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.

Dams have emerged as one of the most important tools for the management of rivers. Over 45,000 large dams around the world have played an important role in helping communities and economies harness water resources for food production, energy generation, flood control and domestic use. The benefits derived from large dams have made a significant contributions to human development. Floods have taken a large toll of human lives over the years and also caused large economic losses. World Bank is pushing construction of large dams. Along with dams, the river interlinking project is also under consideration in India. The more recent focus has been on the strategic development of sustainable irrigation practices within an integrated Catchment Management context. World Commission on Dams (WCD) has suggested some recommendations and strategic priorities for the construction of dams. WCD report has proved to be important in reducing environmental and social challenges. This book aims at exploring the significance of rivers and dams from economic, ecological, social and cultural angles. The book tries to present general patterns and trends in the management of rivers as well as planning and operation for large dams.

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
