The book is the first of its kind to deal with almost the entire
swath of water resources assessment, development and sustainable
management. The idea of the book crystallized during the long
journey of the Editors on various facets of water issues in India
and abroad during their extended association, at all levels with
the Ministry of Water Resources, River Development and Ganga
Rejuvenation, as well as International Organizations dealing with
water. Currently water-stressed, India is likely to become water
scarce in not too distant a future. The global freshwater supply
and its sustainable use for human consumption, and conservation of
the ecosystem have never come under such a rigorous scrutiny
before. The unplanned and reckless exploitation of this precious
resource have led to a crisis situation, compounded by a real
threat of climate change. This book is, therefore, timely and of
particular relevance not only to India but the entire world. The
book contains 20 chapters, beside the lead article by the Editors.
The chapters are contributed by the eminent professionals,
researchers, academicians and civil society representatives having
an in-depth understanding of the issues. The contents of the
chapters have been chosen to represent all aspects of water. The
assessment of water resources using satellite data and in-depth
analyses of groundwater sector like, the Aquifer Mapping Programme
initiated by Government of India, application of gravity satellite
data to assess the resource build up, artificial recharge of
aquifers and its contamination, are dealt with by eminent experts.
The articles on sustainable management of water through good
governance by community participation and involvement of civil
society are placed. Flood management both through a basin level
approach as well as by building resilience in vulnerable areas is
discussed. Other critical issues like water bodies management,
constitutional provisions, water governance and financial issues,
hydro-power and need of research and development in this sector are
also dealt with aptly. In view of emerging crisis and complexities
in this sector the future pathways and the paradigm shift that is
required in administrative and policy level is also discussed.
Part 5 of the 5-part Principles and Practices of Water Supply
Operations (WSO), this text provides a practical education in
mathematics, hydraulics, chemistry, and electricity. Hundreds of
problems and examples are included to relate these sciences
specifically to municipal water supply operations. This book is
referenced in the four other textbooks in the series. It is a
required text when used with other WSO series texts, but may be
used alone as a basic science text. Designed for self study or
classroom use, the Fourth Edition provides many new problems and
examples. Includes glossary, index, conversion tables, periodic
table of the elements, and color plates.
This book applies interactive perspectives, which have historically
mainly been discussed in the context of Western European countries,
to case studies on water governance in Asia. It examines how these
perspectives can be used to reveal complex and dynamic interactions
in water governance in Asia, and how interactions between policies
and practices, as well as those between formal institutes and
emerging informal institutes, come to pass. In two introductory
chapters and seven case studies in Asia (two from China, and each
one from Japan, Thailand, the Philippines, Indonesia, and India),
the book reveals the interactive forms currently emerging in Asia
under hierarchical but often fragmented administrative systems. In
addition, it explores emerging hybrid forms of interactive
governance, which bring together governmental and non-governmental
actors, and discusses how the expected role of government and roles
of non-governmental actors could be changed to solve problems in a
more cooperative manner. In this context, researchers from outside
the locality could play an important role, helping facilitate such
forms of interactive governance. The book offers extensive
information on the essential features of interactive forms, and on
the role of such transdisciplinary approaches, making it a valuable
resource not only for scholars and university students, but also
for policymakers and grass-roots practitioners directly involved in
the interactive process of water governance.

Arsenic contamination poses a major environmental problem,
especially in Southeast Asian countries like Bangladesh and India.
Threatening the health of millions of people due to arsenic's
toxicity and carcinogenicity, the major routes of arsenic exposure
for humans are either through drinking water or crops. Rice is the
crop most affected by arsenic owing to its cultivation in major
arsenic contaminated areas, biogeochemical factors in the soil
during rice growth, and specific features of rice that enable it
take up more arsenic than other crop plants. This book addresses
the problem of arsenic by pursuing a holistic approach. It presents
the status quo in different parts of the world (North and South
America, Europe, Asia, etc.) and provides essential information on
food-related arsenic exposure risks for humans, and possible
preventive and curative measures for tackling arsenic poisoning. It
covers the arsenic contamination status of rice, rice-based
products, other vegetables, fishes, mushrooms, and other foods,
with a special focus on rice-arsenic interactions. The mechanisms
of arsenic uptake, translocation and distribution in plants and
grains are also explained. In closing, the book reviews a variety
of prospective agronomic and biotechnological solutions to the
problem of arsenic accumulation in rice grains. The book is
intended for a broad audience including researchers, scientists,
and readers with diverse backgrounds including agriculture,
environmental science, food science, environmental management, and
human health. It can also be used as an important reference guide
for undergraduate and graduate students, university faculties, and
environmentalists.

Free Surface Flow: Environmental Fluid Mechanics introduces a wide
range of environmental fluid flows, such as water waves, land
runoff, channel flow, and effluent discharge. The book provides
systematic analysis tools and basic skills for study fluid
mechanics in natural and constructed environmental flows. As the
prediction of changes in free surfaces in rivers, lakes, estuaries
and in the ocean directly affects the design of structures that
control surface waters, and because planning for the allocation of
fresh-water resources in a sustainable manner is an essential goal,
this book provides the necessary background and research.
This book tries to answer the question how different communities in
such an arid area as the Iranian central plateau could have shared
their limited water resources in a perfect harmony and peace over
the course of history. They invented some indigenous technologies
as well as cooperative socio-economic systems in order to better
adapt themselves to their harsh environment where the scarce water
resources had to be rationed among the different communities as
sustainably as possible. Those stories hold some lessons for us on
how to adjust our needs to our geographical possibilities while
living side by side with other people. This work gives insight into
the indigenous adaptation strategies through the territorial water
cooperation, and describes how water can appear as a ground for
cooperation. It explains the water supply systems and social
aspects of water in central Iran. Topics include the territorial
water cooperation, qanat's, the traditional water management and
sustainability, the socio-economic context, the sustainable
management of shared aquifers system and more.

Renewable Energy Powered Desalination Handbook: Applications and
Thermodynamics offers a practical handbook on the use of renewable
technologies to produce freshwater using sustainable methods.
Sections cover the different renewable technologies currently used
in the field, including solar, wind, geothermal and nuclear
desalination. This coverage is followed by an equally important
clear and rigorous discussion of energy recovery and the
thermodynamics of desalination processes. While seawater
desalination can provide a climate-independent source of drinking
water, the process is energy-intensive and environmentally
damaging. This book provides readers with the latest methods,
processes, and technologies available for utilizing renewable
energy applications as a valuable technology. Desalination based on
the use of renewable energy sources can provide a sustainable way
to produce fresh water. It is expected to become economically
attractive as the costs of renewable technologies continue to
decline and the prices of fossil fuels continue to increase.
The establishment of clean, safe water is one of the major
challenges facing societies around the globe. The continued
urbanization of human populations, the increasing manipulation of
natural resources, and the resulting pollution are driving
remarkable burden on water resources. Increasing demands for food,
energy, and natural resources are expected to continue to
accelerate in the near future in response to the demands of these
changing human populations. In addition, the complexity of human
activities is leading to a diversity of new chemical contaminants
in the environment that represent a major concern for water
managers. This will create increased pressure on both water
quantity and quality, making it increasingly difficult to provide a
sustainable supply of water for human welfare and activities.
Although protection of water resources is the best long-term
solution, we will also need innovative novel approaches and
technologies to water treatment to ensure an adequate superior
quality resource to meet these needs. Solving tomorrow's water
issues will require unique approaches that incorporate emerging new
technologies. Great advances have been made in the area of
nanotechnology. Due to their unique physical and chemical
properties, nanomaterials are extensively used in antibacterial
medical products, membrane filters, electronics, catalysts, and
biosensors. Nanoparticles can have distinctly different properties
from their bulk counterparts, creating the opportunity for new
materials with a diversity of applications. Recent developments
related to water treatment include the potential use of carbon
nanotubes, nanocompositae, nanospheres, nanofibers, and nanowires
for the removal of a diversity of chemical pollutants. By
exploiting the assets and structure of these new materials, such as
increased surface area, high reactivity, and photocatalytic action,
it will be possible to create technologies that can be very
efficient at removing and degrading environmental pollutants.
Understanding and using these unique properties should lead to
innovative, cost-effective applications for addressing the
complexities of emerging needs for water treatment and protection.
Although still in the early stages, research into the application
of nanotechnology shows great promise for solving some of these
major global water issues. This comprehensive text describes the
latest research and application methods in this rapidly advancing
field.
This book provides a wide-range exploration on the ongoing research
and developmental events in environmental nanotechnology. Emerging
nanomaterials and its technology have been known to offer unique
advantages and are continually showing promising potential
attracting continuous global attention. This work thus discusses
experimental studies of various nanomaterials along with their
design and applications and with specific attention to chemical
reactions and their challenges for catalytic systems. It will make
a noteworthy appeal to scientists and researchers working in the
field of nanotechnology for environmental sciences.

This book focuses on interdisciplinary issues of human health in
the changing urban environments of India's largest megacities-Delhi
and Mumbai. The authors explore human health concerns related to
increased temperatures and air pollution in these cities in a study
based on primary data collected through interviews, as well as
secondary data on causes of mortality from 2001 to 2012. During
this period, the surface temperatures for both megacities were
mapped using Landsat Images. The rapidly increasing populations of
cities and urban centers alter ecosystem services such as water,
air and land cover, with disastrous impacts on health and
wellbeing, particularly in megacities. In 2015, polluted air was
estimated to have been responsible for 6.4 million deaths
worldwide, and it is projected that it will cause between 6 and 9
million deaths per year by 2060. In 2017, outdoor air pollution
resulted in 1.2 million deaths in India and brought about a 3% loss
in GDP. The increase in population, vehicles, and industries has
led to changes in land use and land cover and a rise in city
temperatures and air pollution, creating urban heat islands (UHIs).
Together, UHIs and air pollution have damaging impacts on human
health that range from stress and headache to asthma, bronchitis,
and chronic diseases, and even to death. Delhi has been
experiencing emergency conditions in terms of environmental health
over the past two years. At the same time, both the Delhi and
Mumbai urban agglomerations are growing at a rapid pace, and the
United Nations has projected that they will be the second and third
most populous cities in the world by 2025. In this context, the
book offers significant insights into the past patterns and
responses to the present global urban health emergencies, and
explores sustainable means of combating the problem to enable
college and university researchers to develop innovative solutions.
Further. It presents trans-disciplinary research that cuts across
the WHO Action Plan, the Sustainable Development Goals, the Sendai
Framework for Disaster Risk Reduction, and Habitat III to help
policymakers gain a better understanding of the global challenges
of urban health and wellbeing. The book is especially useful for
students and researchers in geography, urban demography, urban
studies, environmental studies, health sciences, and policy
studies.
This book aims to define the concept of Nature Based Solutions
(NBS) by using case studies from members of the European Innovation
Partnership (EIP) Water Action Group - NatureWat. NBS is defined
and characterized in terms of water source, contaminants, removal
mechanisms and resource recovery potential. The case studies
presented illustrate the appropriateness of NBS promoting climate
resilience. Readers will discover a technology portfolio based on a
number of demonstration sites in the fields of climate change
adaption, water and wastewater treatment, resource recovery and
re-use, and restoring ecosystems to promote the use of nature based
solutions. The chapters in the book present a multidisciplinary
approach involving social scientists, governance representatives
and engineers. The underlying philosophy of the book is the
circular economy of water which prioritizes the concepts of
resource recovery and resilience within water resource management.
The first section of the book presents the background and
objectives of the study, and how the action group aims to promote
the use of nature based solutions through its diverse technology
portfolio. Particular attention is given to the goals of finding
cost-effective solutions for wastewater treatment, climate change
mitigation, disaster risk reduction, flood protection, greening
cities, degraded areas restoration and biodiversity preservation.
The chapter on reclaimed water addresses water reuse and defines
the term fit for purpose. Barriers and limitations related to NBS
for water resource management are discussed. The book concludes
with several case studies at local, regional and global levels
which illustrate a new approach to water management. These case
studies illustrate the application of a hybrid green and grey
infrastructure system. This is a combination of traditional
engineered infrastructure with nature based solutions which
combines centralised and decentralised systems to optimise the
reclamation of water for reuse in a fit for purpose model.

This book presents a unique collection of up-to-date applications
of graphene for water science. Because water is an invaluable
resource and the intelligent use and maintenance of water supplies
is one of the most important and crucial challenges that stand
before mankind, new technologies are constantly being sought to
lower the cost and footprint of processes that make use of water
resources as potable water as well as water for agriculture and
industry, which are always in desperate demand. Much research is
focused on graphene for different water treatment uses. Graphene,
whose discovery won the 2010 Nobel Prize in physics, has been a
shining star in the material science in the past few years. Owing
to its interesting electrical, optical, mechanical and chemical
properties, graphene has found potential applications in a wide
range of areas, including water purification technology. A new type
of graphene-based filter could be the key to managing the global
water crisis. According to the World Economic Forum's Global Risks
Report, lack of access to safe, clean water is the biggest risk to
society over the coming decade. Yet some of these risks could be
mitigated by the development of this filter, which is so strong and
stable that it can be used for extended periods in the harshest
corrosive environments, and with less maintenance than other
filters on the market. The graphene-based filter could be used to
filter chemicals, viruses, or bacteria from a range of liquids. It
could be used to purify water, dairy products or wine, or in the
production of pharmaceuticals. This book provides practical
information to all those who are involved in this field.
