"I read this wide-ranging and thoughtful book while sitting on the banks of the Ganges near Varanasi-it's a river already badly polluted, and now threatened by the melting of the loss of the glaciers at its source to global warming. Four hundred million people depend on it, and there's no backup plan. As Steven Solomon makes clear, the same is true the world over; this volume will give you the background to understand the forces that will drive much of 21st century history." -Bill McKibben In Water, esteemed journalist Steven Solomon describes a terrifying-and all too real-world in which access to fresh water has replaced oil as the primary cause of global conflicts that increasingly emanate from drought-ridden, overpopulated areas of the world. Meticulously researched and undeniably prescient, Water is a stunningly clear-eyed action statement on what Robert F Kennedy, Jr. calls "the biggest environmental and political challenge of our time."

Coverage includes shoreland buffer installation, fisheries management, reducing nuisance algal growth, controlling exotic aquatic plants, lakeside wastewater treatment systems, small scale dredging, and more.

This book demonstrates the role of dominant ecological factors on the organisms of running water and the functioning of the ecosystem, as well as the consequences of human activity. It provides vision of certain rivers and streams that represent various types of European watercourses.

Deterministic Methods in Systems Hydrology presents the basic theory underlying the multitude of parameter-rich models which dominate the hydrological literature. Its objectives are to introduce the elements of systems science as applied to hydrological problems; to present flood prediction and flood routing as problems in linear systems theory, clarifying the basic assumptions and evaluating their accuracy; and to review and to evaluate some deterministic models of components of the hydrological cycle, with a view to assembling the most appropriate model of catchment response, for a particular problem in applied hydrology. The material is developed in two parts: the first four chapters present the systems viewpoint, the nature of hydrological systems, some systems mathematics and their application to direct storm runoff. The final four chapters cover linear conceptual models of direct runoff, the fitting of conceptual models to data, simple models of subsurface flow and non-linear deterministic models.

The large lakes of the East African Rift Valley are among the oldest on Earth, and are vital resources for the people of their basins. They are unique among the large lakes of the world in terms of their sensitivity to climatic change, rich and diverse populations of endemic species, circulation dynamics and water-column chemistry, and long, continuous records of past climatic change. A comprehensive study of the large African lakes is long overdue. The scientific justification for such an effort is noted in the previous paragraph and is illustrated in great detail in this volume. Societal need for the sustainable utilization of these lakes offers an even more compelling reason for examination of biological food webs, water quality, and past climate variability in East Africa. The lakes provide the most important source of protein for the people of the African Rift Valley, and fish populations are shifting dramatically in response to fishing pressure, introduction of exotic species, land use impact on water quality, and perhaps climatic change. Current estimates of primary productivity, the underpinning of the food resource, are extremely crude and based on only a few spot measurements.

Modeling hydrologic changes and predicting their impact on watersheds is a dominant concern for hydrologists and other water resource professionals, civil and environmental engineers, and urban and regional planners. As such changes continue, it becomes more essential to have the most up-to-date tools with which to perform the proper analyses and modeling of the complex ecology, morphology, and physical processes that occur within watersheds. An application-oriented text, Modeling Hydrologic Change: Statistical Methods provides a step-by-step presentation of modeling procedures to help you properly analyze and model real-world data.

The text addresses modeling systems where change has affected data that will be used to calibrate and test models of the system. The use of actual hydrologic data will help you learn how to handle the vagaries of real-world hydrologic-change data. All four elements of the modeling process are discussed: conceptualization, formulation, calibration, and verification. Although the book is oriented towards the statistical aspects of modeling, a strong background in statistics is not required. The statistical and modeling methods discussed here will be of value to all disciplines involved in modeling change. With approximately 100 illustrations, Modeling Hydrologic Change will equip you with an understanding with which to perform the proper analyses and modeling of the complex processes that occur across various disciplines.

This is the fifth and last volume representing the proceedings of the International Conference on Water Resources Management in Arid Regions held March 23rd-27th 2002 in Kuwait. This book discusses major aspects of hydrology and water resources. It presents papers on important aspects of surface water and groundwater hydrology, including drought tendencies, regional flood frequency analysis, urban storm drainage with curb-opening inlets, isotopic investigations for lakes, hydrologic and sediment transport modeling, groundwater exploration using remote sensing and GIS, origin and recharge rates of alluvial ground waters, stormwater and groundwater management, and considerations for stochastic finite element in geostatistics and modeling. Papers on water quality supplement the discussion.

Flood disasters continue to occur in many countries in the world and cause tremendous casualties and property damage. To mitigate the effects of floods, a range of structural and non-structural measures have been employed including dykes, channelling, flood-proofing property, land-use regulation and flood warning schemes. Such schemes can include the use of Artificial Neural Networks (ANN) for modelling the rainfall run-off process as it is a quick and flexible approach which gives very promising results. However, the inability of ANN to extrapolate beyond the limits of the training range is a serious limitation of the method, and this book examines ways of side-stepping or solving this complex issue.

This book applies the 'ecosystem services' framework to coastal environments, showing how it could facilitate an adaptive management strategy. The contributors describe a decision support system (DSS) based on the 3 Ps - pluralism, pragmatism and precaution - that leads to a more flexible, 'learn by doing' approach to the stewardship of coastal environments. The book lays out a "Balance Sheets Approach" to formatting, interrogating and presenting data and findings. The opening chapter defines coastal zones, their characteristics and natural resources, and describes their complex and dynamic nature. The chapter shows that large-scale trends and pressures have led to a global loss of 50% of marshes, leading to significant declines in biodiversity and habitat. Part I presents a conceptual framework, describes natural science techniques for coastal and shelf modeling, and describes valuation of ecosystem services. Part II outlines practical ecosystem indicators for coastal and marine ecosystem services, reviews literature on valuation of coastal and marine ecosystem services, explores scenarios, outlines marine and coastal ecosystem services data and offers tools for incorporating data into decision-making. PART III offers case studies including one linking the ecosystem services of Marine Protected Areas to benefits in human wellbeing; and another on valuing blue carbon captured by oceans and coastal ecosystems. Also included are a study of managed realignments and the English coastline and their value estimate transferability; and studies of the impact of jellyfish blooms on recreation in the UK and on fisheries in Italy.

The book presents improved equations for monthly water resources models, in particular for interception and transpiration. Most of the existing monthly models do not make a distinction between interception and transipiration, while this distinction is very important for management purposes. Interception is direct feedback to the atmosphere, important to sustain rainfall. Transpiration is a good indicator for plant growth and biomass production. This distinction also contributes to the estimation of recharge and therewith of runoff.;The derivations are based on the Markov theory for the occurrence of rain-days. The methodology can be used on the basis of an analysis of a few time series of daily data, at a spatial scale of 300km and not necessarily of the same period as the monthly data. Zimbabwe served as the case study, but derived equations can be used worldwide as long as the relationship between the monthly rainfall and the mean number of rain-days can be established.

Effective management of a water well requires that the water well can meet a set of performance indicators. These can include criteria related to water quality, yield, economics and asset life. Water well deterioration due to fouling and corrosion impacts the ability of a well system to meet these criteria. Managing well deterioration processes involves understanding the nature of these processes and having in place water well maintenance strategies to deal with them. Managing water well deterioration fills a need within the literature for an academically based informative text that incorporates practical advice. The focus on a problem-oriented approach to diagnosing well deterioration makes the book a useful practical handbook. It integrates concepts from hydrogeology, hydrochemistry and microbiology to give a thorough understanding of water well deterioration processes. Scenarios have been developed to illustrate common causes of water well fouling. A feature of the book is the treatment of both corrossion and fouling issues in depth. Case studies selected from around the world are uses to illustrate approaches to the diagnosis and remediation of well deterioration. These scientifically orientated perspectives on water well deterioration are embedded within a management framework to provide a comprehensive approach to dealing with water well deterioration.

Calcium and magnesium are abundant in groundwater, but the role of groundwater as the essential source of these important nutrients is very often neglected. Hydrogeochemical studies have focused mainly on the distribution and behaviour of constituents that cause deterioration of water quality, such as: nitrate, nitrite or iron and manganese. Therefore, most recent books and papers concentrate mainly on these constituents and only a small number of papers describe the results of groundwater studies on other important water components such as calcium or magnesium. Calcium and magnesium are of great importance to human wellbeing and inadequate intake of either nutrient can impair health. The main objective of this book is to present a selection of studies on calcium and magnesium in groundwater and to highlight their importance for human health. The chapters in this book are written by hydrogeologists and hydrochemists as well as medical doctors and include: methods of investigation of calcium and magnesium in groundwaters, distribution and behaviour of calcium and magnesium in different aquifers, calcium and magnesium in bottled mineral and spring waters, and the significance of calcium and magnesium in waters for human health.

There has been an explosive growth of methods in recent years for learning (or estimating dependency) from data, where data refers to known samples that are combinations of inputs and corresponding outputs of a given physical system. The main subject addressed in this thesis is model induction from data for the simulation of hydrodynamic processes in the aquatic environment. Firstly, some currently popular artificial neural network architectures are introduced, and it is then argued that these devices can be regarded as domain knowledge incapsulators by applying the method to the generation of wave equations from hydraulic data and showing how the equations of numerical-hydraulic models can, in their turn, be recaptured using artificial neural networks.
The book also demonstrates how artificial neural networks can be used to generate numerical operators on non-structured grids for the simulation of hydrodynamic processes in two-dimensional flow systems and a methodology has been derived for developing generic hydrodynamic models using artificial neural network. The book also highlights one other model induction technique, namely that of support vector machine, as an emerging new method with a potential to provide more robust models.

Within the realm of the newly evolving discipline of environmental sciences, the stable-isotope methodology is being used to an ever-increasing extent, especially in the study of the water cycle and of paleo-climatology. This book introduces the rules of the game, by reviewing the natural variability of stable isotopes in the hydrosphere, describing the physico-chemical basis of isotope fractionation, and applying this knowledge to natural waters as they move through the hydrologic cycle from the ocean to the atmosphere, the biosphere and the lithosphere. There is a special focus on the processes at the surface-atmosphere and land-biosphere-atmosphere interfaces, since these are the sites of major changes in isotope composition. In response to the increasing awareness of our changing climate, a discussion on the global view of the changing water cycle, in the past and future, winds up the presentation.

The four volumes in this set cover major aspects of hydrology and water resources, including surface water hydrology, subsurface water hydrology, water quality hydrology, and water resources planning management. The books reflect the water resources technology as practised in India and the Indian subcontinent which should be of value to water resources professionals in the West. The books should be of interest to academicians, graduate students, practising engineers, water engineers, as well as water policy makers.

Readers will learn about acceptable data formats and representative model products. The last section of the book is devoted to the challenges of planning, deploying and maintaining coastal ocean observing systems. Readers will discover practical applications of ocean observations in diverse fields including natural resource conservation, commerce and recreation, safety and security, and climate change resiliency and adaptation. This volume will appeal to ocean engineers, oceanographers, commercial and recreational ocean data users, observing systems operators, and advanced undergraduate and graduate students in the field of ocean observing.

Environmental contamination in cold regions poses unique problems. It affects traditionally pristine areas and presents substantial operational difficulties. The extreme temperature range, soils and geology, the unique biological diversity, the freezing and thawing of pollutants, and the impact of human activities make environmental site assessment and remediation a challenging task.
Based on papers presented at an international workshop held in Anchorage, Alaska, Contaminant Hydrology: Cold Regions Modeling provides insight into areas such as:
· Problems of contaminant hydrology
· Strategies for development of cost effective amelioration procedures
· Basic guidelines for conducting groundwater modeling
· Feasibility and computer model studies
Appoximately 50% of the earth's land mass is frozen at some time during the annual cycle. While we know a lot about contaminant fate and transport in cold regions, we must gain a better understanding of the effects of contamination and predicting the effectiveness of remedial actions. Contaminant Hydrology: Cold Regions Modeling provides this knowledge, making it easier to choose cost-efficient and effective methods.

The efficient management of water supply becomes even more important in arid areas where supply is at best erratic. This book looks at a range of issues connected to urban and agricultural water use in the Sana'a Plain area, including engineering and logisical problems, environmental and climatic influences on groundwater, legal and political wrangles, economic considerations and options for waste water re-use.

The last decade has been a period of rapid advances in glacier hydrology and hydrochemistry. These have resulted from the application of new technologies to the direct observation of englacial and subglacial drainage systems via boreholes, from theoretical advances and from increased interactions between fieldworkers and modellers. This collection of papers captures the spirit of these advances highlighting new methodologies, the change in character of hydrological models from lumped conceptual models to physically based, distributed models, and the changing role of field studies in glacier hydrological investigations. Major themes identified in the book are: approaches to defining the structure of drainage systems in cold and temperate glaciers; investigations of the linkages between surface and subsurface components of these systems, and of hydraulic interactions between different elements of subglacial systems; seasonal changes in drainage system properties at local and glacier wide scales; controls on meltwater quality; the integration of field and modelling studies; and problems of scaling up results from studies of valley glaciers to the ice sheet scale.
