DOWNLOAD EBOOKThe WATER SUPPLY volume discerned a consistent pattern of under-pricing and over-building. Rational reallocation of existing supplies, such as would occur if prices were raised in response to scarcity, is almost never even considered as an alternative to new construction. There are several reasons, aside from the electoral attractiveness of water projects. (1) Politically determined prices are inflexible. New York, for example, has not modified its price schedule since 1933. (Of course, had the city attempted to do something about prices in the 1965 shortage they would have run into conflict with the CEA 'guide-lines'). (2) A higher-order political rigidity makes it commonly impossible for one water jurisdiction to sell title or rights to another -- hence an incentive to rush into construction to nail down the supplies involved. (3) Certain errors in economic reasoning have played a role: Ignorance of the marginal principle, double-counting of benefits, the use of inappropriately low discount rates, etc. But these analytical errors have had much less practical significance than what might be called the non-analytical error. This is the belief, usually quite unconscious, that there are 'needs' or 'requirements' for water rather than economic demands.

DOWNLOAD EBOOKThis book examines changes and transitions in the way water is managed in urban environments. This book originated from a joint French-Australian initiative on water and land management held in Montpellier, France. The book delivers practical insights into urban water management. It links scientific insights of researchers with the practical experiences of urban water practitioners to understand and respond to key trends in how urban water is supplied, treated and consumed. The 51 contributors to the volume provide a range of insights, case studies, summaries and analyses of urban water and from a global perspective. The first section on water supply and sanitation includes case studies from Zimbabwe, France and South Africa, among others. Water demand and water economics are addressed in the second section of the book, with chapters on long-term water demand forecasting, the social determinants of water consumption in Australian cities, a study of water quality and consumption in France, governance and regulation of the urban water sector and more. The third section explores water governance and integrated management, with chapters on water management in Quebec, in the Rotterdam-Rijnmond urban area, in Singapore and in Australia. The final section offers perspectives on challenges and future uncertainties for urban water systems in transition. Collectively, the diverse insights provide an important step forward in response to the challenges of sustainably delivering water safely, efficiently and equitably.

DOWNLOAD EBOOKThe history behind our growing water crisis: “A gem . . . An erudite romp through two millennia of water and sanitation practice and technology.” —Nature Turn on the faucet, and water pours out. Pull out the drain plug, and the dirty water disappears. Most of us give little thought to the hidden systems that bring us water and take it away when we’re done with it. But these underappreciated marvels of engineering face an array of challenges that cannot be solved without a fundamental change to our relationship with water, David Sedlak explains in this enlightening book. To make informed decisions about the future, we need to understand the three revolutions in urban water systems that have occurred over the past 2,500 years, and the technologies that will remake the system. The author starts by describing Water 1.0, the early Roman aqueducts, fountains, and sewers that made dense urban living feasible. He then details the development of clean drinking water and sewage treatment systems—the second and third revolutions in urban water. He offers an insider’s look at current systems that rely on reservoirs, underground pipe networks, treatment plants, and storm sewers to provide water that is safe to drink, before addressing how these water systems will have to be reinvented. For everyone who cares about reliable, clean, abundant water, this book is essential reading.

DOWNLOAD EBOOKDeveloping an improved understanding of emerging flood risk management and urban water management was the goal set for research presented at the 6th International Conference on Flood and Urban Water Management, held in A Coruña, Spain. The published papers look to solve various challenges in this field by drawing on the expertise of numerous disciplines and considering a range of responses. Flooding is a global phenomenon that claims numerous lives worldwide each year. When flooding occurs in urban areas, it can cause substantial damage to property as well as threaten human life. In addition, many more people must endure the homelessness, upset and disruption that are left in the wake of floods. The increased frequency of flooding in the last few years, coupled with climate change predictions and urban development, suggest that these impacts are set to worsen in the future. How we respond and importantly, adapt to these challenges is key to developing our long-term resilience at the property, community and city scale. Apart from the physical damage to buildings, contents and loss of life, which are the most obvious, impacts of floods upon households, other more indirect losses are often overlooked. These indirect and intangible impacts are generally associated with disruption to normal life as well as long-term health issues including community displacements and stress-related illnesses. Flooding represents a major barrier to the alleviation of poverty in many parts of the developing world, where vulnerable communities are often exposed to sudden and life-threatening events. As our cities continue to expand, their urban infrastructures need to be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanization. The papers contained in this book consider these problems and deals with two main urban water topics: water supply systems and urban drainage.

DOWNLOAD EBOOKUrban Water III is the proceedings of the 3rd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems. The conference reconvened following its success in 2012 and in 2014, when it was held in the Algarve, Portugal. These proceedings deal with two main subjects: water supply systems and urban drainage. Water distribution networks often suffer substantial losses which indicate energy and treatment waste. Sewer systems are under relentless pressure due to urbanisation and climate change, and the environmental impact caused by urban drainage overflows is related to both water quantity and water quality. Most architects and town planners are aware of the importance of the interaction between urban water cycles and city planning and landscaping. Specialised computer tools are needed to manage all of these aspects and are required to respond to the increased complexity of urban water systems. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Other related topics include: Leakage and losses; Modelling and experimentation; Safety and security of water systems; Maintenance and repairs; Surface water and groundwater sources; Reservoirs; Network design; Waste water treatment and disposal; Combined sewer networks; Flood control; Storage tanks; Environmental impact; Domestic and industrial waste water issues. In addition to the above, the conference discusses legal and regulatory aspects, along with more technical problems.

DOWNLOAD EBOOKUrban Water II is the proceedings of the 2nd International Conference on the Design, Construction, Maintenance, Monitoring and Control of Urban Water Systems. The meeting was reconvened following the success of the first conference held in the New Forest, home to the Wessex Institute of Technology in 2012. Water systems in the urban environment consist of supply networks as well as sewage and storm drainage systems. They interact with each other and with warm bodies such as rivers, lakes and aquifers, and this interaction affects the quality and quantity of the different systems. As our cities continue to expand, their urban infrastructure must be re-evaluated and adapted to new requirements related to the increase in population and the growing areas under urbanisation. New water systems are also required to reduce the risk associated with floods, network failures and many others related to inadequate networks. New systems should reduce economic losses and environmental impacts as well as promote a higher degree of reliability. Improved management, measurement and control mechanisms are needed to ensure the efficiency and safety of urban water systems. Topics such as contamination and pollution discharges in urban water bodies, as well as the monitoring of water recycling systems are currently receiving a great deal of attention from researchers and professional engineers working in the water industry. Architects and town planners are also aware of the importance of the interaction between urban water cycles and city planning and landscaping. Management of all these aspects requires the development of specialised computer tools that can respond to the increased complexity of urban water systems. Relating to the subject areas of Water supply networks and Urban Drainage, topics covered include: Leakage and losses; Modelling and experimentation; Safety and security of water systems; Maintenance and repairs; Water quality; Water savings and reuse; Surface water and groundwater sources; Reservoirs; Network design; Waste water treatment and disposal; Structural works and infrastructure; Water quality issues; Combined sewer networks; Flood control; Storage tanks; Environmental impact; Domestic and industrial waste water issues.

DOWNLOAD EBOOKThis comprehensive introduction to rock mechanics treats the basics of rock mechanics in a clear and straightforward manner and discusses important design problems in terms of the mechanics of materials. This extended second edition includes an additional chapter on Rock Bursts and Bumps, a part on Basics Dynamics, and has numerous additional examples and exercises throughout the chapters. Developed for a complete class in rock engineering, this volume uniquely combines the design of surface and underground rock excavations and addresses: • rock slope stability in surface excavations, from planar block and wedge slides to rotational and toppling failures • shaft and tunnel stability, ranging from naturally-supported openings to analysis and design of artificial support and reinforcement systems • entries and pillars in stratified ground • three-dimensional caverns, with emphasis on cable bolting and backfill • geometry and forces of chimney caving, combination support and trough subsidence • rock bursts and bumps in underground excavations, with focus on dynamic phenomena and on fast and sometimes catastrophic failures. The numerous exercises and examples familiarize the reader with solving basic practical problems in rock mechanics through various design analysis techniques and their applications. Supporting the main text, appendices provide supplementary information about rock, joint, and composite properties, rock mass classification schemes, useful formulas, and an extensive literature list. The large selection of problems at the end of each chapter can be used for home assignment. A solutions manual is available to course instructors. Explanatory and illustrative in character, this volume is suited for courses in rock mechanics, rock engineering and geological engineering design for undergraduate and first year graduate students in mining, civil engineering and applied earth sciences. Moreover, it will form a good introduction to the subject of rock mechanics for earth scientists and engineers from other disciplines.

DOWNLOAD EBOOKWater is a global resource for modern societies - and water was a global resource for pre-modern societies. The many different water systems serving processes of urbanisation and urban life in ancient times and the Middle Ages have hardly been researched until now. The numerous contributions to this volume pose questions such as what the basic cultural significance of water was, the power of water, in the town and for the town, from different points of view. Symbolic, aesthetic, and cult aspects are taken up, as is the role of water in politics, society, and economy, in daily life, but also in processes of urban planning or in urban neighbourhoods. Not least, the dangers of polluted water or of flooding presented a challenge to urban society. The contributions in this volume draw attention to the complex, manifold relations between water and human beings. This collection presents the results of an international conference in Kiel in 2018. It is directed towards both scholars in ancient and mediaeval studies and all those interested in the diversity of water systems in urban space in ancient and mediaeval times.
