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.
The new edition of a bestseller, Water Flow in Soils bridges the fields of soil physics-where descriptions of water flow tend to be microscopic- and hydrology - where they tend to be macroscopic. Unlike other physics laden texts, this work conveys the fundamental concepts of water flow in soils with clear and essentially nonmathematical explanations. Using abundant illustrations, figures, and equations, the author introduces soil water flow, taking both a phenomenological and analytical approach. He elegantly elucidates the basic and advanced principles of water movement in soils.
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.
Sustainable management of water resources is quickly increasing in importance on a global scale. An important piece of the puzzle is the characterization of marine water and determining its importance to geochemical budgets. To do this, submarine groundwater discharges must be carefully studied. Comprehensively exploring the subject, Submarine Groundwater presents quantitative data relating groundwater contribution to the water/salt balance of regional and global bodies of water. The authors examine different data-supported methods for studying submarine groundwater flow and discharge through case studies contributed by leading international scientists. They discuss the maintenance of optimal water, salt, temperature and hydrobiological regimes of inland seas and large lakes. The book covers subsurface water exchange between the land and sea as well as groundwater discharge to the seas. It also provides a review of experimental methods and numerical modeling that can be used for the evaluation of specific discharge data and the effect of groundwater on the salt balance of seas and oceans. Defining the field of marine hydrogeology as a science that studies submarine groundwater, its properties, circulation, and distribution, Submarine Groundwater delineates the role of quantitative assessment of subsurface water exchange between land and sea in predicting its changes under the influence of natural factors and human activity. It provides a framework for assessing different methods and making the best choice for various situations.

"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."
Beneath the coastal waters of the world lie thousands of artificial reefs. Some are old and retired freighters and ships that once plied the oceans of the world but now serve as habitats for marine life. Others are newer reefs that have been designed and built for specific applications. With the field of aquatic habitat technology continually growing, this book responds to the global need for a compendium of consistent and reliable practices with which to evaluate how well artificial reefs meet their objectives. Artificial Reef Evaluation With Application to Natural Marine Habitats is a comprehensive guide to the methods used to document the performance of artificial reefs in coastal and oceanic waters. It is the first volume to combine the essential disciplines required for proper evaluation, including engineering, economics, biology, and statistics. This work covers the design of reef studies, multi-disciplinary methods of investigation, data analysis, and examples of applying the methods to reefs built for different purposes. Further, the methods examined in this book apply to other benthic marine habitats, such as coral reefs or "live bottoms", thus expanding the book's relevance to a wider audience and enhancing research efforts in the field of artificial habitat technology.

Climate hazards are the world's most widespread, deadliest and costliest natural disasters. Knowledge of climate hazard dynamics is critical since the impacts of climate change, population growth, development projects and migration affect both the impact and severity of disasters. Current global events highlight how hazards can lead to significant financial losses, increased mortality rates and political instability. This book examines climate hazard crises in contemporary Asia, identifying how hazards from the Middle East through South and Central Asia and China have the power to reshape our globalised world. In an era of changing climates, knowledge of hazard dynamics is essential to mitigating disasters and strengthening livelihoods and societies across Asia. By integrating human exposure to climate factors and disaster episodes, the book explores the environmental forces that drive disasters and their social implications. Focusing on a range of Asian countries, landscapes and themes, the chapters address several scales (province, national, regional), different hazards (drought, flood, temperature, storms, dust), environments (desert, temperate, mountain, coastal) and issues (vulnerability, development, management, politics) to present a diverse, comprehensive evaluation of climate hazards in Asia. This book offers an understanding of the challenges climate hazards present, their critical nature and the effort needed to mitigate climate hazards in 21st-century Asia. Climate Hazard Crises in Asian Societies and Environments is vital reading for those interested and engaged in Asia's development and well-being today and will be of interest to those working in Geography, Development Studies, Environmental Sciences, Sociology and Political Science.

Summarizing the state of the science and developments in engineering, the book describes: Common sources of perchlorate Its behavior in the environment Methods for analyzing perchlorate in environmental samples Potential risks to human health and the environment Regulatory standards and criteria Techniques for remediating environmental contamination The authors illustrate these points with case studies of perchlorate contamination in soil, groundwater, and surface water. These case studies provide perspective on issues commonly faced by scientists, engineers, and managers of perchlorate-impacted sites. Organized to follow the logical sequence of identifying and solving contamination problems, the book provides the foundation necessary to understand perchlorate's occurrence, environmental behavior, regulatory status, and remediation.
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.

Watershed Health Monitoring: Emerging Technologies is a concise reference that defines the concept of watershed health and explains that monitoring the health of watersheds is a critical precursor to adaptive resource management on a watershed basis. The focus of the text is a clear description of an innovative "Closed Loop" model that specifies four key aspects of successful monitoring programs: political linkages and support, sound scientific assessment techniques, a community education and awareness component; and a sustainable cost-recovery framework achieved through partnership. Divided into two sections, the book begins with an introduction that defines watershed health, explains how monitoring fits into watershed planning and management, describes frequent shortfalls of monitoring programs around the world (with an emphasis on North America) and proposes a "Closed Loop" approach that will help ensure successful programs. Subsequent chapters detail each component of the "Closed Loop" model with special emphasis on scientific assessment. The second part features a set of six case studies that describe successful real-world applications of the "Closed Loop" approach to watershed monitoring. Written in an easily understood manner with the practitioner in mind, Watershed Health Monitoring balances the need for a detailed yet concise treatment of the topic of watershed health monitoring. It is the first book to recognize the multidisciplinary nature of successful monitoring programs-programs that go far beyond science.

Bringing together a multidisciplinary set of scholars and diverse case studies from across the globe, this book explores the management, governance, and understandings around water, a key element in the assemblage of hydrosocial territories. Hydrosocial territories are spatial configurations of people, institutions, water flows, hydraulic technology and the biophysical environment that revolve around the control of water. Territorial politics finds expression in encounters of diverse actors with divergent spatial and political-geographical interests; as a result, water (in)justice and (in)equity are embedded in these socio-ecological contexts. The territory-building projections and strategies compete, superimpose and align to strengthen specific water-control claims of various interests. As a result, actors continuously recompose the territory's hydraulic grid, cultural reference frames, and political-economic relationships. Using a political ecology focus, the different contributions to this book explore territorial struggles, demonstrating that these contestations are not merely skirmishes over natural resources, but battles over meaning, norms, knowledge, identity, authority and discourses. The articles in this book were originally published in the journal Water International.
