This volume offers an overview of the occurrence of emerging
organic contaminants in Mediterranean rivers and their relevance to
their chemical and ecological quality under water scarcity. With
chapters covering the effects under multiple stress conditions of
pharmaceuticals, polar pesticides, personal care products, and
industrial chemicals, the observations presented can be applicable
to other parts of the world where water scarcity is an issue . It
is of interest to environmental chemists, ecologists, environmental
engineers, and ecotoxicologists, as well as water managers and
decision-makers.
The management of a water supply network can be substantially
improved defining permanent sectors or districts that enhances
simpler water loss detection and pressure management. However, the
water network partitioning may compromise water system performance,
since some pipes are usually closed to delimit districts in order
not to have too many metering stations, to decrease costs and
simplify water balance. This may reduce the reliability of the
whole system and not guarantee the delivery of water at the
different network nodes. In practical applications, the design of
districts or sectors is generally based on empirical approaches or
on limited field experiences. The book proposes a design support
methodology, based on graph theory principles and tested on real
case study. The described methodology can help water utilities,
professionals and researchers to define the optimal districts or
sectors of a water supply network.
This volume provides a comprehensive perspective on geomorphic
approaches to management of lowland alluvial rivers in North
America and Europe. Many lowland rivers have been heavily managed
for flood control and navigation for decades or centuries,
resulting in engineered channels and embanked floodplains with
substantially altered sediment loads and geomorphic processes. Over
the past decade, floodplain management of many lowland rivers has
taken on new importance because of concerns about the potential for
global environmental change to alter floodplain processes,
necessitating revised management strategies that minimize flood
risk while enhancing environmental attributes of floodplains
influenced by local embankments and upstream dams. Recognition of
the failure of old perspectives on river management and the need to
enhance environmental sustainability has stimulated a new approach
to river management. The manner that river restoration and
integrated management are implemented, however, requires a case
study approach that takes into account the impact of historic human
impacts to the system, especially engineering. The river basins
examined in this volume provide a representative coverage of the
drainage of North America and Europe, taking into account a range
of climatic and physiographic provinces. They include the 1)
Sacramento (California, USA), 2) San Joaquin (California), 3)
Missouri (Missouri, USA), 4) Red (Manitoba, Canada and Minnesota,
USA), 5) Mississippi (Louisiana, USA), 6) Kissimmee (Florida, USA),
7) Ebro (Spain), 8) Rhone (France), 9) Rhine (Netherlands), 10)
Danube (Romania), and 11) Volga (Russian Federation) Rivers. The
case studies covered in these chapters span a range of fluvial
modes of adjustment, including sediment, channel, hydrologic
regime, floodplains, as well as ecosystem and environmental
associations.
The use of water for industrial purposes is of foremost importance.
It is used as a coolant and industrial activities dealing with
power generation, steel and iron, paper and pulp and oil require
very large amounts of water. The industry, therefore, resorts to
large scale abstraction of water from natural water bodies. This
water is often treated with chemicals to combat operational
problems like biofouling and corrosion. Such withdrawal and
subsequent discharge of large amounts of water have the potential
to impart significant impact on the recipient water body. The
organisms drawn along with the cooling water, as well as those
residing at the discharge zone, are subjected to a combination of
mechanical, thermal and chemical stress on a continuous basis.
The 2nd International Conference on Sustainable Innovation
emphasizes on natural resources technology and management to
support the sustainability of mankind. The main theme of ICoSI 2014
"Technology and innovation challenges in natural resources and
built environment management for humanity and sustainability "
reflects the needs of immediate action from scientists with
different fields and different geographical background to face the
global issue on world's change.
The book presents the state-of-the-art document describing the
knowledge, data, cost-effectiveness and technologies employed to
manage the waste in several countries such as Morocco, Tunisia,
Egypt, Jordon, Syria, Palestine, Lebanon, and Yemen. It covers
diverse topics including the status of the waste in the region,
solid waste management, solid waste recovery and disposal, the use
of the agricultural waste in feeding poultry, sludge disposal and
management, wastewater treatment and energy production. Also, the
book explains how waste management systems are becoming more
complex in many countries with the move from landfill-based to
resource recovery-based solutions following the setting of
international and national targets to divert waste from landfill
and to increase recycling and recovery rates. Besides, this book
also evaluates the environmental legislation in the selected
countries and suggests new performance enhancements. This book is
of interest to environmental professionals including scientists and
policymakers in the Middle East, North Africa, and areas with
similar features.
The book examines how the absence of insurance in the past led to
some special maritime liability law principles such as 'general
average' (i.e., losses or expenses shared by all the parties to a
maritime adventure) and the limitation of shipowners' liability. In
the absence of insurance, these principles served the function of
insurance mostly for shipowners. As commercial marine insurance is
now widely available, these principles have lost their
justification and may in fact interfere with the most important
goal of liability law i.e., deterrence from negligence. The work
thus recommends their abolition. It further argues that when
insurance is easily available and affordable to the both parties to
a liability claim, the main goal of liability law should be
deterrence as opposed to compensation. This is exactly the case
with the maritime cargo liability claims where both cargo owners
and shipowners are invariably insured. As a result, the sole focus
of cargo liability law should be and to a great extent, is
deterrence. On the other hand in the vessel-source oil pollution
liability setting, pollution victims are not usually insured.
Therefore oil pollution liability law has to cater both for
compensation and deterrence, the two traditional goals of liability
law. The final question the work addresses is whether the deterrent
effect of liability law is affected by the availability of
liability insurance. Contrary to the popular belief the work
attempts to prove that the presence of liability insurance is not
necessarily a hindrance but can be a complementary force towards
the realization of deterrent goal of liability law.
The coastal and ocean ecosystem is a significant feature of our
planet and provides a source of food for much of life on Earth.
Millions of species have been, and are still being discovered in
the world's oceans. Among these zooplankton serve as secondary
producers and are significant as they form pelagic food links and
act as indicators of water masses. They constitute the largest and
most reliable source of protein for most of the ocean's fishes. As
such, their absence or depletion often affects fishery. In many
countries, the decline in fishery has been attributed to reduced
plankton populations. Furthermore, trillions of tiny copepods
produce countless faecal pellets contributing greatly to the marine
snow and therefore accelerating the flow of nutrients and minerals
from the surface waters to the seabed. They are phylogenetically
highly successful groups in terms of phylogenetic age, number of
living species and success of adaptive radiation. A study of the
basic and applied aspects of zooplankton would provide an index of
the fishery potential and applications, offering insights into
ocean ecology to safeguard food supplies and livelihoods of the
millions of people living in coastal areas. For this reason, we
need to understand all the facets of zooplankton as well as their
interactions with atmosphere and other life forms, including human.
In this context, this book discusses the basic and applied aspects
of zooplankton, especially taxonomy, mosquitocidal activity,
culture, analysis of nutritional, pigments and enzyme profile,
preservation of copepods eggs, bioenrichment of zooplankton and
application of zooplankton in sustainable aquaculture production,
focusing on novel biofloc-copefloc technologies, and the impact of
acidification and microplastics on zooplankton. Offering a
comprehensive overview of the current issues and developments in
the field of environmental and commercial applications, this book
is a valuable resource for researchers, aquaculturists,
environmental mangers wanting to understand the importance of
zooplankton and develop technologies for the sustainable production
of fish and other commodities to provide food and livelihoods for
mankind.
The production of wastewater from various human and industrial
activities has a harsh impact on the environment. Without adequate
treatment, the disposal of this wastewater poses a threat to the
quality of water globally. Technologies for the Treatment and
Recovery of Nutrients from Industrial Wastewater investigates
emergent research and best practices within the field of wastewater
management. Highlighting novel technological tools in wastewater
treatment, effective nutrient removal technologies, and innovative
solutions to quality water preservation practices, this book is a
critical reference source for professionals, scientists, academics,
and students.
The world is facing a drinking water crisis. Besides continuous
population growth, uneven distribution of water resources and
periodic droughts have forced scientists to search for new and
effective water treatment, remediation and recycling technologies.
Therefore, there is a great need for the development of suitable,
inexpensive and rapid wastewater treatment and reuse or
conservation methods. This title discusses different types of
wastewater treatment, remediation and recycling techniques, like
adsorption, membrane filtration and reverse osmosis. It
alsoprovides guidance for the selection of the appropriate
technologies or their combinations for specific applications so

This book is a compilation of papers examining the impacts of
global change (GC) on water resources systems. Mainly focusing on
groundwater resources in Western Mediterranean countries, it shows
that this topic is one of the most important challenges facing
society. The papers explore developments in both Southern Europe
and North Africa, where major impacts on the sustainability,
quantity, quality, and management of water resources are expected
to emerge. Although most global change publications focus on
surface water, the number of research papers addressing global
change and groundwater has grown rapidly in recent years.
Continuing that welcome trend, this book gathers the main findings
presented at the "Congress on Groundwater and Global Change in the
Western Mediterranean" (Granada, Spain, November 6-9, 2017), which
brought together researchers and technicians interested in
groundwater issues affecting this geographic area.

Papers presented at the 11th International Conference on
Sustainable Water Resources Management are included in this volume.
These research works highlight recent technological and scientific
developments associated with the management of surface and
sub-surface water resources and as well as river basin management
methodologies. Water is essential for sustaining life on our planet
and its uneven distribution is a source of permanent conflict. The
growth of human population combined with the irregularity in
precipitation and water availability may restrict even further the
access to water in certain regions of the world. This problem is
made more severe by anthropogenic activities that affect its
quality. River Basin Management includes all aspects of Hydrology,
Ecology, Environmental Management, Flood Plains and Wetlands.
Riverine systems are coming under increasing pressure due to
anthropological and natural causes. Prominent amongst the problems
affecting them is water scarcity and quality, which requires the
development of improved methods for better river management. This
volume features research from professionals involved in sustainable
water resources management and provides an insight into the state
of the art in the current technology, techniques and solutions in
that field as they have been developed and applied in different
countries.
This book provides a systematic exposition of the design features
of constructed wetlands, and their management (in terms of siting,
physical maintenance, and operation). Only very few books (or
chapters) have been published on constructed wetlands in tropical
conditions and none are current. The selection of plant species,
managing their growth and harvesting cycles, and the impact these
have on the attenuation of organic and inorganic pollutants,
nutrients, and pathogens would be of interest to students and
practitioners of the art working under tropical conditions. The
potential of constructed wetlands as a low-cost intervention for
developing countries in tropical regions that faced water pollution
problems, in particular, deserves to be explored systematically.

plasma reactors and diagnostics, and state-of-the-art environmental
applications of plasma. As such, it represents a valuable reference
guide for scientists, engineers and graduate students in the fields
of environmental science and plasma physics.
The past 30 years have seen the emergence of a growing desire
worldwide that positive actions be taken to restore and protect the
environment from the degrading effects of all forms of pollution -
air, water, soil, and noise. Since pollution is a direct or
indirect consequence of waste, the seemingly idealistic demand for
"zero discharge" can be construed as an unreal- tic demand for zero
waste. However, as long as waste continues to exist, we can only
attempt to abate the subsequent pollution by converting it to a
less noxious form. Three major questions usually arise when a
particular type of pollution has been identi?ed: (1) How serious is
the pollution? (2) Is the technology to abate it available? and (3)
Do the costs of abatement justify the degree of abatement achieved?
This book is one of the volumes of the Handbook of Environmental
Engineering series. The principal intention of this series is to
help readers formulate answers to the last two questions above. The
traditional approach of applying tried-and-true solutions to
speci?c pollution p- blems has been a major contributing factor to
the success of environmental engineering and has accounted in large
measure for the establishment of a "methodology of pollution
control. " However, the realization of the ever-increasing
complexity and interrelated nature of current environmental
problems renders it imperative that intelligent planning of
pollution abatement systems be undertaken.
This book discusses how climate change and heat islands are a main
contributor to water related problems in urban areas in Kosice,
Slovakia. Green roofs are used as a tool to assist in solving these
water related issues. The need to provide housing in urban areas is
expected to rise to 66% in 2050, according to the United Nations.
Many urban areas have seen natural permeable green areas replaced
with concrete constructions and hard, non-permeable surfaces. The
densification of existing built-up areas is responsible for the
decreasing vegetation, which results in the lack of
evapotranspiration cooling the air, thereby creating urban heat
islands. Several studies, discussed in this book, have shown that
natural and permeable surfaces, as in the case of green roofs, can
play a crucial role in mitigating this negative climate phenomenon
and providing higher efficiency for buildings, leading to savings
such as water, one of the focal points of this research.
