This book is written by the world's leading climatologists and
environmental scientists. It addresses many of the issues raised in
the debate on global change, providing a new point of view on
climate which is being integrated into the space and time
organization of societies. The volume contains three main parts: 1.
Climatic Changes and Fluctuations; 2. Climates on a Regional Scale,
including problems from tropical through temperate zones to polar
regions; and 3. Man-Climate Relationships on a Local Scale. Global
change is caused mainly by climatic variation and change and
activities of human societies. This book aims to describe these
facts from the various space scales - global, regional and local -
and also different time scales - post-glacial, historical and
recent periods. Since climate affects all kinds of human activities
such as agriculture, forestry, architecture, civil engineering,
transportation, tourism, health, etc., this book may contribute to
the work of researchers, planners and policy makers in a wide
variety of fields. For example, as indicated by the IPCC 1995
Report, adjustment of human societies is considered to be one of
the most important features in the 21st Century. For consideration
of these past, present and future problems, this book will provide,
in a systematic way, numerous sources of up-to-date knowledge.
This book provides an overview of the latest advances in
applications of nanocomposites in wastewater treatment. This book
is dedicated to recent developments in the application of polymer
nanocomposites to wastewater treatment. Based on their morphology
and tailored compositions, polymer nanocomposites provide powerful
tools for environmental remediation via selective adsorption of
contaminants in complex environmental matrices. The book reviews
recent progress in this field, covering various nanocomposite
fabrication routes and novel applications for pollutant sensing and
detection. It includes discussion of different types of
nanocomposites based on metal-organic frameworks and hydrogels,
while also covering related topics such as nanocomposite membranes,
photocatalysts, and bio-nanocomposites for pollution abatement.
Ideal for researchers and engineers in the field, this collection
of contributed chapters offers a timely review of current research
in nanomaterials for cost-effective pollution control technologies.
Since the HMS Challenger expedition of 1872-1876, our vision of the
ocean has changed completely. We now understand that it plays a key
role in biodiversity, climate regulation, and mineral and
biological resources, and as such, the ocean is a major service
provider for humanity. Oceans draws on data from new oceanographic
and satellite tools, acquired through international
interdisciplinary programs. It describes the processes that control
how the ocean functions, on different spatial and temporal scales.
After considering the evolution of concepts in physical, chemical
and biological oceanography, the book outlines the future of a
warmer, acidified, less oxygenated ocean. It shows how a view of
the ocean at different scales changes how we understand it.
Finally, the book presents the challenges facing the ocean in terms
of the exploitation of biological and mineral resources, in the
context of sustainable development and the regulation of climate
change.
Textile industry wastewater contains toxic dyes as well as heavy
metals and many other persistent organic compounds which are
difficult to biodegrade using conventional biological methods.
Advanced Oxidation Processes (AOPs) are one of the best
alternatives for the effective degradation of such compounds. This
Volume 2 starts with homogeneous and heterogeneous Fenton processes
and reviews the application and variables that affect the process.
It then discusses plasma technology- an emerging method in terms of
its chemistry, treatment set-up, limitations, etc. The positive
performance of carbon tetrachloride in process intensification of
dye degradation is presented. The other chapters include topics
such as sonoenzymatic treatment processes, electroflocculation
versus textile wastewater, combination of photocatalysis and
membrane Separation, and enhancement of anaerobic digestion and
photodegradation through adsorption.
This volume addresses the situation of water and wastewater
management from a global angle, underpinned by selected case
studies. Without doubt, water and wastewater management are among
the greatest challenges of our century, and there is also no doubt
that the challenges posed by climate change will become even
greater. However, most efforts, especially in developing countries
but also in the so-called developed countries, have been less than
optimal or not optimal at all. In particular, there are still too
many people who have to live without clean water and decent
sanitation. Today, 2.2 billion people lack access to safely managed
drinking water and wastewater, and 4.2 billion people lack safely
managed sanitation services. The question, why this is so and why
in many cases in developing countries, is discussed in this book
among other urgent water and wastewater management issues. The
publication of this book is the start of a book series that in more
detail critically reviews, discusses, and analyzes the water and
wastewater situation and management in different regions and
countries worldwide.
The world's oceans cover 70% of the earth's surface and are home to
a myriad of amazing and beautiful creatures. However, the
biodiversity of the oceans is incre- ingly coming under serious
threat from many human activities including overfi- ing, use of
destructive fishing methods, pollution and commercial aquaculture.
In addition, climate change is already having an impact on some
marine ecosystems. This book discusses some of the major threats
facing marine ecosystems by cons- ering a range of topics, under
chapters discussing biodiversity (Chapter 1), fisheries (Chapter
2), aquaculture (Chapter 3), pollution (Chapter 4) and the impacts
of increasing greenhouse gas emissions (Chapter 5). It goes on to
explore solutions to the problems by discussing equitable and
sustainable management of the oceans (Chapter 6) and protecting
marine ecosystems using marine reserves (Chapter 7). Presently, 76%
of the oceans are fully or over-exploited with respect to fishing,
and many species have been severely depleted. It is abundantly
clear that, in general, current fisheries management regimes are to
blame for much of the widespread degradation of the oceans. Many
policy-makers and scientists now agree that we must adopt a radical
new approach to managing the seas - one that is precautionary in
nature and has protection of the whole marine ecosystem as its
primary objective. This 'ecosystem-based approach' is vital if we
are to ensure the health of our oceans for future generations.
The carbon dioxide absorption and gas exchange at the sea surface,
marine aerosols and their photochemistry, the oceanic carbon cycle
as well as biomarkers in marine ecosystems, and related topics are
of primary importance for understanding our global ecosystem.
The topics addressed in this volume are all stemming from areas
which have developed only in the last ten years of research or
which have gone into decidedly new directions in that time. In most
cases, the recent research has been driven by advances in
instrumentation or by large-scale international cooperations. Thus
this volume is also aiming at interdisciplinary and international
cooperations in the future.
This book introduces the general principles of reaction equilibria
and kinetics involved in marine geochemical cycles. The major
electrolytes dramatically affect the rates and equilibria of the
chemical reactions in the sea. In order to understand these
interactions, it is necessary to have a detailed knowledge of the
major, minor and trace chemical components. This volume is also
focused on the development and applications of analytical
techniques for accurate determination and speciation in seawater,
and on the effect of pollution on the marine environment, since
small quantities of other elements may have a significant influence
on global chemical cycling. Audience: This book is of value for
marine chemists, biogeochemists, ecologists, oceanographers,
environmental engineers and analytical chemists.
One of the most crucial but still very poorly understood topics of
oceanographic science is the role of ocean processes in
contributing to the dynamics of climate and global change. This
book presents a series of high level lectures on the major
categories of ocean/atmosphere processes. Three of these major
issues are the focus of the lectures: (1) air--sea interaction
processes; (2) water mass formation, dispersion and mixing; (3)
general circulation, with specific emphasis on the thermohaline
component. Global examples in the world ocean are provided and
discussed in the lectures. In parallel, the Mediterranean Sea is a
laboratory basin in providing analogues of the above global
processes relevant to climate dynamics. They include the
Mediterranean thermohaline circulation with its own conveyor belt';
intermediate and deep water mass formation and transformations,
dispersion and mixing. No other book in the field provides a review
of fundamental lectures on these processes, coupled with global
examples and their Mediterranean analogues.
Multivariate Frequency Analysis of Hydro-Meteorological Variables:
A Copula-Based Approach provides comprehensive and detailed
descriptions of the approaches and techniques used in multivariate
frequency analysis (including, but not limited to copula
functions), with illustrative examples and real-life case studies
provided. The book presents all background material and new
developments in one place, presenting the material in a homogeneous
and pedagogical way in order to allow students, engineers and
researchers to access and efficiently use all information
surrounding this topic. This reference can be used as a guide to
apply the available and recent approaches to evaluate
hydro-meteorological risks, to design hydraulic structures, in
teaching (faculty members), and as a literature review to go to the
next steps in research projects (graduate students and postdocs).
Hydrodynamic and pollutant transport models are useful tools for
evaluating remediation options for polluted water bodies. These
models span the range from highly theoretical, fine resolution,
physically-based designs to lumped, black-box representations of
real world phenomena.
This book examines the numerical approaches used in hydrodynamic
and pollutant transport modeling. First, the theory and physical
basis of transport and mixing in lakes and coastal waters are
provided. Methodologies that use a three-dimensional (3D) approach
to predicting the fate and transport of pollutants are presented
and this is followed by a presentation of alternatives to 3D
circulation modeling as well as new advances in the field. These
alternatives offer near 3D accuracy but without the computational
burden. Illustrations of the calibration and verification of these
models using laboratory data, as well as, field data are also
provided. The models are applied to a diverse array of study sites
ranging from The Great Lakes in North America to the coastal areas
of Northern Crete.
*Presents the theory of hydrodynamic and pollutant transport
modelling in lakes and coastal areas
* Thoroughly examines the issues and limitations of the numerical
approaches used in hydrodynamic and pollutant transport
modelling
* Demonstrates the calibration and verification of hydrodynamic and
pollutant transport models using laboratory and field data
This book focuses, in seven chapters, on the perspectives and
solutions that different research groups offer to try to address
problems related to SDG 14: Life Below Water. The different
objectives developed in SDG 14 are treated independently, with an
attempt to give a global vision of the issues. The mechanism used
to select the book's content was through an Artificial Intelligence
program, choosing articles related to the topics by means of
keywords. The program selected those articles, and those that were
not related to the topic or did not focus on SDG 14 were discarded
by a subject matter expert. Obviously, the selection was partial
and the entire subject is not covered, but the final product gives
a very solid idea of how to orient ourselves to delve deeper into
the topic of SDG 14 using published chapters and articles. The AI
program itself selected the text of these contributions to show the
progress in different topics related to SDG 14. This mode of
operation will allow specialists (and non-specialists) to collect
useful information for their specific research purposes in a short
period of time. At a time when information is essential in order to
move quickly by providing concrete answers to complex problems,
this type of approach will become essential for researchers,
especially for a subject as vast as SDG 14.
The second edition of this book has been completely updated. It
studies the history and gives an analysis of extreme climate change
on Earth. In order to provide a long-term perspective, the first
chapter briefly reviews some of the wild gyrations that occurred in
the Earth's climate hundreds of millions of years ago: snowball
Earth and hothouse Earth. Coming closer to modern times, the
effects of continental drift, particularly the closing of the
Isthmus of Panama are believed to have contributed to the advent of
ice ages in the past three million years. This first chapter sets
the stage for a discussion of ices ages in the geological recent
past (i.e. within the last three million years, with an emphasis on
the last few hundred thousand years).
Research on historical earthquakes and tsunamis in the Iberian
Peninsula has made great strides in recent years, from diverse
scientific fields ranging from geology to archaeology. In addition
to the famous earthquake and tsunami of 1755, which intensely
affected the peninsula, researchers are conducting a growing number
of surveys and case studies on seismic episodes and extreme wave
events of possible tsunamigenic origin in Portugal and Spain during
the ancient, medieval, and modern eras. However, the development of
these studies has suffered due to a certain lack of communication
among the different fields of research, which are focused on their
own methodologies and interests. The aim of this book is to promote
interdisciplinary dialogue by linking the results of the most
recent research into historical earthquakes and tsunamis in Iberia
from the fields of geology, history and archaeology. The volume,
which devotes special attention to tsunamis and to events that
occurred in the Iberian Peninsula before 1755, offers synthetic
insights, updates, and case studies of maximum interest for
knowledge of the historical seismology of Portugal and Spain.
The Asian monsoon and associated river systems supply the water
that sustains a large portion of humanity, and has enabled Asia to
become home to some of the oldest and most productive farming
systems on Earth. This book uses climate data and environmental
models to provide a detailed review of variations in the Asian
monsoon since the mid-Holocene, and its impacts on farming systems
and human settlement. Future changes to the monsoon due to
anthropogenically-driven global warming are also discussed. Faced
with greater rainfall and more cyclones in South Asia, as well as
drying in North China and regional rising sea levels, understanding
how humans have developed resilient strategies in the past to
climate variations is critical. Containing important implications
for the large populations and booming economies in the Indo-Pacific
region, this book is an important resource for researchers and
graduate students studying the climate, environmental history,
agronomy and archaeology of Asia.
This book presents an analysis of land and water resources in
Siberia, initially characterizing the landscapes, their ecosystems,
crucial processes, human impacts on soil and water quality, and the
status quo of available research. Further chapters deal with modern
monitoring and management methods that can lead to a significant
knowledge shift and initiate sustainable soil and water resources
use. These include soil hydrological laboratory measurement
methods; process-based field evaluation methods for land and water
quality; remote sensing and GIS technology-based landscape
monitoring methods; process and ecosystem modeling approaches;
methods of resource and process evaluation and functional soil
mapping; and tools for controlling agricultural land use systems.
More than 15 of these concrete monitoring and management tools can
immediately be incorporated into research and practice. Maintaining
the functions of great landscapes for future generations will be
the reward for these efforts.
The textile industry is among the most significant polluters of
water owing to the existence of various types of pollution streams
generated by printing processes and textile dyeing. The book begins
by documenting various types of Poly (vinyl alcohol) PVA-derived
adsorbents (gels, fibers, films, composite particles), membranes,
and photocatalysts in combination with conventional adsorbents,
polymers, carbonaceous and metallic materials and their use in
elimination of dyes from contaminated water. It follows by
discussing different properties of nanocomposite membranes such as
hydrogels, xerogels and aerogels used in this purpose. Also,
different polymer - based adsorbents such as ceramic adsorbent,
clay, hydrogels, starch, cellulose, chitosan, alginates, etc are
presented in this book.
This book focuses on understanding the shoreline dynamics,
nearshore processes and sediment transport around Rameswaram Island
and the cities of Dhanushkodi and Arichamunai. Rameswaram Island is
located between the Gulf of Mannar on the south and Palk Bay on the
north, between the southern tip of India and Sri Lanka, and is
unique in terms of physical, chemical and biological processes. The
Gulf of Mannar is established as a marine biodiversity conservation
area by its richness of variety and variability of marine species
such as corals, finfish, shellfish and other fishes. The island is
predominantly influenced by four seasons: northeast monsoon,
post-monsoon, summer and southwest monsoon; and the
sedimentological and hydrodynamic conditions significantly change
seasonally, resulting in the island's responding in a different
manner with each season. It also explains the physical forces and
their impacts around these areas. Rameswaram Island has existed
naturally for a long period of time even under the influence of
different water masses of the Gulf of Mannar and Palk Bay.
Understanding the regional natural phenomena is the only solution
to carry out the best management practices to develop coastal
constructions and modifications.
Caribbean Tsunamis - A 500-Year History from 1498-1998 broadly
characterizes the nature of tsunamis in the Caribbean Sea, while
bearing in mind both scientific aspects as well as potential
interest by the many governments and populations likely to be
affected by the hazard. Comprehension of the nature of tsunamis and
past effects is crucial for the awareness and education of
populations at risk.
Audience: This book provides a thorough, yet highly accessible
review of tsunamis in the Caribbean. It is of interest not only to
tsunami and natural hazards specialists at academia and
governmental institutes, but also to policy makers and to the
general public.
This authoritative guide enables accurate identification of the
common components of the inshore benthic invertebrates of the
British Isles and adjacent European coasts, as well as a
substantial proportion of fish species. This new edition builds
upon the strengths of the earlier work and is thoroughly revised
throughout to incorporate advances in both the taxonomy and ecology
of the organisms concerned.
This book demonstrates various types of deepwater risers with
different motion equations and boundary conditions depending on
their different structural configurations. It also discusses the
hydrodynamic analysis methods of different deepwater risers. It
provides new force and structure models in time and frequency
domains of vortex induced force, including that for a downstream
riser of the tandem riser, and the rigid oscillating model for
steel catenary riser. The highlights of this book are the analysis
methods of the rigid oscillating mode of steel catenary riser and
the coupling iteration for top-tensioned riser with pipe-in-pipe
configuration. This book is interesting and useful to a wide
readership in the various fields of ocean engineering and offshore
oil & gas development.
This book provides the world community with the most up-to-date and
comprehensive scientific and technical knowledge based on climate
change impact assessment, adaptation and mitigation strategies in
the Indian Himalayan region. It identifies major issues related to
climate change on environmental sustainability, focusing on impact
measurement, policy, adaptation and mitigation strategies at
national, regional and local scales. There is a need to strengthen
the global response in order to cope with the threat of climate
change. The main objective of this book is to update the
understanding of scientific analysis and to promote evidence-based
policy formulation at regional and local levels. This book on
climate change is used as a reference material to climate change
for new learners interested in the mountainous region of the Indian
Himalayas. This comprehensive book covers a wide range of potential
research areas including climate change scenarios, science and its
applications, adaptation to climate change theory and assessment,
water resources, agriculture, human health, forest, biodiversity,
ecosystems, indigenous knowledge, etc.
The Upper Adriatic Sea basin comprises a very precarious coastal
environment subject to continuous changes which prove appreciable
not only over the geological scale but also in historical and
modern times. According to some Authors the Venice Lagoon was
formed 2000-3000 years ago, and other lagoons (e. g. the Grado
Lagoon in the northernmost part of the Adriatic) are even more
recent. In addition to lagoons, the Upper Adriatic coastal area
includes salt and fresh-water marshes and reclaimed land separated
by several watercourses originating from the Alpine and Apennine
ranges with a ground elevation not exceeding in many places 2 m
above the mean sea l. evel (msl). A significant fraction of this
lowland is already now below msl because of natural and
anthropogenic land subsidence, land reclamation and sea level rise
occurred over the last century. Natural land subsidence is still
under way as a result of deep downward tec tonic movement and
consolidation of soils deposited in the most recent time. An
thropogenic subsidence is primarily due to groundwater pumping for
agricultural, industrial, civil, and tourist use, and to gas
withdrawal from a large number of gas fields scattered through the
Upper Adriatic basin, and may still continue, al though at a
reduced rate, in the years to come. At the same time msl is
expected to rise in the next century due to global climate change,
mainly because of the greenhouse effect.
