Understanding how to properly manage urban stormwater is a critical concern to civil and environmental engineers the world over. Mismanagement of stormwater and urban runoff results in flooding, erosion, and water quality problems. In an effort to develop better management techniques, engineers have come to rely on computer simulation and advanced mathematical modeling techniques to help plan and predict water system performance. This important book outlines a new method that uses probability tools to model how stormwater behaves and interacts in a combined- or single-system municipal water system. Complete with sample problems and case studies illustrating how concepts really work, the book presents a cost-effective, easy-to-master approach to analytical modeling of stormwater management systems.

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.

Former industrial and urban land is increasingly being recycled, a practice which follows current political policy and is appropriate in the more heavily populated areas of Europe. The contamination which soils and water below such land may have suffered due to past industrial activities could pose future risks to new occupiers, or to the environment as a whole, and therefore it is important that an assessment of the risk is undertaken before such land is re-used. This volume has been written specifically to assist developers, consultants and planners who are involved in the reclamation of contaminated land in ensuring that such recycling does not expose the public or the wider environment to unacceptable risks. It provides a clear rationale for why such risk assessments are needed, outlines the current legislation regulating such activities, and indicates where the responsibilities lie for control of this development. Inevitably, the assessment approach of this book draws mainly on UK experiences and regulations but the methodology and basic principles provided are universal, and would be applicable when the safe recycling of contaminated land becomes a more important issue of development in other countries. The risk assessment approach advocated in the book will be valuable to many developers of contaminated land, since it is affordable and logical, and adequately diagnostic to identify sites where re-use will not be hazardous. The book describes a comprehensive range of risks which have been given due consideration as potential problems when former industrial land is reused, whilst also dispelling many of the vague and often unjustified concerns over land contamination.

The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal mixing and salt intrusion. The shape of an alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal excursion, phase lag, tidal damping, tidal amplification), wave celerity, lateral and vertical mixing and salt intrusion.
The book presents a review of the state of the art, a comprehensive theoretical background and ample case illustrations from all over the world. It provides tools with which human interference in estuary dynamics can be described and predicted, resulting from, for instance: upstream fresh water abstraction, dredging, climate change or sea-level rise. In describing the interactions between tide, topography, water quality and river discharge, it provides useful information for hydraulic engineers, morphologists, ecologists and people concerned with water quality in alluvial estuaries.
Although the book can be used as a text book, it is mainly a monograph aimed at graduate students and researchers.
* Provides new integrated theory for tidal hydraulics, tidal mixing and salt intrusion in alluvial estuaries
* Presents a consistent set of analytical equations to compute tidal movement, tidal mixing and salt intrusion, derived from the fundamental laws of conservation of mass and momentum
* Serves as a practical guide with many illustrations of applications in real estuaries

Hydraulic fracturing, commonly referred to as "fracking," is a technique used by the oil and gas industry to mine hydrocarbons trapped deep beneath the Earth's surface. The principles underlying the technology are not new. Fracking was first applied at the commercial level in the United States as early as 1947, and over the decades it has been applied in various countries including Canada, the UK, and Russia. The author worked with engineering teams as early as the mid-1970s in evaluating ways to improve oil recovery from this practice. By and large fracking was not an economically competitive process and had limited applications until the early 2000s. Several factors altered the importance of this technology, among them being significant technological innovations in drilling practices with impressive high tech tools for exploration, well construction and integrity, and recovery along with discoveries of massive natural gas reserves in the United States and other parts of the world. These factors have catapulted the application of the technology to what is best described as the gold rush of the 21st century, with exploration and natural gas plays proceeding at a pace that seemingly is unrivaled by any historical industrial endeavor. But this level of activity has invoked widespread criticism from concerned citizens and environmental groups in almost every nation across the Globe. This outstanding new volume offers the industry a handbook of environmental management practices that can mitigate risks to the environment and, through best practices and current technologies, to conform to the current standards and regulations that are in place to provide the world with the energy it needs while avoiding environmental damage. For the new hire, veteran engineer, and student alike, this is a one-of-a-kind volume, a must-have for anyone working in hydraulic fracturing.

This book shares essential insights on evaporites and their effects on dams and reservoirs. The intensity of the solution and suffusion process in evaporites (gypsum and salt) is much greater than the solution of carbonates, and evaporites are particularly vulnerable at dam and reservoir sites. Moreover, the presence of evaporites in the vicinity of dams or reservoirs often leads to serious problems: numerous dams in countries around the world (e.g. China, Germany, Iran, Iraq, Peru, Russia, Spain, the Unites States, and Venezuela) have been affected by evaporite dissolution problems. Several of these dams were seriously endangered or ultimately abandoned, even though the best available engineering prevention and remediation practices were applied. Conventional geotechnical methods based on treating the underground (e.g. grout curtains) or surface (e.g. protective blankets) were not successful. This book presents and analyzes revealing case studies in this regard. To improve geotechnical remediation in connection with preventing seepage from reservoirs situated in evaporites, particularly in gypsum, it puts forward a new chemical solution that, after painstaking laboratory testing, was successfully applied in the field.

This research is dedicated to studying longterm estuarine morphodynamic behavior under combined river and tidal forcing. Analysis of river tides in the Yangtze River estuary (YRE) in China, schematized morphodynamic modeling in 1D and 2D mode and morphodynamic modeling of the YRE based on a process-based numerical model (Delft3D) are conducted. Morphodynamic sensitivities to river discharge magnitude and time variations, tidal strength and tidal constituents are then systematically explored. Analysis of river tides in the YRE reveals strong river-tide interactions and non-linear modulation of tides by river discharge. River discharge alters tidal asymmetries and resultant tidal residual sediment transport. Analysis of morphodynamic modeling results exposes significant mechanisms inducing tidal residual sediment transport and controlling long-term morphodynamic development. Morphodynamic equilibria in 1D and 2D simulations can be defined by vanishing gradients of tidal residual sediment transports and meeting empirical morphodynamic relationships. This research indicates the value of numerical modeling in examining long-term morphodynamic development in millennia time scale. Understanding of the controls on morphodynamic behavior in estuaries under river and tidal forcing is to the benefit of managing estuaries' functions in a long-term point of view.
