As urban areas keep growing, water infrastructure ages, and the requirements on environmental protection become more rigorous, there is a continual need for upgrading water pollution control facilities and restoring degraded urban waters. Such issues are addressed in this book by focusing on five major topics: (a) Upgrading stormwater management facilities, (b) Retrofitting / upgrading combined sewer overflow (CSO) facilities, (c) Optimising/upgrading sewage treatment plant performance, (d) Urban stream restoration, and (e) Challenges in restoring urban environment. Each chapter contains some overview papers followed by research or case study papers. Besides presentations of new approaches and accomplishments in the field of upgrading and restoration, several papers provide analysis of vast needs in this field in several countries of Central and Eastern Europe, which either recently joined the European Union (EU) or are preparing for accession, and need to comply with the existing EU directives dealing with environmental protection. As such, this book will be of primary interest to researchers and university lecturers dealing with environmental upgrading and restoration, environmental planners from all levels of government, municipal engineers and politicians, and finally the private industry representatives (consultants, private utilities and environmental technology suppliers) searching for new business opportunities among the new or aspiring members of EU.

The fusion of algebra, analysis and geometry, and their application to real world problems, have been dominant themes underlying mathematics for over a century. Geometric algebras, introduced and classified by Clifford in the late 19th century, have played a prominent role in this effort, as seen in the mathematical work of Cartan, Brauer, Weyl, Chevelley, Atiyah, and Bott, and in applications to physics in the work of Pauli, Dirac and others. One of the most important applications of geometric algebras to geometry is to the representation of groups of Euclidean and Minkowski rotations. This aspect and its direct relation to robotics and vision will be discussed in several chapters of this multi-authored textbook, which resulted from the ASI meeting. Moreover, group theory, beginning with the work of Burnside, Frobenius and Schur, has been influenced by even more general problems. As a result, general group actions have provided the setting for powerful methods within group theory and for the use of groups in applications to physics, chemistry, molecular biology, and signal processing. These aspects, too, will be covered in detail. With the rapidly growing importance of, and ever expanding conceptual and computational demands on signal and image processing in remote sensing, computer vision, medical image processing, and biological signal processing, and on neural and quantum computing, geometric algebras, and computational group harmonic analysis, the topics of the book have emerged as key tools. The list of authors includes many of the world's leading experts in the development of new algebraic modeling and signal representation methodologies, novel Fourier-based and geometric transforms, and computational algorithms required for realizing the potential of these new application fields.

The European DayWater project has developed a prototype of an Adaptive Decision Support System (ADSS) related to urban stormwater pollution source control. The DayWater ADSS greatly facilitates decision-making for stormwater source control, which is currently impeded by the large number of stakeholders involved and by the necessary multidisciplinary knowledge. This book presents the results of this project, providing new insights into both technical and management issues. The main objectives of its technical chapters are pollution source control modelling, risk and impact assessment, and evaluation and comparison of best management practices. It also covers management aspects, such as the analysis of the decision-making processes in stormwater source control, at a European scale, and stormwater management strategies in general. The combination of scientific-technical and socio-managerial knowledge, with the strong cooperation of numerous end-users, reflects the innovative character of this book which includes actual applications of the ADSS prototype in significant case studies. DayWater: an Adaptive Decision Support System for Urban Stormwater Management contains 26 chapters collectively prepared by DayWater scientific partners and end-users associated with this European Research and Development project. It includes: A general presentation of the DayWater Adaptive Decision Support System (ADSS) structure and operation modes A detailed description of the major components of this ADSS prototype The assessment of its components in significant case studies in France, Germany and Sweden The proceedings of the International Conference on Decision Support Systems for Integrated Urban Water Management, held in Paris on 3-4 November 2005. The book presents the ADSS prototype including a combination of freely accessible on-line databases, guidance documents, “road maps” and modelling or multi-criteria analysis tools. As demonstrated in several significant case studies the challenge for stormwater managers is to make the benefits of urban stormwater management visible to society, resulting in active co-operation of a diversity of stakeholders. Only then, will sustainable management succeed. DayWater: an Adaptive Decision Support System for Urban Stormwater Management advances this cause of sustainable urban management through Urban stormwater management, and makes achievable (by means of risk and vulnerability tools which are included) the goal of integrated urban water management (IUWM).

On Friday, January 28, 1977, it began to snow in Buffalo. The second largest city in New York State, located directly in line with the Great Lakes’ snowbelt, was no stranger to this kind of winter weather. With their city averaging ninety-four inches of snow per year, the citizens of Buffalo knew how to survive a snowstorm. But the blizzard that engulfed the city for the next four days was about to make history. Between the subzero wind chill and whiteout conditions, hundreds of people were trapped when the snow began to fall. Twenty- to thirty-foot-high snow drifts isolated residents in their offices and homes, and even in their cars on the highway. With a dependency on rubber-tire vehicles, which lost all traction in the heavily blanketed urban streets, they were cut off from food, fuel, and even electricity. This one unexpected snow disaster stranded tens of thousands of people, froze public utilities and transportation, and cost Buffalo hundreds of millions of dollars in economic losses and property damages. The destruction wrought by this snowstorm, like the destruction brought on by other natural disasters, was from a combination of weather-related hazards and the public policies meant to mitigate them. Buffalo’s 1977 blizzard, the first snowstorm to be declared a disaster in US history, came after a century of automobility, suburbanization, and snow removal guidelines like the bare-pavement policy. Kneeland offers a compelling examination of whether the 1977 storm was an anomaly or the inevitable outcome of years of city planning. From the local to the state and federal levels, Kneeland discusses governmental response and disaster relief, showing how this regional event had national implications for environmental policy and how its effects have resounded through the complexities of disaster politics long after the snow fell.

The Alaska Department of Transportation and Public Facilities (AKDOT & PF) lacks guidance regarding Best Management Practices (BMPs) for centralized snow storage sites receiving snow from highway maintenance in Alaska. Interviews with AKDOT & PF characterized snow maintenance and operations practices across the climatological regions of Alaska. A literature search yielded many potential BMPs, which were evaluated for suitability based upon ability to treat deposits of variable size and frequency; deposits with high concentrations of solids, debris, and chemical contaminants; initial and maintenance costs; applicability to environmentally sensitive areas; and technology history. A review of potential regulations and interviews with representatives from regulatory agencies generated regulatory needs for each BMP type. Input from AKDOT & PF was used to create a final listing of potential BMPs. Additionally, the technical, economic, and regulatory feasibility of direct disposal to surface waters is reviewed.

URBAN WATER INFRASTRUCTURE NATO ADVANCED RESEARCH WORKSHOP SUMMARY 22-27 JUNE 1989 KYLE E SCHILLING P E Workshop Director The Workshop was based on the recognition that all NATO countries are concerned with similar water infrastructure issues. Present problems are aggravated by aging and neglected facilities, by inadequate financing and by water management institutions reflecting the needs of an earlier era. Service needs to be provided for expanding populations, at the same time that corrective measures must be taken for decaying older urban centers, resulting both from neglect and expiring service life. These needs exist within the framewode of other competing and conflicting uses for existing and yet to be developed water sources. The problems have generated some highly visible national debates over financing due to the large sums involved. Despite differences in the age of the North American, European and other societies, the technological ages of water supply and storm water systems are much the same and provide a common denominator in the worldwide trend to urbanization. Examination of approaches to urban water management also indicates that they are generally based on past experience and institutions created in a non-urban era. The physical, financial and institutional alternatives are consequently often out-of-step with current urban environment. Historically, the supply of adequate water and efficient storm water management have also been top priority items with water quality and other aspects of environmental protection assuming a lower priority after basic supply needs have been met.
