Hydrometry is concerned with the measurements of all the variables in the hydrological (water) cycle and hydrological information is therefore necessary for the practice of efficient water management. Water will be a major issue as the world enters the third millennium where more than one quarter of its population still do not have safe drinking water. An increasing demand is therefore placed on hydrometry to provide the essential hydrometric information in order that the world's water resources may be managed more efficiently. The aim of this second edition is to continue the success of the first edition by including new chapters on weather radar, remote sensing, groundwater and tree ring analysis, important in extending hydrometric records. Chapters of the first edition have been brought up to date as necessary in accordance with new technology and care has been taken to bridge the gap between past methods in hydrometry. The book therefore provides an invaluable guide to managers as well as field personnel who have operation and decision making roles in water management. Contents: Flow measurement; Instrumentation; Long river records; Precipitation measuring radar; Satellite remote sensing; Groundwater; Tree ring analysis; Transmission of hydrometric data by satellite; Maximizing the utility of river flow data; Hydrometric data processing; Uncertainties and Measuring up to water resources assessment.

Rivers and the ecosystems they support have always captivated humans, leading curious scientists to broaden our understanding with ongoing research. In Explorer's Guide to Rivers and Streams, Dr. Ryan Utz (Chatham University) presents a broad scientific understanding of rivers, streams, and the animals that reside within them, written accessibly for a general audience. Topics range from what causes river flows to rise and fall to the ecology of riverine fishes. Kayakers, anglers, and hikers alike will find many tools within Explorer's Guide to Rivers and Streams to deepen their understanding of their favorite waterway.

Drylands are usually characterised by strong climatic contrasts with rivers suffering seasonal drought and occasional torrential rains. Drylands produce a characteristic balance of hillslope and channel processes that give dryland rivers their special features. The most obvious and important property of most dryland rivers is that flow is ephemeral. Hence the relative importance of many fluvial processes differs considerably from more humid regions. Although these characteristics are not unique to dryland rivers, they share many attributes that place them outside the normal range of temperate rivers and merit separate study.

Dryland Rivers is the first text to focus on dryland channel networks and processes and presents a historical framework for research, discusses examples of current studies and evaluates contemporary modelling approaches. Emphasis is on the Mediterranean region, with comparisons to other dryland regimes, with differing degrees of aridity, and with seasonality that may differ from the Mediterranean regime of wet winters and dry summers.

Dryland Rivers is a vital text for water engineers, environmental consultants, and researchers in geomorphology or semi-arid environments. It will be an invaluable reference to postgraduate students and undergraduates at level 2 and 3, especially those focused on dryland environments.

Integrated Water Management (IWM) deals with the planning and management of water resources by integrating the different issues involved, including ecological, economic, technical legislative, and transboundary. This book offers a general framework for IWM. It includes both the different environmental problems that affect the very different ecosystems and the main methodologies able to face the problem of IWM.

At the present time, the deepening of our understanding about the nature of extreme and catastrophic natural and man-induced events, in particular hydrologic ones, becomes very topical. This book addresses the development of advanced methods for the prediction, the estimation of occurrence probabilities and the risk related to extreme hydrological events. Reduction of the vulnerability of social, economic, and engineering systems to extreme hydrologic events and the decrease of their effects on such systems is also being discussed in this book.

Dealing with these problems needs further refining of existing tools for the prediction and forecasting of extreme events. It can be done essentially through revealing mechanisms of their generation and with the use of new approaches and methodologies in related branches of statistical- and physics based hydrology.

The following topics are considered in this book:

1) Basin case studies on extreme hydrological events

2) Probabilistic estimation in flood studies

3) Ice-induced floods

4) River low flows, climatic conditions and environmental issues

5) Risk assessment and management for floods, low water events, and damage vulnerability issues.

Water is newsworthy: there is, or will be, a world water crisis. Aggravated by climate change, we are approaching the limits of human exploitation of freshwater resources, notably in growing essential food. The complexities and uncertainties associated with improving our management of fresh water take the potential remedies out of the hands of simple, local, hard engineering and into much larger units - the basin, the ecosystem and the global context, and also require longer term perspectives. The Third Edition follows the same structure as its predecessors, presenting the historical and scientific backgrounds to land-water interactions and establishing the links with development processes and policies. Throughout, its two major messages are that our new philosophy should be one of 'humans in the ecosystem' and that the guidance from science, being uncertain and contested, must be operationalized in a participatory system of governance based on participation. Following a review of progress towards these elements in the developed world, the international case studies update the situation in the developing world following the Millennium Development Goals, our new emphasis on poverty and on global food supplies. This book covers the multitude of scientific research findings, development of 'tools' and spatial/temporal scale challenges which have emerged in the last decade. Tensions are highlighted in the current and future role of large dams, country studies are retained (and considerably updated) and development contexts are explored in greater depth as a dividing line in capacity to cope with land and water stress. "Technical issues" have been expanded to cover major droughts, environmental flows and the restoration of rivers and wetlands. A separate chapter picks up these themes under terms of their relationship with uncertainty and the widespread perception that a new ethos of adaptive management is needed in the water sector. For students of geography, environmental science, hydrology, and development studies this innovative edition provides a reasoned, academic basis of evidence for sustainable, adaptive management of rivers and related large-scale ecosystems using more than 600 new sources. It will also prove invaluable for lecturers and practitioners.

The problems afflicting the Aral Sea and its environs as a result of the overuse and abuse of the rivers flowing into it are well documented. Until now, however, it was difficult to hear the voices of those responsible for actually managing those waters. This volume reproduces the proceedings of an Advanced Research Workshop held in Bishkek, which brought together all the most senior water resource managers in Central Asia, from Ministers to local experts and eminent academics. It describes, from the practitionera (TM)s perspective, the problems encountered in the regiona (TM)s efforts to implement integrated water resources management, and solutions that have been put in place in order to address these.

The book sets out the approaches taken by each basin state, by way of the institutional, legal and financial frameworks adopted by them. It details the management practices that have been utilised in order both to surmount potential inter-state conflicts arising from water use disagreements and to make the best use of the available water, and it provides practical examples demonstrating how IWRM has been implemented at more local levels. Ultimately, it conveys the strong spirit of collaboration that drives water management in the five newly independent states.

This book focuses on how hydrogeophysical methods can be applied to solve problems facing environmental engineers, geophysicists, agronomists, hydrologists, soil scientists and hydrogeologists. We present applications of hydrogeophysical methods to the understanding of hydrological processes and environmental problems dealing with the flow of water and the transport of solutes and contaminants. The majority of the book is organized as a series of process-driven chapters. Areas covered include: infiltration and solute transport processes, biogeochemical functioning of soil-water systems, coastal groundwater interactions, cold region hydrology, engineered barriers & landfill processes. In addition, the book offers insight into the development of new data fusion methodologies, of value to many hydrogeophysical investigations, and provides an account how the rapidly developing self-potential technique an give valuable information about water fluxes and hydrochemical states..

Environmental isotope and nuclear techniques provide unmatched insights into the processes governing the water cycle and its variability under past and present climates. This monograph is recommended to advanced students and specialists and presents historical perspective, state of the art applications and new developments of isotopes in hydrology, environmental disciplines and climate change studies.

The spectrum of isotope applications addressed in this monograph ranges from the assessment of groundwater resources in terms of recharge and flow regime, identification of palaeogroundwater, water balance of river basins and lakes, to studies of the past and present global environmental and climate changes. The contributions are written by renowned specialists in the various application fields.

The challenges that the world's running water systems now face have never been more numerous or acute; at the same time, these complex habitats remain absolutely crucial to human wellbeing and future survival. If rivers can ever be anything like sustainable, ecology needs to take its place as an equal among the physical sciences such as hydrology and geomorphology. A real understanding of the natural history and ecology of running waters must now be brought even more prominently into river management. The primary purpose of this textbook is to provide the up-to-date overview that students and practitioners will require to achieve this aim. The book's unifying focus is on rivers and streams as ecosystems in which the particular identity of organisms is not the main emphasis but rather the processes in which they are involved - specifically energy flow and the cycling of materials. It builds on the physicochemical foundations of the habitat templet and explores the diversity and adaptations of the biota, progressing from the population and community ecology of organisms and linking them to ecosystem processes and services in the wider biosphere via the complexities of species interactions and food webs. These include water quality and patterns of river discharge, as well as aesthetics, waste disposal, and environmental health. While the book is not primarily focused on application per se, each chapter addresses how humans affect rivers and, in turn, are affected by them. A final, future-oriented chapter identifies key strategic areas and sets a roadmap for integrating knowledge of natural history and ecology into policy and management. The Biology and Ecology of Streams and Rivers is an accessible text suitable for both senior undergraduate and graduate students taking courses in both lotic and general ecology as well as more established researchers, practitioners, managers, and conservationists requiring a concise and contemporary overview of running waters.

Only in Australasia can the effect of technological societies on river systems be truly analysed and this unique, accessible book covers key issues in river management from a geomorphological perspective.
Australia and New Zealand were colonised only 200 years ago by central bureaucratic administrations. For the whole period of European settlement most river management activities have been carried out by government agencies and the record of their activities is relatively complete. These countries therefore provide good case studies for the impact of technological societies on river systems, having transformed their rivers in a short time from their 'natural' into a heavily managed condition.
Geomorphology provides the scientific basis for much of our understanding of river behaviour and geomorphologists are now actively involved in the management process. This book provides a collection of case studies, the first to be produced to date, which describe the management of rivers covering issues of environmental flow, stream condition, mining and extractive activities, river channel change, river stabilisation, river regulation and urban streams.
The book will prove invaluable to geomorphologists, river engineers, stream ecologists, river managers, and environmental impact assessors involved in river management and restoration.

Karst Hydrogeology, Geomorphology and Caves A Comprehensive Resource Covering All Aspects of Karst Hydrogeology, Geomorphology, and Caves This essential book covers all physical, chemical, and geological aspects of karst science. It reviews current knowledge on hydrogeology, geomorphology and caves in karst, based on the vast existing literature and investigations carried out by the authors worldwide. The different topics are profusely illustrated with color figures and images from all continents and climates, showing the scientific and aesthetic appeal of karst environments. The book covers in a systematic way the significant features of karst rocks, the chemistry and kinetics of their dissolution, the rate and distribution of karst denudation, the unique hydrogeology of karst terrains, the landforms endemic to karst, the morphology of caves and their diverse sedimentary records, and the multiple processes that lead to the formation of underground voids. Overall, the work reflects the increasing recognition of karst as a fundamental part of the Earth's dynamic systems, and helps readers understand this multidisciplinary field from a holistic and nuts-and-bolts perspective. Some of the ideas discussed within the book include: How karst is gaining importance for human development, because of its valuable resources (groundwater) and associated environmental problems (impacts and hazards) The enormous technological developments achieved in recent years Recent major breakthroughs in the field and their influence on other scientific disciplines The central role played by karst science for understanding and mitigating global environmental issues (global warming, depletion of resources, human-induced hazards) For all scientists working in karst, and for students and lecturers of karst-related programs, this book serves as a valuable all-in-one source. It is also a valuable resource for professional hydrogeologists, the petroleum industry, environmental geologists, and of course speleologists, the last true geographic explorers in the world.

Database management tools providing techniques for the monitoring and storing of information are described.

During the 20th century, lake research has become an internationally recognised field of scientific activity, improving our understanding on physical, chemical and biological processes, on fresh water ecology, and water resources among others. The interdisciplinary approaches mainly developed in historical research, as performed by archaeologists and earth scientists, to reconstruct the environmental and climate history of the continents, of human settlements and culture, and to evaluate human impact on the local and global environments. The Geological Society of Switzerland publishes in this volume a selected number of contributions presented during a scientific conference on "Lake Systems from Ice Age to Industrial Time" at Yverdon from 17 to 20 October 2001.

Developments in the modelling of sediment transport in rivers and the interactions with the river--bed have been remarkable over the last two decades. This progress has increased the understanding of the nature of turbulence, and the ability to replicate mathematically simple flow--particle interactions which can be observed experimentally. In addition, quite elegant models of stratigraphic complexes have evolved because of the growing computational power available to scientists. As always, additional knowledge has raised even more intriguing questions and the quest for explanation of phenomena has led to increased specialisation. Therefore, there are few fluid dynamicists or sedimentologists who can successfully span the two disciplines. The intention of this book is to assist various specialists on keeping abreast of current developments in related areas. The book initially focuses on hydrodynamics of turbulent flow, followed by basic two and three--dimensional flow through straight and curved channels and the flow over bed topography. This is then followed by a consideration of initial motion, sediment transport and particle sorting. The potential for modelling fluidsediment interactions is provided at the end of the first section. Linking chapters then follow, considering the preservation potential of fluvial bedforms in the stratigraphic record and the basic variety of channel morphology recognised in sedimentary studies. Subsequent chapters consider reconstructing hydraulic process and fluvial morphology from stratigraphy; the influence of bedform and depositional controls on packing of economically important sedimentary rocks; and recent advances in modelling subsurface fluvial stratigraphy. A final chapter provides a brief view of future perspectives. The objective of this volume is to review recent advances made by geologists and hydrodynamicists in an accessible manner and to promote an increased and fruitful dialogue between sedimentary geologists, geomorphologists and hydrodynamicists.

Geomorphology and Groundwater is an up--to--the--minute collection dealing with the overlap between geomorphology and hydrogeology. These two disciplines have much to offer each other in several fields such as river groundwater interactions, the location and evolution of aquifers, karst and landform evolution. There is increasing realisation that groundwater plays an important role in many geomorphological processes and of the utility of geomorphological techniques and ideas in the analysis of groundwater systems. The authors contributing to this volume are drawn from a wide variety of backgrounds and include research geomorphologists, engineers and consulting hydrogeologists. Much of the work reported here applies to or has immediate applications to such environmental problems as arid--zone water supply, groundwater pollution, wetland conservation, fisheries management and landscape protection. As such this book will be of value not only to researchers in the respective fields, but to all those interested in groundwater--related environmental issues.

This book contains a selection of papers from a NATO Advanced Research Workshop entitled "Stochastic models of hydrological processes and their applications to problems of environmental preservation" convened in Moscow over the period 23-27 November 1998. The Workshop was unique in providing the first opportunity for over a decade for countries of the Russian Federation to interact with other countries across the world to discuss hydrological science issues relevant to environmental management. The contrasting schools of thought within the Russian Federation and with other countries proved a fascinating and valuable experience for those fortunate enough to attend. The scientific content of the Workshop was motivated by a number of concerns. Water is a key natural resource whose modelling and management is made complex by its inherent spatial unevenness and time variability. Traditional methods for investigating hydrological processes in nature employ stochastic modelling and forecasting. However these are not well developed with regard to (i) representing the characteristics of hydrological regimes, and (ii) investigating the influence of water factors on processes which arise in biological systems and those involving hydrochemical, geophysical and other processes.

Stephen Trudgill presents an internationally authored research-level text, aimed at providing a synopsis of developments in solute modelling in catchment ecosystems over the last ten years. The volume includes particular advances in solute modelling, especially at the catchment scale, emphasising the influences of weathering, ecosystem processes and hydrological processes as well as the application of models and modelling principles. The intended audience for the book is research scientists in cognate fields and postgraduate research workers, although it is especially aimed at those interested in catchment systems. It will also enable specialists to grasp the essentials of topics outside their own field. The book will be of use in a management context as successful water quality management actions are often dependent upon the predictive success of models. It will also show how models can be used to assess the sensitivity of solute production to environmental change and human influence, such as land use change and variation in atmospheric inputs, focussing upon surface catchments rather than groundwater and soil solutes.

Palaeohydrological research is a comparatively recent development. However, research undertaken has already demonstrated a significant multidisciplinary impact and shown how palaeohydrology can provide an important contribution to the study of global change. Although a considerable amount of exciting palaeohydrological research has been applied to particular areas, there has not previously been a systematic approach to research into the palaeohydrology of the Earth's surface. It was for this reason that a Commission was established by INQUA in 1991 on Global Continental Palaeohydrology. This volume provides the background to that exciting international research project and has been written to provide a basis for understanding the current state of research into the palaeohydrology of the land surface of the Earth. It therefore gives a summary of the work achieved to date and of the research investigations currently taking place, together with an indication of the way in which palaeohydrological research relates to other global research programmes.

Provides an introduction to the chemistry of the solid-water interface, progressing from the simple to more complex and applied. Discusses the important interfaces in natural systems, especially geochemistry, in natural waters, soils and sediments. The processes occurring at mineral-water, particle-water and organism-water interfaces play critical roles in regulating the composition and ecology of oceans and fresh waters, the development of soils and plant nutrient's supply, preserving the integrity of water repositories and in such applications as water technology and corrosion science.

Lake Issyk-Kul is a closed lake located in the Tien Shan mountain belt of the Republic of Kyrgyzstan. It is the world's fifth deepest lake (668 m) and the second largest high altitude lake in the world (1607 m above sea level). The lake is affected by several environmental threats of both anthropogenic and natural origin: decline of the lake level resulting in progressively increasing salinity, incomplete vertical water exchange, and risk of contamination by past and present industrial activity.
Although the lake has been intensively studied, the information is only available in unpublished reports or local scientific journals. This book presents for the first time to an international audience the main physical, chemical, biological and geological characteristics of the lake, the fruits of many years of observations, complemented by recent results of international projects. Case studies of similar problems in other parts of the world are presented, together with ethical aspects of the environmental protection of the lake.

Riverscapes are the main arteries of the world's largest cities, and have, for millennia, been the lifeblood of the urban communities that have developed around them. These human settlements - given life through the space of the local waterscape - soon developed into ritualised spaces that sought to harness the dynamism of the watercourse and create the local architectural landscape. Theorised via a sophisticated understanding of history, space, culture, and ecology, this collection of wonderful and deliberately wide-ranging case studies, from Early Modern Italy to the contemporary Bengal Delta, investigates the culture of human interaction with rivers and the nature of urban topography. Riverine explores the ways in which architecture and urban planning have imbued cultural landscapes with ritual and structural meaning.
