also includes a chapter of application examples and another containing more than 6000 other related terms with a list of resources where interested readers can find further definitions.

Other dictionaries and glossaries related to these areas tend to be either dated or much narrower in scope. This dictionary offers broad, practice-based coverage of terms culled directly from the latest texts, references, and actual engineering reports. Computational Hydraulics and Hydrology: An Illustrated Dictionary stands alone in providing ready access to the vocabulary of these subjects.

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.

The text covers the problems concerning optical properties and remote sensing of turbid and surface-polluted oceans and lakes. In four chapters Helgi Arst compares remote sensing data with data collected from similar examination of clean waters. Chapter 1 provides an overview of the main radiative and remote sensing characteristics and provides discussion on the properties of optically active substances (OAS) in the water and their variability and concentration, drawing on original data obtained in the Baltic Sea region. Chapter 2 focuses on the investigation of the influence of surface oil slicks on the reflection and absorption of solar radiation for both calm and ruffled sea surfaces. A model is provided for determining the temperature and the reflected component in upwelling rough seas. Chapter 3 provides remote sensing results obtained mainly for the Baltic Sea region, including some lakes. Correlations between the concentrations of OAS, water transparency and total remote sensing reflectance are investigated. Chapter 4 deals with subsurface irradiance and optical classification of turbid waters. This chapter analyses the different criteria of the euphotic depth, drawing on a semi-empirical model for the estimation of underwater light scattering. The conclusion provides discussion on the results obtained.

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.

This publication is divided into four sections: climate change and environmental concerns; data analysis and management; fisheries management and ecology; and GIS, geospatial analysis, and localization. This publication is an ideal reference source for oceanographers, marine and maritime professionals, researchers, and scholars interested in current research on various aspects of oceanography and coastal informatics.

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. -- .

Arid and semi-arid regions can be defined as environments in which water is the limit ing factor for bio-systems. This means that survival of life in these regions involves a constant struggle to obtain this limited commodity and draw the maximum benefit out of it. However, despite the difficulties for plants, animals, and man to live in, these regions, they are being utilized more and more because of the pressure of world population growth. This is expressed in the expansion of agricultural activities in desert lands as well as by the formation and rapid growth of urban and industrial centers. These trends result in a growing demand for water on the one hand, and the disposal of vast amounts of waste water, as well as other types of refuse, on the other. Meeting the first demand, namely, supplying water to the agricultural communities and urban centers, involves, in many instances, the over-exploitation and misuse of nat ural water resources. The surplus of waste water, sometimes highly loaded with toxic compounds, is likely to cause irreversible damage to the environment. The geoscientists and engineers face a challenge on two conflicting fronts. Success on one front, namely, in answering the full demand for water, may lead to an increase in the pollution of the environment by waste water."

" ... as soon as one has traversed the greater part of the wild sea, one comes upon such a huge quantity of ice that nowhere in the whole world has the like been known." "This ice is of a wonderful nature. It lies at times quite still, as one would expect, with openings or large fjords in it; but sometimes its movement is so strong and rapid as to equal that of a ship running before the wind, and it drifts against the wind as often as with it." Kongespeilet - 1250 A.D. ("The Mirror of Kings") Modern societies require increasing amounts influence on the water mass and on the resulting of scientific information about the environment total environment of the region; therefore, cer tain of its characteristics will necessarily be in whieh they live and work. For the seas this information must describe the air above the sea, included."

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.

Since human beings first appeared on the earth, we have changed land cover and land use for our own purposes, such as conveniences and high productivity. As a result of the land cover and land use changes, many serious environmental problems occur on the earth. Studying meteorological and hydrological effects of vegetation and land cover/use changes helps us to understand the environmental changes and problems happening near the earth surface, because the vegetation distributes the solar energy and water on the earth surface into atmosphere and geosphere. Subsurface hydrological responses to land cover and land use changes have drawn only regional environmental concerns, although global change caused by biosphere change has been studied in various scientific fields. The changes in land cover and land use alter water, solute and heat cycles in basins and elements of those balances, including evapotranspiration, groundwater recharge rate, discharge rates into rivers or ocean and soil moisture content, which are directly or indirectly related to the global environmental issues. Therefore, the changes in biosphere may substantially alter the subsurface hydrological system. For instance, increased groundwater recharge rates following clearing forest into grasses might be one consequence resulting in rising water tables and salinization.

The applications of stochastic methods in design by reliability include the better utilisation of hydrological information. With statistical methods one can evaluate the safety component of hydraulic systems. Based on these, extra safety features can be added to ensure the reliable performance of an hydraulic system. One such example is the design of a dam, which features a number of random variables, each with a very distinct and quite different probability function. This book reports on developments in stochastic hydraulics across a wide range of applications, including river hydraulics, sediment transportation, waves and coastal processes, hydrology, hydraulic works and structure, and environmental hydraulics.
