Continuum Mechanics Modeling of Material Behavior offers a uniquely comprehensive introduction to topics like RVE theory, fabric tensor models, micropolar elasticity, elasticity with voids, nonlocal higher gradient elasticity and damage mechanics. Contemporary continuum mechanics research has been moving into areas of complex material microstructural behavior. Graduate students who are expected to do this type of research need a fundamental background beyond classical continuum theories. The book begins with several chapters that carefully and rigorously present mathematical preliminaries: kinematics of motion and deformation; force and stress measures; and general principles of mass, momentum and energy balance. The book then moves beyond other books by dedicating several chapters to constitutive equation development, exploring a wide collection of constitutive relations and developing the corresponding material model formulations. Such material behavior models include classical linear theories of elasticity, fluid mechanics, viscoelasticity and plasticity. Linear multiple field problems of thermoelasticity, poroelasticity and electoelasticity are also presented. Discussion of nonlinear theories of solids and fluids, including finite elasticity, nonlinear/non-Newtonian viscous fluids, and nonlinear viscoelastic materials are also given. Finally, several relatively new continuum theories based on incorporation of material microstructure are presented including: fabric tensor theories, micropolar elasticity, elasticity with voids, nonlocal higher gradient elasticity and damage mechanics.

Estuaries are natural highly dynamic and rapidly changing systems, comprising a complex combination of physical processes on many different time- and space- scales. The research conducted a systematic study on the topic of fine sediment physical processes in a meso-tidal convergent alluvial estuary. By means of multi-approaches (field survey, laboratory experiment and numerical modeling) and from multi-angles (data-driven analysis and process-based modeling) we highlight that multiscale (including micro- and macro- scale) physical processes jointly characterize the current and sediment regime in a fine sediment estuarine system. The study presented in this book investigates micro- and macro- scale physical processes of a large-scale fine sediment estuarine system with a moderate tidal range as well as a highly seasonal-varying freshwater inflow. Based on a series of measured, experimented and modelled data, the research highlights that (i) along-channel fresh-salt gradient near an estuarine turbidity maximum zone is a key parameter controlling local density stratification and sedimentation in the channel; (ii) the salinity-induced baroclinic pressure gradient forces are a major factor impacting internal velocity and suspended sediment concentration (SSC) structures; (iii) vertical profiles of current, salinity and SSC within a river plume are dependent on a correct prediction of the development of turbulence; (iv) both suspended particulate matter availability and local residual flow regime are of critical importance for trapping probability of sediment and the occurrence of fluid mud; (v) river discharge impacts the horizontal and vertical distribution of residual current; (vi) seasonally varying wind effect alters the residual currents near the riverine limit; (vii) seasonally varied mean sea level and wind climate jointly shape the saltwater intrusion length near the estuarine front.

Validation of Dynamic Analyses of Dams and Their Equipment is the outcome of a three year cooperation program between CFBR (Comite Francais des Barrages et Reservoirs or French Committee on Large dams) and JCOLD (Japan Commission on Large Dams), and focusses on the dynamic behavior of concrete and embankment dams analyzed based on acceleration records of the JCOLD data base. The book covers a broad range of topics, including simplified and detailed methods of dynamic analysis for the seismic response of concrete and embankment dams compared with measured behavior. The response of embankment dams subjected to a 1.0 g foundation acceleration time history is computed by several analytical methods and compared. The modelling of stress-strain behavior of compacted soils for seismic stability analysis of earth-fill dams and its application for a failed earthfill dam is described. The cracking of the face slab of four faced rockfill dams during earthquakes is analyzed. The seismic behavior of concrete arch dams is discussed by the comparison of numerical and experimental results. Displacement-based seismic assessment of concrete dams is presented. Finally the book contains a comparison between the Japanese and French design criteria of gates and a comparison of the analysis of gates and field measurements. Validation of Dynamic Analyses of Dams and Their Equipment will be useful to professional and academics involved or interested in dam engineering.

Water is one of the most precious and basic needs of life for all living beings, and a precious national asset. Without it, the existence of life cannot be imagined. Availability of pure water is decreasing day by day, and water scarcity has become a major problem that is faced by our society for the past few years. Hence, it is essential to find and disseminate the key solutions for water quality and scarcity issues. The inaccessibility and poor water quality continue to pose a major threat to human health worldwide. Around billions of people lacking to access drinkable water. The water contains the pathogenic impurities; which are responsible for water-borne diseases. The concept of water quality mainly depends on the chemical, physical, biological, and radiological measurement standards to evaluate the water quality and determine the concentration of all components, then compare the results of this concentration with the purpose for which this water is used. Therefore, awareness and a firm grounding in water science are the primary needs of readers, professionals, and researchers working in this research area. This book explores the basic concepts and applications of water science. It provides an in-depth look at water pollutants' classification, water recycling, qualitative and quantitative analysis, and efficient wastewater treatment methodologies. It also provides occurrence, human health risk assessment, strategies for removal of radionuclides and pharmaceuticals in aquatic systems. The book chapters are written by leading researchers throughout the world. This book is an invaluable guide to students, professors, scientists and R&D industrial specialists working in the field of environmental science, geoscience, water science, physics and chemistry.

Rivers are important agents of change that shape the Earth's surface and evolve through time in response to fluctuations in climate and other environmental conditions. They are fundamental in landscape development, and essential for water supply, irrigation, and transportation. This book provides a comprehensive overview of the geomorphological processes that shape rivers and that produce change in the form of rivers. It explores how the dynamics of rivers are being affected by anthropogenic change, including climate change, dam construction, and modification of rivers for flood control and land drainage. It discusses how concern about environmental degradation of rivers has led to the emergence of management strategies to restore and naturalize these systems, and how river management techniques work best when coordinated with the natural dynamics of rivers. This textbook provides an excellent resource for students, researchers, and professionals in fluvial geomorphology, hydrology, river science, and environmental policy.

The swelling of concrete is a major concern for the owners and operators of dams and hydraulic structures. Faced with irreversible movement of their dams or with observations of cracking processes, operators need to explain the phenomena observed in order to justify safety conditions and in some cases to plan remedial works. Over the last 20 years, active research has been carried out in the field, resulting in practical results in phenomena interpretation and dam modeling. At the same time, an increasing number of affected dams have undergone safety re-evaluations and in some cases remedial work. Several of them have been removed altogether. Although it remains difficult to establish a state of the art in this domain due to the rapidly changing context, regular international exchanges in the field appear fruitful and necessary. Following on from previous conferences in the field organized by Robin Charlwood, former President of the ICOLD Concrete Committee, the initiative was taken by EDF and Toulouse University-LMDC to organize a workshop to provide a new opportunity for sharing experience. The aim of this workshop is to assemble active researchers, leading engineers, and experts from the practicing community and administration interested directly or indirectly in concrete swelling effects in dams and hydraulic structures. All types of chemical expansion phenomena, including those due to alkali aggregate reactions and those due to ettringite formation, are addressed. This book is written by experts renowned in their field, illustrating the need to progress with interdisciplinary approaches.

The construction of the Crossrail project began at North Dock in Canary Wharf in May 2009. At the height of construction it was the biggest railway construction project in Europe and is one of the largest single infrastructure investments undertaken in the UK. It consists of 21 km of new twin-bore tunnels under central London and 10 new world-class stations across one of the largest cities in the world. Crossrail Project: Infrastructure Design and Construction Volume 6 contains a collection of 22 papers submitted to the 2021 Crossrail's Technical Papers Competition. Contributions have come from members of the Crossrail organisation, its consultants as well as contractors involved in design and construction across the Crossrail project. The papers cover a multitude of disciplines including tunnelling, geotechnical engineering, rail signalling and control, rail systems & integration, rail telecommunications, and electrical engineering. As part of the enduring legacy of the Crossrail project, it is incumbent upon the organisation to share its experiences and best practices with the rest of the industry, to showcase the skills of the personnel involved and the successful delivery of each phase of works. Crossrail Project: Infrastructure Design and Construction Volume 6 offers more high-quality papers on the best practice in design and construction for large-scale underground projects.

Since the first implementation by Electricite de France on the Goulours dam (France) in 2006, the Piano Key Weir has become a more and more applied solution to increase the discharge capacity of existing spillways. In parallel, several new large dam projects have been built with such a flood control structure, usually in combination with gates. Today, more than 25 Piano Key Weirs are in operation or under construction all over the world. More than 15 years of research and development have enabled detailed investigations of the hydraulic and structural behaviour of the Piano Key Weir complex structure and have provided more and more accurate design equations. Following the proceedings of the first two workshops held in Liege (Belgium - 2011) and Paris (France - 2013), Labyrinth and Piano Key Weirs III collects the contributions presented by people with varied background, from researchers to practitioners, at the 3rd International Workshop on Labyrinth and Piano Key Weirs - PKW 2017 (22-24 February 2017, Qui Nhon, Vietnam). The papers, reviewed and accepted by an International Scientific Committee, summarize the current state-of-the-art on Piano Key Weirs from a theoretical to a practical point of view, and present most of the main projects in operation or under construction. Labyrinth and Piano Key Weirs III is thus a reference for students, practitioners and researchers interested in Dams Engineering.

Computers are increasingly used in the simulation of natural phenomena such as floods. However, these simulations are based on numerical approximations of equations formalizing our conceptual understanding of flood flows. Thus, model results are intrinsically subject to uncertainty and the use of probabilistic approaches seems more appropriate. Uncertain, probabilistic floodplain maps are widely used in the scientific domain, but still not sufficiently exploited to support the development of flood mitigation strategies. In this thesis the major sources of uncertainty in flood inundation models are analyzed, resulting in the generation of probabilistic floodplain maps. The utility of probabilistic model output is assessed using value of information and the prospect theory. The use of these maps to support decision making in terms of floodplain development under flood hazard threat is demonstrated.

In an increasingly urbanized world, water systems must be designed and operated according to innovative standards in terms of climate adaptation, resource efficiency, sustainability and resilience. This grand challenge triggers unprecedented questions for hydro-environment research and engineering. Shifts in paradigms are urgently needed in the way we view (circular) water systems, water as a renewable energy (production and storage), risk management of floods, storms, sea level rise and droughts, as well as their consequences on water quality, morphodynamics (e.g., reservoir sedimentation, scour, sustainability of deltas) and the environment. Addressing these issues requires a deep understanding of basic processes in fluid mechanics, heat and mass transfer, surface and groundwater flow, among others.

A book centring on late Anglo-Saxon and Anglo-Norman canals may come as a surprise; it is generally assumed that no such things existed. Persuasive evidence has, however, been unearthed independently by several scholars, and has stimulated this first serious study of improved waterways in England between the eleventh and fourteenth centuries. England is naturally well-endowed with a network of navigable rivers, especially the easterly systems draining into the Thames, Wash, and Humber. The central middle ages saw innovative and extensive development of this network, including the digging of canals bypassing difficult stretches of rivers, or linking rivers to important production centres. The eleventh and twelfth centuries seem to have been the high point for this dynamic approach to water-transport: after 1200, the improvement of roads and bridges increasingly diverted resources away from the canals, many of which stagnated with the reassertion of natural drainage patterns. This new perspective has an important bearing on the economy, landscape, settlement patterns, and inter-regional contacts of medieval England. In this volume, economic historians, geographers, geomorphologists, archaeologists, and place-name scholars bring their various skills to bear on a neglected but important aspect of medieval engineering and economic growth.

In past decades, urban water management practices focused on optimizing the design and operation of water distribution networks, wastewater collection systems, and water and wastewater treatment plants. However, municipalities are now faced with aging urban water infrastructures whose operation must be improved and expanded to maintain current high standards of living as well as new challenges such as climate change, systems sustainability and water quality issues. Integrating the latest developments in urban water hydrology and management, Urban Water Engineering and Management takes a system approach to urban water hydrology, engineering, planning and management, supplying examples and case studies and highlighting pressing issues such as urban water governance, disaster management, and climate change impacts on urban areas. The book draws attention to climate change as a main concern of this century by focusing on its impact the components of water cycle.

The book covers modeling of urban water cycle components, urban water supply, and distribution systems demand forecasting. It also presents classical issues, such as design of water distribution networks and wastewater and storm collection in urban settings, from a system's perspective. The text also includes a discussion of water governance and disaster management in urban areas and the urbanization effects on the environment and the needed water infrastructure development in urban areas. Against this background, the authors discuss the importance of understanding the principles of simulation, optimization, multiple-criterion decision making, and conflict resolution for successful, integrated urban water management. They explore integrated water management and planning solutions for incorporating structural and nonstructural means to achieve the best operational schemes at affordable costs, going beyond using the existing structures and physical limitations on water availability to include technical, social, political, and economic aspects of better water and wastewater management in urban areas.

Written and designed especially for intermediate and advanced courses/modules in water resources in civil and environmental engineering, and in urban planning, the book can be used as a textbook for civil engineering, urban and regional planning, geography, environmental science, and in courses dealing with urban water cycle. It also introduces new horizons for engineers as well as policy and decision makers who plan for future urban water and regional sustainability. Engineers and planners, especially those who work on design, planning, and management of urban systems and/or community development, can use this book in practice because it deals with a broad range of real world urban water problems.

This book explores many recent techniques including ANN, fuzzy logic, hydraulic models and IWRM utilized for integrated water resources management, a real challenge in India for obtaining high irrigation efficiency. The book deals with topics of current interest, such as climate change, floods, drought, and hydrological extremes. The impact of climate change on water resources is drawing worldwide attention these days; for water resources, many countries are already stressed and climate change along with burgeoning population, rising standard of living, and increasing demand are adding to the stress. Further, river basins are becoming less resilient to climatic vagaries. Fundamental to addressing these issues is hydrological modelling which is covered in this book Further, integrated water resources management is vital to ensure water and food security. Integral to the management is groundwater and solute transport. The book encompasses tools that will be useful to mitigate the adverse consequences of natural disasters.

Humanity is deeply committed to living along the world's shores, but a catastrophic storm like Sandy - which took hundreds of lives and caused many billions of dollars in damages - shines a bright light at how costly and vulnerable life on a shoreline can be. Taking Chances offers a wide-ranging exploration of the diverse challenges of Sandy and asks if this massive event will really change how coastal living and development is managed. Bringing together leading researchers - including biologists, urban planners, utilities experts, and climatologists, among others - Taking Chances illuminates reactions to the dangers revealed by Sandy. Focusing on New Jersey, New York, and other hard-hit areas, the contributors explore whether Hurricane Sandy has indeed transformed our perceptions of coastal hazards, if we have made radically new plans in response to Sandy, and what we think should be done over the long run to improve coastal resilience. Surprisingly, one essay notes that while a large majority of New Jerseyans identified Sandy with climate change and favored carefully assessing the likelihood of damage from future storms before rebuilding the Shore, their political leaders quickly poured millions into reconstruction. Indeed, much here is disquieting. One contributor points out that investors scared off from further investments on the shore are quickly replaced by new investors, sustaining or increasing the overall human exposure to risk. Likewise, a study of the Gowanus Canal area of Brooklyn shows that, even after Sandy swamped the area with toxic flood waters, plans to convert abandoned industrial lots around the canal into high-density condominiums went on undeterred. By contrast, utilities, emergency officials, and others who routinely make long-term plans have changed operations in response to the storm, and provide examples of adaptation in the face of climate change. Will Sandy be a tipping point in coastal policy debates - or simply dismissed as a once-in-a-century anomaly? This thought-provoking collection of essays in Taking Chances makes an important contribution to this debate.
