An important part of the risk management of natural hazards in mountain regions concerns the hazard assessment and the planning of protection measures in steep headwater catchments, i.e. torrent control and slope stabilization. Torrent processes in steep channels have their rightful place among the various alpine natural hazards and the corresponding control measures have a long tradition in the European alpine countries. In the planning and execution of such measures, professional experience has been of paramount importance. This experience was based primarily on observations made during and after hazardous events, as well as on regular field visits in the catchments of a steep headwater stream. Quantitative measurements, e.g. of the discharge and of the eroded and deposited solid materials, have been increasingly carried out only in the last decades. This set the basis to develop and improve quantitative methods to predict flow hydraulics, bedload transport and debris flows in torrent catchments. This publication presents an overview of methods to quantify channel processes in steep catchments. The understanding and the quantitative description of channel processes provides an essential basis for the planning of protection measures.
Biology and Management of Invasive Quagga and Zebra Mussels in the Western United States is a synthesis of the biology and management of invasive mussels from scientists and managers working on invasive quagga and zebra mussels in the western United States. Invasive dreissenid mussels have spread throughout southwestern United States at unprecedented speeds, and present a unique threat to native ecosystems. This book documents the efforts, both successful and unsuccessful, of individuals and agencies after dreissenid mussels invaded the West. Although the book is designed specifically for scientists and managers fighting invasive mussels in western waterbodies, it offers an opportunity for scientists and lake managers worldwide to compare successful strategies relevant to their unique situation. It includes guidance documents and protocols related to early detection, prevention, regulation, monitoring, and control of these invasive pests in the West. It compares quagga and zebra mussels in the western United States with those mussels colonizing the Great Lakes and European waters.
Lessons can be learnt from the past; from time to time it is useful for practitioners to look back over the historical developments of their science. Hydrogeology has developed from humble beginnings into the broad church of investigatory procedures which collectively form the modern-day hydrogeologist's tool box. Hydrogeology remains a branch of the over-arching science of geology and today provides analysis of the sub-surface part of the water cycle within a holistic approach to problem solving. The History of Hydrogeology, is a first attempt to bring the story of the evolution of the science of hydrogeology together from a country- or region-specific viewpoint. It does not cover history to the present day, nor does it deal with all countries involved in groundwater studies, but rather takes the story for specific key countries up and until about the period 1975 to 1980. This is when hydrogeology was still evolving and developing, and in some areas doing so quite rapidly. The book has been written not only for practitioners of hydrogeology and hydrology but also for teachers and students to see the context of the evolution of the science around the globe. The History of Hydrogeology will also be of interest to science historians and all those interested in the role that individuals, institutes and nations have played over the years in defining modern day studies of groundwater.
This outstanding reference book deals with effects of various agricultural practices on ground water quality and usage; and ground water management strategies for protection of ground water affected by agriculture.
Environmental stress caused by water continuously exposes buildings to microbial colonization. This is highly evident when both minor dampness and mass flooding occur. The text describes how microbiological corrosion of buildings and the structures and substances derived from these hazards are responsible for adverse health effects on people exposed to these contaminated environments. Microbiological Corrosion of Buildings: A Guide to Detection, Health Hazards, and Mitigation describes the key elements and methods for neutralising and removing microbiological contamination, and the operating algorithm for checking the effectiveness of preventative solutions. Ideal for construction engineers, microbiologists and professionals in the field. Features: Latest methods for detection of indoor microbial hazards Identifies the tools needed for natural, non-destructive and non-invasive methods of bio-corrosion removal Describes the social and health problems associated with exposure to microbiological hazards Provides case studies and examples of microorganisms responsible for microbial corrosion. 'Climate change and the associated adverse effects, such as floods and whirlwinds, make the problem of microbiological corrosion of buildings that generates health risks and economic losses on a global scale, the focus of science and technology. The monograph presents a complex problem of building bio-corrosion, that requires knowledge of the distant fields of microbiology and building technology, for the use of both scientists and practitioners. This pioneering work of an interdisciplinary nature harmoniously combines knowledge on specific microbiological issues relating to the process of bio-corrosion and the associated health risks with detailed issues of construction technology concerning the prevention of bio-corrosion and its removal. The authors succeeded in combining a very high scientific level in the monograph with an accessible and understandable presentation of complex problems. The extensive references, ranging from "classical" items from many years ago to the most recent articles presenting the state of the art in this field, are worth emphasising.' -Prof. Jacek Dutkiewicz, Ph.D., D.Sc., Institute of Rural Health in Lublin

Introduction to Urban Water Distribution comprises the core training material used in the Master of Science programme in Urban Water and Sanitation at IHE Delft Institute for Water Education. Participants in this programme are professionals working in the water and sanitation sector from over forty, predominantly developing, countries from all parts of the world. Outside this diverse audience, the most appropriate readers are those who know little or nothing about the subject. However, experts dealing with advanced problems can also use it as a refresher of their knowledge, as well as the teachers in this field may like to use some of the contents in their educational programmes. The general focus in the book is on understanding the steady-state hydraulics that forms the basis of hydraulic design and computer modelling applied in water distribution. The main purpose of the workshop problems and three computer exercises is to develop a temporal and spatial perception of the main hydraulic parameters in the system for given layout and demand scenarios. Furthermore, the book contains a detailed discussion on water demand, which is a fundamental element of any network analysis, and general principles of network construction, operation and maintenance. The book includes nearly 700 illustrations and the accompanying electronic materials contain all the spreadsheet applications and the network model files used in solving the workshop problems and computer exercises.
Nature-based solutions (NbS) are solutions inspired or supported by nature. They include ecosystem conservation and restoration measures, as well as the creation or enhancement of natural processes in man-made ecosystems, such as cities. Recent interest in NbS has emphasized their importance for urban water management and cities across the world have begun to experiment with them. Experiences from different contexts, however, are not adequately captured and understood. This book aims to address this gap by compiling case studies and reviews that explore NbS for urban water management from different regions and perspectives and highlight emerging challenges and opportunities for harnessing their potential.
The contingent valuation of water is one of the key components when wanting to implement proposals for integrated water management in mountain basins. Management of Hydrological Systems (MHS), is one of the great challenges that the Sustainable Development Goals (SDGs) currently demand. Mainly in mountain basins with fragile ecosystems that face strong pressures such as poverty, urban and population growth, low water supply and sanitation, and climate change. Management of Hydrological Systems aims for sustainable water management, through contingent water valuation, showing the reader in a didactic way the procedure to follow in mountain basins. This book offers a complete characterization of the main problems affecting this type of basin, as well as the detailed procedure of the contingent valuation of water, which directly involves users. As such, this work is offered in relation to this urgent need for practical guidance demanded by society (SDGs), and is based on practical and real examples, rather than theoretical constructions, from places where these issues have not been widely addressed. The text is recommended as a way forward, not only for water resource managers and decision- and policymakers but also for students and teachers who wish to implement this MHS guide.

Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world's population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.

The science-policy interface is critical to the design and implementation of water policies. In theory, scientists provide policy makers with robust facts and data that can help guide decision making, and lessons from the political economy of reforms can push scientific boundaries further to trigger further research for wise solutions. While evidence-based policy is obviously desirable, in practice such a connection is not always straightforward. Another assumption behind the science-policy gap is the discrepancy between scientists and policy makers in terms of culture, process, timing, language and expected outcome. This book tries to reconcile this discrepancy through a multi-stakeholder approach to authoring its different articles. This joint initiative between the OECD - particularly its Water Governance Initiative - and the International Water Resources Association seeks to provide a canvas for grounding water policy in science, and vice versa. The objective of this book, devoted to the OECD Principles on Water Governance, is to use the OECD Principles as a common thread across the articles to draw lessons from theoretical work and practical experiences in water governance reforms; but also to only feature papers authored by groups of diverse stakeholders from different institutional backgrounds. This book was originally published as a special issue of Water International.
This book covers the distribution, hydrochemistry and geophysics of the naturally occurring stable isotopes namely: hydrogen, oxygen and radioactive tritium, carbon and other cosmogenic and radiogenic isotopes of the uranium-thorium series, in the oceans and in atmosphere, the earth's surface and ground water. The use of environmental isotopes in the three main areas of natural waters is discussed: origin, dynamics and residence time in natural reservoirs. The origin of the hydrosphere is examined in the light of isotopic, new cosmochemical and recent theoretical results. The book will be of interest to scientists and researchers who use environmental isotopes in solving scientific and practical problems in hydrology, hydrogeology, oceanography, meteorology, hydrogeochemistry and cosmochemistry. Lecturers, students and postgraduates in these fields will also find it useful.
The 31 chapters provide a wealth of previously unpublished information, plus topic syntheses, for a wide range of ecological parameters. These include the physical driving forces that created and continue to shape the Everglades and patterns and processes of its flora and fauna. The book summarizes recent studies of the region's vegetation, alligators, wading birds, and endangered species such as the snail kite and Florida panther. This referee-reviewed volume is the product of collaboration among 58 international authors from 27 institutional affiliations over nearly five years. The book concludes with a synthesis of system-wide restoration hypotheses, as they apply to the Everglades, that represent the integration and a collective viewpoint from the preceding 30 chapters. Techniques and systems learned here can be applied to ecosystems around the world.
"The Global Water System in the Anthropocene "provides the platform to present global and regional perspectives of world-wide experiences on the responses of water management to global change in order to address issues such as variability in supply, increasing demands for water, environmental flows and land use change. It helps to build links between science and policy and practice in the area of water resources management and governance, relates institutional and technological innovations and identifies in which ways research can assist policy and practice in the field of sustainable freshwater management.Until the industrial revolution, human beings and their activities played an insignificant role influencing the dynamics of the Earth system, the sum of our planet s interacting physical, chemical, and biological processes. Today, humankind even exceeds nature in terms of changing the biosphere and affecting all other facets of Earth system functioning. A growing number of scientists argue that humanity has entered a new geological epoch that needs a corresponding name: the Anthropocene.Human activities impact the global water system as part of the Earth system and change the way water moves around the globe like never before. Thus, managing freshwater use wisely in the planetary water cycle has become a key challenge to reach global environmental sustainability."

Published in 1968: The author not only pioneered modern-style village surveys in both England and India, but also modern style urban surveys and studies in India. There he broke new ground in his remarkable first-hand researches on agricultural labour, village economics, depressed or "Untouchable" classes in town and country, and human and industrial relations in India's first steel town, Jamshedpur. In the text of this book we reproduce thirty-five of the author's papers - in whole, in part, or in summary.
This book includes selected papers presented at the international expert forum on "Mainstreaming Resilience and Disaster Risk Reduction in Education," held at the Asian Institute of Technology, Thailand on 1-2 December 2017. The journey towards disaster risk reduction and resilience requires the participation of a wide array of stakeholders ranging from academics to policymakers, to disaster managers. Given the multifaceted and interdependent nature of disasters, disaster risk reduction and resilience require a multidisciplinary problem-solving approach and evidence-based techniques from the natural, social, engineering, and other relevant sciences. Traditionally, hazard and disaster-related studies have been dominated by the engineering and social science fields. In this regard, the main purpose of this book is to capture the multidisciplinary and multisectoral nature of disaster risk reduction, and to gather existing data, research, conceptual work, and practical cases regarding risk reduction and its ties to sustainable development under a single "umbrella." Along with the sustainability aspect, the book also links disaster risk reduction with development, technology, governance, education, and climate change, and includes discussions on challenges, solutions, and best practices in the mainstreaming of disaster risk reduction.
Recent instances of bioinvasion, such as the emergence of the zebra mussel in the American Great Lakes, generated a demand among marine biologists and ecologists for groundbreaking new references that detail how organisms colonize hard substrates, and how to prevent damaging biomass concentrations. Marine Biofouling: Colonization Processes and Defenses is the English language version of a comprehensive work by eminent Russian scientist Alexander I. Railkin, who details the causes of vast biomass concentrations on submerged hard substrates. He also delivers a quantitative description of colonization processes and provides detailed models for preventing biofouling. This volume expounds on many topics rarely discussed in the frame of one book: types of hard substrate communities; comparison of hard and soft substrate communities; harm caused by micro- and macrofoulers; larval taxes and drift; mechanisms of settlement and attachment of microorganisms, invertebrates, ascidians and macroalgae; the impact of currents; protection from epibionts; industrial biofouling protection; successions on hard substrates; and the recovery of disturbed communities or the self-assembly of communities. The text includes much Russian-language research translated for the first time. Through a thorough examination of substrate organisms and an exploration of preventive methods, this monograph prepares those concerned with marine biology to help protect the self-purifying organisms that keep marine ecosystems healthy and productive.
Dyes are versatile compounds that have been successfully used in textile printing, rubber, cosmetics, plastic, pharmaceutical, and leather industries to color the products. Dye-using industries, particularly textile or printing industries are responsible for the generation of a great amount of colored wastewater that are polluting and threatening the environment. Many of these dyes are carcinogenic, mutagenic, and teratogenic, as well as harmful to human, aquatic life, and other living things and their elimination from wastewater is highly essential. Various approaches have been implemented in the efforts to mitigate the issue related to textile wastewater, such as adsorption, biological processes, advanced oxidation processes, membrane technology, etc. In this Volume 1, the application of various types of polymers in different wastewater treatment technologies are presented. The synthesis procedure of some polymers, the polymer modification, the effect of operational parameters on polymer efficiency, the interactions between polymers - dyes, etc are discussed. |
