As reservoir sedimentation has proven to be a serious problem in South Africa, research in this field has been ongoing for more than 70 years. This publication emanates from extensive research which has been undertaken over the past 30 years with the support of the South African Department of Water and Sanitation as well as the South African Water Research Commission. A great deal of information has fortunately also been obtained from China. Given the universal nature of hydraulic formulae it is not surprising, yet gratifying, that Chinese and South African data generally conform to the same mathematical relationships. This indicates that these relationships should be applicable in other countries as well. Much of the information contained here has been condensed from a more comprehensive publication. This ICOLD Bulletin follows on Bulletin 115 "Dealing with reservoir sedimentation", which gave guidelines for management of reservoirs to limit sedimentation. The guidelines on mathematical modelling of sediment transport dynamics in reservoirs in this document can be used during the planning and design of new dams, as well as for the management of existing dams. Comme la sedimentation dans les reservoirs s'est averee etre un probleme serieux en Afrique du Sud, la recherche dans ce domaine est en cours depuis plus de 70 ans. Cette publication emane de la recherche etendue qui a ete menee au cours des 30 dernieres annees avec l'appui du ministere sud-africain de l'eau et de l'assainissement, ainsi que de la commission sud-africaine de recherche sur l'eau. Un grand nombre d'informations ont egalement ete obtenues de la part de la Chine. Etant donne le caractere universel de formules hydrauliques, il n'est pas surprenant, mais tres gratifiant, que les donnees chinoises et sud-africaines se conforment generalement aux memes relations mathematiques. Ceci indique que ces relations devraient etre applicables dans d'autres pays egalement. Une grande partie de l'information contenue ici a ete condensee a partir d'une publication plus complete. Ce bulletin CIGB fait suite au bulletin 115 "Traite sur la sedimentation dans les reservoirs", qui a donne des directives pour la gestion des reservoirs en vue de limiter la sedimentation. Les directives sur la modelisation mathematique de la dynamique de transport des sediments dans les reservoirs de ce present document peuvent etre utilisees lors de la planification et la conception de nouveaux barrages et pour la gestion des barrages existants.

In the world of transportation, fatigue is a silent killer that can affect us all. Understanding fatigue, including how to manage it to minimize safety risk, is of great importance. However, while it is one thing to recognize that fatigue is a critical safety issue, it is quite another to set up a successful, scientifically informed fatigue risk management programme. This book is here to help. It has been carefully designed as a comprehensive reference point, bringing together international expertise from leaders in fatigue science, and showcasing valuable insights from transportation industry practitioners. The 40 authored chapters are divided into six sections, to better understand fatigue science, the consequences of fatigue in transportation, contributors to fatigue, managing fatigue and promoting alertness, real world case studies of fatigue management in practice, and future perspectives. While it is possible to read each chapter in isolation, most will be gained by reading the book as a whole. Each chapter starts with an abstract overview and concludes with summary bullet points, creating a handy "quick check" for key points. This accessible text is for those who are interested in supporting alert and safe transportation operations. It is suitable for professionals, transport managers, government advisors, policy makers, students, academics, and anyone who wants to learn more. All transport modes (road, rail, maritime and aviation) are considered. For anyone waking up to the complex challenge of fatigue management, this handbook is a must.

The past half century has seen an evolution in thinking from 'flood control' to 'flood risk management', recognizing that risk results from both hazard and vulnerability. Rather than rely only on engineering structures to reduce flood magnitude or extent, recent policies emphasize avoiding construction in flood-prone areas (or moving people from floodplains), reducing impacts on exposed populations through early warning systems, and insurance to aid in recovery. Implementing this new approach faces many challenges but also offers opportunities for synergies, as described in this book for a range of large floodplain rivers and smaller urban streams across North America and Europe. This book is unique in presenting the voices of those on the front lines of implementing a new paradigm in flood risk management, each river with a unique set of challenges and opportunities derived from its specific geography as well as differences in governance between the American and European contexts.

For decades, large dam projects have been undertaken by both nations and international agencies with the aim of doing good: preventing floods, bringing electricity to rural populations, producing revenues for poor countries, and more. But time after time, the social, economic, and environmental costs have outweighed the benefits of the dams, sometimes to a disastrous degree. In this volume, a diverse group of experts-involved for years with the Nam Theun 2 dam in Laos-issue an urgent call for critical reassessment of the approach to, and rationale for, these kinds of large infrastructure projects in developing countries. In the 2000s, as the World Bank was reeling from revelations of past hydropower failures, it nonetheless promoted the enormous Nam Theun 2 project. NT2, the Bank believed, offered a new, wiser model of dam development that would alleviate poverty, protect the environment, engage locally affected people in a transparent fashion, and stimulate political transformation. This was a tall order. For the first time, this book shows in detail why, despite assertions of success from the World Bank and other agencies involved in the project, the dam's true story has been one of substantial loss for affected villagers and the regional environment. Nam Theun 2 is an important case study that illustrates much broader problems of global development policy.

This proceedings book gathers contributions presented at the First International Conference on Embankment Dams (1st ICED, Beijing, 5-7 June 2020), which was the inaugural conference of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) Technical Committee TC210 on Embankment Dams. The contributions address five themes: (1) case histories on the failure of embankment dams and landslide dams; (2) dam failure process modelling; (3) soil mechanics for embankment dams; (4) dam risk assessment and management; and (5) monitoring, early warning and emergency response. These proceedings offer a unique resource that systematically presents recent dam breaching cases, their social impact, associated risk management strategies, and disposal methods for failed dams. It is an excellent reference guide for dam and levee engineers, flood safety officials, and emergency management agencies.

Grounded in the user-centered design movement, this book offers a broad consideration of how our civilization has evolved its technical infrastructure for human purpose to help us make sense of the contemporary world of information infrastructure and online existence. The author incorporates historical, cultural and aesthetic approaches to situating information and its underlying technologies across time in the collective, lived experiences of humanity. In today's digital information world, user experience is vital to the success of any product or service. Yet as the user population expands to include us all, designing for people who vary in skills, abilities, preferences and backgrounds is challenging. This book provides an integrated understanding of users, and the methods that have evolved to identify usability challenges, that can facilitate cohesive and earlier solutions. The book treats information creation and use as a core human behavior based on acts of representation and recording that humans have always practiced. It suggests that the traditional ways of studying information use, with their origins in the distinct layers of social science theories and models is limiting our understanding of what it means to be an information user and hampers our efforts at being truly user-centric in design. Instead, the book offers a way of integrating the knowledge base to support a richer view of use and users in design education and evaluation. Understanding Users is aimed at those studying or practicing user-centered design and anyone interested in learning how people might be better integrated in the design of new technologies to augment human capabilities and experiences.

This book expounds the hydraulics of fine sediment which is almost ubiquitously found in coastal and estuarine waters, and in rivers, lakes, and reservoirs. Although the basic subject may be categorized as applied marine physics in shallow waters, several physicochemical and biological effects on particulate transport have been addressed.In this second edition most of the chapters have been substantially updated, rewritten, and expanded. Overall, a significant change has also been made throughout by replacing sediment concentration, a unit dependent quantity at the heart of numerous descriptions, measurements, and calculations, with the nondimensional sediment volume fraction. It marks a divergence in the manner in which fine sediment transport data and calculations are conventionally presented.The book is mainly written for civil engineering seniors and graduate students, to offer a comprehensive foundation in hydraulics of fine sediment. The book is also a useful reference for researchers interested in the effects of physical chemistry and biology on fine sediment transport in water and to an extent on coastal and estuarine morphodynamics, sediment transport, port and harbor engineering, and applied shallow watwer marine physics. The book is also recommended reading for those interested in understanding particle transport in water.

Product design is becoming increasingly challenging as product complexity increases dramatically with the advent of autonomous control and the need to achieve zero emissions. Companies continue to have poor product launches with significant numbers of recall campaigns and high after-sales warranties. It is important that potential product failures are identified and fixed during the design of a product. Failure modes found late after the design has matured are normally easy to find with some being identified by the customer but are often difficult and expensive to fix since modifying one part will often have a knock-on effect on other parts causing other problems. Discovering failure modes early in the design process is often difficult requiring rigorous and comprehensive analysis but once found such failure modes are usually easy and cheap to fix. This book presents an approach to product design based on Failure Mode Avoidance that utilizes a series of strongly interrelated engineering tools and interpersonal skills that can be used to discover failure modes early in the design process. The tools can be used across engineering disciplines. Despite engineering being largely a team activity, it is often the case that little attention is paid to the team process after the team membership has been identified, with membership normally being based on technical expertise. In addition to technical expertise, an effective engineering team requires individual engineers to work together efficiently. Good leadership is also required with the leader able to both manage change and encourage individual team members to work to the best of their ability. The book interweaves technical skills, team skills, and team leadership in a way that reflects their real-life interrelationship. The book tells the fictional story of a small engineering team and its leader as they implement the skills introduced in the book and follows their experiences reflecting individual difficulties, enthusiasm, humor, and skepticism in applying the methodologies and tools for the first time. In addition, the story tells of team members' interactions with their management and peers within a company that, having been very successful, finds itself in financial difficulties. It promotes constructivist learning through the reader empathizing with the characters in the book. These characters ask questions that are typical of those that learners will ask about the subject matter. Learning reinforcement is also integrated into the storyline as a natural and unobtrusive feature. The book is intended to be read like a novel from cover to cover with a storyline that motivates the reader to read on. While including in-depth technical examples the book is not intended as a seminal text on Failure Mode Avoidance or team skills but is intended to give the reader an understanding such that they are motivated to learn more. Having read the book, it can be treated more typically as a textbook by returning to some of the technical detail or looking to further reading such as that identified in the book.

This edited volume compares seven countries in North America and Europe on the highly topical issue of oil and gas development that uses hydraulic fracturing or "fracking." The comparative analysis is based on the Advocacy Coalition Framework (ACF) and guided by two questions: First, in each country, what are current coalitions and the related policy output? Second, based on the current situation, what are the chances for future policy change? This book is the first to use a social science approach to analyze hydraulic fracturing debates and the first application of the ACF that is deliberately comparative. The contributions in this book advance our understanding about the formation of coalitions and development of public policy in the context of different forms of government and economically recoverable natural resources.
