Now and in the future, the ever-growing demand for drinking water will lead many cities to implement indirect water reuse programs, where wastewater effluent becomes part of the drinking water sources. Pollution of those sources with emerging contaminants (micropollutants) such as endocrine disrupting compounds, pharmaceutically active compounds, pesticides and personal care products is a fact known worldwide. In this thesis, nanofiltration (NF) and reverse osmosis (RO) are demonstrated to be appropriate technologies for removing a large number of micropollutants; however, the performance of NF and RO can be questioned because there are limited tools that optimise quantification of the removal of contaminants. Therefore, in this thesis, by means of the use of multivariate data analysis techniques, removal quantification is effectively determined and more understanding of the separation of micropollutants by membranes is achieved.
This study presents an systematic approach to water quality assessment, hybrid modelling and decision support for eutrophication management in deep reservoirs. It is found that during the summer monsoon the catchment runoff into the Yongdam reservoir induces a trandsfer of pollutants from a middle stratified layer to the surface layer. Although the transport mechanism limits nutrient accumulation on the bottom of the reservoir, it also offers an opportunity for on-going algae production in the surface water. Physically based modelling is used to understand the process of micro-scale turbulent mixing and its impact on the nutrient uptake by algae. Further, a data-driven model using clustering and partial least squares regression which uses results from a physically based model of the reservoir successfully predicts Chlorophyll-a concentrations.
This thesis presents the implementation of fully three-dimensional sediment transport and morphological updating formulations within a proven three-dimensional hydrodynamic flow solver. The thesis briefly discusses the formulations used to model both suspended and bed-load transport of non-cohesive sediment, and describes the implementation of a morphological updating scheme which incorporates novel approaches to morphological acceleration and dry bank erosion. Approaches used to model the three-dimensional effects of waves on coastal hydrodynamics and of three-dimensional currents on waves are also discussed. Results of several validation studies are presented and the model is shown to perform well in a series of simplified theoretical, laboratory, and full scale test cases. Application of the model and acceleration techniques to the complex and dynamic entrance to Willapa Bay, WA, USA is also discussed. Model processes are validated against the results of an extensive field measurement campaign, and diagnostic morphological model simulations are performed for two historical periods of contrasting morphological development. Input reduction and morphological acceleration techniques used to perform 5-year simulations of Willapa Bay are critically analysed and a new generic method to select a representative morphological tide for coastal environments containing significant diurnal tidal energy is presented.
Merchant Ship Types provides a broad and detailed introduction to the classifications and main categories of merchant vessels for students and cadets. It introduces the concept of ship classification by usage, cargo type, and size, and shows how the various size categories affect which ports and channels the types of vessels are permitted to enter. Detailed outlines of each major vessel category are provided, including: Feeder ship General cargo vessels Container ships Tankers Dry bulk carriers Multi-purpose vessels Reefer ships Roll-on/roll-off vessels The book also explains where these are permitted to operate, the type of cargoes carried, and specific safety or risk factors associated with the vessel class, as well as their main characteristics. Relevant case studies are presented. The textbook is ideal for merchant navy cadets at HNC, HND, and foundation degree level in both the deck and engineering branches, and serves as a general reference for insurance, law, logistics, offshore and fisheries.
Computer vision-based crack-like object detection has many useful applications, such as pavement surface inspection, underground pipeline inspection, bridge cracking monitoring, railway track assessment, etc. However, in most contexts, cracks appear as thin, irregular long-narrow objects, and often are buried into complex, textured background with high diversity which make the crack detection very challenging. During the past a few years, the deep learning technique has achieved great success and has been utilized for solving a variety of object detection problems. However, using deep learning for accurate crack localization is non-trivial. This book discusses crack-like object detection problem in a comprehensive way. It starts by discussing traditional image processing approaches for solving this problem, and then introduces deep learning-based methods. The book provides a comprehensive review of object detection problems and focuses on the most challenging problem, crack-like object detection, to dig deep into the deep learning method. It includes examples of real-world problems, which are easy to understand and could be a good tutorial for introducing computer vision and machine learning.
Methane Emissions from Unique Wetlands in China: Case Studies, Meta Analyses and Modelling is a landmark volume in the development of studies about methane emission from wetlands. Although there are books about methane emissions from rice paddies, natural wetlands and reservoirs, this book is the first one that provides information about methane emission from wetlands in China. Moreover, the book picks up very unique wetlands, alpine wetlands on the eastern edge of the Qinghai-Tibetan Plateau, and Three Gorges Reservoir (the world's largest hydroelectric reservoir) as cases to study methane emissions. It reviews and meta-analyses methane emissions from rice paddies, natural wetlands and lakes in China during the past twenty years. Furthermore, this book acts as bridge to connect microbial ecology and modelling: it both describes methane-producing bacteria dynamics and methane emission modelling.
1 2 Prof. Dr. Vladimir Mikhailovitsh Kolodkin, Prof. Dr.-Ing. Wolfgang Ruck 1 Institute of Natural and Technogenic Disasters, Udmurt State University, Izhevsk (Russia), 2 Institute of Ecology and Environmental Chemistry, University Luneburg (Germany) During the Cold War a whole arsenal of deadly chemical weapons was allowed to build up on both sides of the ideological divide. Happily, today the problems are reversed. Expertise is now required in the field of safe and environment-friendly disposal of chemical weapons and cleaning up of contaminated sites all around the world, but not least in the ex-Soviet-led countries. The participants and speakers to the NATO-Russia advanced research workshop on the "Ecological Risks Associated with the Destruction of nd th Chemical Weapons," hosted by the University of Luneburg on 22 - 26 October, 2003, therefore, came from many different parts of the world. Of the eight countries represented at the workshop, two were ex-Eastern- Block, and six were Western countries. Yet the West was by no means overrepresented. On the contrary, the Russian expert-speaker contingent, with 33 participants, did justice to the size of their country - and to their chemical-weapons problem - and provided the majority of active participants. In all, there were 57 participants, of which 11 dispatched from the TACIS project "The development of the chemical weapons" facility at the detached plant No 4 of OAO Khimprom, Novocheboksarsk."
In this unique book, Alain Guilloux uses four major elements of governance - namely norms, actors, processes, and outcomes - to examine Taiwan 's national governance as well as its participation in global governance in relation to humanitarian aid. Including case studies on Taiwan 's application to become an observer to the WHO, and its foreign-aid policy and practice dealing with disease outbreaks and natural disasters, Guilloux explores the complexities and dilemmas of providing humanitarian aid to people in need and distress. Taking into account Taiwan's unclear status in the global arena, and how in its efforts Taiwan faces both international isolation and opposition from the People's Republic of China at multiple levels. Taiwan, Humanitarianism and Global Governance will be of interest for scholars of Chinese studies, Taiwan Studies, East Asian politics and International Relations, and environmental politics and humanitarian studies.
In this work, several modelling approaches are explored to represent spatial pattern dynamics of aquatic populations in aquatic ecosystems by the combination of models, knowledge and data in different scales. It is shown that including spatially distributed inputs
retrieved from Remote Sensing images, a conventional
physically-based Harmful Algal Bloom model can be enhanced. Also,
Cellular Automata based models using high resolution photographs
prove to be good in representing aquatic plant growth. Multi-Agent
Systems can capture well the spatial patterns exhibited in GIS
density maps. A synthesis modelling framework was developed to
include biological/ecological growth and diffusive processes, and
local effects in conventional modelling framework. The results of
the complementary modelling paradigms investigated in this research
can be of help in achieving a sustainable environmental management
strategy.

International concern in scientific, industrial, and governmental communi ties over traces of xenobiotics in foods and in both abiotic and biotic envi ronments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published research papers and progress reports, and archival documentations. These three international publications are integrated and scheduled to provide the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. This series is reserved ex clusively for the diversified literature on "toxic" chemicals in our food, our feeds, our homes, recreational and working surroundings, our domestic animals, our wildlife and ourselves. Tremendous efforts worldwide have been mobilized to evaluate the nature, presence, magnitude, fate, and toxi cology of the chemicals loosed upon the earth. Among the sequelae of this broad new emphasis is an undeniable need for an articulated set of authoritative publications, where one can find the latest important world literature produced by these emerging areas of science together with docu mentation of pertinent ancillary legislation. Research directors and legislative or administrative advisers do not have the time to scan the escalating number of technical publications that may contain articles important to current responsibility. Rather, these individu als need the background provided by detailed reviews and the assurance that the latest information is made available to them, all with minimal literature searching."
This richly-illustrated reference guide presents innovative techniques focused on reducing time, cost and risk in the construction and maintenance of underground facilities: A primary focus of the technological development in underground engineering is to ease the practical execution and to reduce time, cost and risk in the construction and maintenance of underground facilities such as tunnels and caverns. This can be realized by new design tools for designers, by instant data access for engineers, by virtual prototyping and training for manufacturers, and by robotic devices for maintenance and repair for operators and many more advances. This volume presents the latest technological innovations in underground design, construction, and operation, and comprehensively discusses developments in ground improvement, simulation, process integration, safety, monitoring, environmental impact, equipment, boring and cutting, personnel training, materials, robotics and more. These new features are the result of a big research project on underground engineering, which has involved many players in the discipline. Written in an accessible style and with a focus on applied engineering, this book is aimed at a readership of engineers, consultants, contractors, operators, researchers, manufacturers, suppliers and clients in the underground engineering business. It may moreover be used as educational material for advanced courses in tunnelling and underground construction.
This monograph provides a comprehensive state-of-the-art
description of the work carried out in the UK and Japan on "Flow
and Sediment Transport in Compound Channels." It therefore
describes research which has been conducted, primarily over the
last two decades, and which has yielded a fairly detailed picture
of the important behaviours of compound channels and produced a
number of engineering prediction methods which ought to be widely
adopted in practice. The text will inevitably highlight areas where
our knowledge is sparse and it will spur others on in the task of
filling in such gaps.

The need to produce food without the destructive chemical horrors of much modern farming, for an intelligent use of dwindling natural resources and for humane forms of production is universal, the practice is limited. This book is an account of one, large, instance of success in practice. Twenty-five years ago, Winin Pereira, a nuclear physicist abandoned academia to start a co-operative farm at Alonde in a tribal area north of Bombay. The group experienced, and finally discarded, all the false hopes and promises of Western originated forms of development: ploughs that ploughed too deep, irrigation systems that lowered water tables, fertilizers and pesticides which managed the earth and became so expensive that poorer farmers were dispossessed. Instead they learnt from the adivasai, or tribal people, who have nurtured or been nurtured by foresets for millennia, ways of applying popular knowledge to contemporary problems. This book is a combination of Pereira's record of achievement of sustainable livelihoods and an account of the farm and its effect on the India around it by a leading British journalist. Originally published in 1991
Lands lost to desert may effectively be lost for ever, so desertification is humanity's most obvious despoliation to the planet. It is certainly one of the most serious environmental problems facing the world today. In this book the author describes what is happening and where. Although the problem is greatest in developing countries, it is by no means confined to them. Australia, Africa, the USA and India are all affected. In the 1970s an international Plan of Action was drawn up to bring the phenomenon under control, but it was never implemented. Now that the situation is more serious than ever before, this book urges new action and describes many of the myriad ways in which it is possible to arrest the progress of desertification. It describes, too, not just the failures, but the considerable successes that have been achieved. Originally published in 1990
In 1990, energy in the UK underwent a unique and fundamental transformation, with the privatization of the electricity supply industry. This is the first book to fully assess the experiment. It first explains how - and why - the British electricity supply industry was privatized. It then identifies the subsequent changes in electricity prices, profits, employment, investment, nuclear power and renewable, and the extent to which each of these was due solely to privatization or to other factors, or could have come about by reform of the previous model, rather than privatization. Finally, the authors analyse the key unresolved issues of regulation, introducing competition into the domestic energy market in 1998, supply security, and other long-term strategic considerations. Throughout, the distinguish between the uniquely British elements of the experience and those which can be drawn upon by other countries embarking upon similar reforms. Today, governments throughout the world are looking to the UK's experience as a potential prototype for the restructure of their own electricity supply industries. For them, and for electricity utilities, fuel and power plant suppliers, regulation authorities, financial analysts, international agencies, journalists and academics alike, this thorough and pragmatic study will be essential reading. 'This is likely to become the definitive book on the first six years of the great British electricity experiment' Walt Patterson The British Electricity Experiment is the result of a detailed study undertaken by the Energy Programme at the science Policy Research unit (SPRU). Professor John Surrey was head of SPR's Energy Programme between 1969 and 1986. He has worked with the central Electricity Generating Board, as a government Economic Adviser, and as a Specialist Adviser to numerous House of Commons Select Committee inquiries on energy matters.

Most of the world's population lives on or near the coasts. Every nation not completely landlocked has used the sea as its supposedly self-cleansing garbage dump. Now the effects are being felt. There is not a coast in the world which is not dangerously polluted. Sewage, oil, plastics, industrial effluents, radioactive waste have been added to ungoverned development, all of which are busily destroying otherwise robust inshore eco-systems. Hinrichsen, basing his work on United Nations Environment Programme (UNEP) research and his own extensive travels, has described the situation in the Mediterranean, the Gulf, the Indian Ocean, the South-East Asian Seas and the Eastern Pacific. He covers both the disasters and the growing successes in dealing with them, and he points the way to the sort of international deal needed to rescue a vast resource in danger of complete destruction. His book is both a call to action and a sign of hope.Originally published in 1990
Tomatoes could not be grown commercially without the help of their wild relatives. A single wild species of rice has helped double rice production in Asia. Wild silk-worms are enabling India to expand its silk industry. A wild carp with resistance to cold has been used to extend Soviet carp production further into the north. Wild genetic resources - the heritable characteristics of wild plants and animals - are used increasingly to improve domesticated crops and livestock and as new sources of food and of raw materials. But habitat destruction, over-exploitation and competition from introduced species is destroying many gene pools even before they have been identified. Genes from the Wild describes the growing contribution of wild genetic resources to the production of food and raw materials, describes their characteristics, explains the benefits and problems of using them and outlines the ways in which they are threatened and the measures being taken to conserve them. Originally published in 1988
The changing climate, the warming of the world and acid rain are among the greatest problems facing us at the end of the twentieth century. This book describes, for the first time, the effects of these phenomena on the high mountains and the forests of Europe. Mountains and the frozen regions (the cryosphere) not only play a major part in our climatic system, but are also central to our water supplies. Yet our glaciers are shrinking, our lakes and soils are becoming acidified, our forests are damaged and the whole fragile ecosystem of ranges like the Alps and the Caucasus is threatened. Nilsson and Pitt present the evidence and assess the probable effects of these changes on mountain society, tourism, water, flora and fauna. They also examine the uncertainties. Above all they look, too, at the best possible strategies in response to What is happening and at what the next steps should be. Originally published in 1991 |
