This book provides detailed information on the history, analysis and applications of chlorine and bromine isotope geochemistry. Chlorine and bromine are geochemically unique as they prefer to exist as single charged negative ions. For this reason isotope fractionation reflects mostly processes that are not related to changes in the redox state and this fractionation is generally modest. The book will describe the processes that are most easily detected using these isotopes. Also isotope variations, and processes that cause them, measured in oxidised species such as perchlorates and in organic molecules will be described in this book.

Uranium is an element to be found ubiquitous in rock, soil, and water. Uranium concentrations in natural ground water can be more than several hundreds g/l without impact from mining, nuclear industry, and fertilizers. Considering the WHO recommendation for drinking water of 15 g/l (has been as low as 2 g/l before) due to the chemical toxicity of uranium the element uranium has become an important issue in environmental research. Besides natural enrichment of uranium in aquifers uranium mining and milling activities, further uranium processing to nuclear fuel, emissions form burning coal and oil, and the application of uranium containing phosphate fertilizers may enrich the natural uranium concentrations in soil and water by far. In October 1995 the first international conference on Uranium Mining and Hydrogeology (UMH I) was held in Freiberg being organized by the Department of Geology at the Technical University Bergakademie Freiberg by the support of the Saxon State Ministry of Geology and Environment. Due to the large scientific interest in the topic of uranium a second conference (UMH II) took place in Freiberg in September 1998. Furthermore, in September 2002 scientists working on the topic of uranium mining and hydrogeology attended the third conference (UMH III) which was jointly held together with the International Mine Water - sociation (IMWA) Symposium 2002. The reviewed papers and posters of the 2002 conference have been published by Springer entitled Uranium in the aquatic en- ronment (edited by Merkel, Planer-Friedrich and Wolkersdorfer).

In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers. The basic approach of this book is to accurately describe the underlying physics of groundwater flow and solute transport in heterogeneous porous media, starting at the microscopic level, and to rigorously derive their mathematical representation at the macroscopic levels. The well-posed, macroscopic mathematical models are formulated for saturated, single phase flow, as well as for unsaturated and multiphase flow, and for the transport of single and multiple chemical species. Numerical models are presented and computer codes are reviewed, as tools for solving the models. The problem of seawater intrusion into coastal aquifers is examined and modeled. The issues of uncertainty in model input data and output are addressed. The book concludes with a chapter on the management of groundwater resources. Although one of the main objectives of this book is to construct mathematical models, the amount of mathematics required is kept minimal.

The presence of water on Earth is discussed in this book using various theories about its origin as a basis. These theories include a massive degassing of the primitive parent bodies that built our planet as well as a late addition from comets that collided with the Earth s surface. The extraordinary physico-chemical properties of the water molecules, combined with its abundance and distribution over the Earth s surface, have contributed to regulating the global climate and favoring species evolution for more than 4 billion years. The early emergence of life in the deep ocean and its further diversification were closely linked to the global water cycle whose dynamics result from the energy balance between solar radiation and the internal heat flux of the Earth. Chapter 1 of this book deals with the extraordinary physico-chemical properties of the water molecule while Chapter 2 provides insight on theories regarding the origin of water on Earth. In the third chapter, the author focuses on the chemical composition of the main water reservoirs of our planet. Chapters 4 and 5 discuss water s relationship with plate tectonics and life, respectively. The sixth and final chapter uses stable isotope tracking to look into the water cycle and past climates. Contents 1. Water: A Molecule Endowed with Extraordinary Physicochemical Properties. 2. Theories about the Origin of Water on Earth. 3. The Main Water Reservoirs on Earth and their Chemical Composition. 4. Water and Plate Tectonics. 5. Water and Life. 6. Stable Isotope Tracking: Water Cycles and Climates of the Past.

The availability of Earth observation and numerical weather prediction data for hydrological modelling and water management has increased significantly, creating a situation that today, for the same variable, estimates may be available from two or more sources of information. Yet, in hydrological modelling, usually, a particular set of catchment characteristics and input data is selected, possibly ignoring other relevant data sources. In this thesis, therefore, a framework is being proposed to enable effective use of multiple data sources in hydrological modelling. In this framework, each available data source is used to derive catchment parameter values or input time series. Each unique combination of catchment and input data sources thus leads to a different hydrological simulation result: a new ensemble member. Together, the members form an ensemble of hydrological simulations. By following this approach, all available data sources are used effectively and their information is preserved. The framework also accommodates for applying multiple data-model integration methods, e.g. data assimilation. Each alternative integration method leads to yet another unique simulation result. Case study results for a distributed hydrological model of Rijnland, the Netherlands, show that the framework can be applied effectively, improve discharge simulation, and partially account for parameter and data uncertainty.

This book provides a comprehensive description of groundwater resources in Ethiopia and its various dimensions (groundwater as resource, environmental functions, and socioeconomics). The prevailing knowledge of groundwater resources in Ethiopia (or elsewhere in Sub Saharan Africa) was based on geological and stratigraphic framework known nearly four decades ago (mainly 1960's and 70's). Thanks to the substantial geoscientific research since the 70's a new set of relevant geological/stratigrahpic data has been created that helps to re-define our understanding of groundwater resources in Africa as a whole and in Ethiopia in particular: a) For the first time the basement aquifer of Ethiopia has been described hydrogeologically based on genesis of regoliths (deep weathering and striping history); clear regional difference in groundwater potential is shown for the first time; comparative accounty has been given regarding groundwater occurrence in the generally low grade basement rocks of Ethiopia (Arabian Nubian shield) and high grade basement rocks of the rest of Africa. b) For the first time groundwater occurrence in multilayred sedimentary rocks account for spatial variation in degree of karstification; deformation history, and stratigraphy. c) The vast volcanic aquifers of Ethiopia which have previously classified based on their ages are now reclassified based on age, morphology (eg. groundwater in plateau volcanics, groundwater in shield volcanics) and aquifer structure. d) The loose alluvio lacustrine sediments which were known as least extensive in previous works based on areal cover are in fact shown to host the most voluminous groundwater resources in Ethiopia. These aquifers have now been described based on their geomorphology, extent, and genesis. The aim of this book is to use these newly created knowledge to redefine the understanding of groundwater resources in Ethiopia.

This thesis deals with the evaluation of surface and groundwater quality changes in the periods of water scarcity in river catchment areas. The work can be divided into six parts. Existing methods of drought assessment are discussed in the first part, followed by the brief description of the software package HydroOffice, designed by the author. The software is dedicated to analysis of hydrological data (separation of baseflow, parameters of hydrological drought estimation, recession curves analysis, time series analysis). The capabilities of the software are currently used by scientist from more than 30 countries around the world. The third section is devoted to a comprehensive regional assessment of hydrological drought on Slovak rivers, followed by evaluation of the occurrence, course and character of drought in precipitation, discharges, base flow, groundwater head and spring yields in the pilot area of the Nitra River basin. The fifth part is focused on the assessment of changes in surface and groundwater quality during the drought periods within the pilot area. Finally, the results are summarized and interpreted, and rounded off with an outlook to future research.

This book presents the impact of climate change on Mount Baker glaciers, USA, and the rivers surrounding them. Glaciers are natural reservoirs that yield their resource primarily on warm dry summer days when other sources are at their lowest yield. This natural tempering of drought conditions will be reduced as they retreat. Mount Baker, a volcano in the Cascades of Washington, is currently host to 12 principal glaciers with an area of 36.8 km2. The glaciers yield 125 million cubic meters of water each summer that is a resource for salmon, irrigation and hydropower to the Nooksack River and Baker River watersheds. Recent rapid retreat of all 22 glaciers is altering the runoff from the glaciers, impacting both the discharge and temperature of the Nooksack and Baker River. Over the last 30 years we have spent 270 nights camped on the mountain conducting 10,500 observations of snow depth and melt rate on Mount Baker. This data combined with observations of terminus change, area change and glacier runoff over the same 30 years allow an unusually comprehensive story to be told of the effects of climate change to Mount Baker Glaciers and the rivers that drain them.

Mineral scale deposits, corrosion, suspended matter, and microbiological growth are factors that must be controlled in industrial water systems. Research on understanding the mechanisms of these problems has attracted considerable attention in the past three decades as has progress concerning water treatment additives to ameliorate these concerns. The Science and Technology of Industrial Water Treatment provides a comprehensive discussion on the topic from specialists in industry and academia. The book begins with an overview of water chemistry and covers the characteristics of commonly encountered mineral scales. It addresses the formation and control of different scales in various systems and examines new developments in membrane-based separation processes. Next, it provides a detailed account on the operational challenges of reverse osmosis systems and scale control in thermal distillation processes. The text explores corrosion control in cooling, boiler, geothermal, and desalination systems and it discusses the interactions of polyelectrolytes with suspended matter. Includes coverage of a range of bacterial species, including Legionella The book examines bacterial species commonly encountered in water supplies, the mechanisms of biofouling, approaches to control it, and criteria for selecting biocides for water treatment applications. An entire chapter is devoted to Legionella in water systems. Contributors describe various analytical techniques for identifying mineral scales and deposits. They also examine applications of polymers for treating industrial and wastewater systems and give an account of analytical approaches for monitoring various operational parameters and chemicals used to treat industrial water systems. A valuable addition to the library of academic researchers, this volume will also prove useful to those working not only in the water treatment industry, but also to those in petroleum, textiles, pharmaceuticals, and other areas where purity processes are a significant concern.

This book seeks to provide a comprehensive reconstruction of the 1667 Dalmatia earthquake phenomenon on the basis of eyewitness testimony. At the same time, one of the distinctive features of this book is that the earthquake observations are treated and arranged in time and space so as to provide earthquake data on the macroseismic intensity, which might be used in seismic hazard and risk studies. On April 6, 1667 a devastating earthquake struck the southernmost region of Dalmatia (Croatia). Most of the affected area at that time belonged to the independent Republic of Ragusa, the capital of which was the town of Ragusa, today Dubrovnik. The 1667 earthquake left behind a lasting scar on the history and life of the Republic, as it was the catalyst of a serious financial crisis. Both the economic and more general consequences of this earthquake have been discussed in historiographical and seismological essays in late 20th-century works. This book seeks to provide a comprehensive reconstruction of the 1667 Dalmatia earthquake phenomenon on the basis of eyewitness testimony. At the same time, one of the distinctive features of this book is that the earthquake observations are treated and arranged in time and space so as to provide earthquake data on the macroseismic intensity, which might be used in seismic hazard and risk studies. The book is also intended as an extensive case history, which allows the author to include some guidelines on how to approach the study of a past earthquake and proceed to its full seismological interpretation. In this respect, a unique feature of the book is the comprehensive and detailed analysis of the original documentary sources in their proper context, effectively combining the interpretative approaches of history and seismology.

The key highlights of the book include an innovative rainfall classification methodology based on stormwater quality to support the planning and design of stormwater treatment systems. Additionally, this book provides a practical approach to effective stormwater treatment design and development of a methodology for rainfall selection to optimize stormwater treatment based on both its quality and quantity. The case study presented in this book evaluates how pollutant buildup on urban surfaces and stormwater runoff quality varies with a range of catchment characteristics based on different rainfall types. The information presented will be of particular interest to practitioners such as stormwater-treatment designers, urban planners and hydrologic and stormwater-quality model developers since the outcomes presented provide practical approaches to and recommendations for urban stormwater-quality improvement. Readers will benefit from a state-of-the-art critical review of literature on urban stormwater quality, an in-depth discussion on stormwater-quality processes providing guidance for engineering practice such as stormwater treatment design and model development, a comprehensive overview on the application of multivariate data analysis techniques and a paradigm of the integrated use of commercial models and mathematical equations to undertake a comprehensive, urban stormwater-quality investigation.

The main objective of the Water Framework Directive in the European countries is to achieve a "good status" of all the water bodies, in the integrated management of river basins. In order to assess the impact of improvement measures, water quality models are necessary. During the previous decades the progress in computer technology and computational methods has supported the development of advanced mathematical models for pollutant transport in rivers and streams. This book is intended to provide the fundamental knowledge needed for a deeper understanding of these models and the development of new ones, which will fulfil future quality requirements in water resources management. This book focuses on the fundamentals of computational techniques required in water quality modelling. Advection, dispersion and concentrated sources or sinks of contaminants lead to the formulation of the fundamental differential equation of pollutant transport. Its integration, according to appropriate initial and boundary conditions and with the knowledge of the velocity field, allows for pollutant behaviour to be assessed in the entire water body. An analytical integration is convenient only in one-dimensional approach with considerable simplification. Integration in the numerical field is useful for taking into account particular aspects of water body and pollutants. To ensure their reliability, the models require accurate calibration and validation, based on proper data, taken from direct measurements. In addition, sensitivity and uncertainty analysis are also of utmost importance. All the above items are discussed in detail in the 21 chapters of the book, which is written in a didactic form for professionals and students.

This book takes an in-depth look at the theory and methods inherent in the tracing of riverine sediments. Examined tracers include multi-elemental concentration data, fallout radionuclides (e.g., 210Pb, 137Cs, 7Be), radiogenic isotopes (particularly those of Pb, Sr, and Nd), and novel ("non-traditional") stable isotopes (e.g., Cd, Cu, Hg, and Zn), the latter of which owe their application to recent advances in analytical chemistry. The intended goal is not to replace more 'traditional' analyses of the riverine sediment system, but to show how tracer/fingerprinting studies can be used to gain insights into system functions that would not otherwise be possible. The text, then, provides researchers and catchment managers with a summary of the strengths and limitations of the examined techniques in terms of their temporal and spatial resolution, data requirements, and the uncertainties in the generated results. The use of environmental tracers has increased significantly during the past decade because it has become clear that documentation of sediment and sediment-associated contaminant provenance and dispersal is essential to mitigate their potentially harmful effects on aquatic ecosystems. Moreover, the use of monitoring programs to determine the source of sediments to a water body has proven to be a costly, labor intensive, long-term process with a spatial resolution that is limited by the number of monitoring sites that can be effectively maintained. Alternative approaches, including the identification and analysis of eroded upland areas and the use of distributed modeling routines also have proven problematic. The application of tracers within riverine environments has evolved such that they focus on sediments from two general sources: upland areas and specific, localized, anthropogenic point sources. Of particular importance to the former is the development of geochemical fingerprinting methods that quantify sediment provenance (and to a much lesser degree, sediment-associated contaminants) at the catchment scale. These methods have largely developed independently of the use of tracers to document the source and dispersal pathways of contaminated particles from point-sources of anthropogenic pollution at the reach- to river corridor-scale. Future studies are likely to begin merging the strengths of both approaches while relying on multiple tracer types to address management and regulatory issues, particularly within the context of the rapidly developing field of environmental forensics.

Metrology and its applications e.g. in chemical or food analysis or in environmental monitoring are entering our daily life. This book provides a basic overview over the relevant metrological concepts like traceability, ISO uncertainties or cause-and-effect diagrams. The applications described in great detail range from progression-of-error type evaluation of the measurement uncertainty budget to complex applications like pH measurement or speciation calculations for aqueous solutions. The consequences of a measurement uncertainty concept for chemical data are outlined for geochemical modeling applied to transport in the subsurface and to nuclear waste disposal. Special sections deal with the deficits of existing thermodynamic data for these applications and with the current position of chemical metrology in respect to other quality assurance measures, e.g. ISO 900x, GLP, European and U.S.-American standards.

The Danube River Basin is shared by 19 countries and there is no river basin in the world shared by so many nations. Europe's second largest river basin with a total 2 area of about 800,000 km is also home to 83 million people of different cultures, languages and historical backgrounds. Management of common water sources and overcoming dif?culties caused by droughts and ?oods requires co-operation between the countries. In 1971 these c- mon interests stimulated the hydrologists of - at that time - eight Danube countries to begin regional co- operation in the framework of the International Hydrological Decade of UNESCO. The result of this research was The Hydrological Monograph of the Danube and its Catchment, which was published in 1986. Since 1975 this co-operation has continued under the umbrella of the International Hydrological Programme (IHP) of UNESCO. In the past 20 years political turbulence has caused an increase in the number of countries, making the co-operation dif?cult at times.

The remote mountain loch of Lochnagar is one of the most studied freshwater bodies in Europe. This book brings together knowledge gained over two decades of multi-disciplinary scientific study, with the results of lake sediment research covering millennia, to show how the loch has developed both naturally and as a result of human impact. Particular emphasis is placed on how this fragile ecosystem, and others like it, may be affected by future climate change.

This newly-translated book takes the reader from the basic principles and conservation laws of hydrodynamics to the description of general atmospheric circulation. Among the topics covered are the Kelvin, Ertel and Rossby-Obukhov invariants, quasi-geostrophic equation, thermal wind, singular Helmholtz vortices, derivation of the Navier-Stokes equation, Kolmogorov's flow, hydrodynamic stability, and geophysical boundary layers. Generalizing V. Arnold's approach to hydrodynamics, the author ingeniously brings in an analogy of Coriolis forces acting on fluid with motion of the Euler heavy top and shows how this is used in the analysis of general atmospheric circulation. This book is based on popular graduate and undergraduate courses given by F.V.Dolzhansky at the Moscow Institute of Physics and Technology, and is the result of the author's highly acclaimed work in Moscow's Laboratory of Geophysical Hydrodynamics. Each chapter is full of examples and figures, exercises and hints, motivating and illustrating both theoretical and experimental results. The exposition is comprehensive yet user-friendly in engaging and exploring the broad range of topics for students and researchers in mathematics, physics, meteorology and engineering.
