The aim of the book is to give an up-to-date review on dam-break problems, along with the main theoretical background and the practical aspects involved in dam failures, design of flood defense structures, prevention measures and the environmental social, economic and forensic aspects related to the topic. Moreover, an exhaustive range of laboratory tests and modeling techniques is explored to deal effectively with shock waves and other disasters caused by dam failures. Disaster management refers to programs and strategies designed to prevent, mitigate, prepare for, respond to and recover from the effects of these phenomena.To manage and minimize these risks, it is necessary to identify hazards and vulnerability by means of a deep knowledge of the causes which drive to dam failures, and to understand the flow propagation process.Knowledge and advanced scientific tools play a role of paramount importance of coping with flooding and other dam-break problems along with capacity building in the context of political and administrative frameworks. All these aspects are featured in the book, which is a comprehensive treaty that covers the most theoretical and advanced aspects of structural and hydraulic engineering, together with the hazard assessment and mitigation measures and the social economic and forensic aspects related to subject.
This is the story of the authors uncle, David Maltby and the crew with whom he flew on the famous Dam Raid in 1943. Just five months later, on their return from an aborted mission to bomb the Dortmund Ems Canal, they all died when their aircraft went down in the North Sea. Only Davids body was recovered, washed ashore a day later, and identified by his 18 year old sister the authors mother. David was the pilot of the fifth Lancaster, J-Johnny to drop a bomb on the Mhne Dam and cause the final breach in the dam. He was then just 23 years of age, but already had 30 operations and a D.F.C. to his name.This book tells the story of the crew, what made them join the RAF when they new the risk was so high, how fate threw them together, what it was like for one crew to take part in the raid and what happened to them in the five months between Operation Chastise and their deaths. It goes beyond the raid to look at what happened afterwards and how the families left behind were affected. Their sons, brothers and fathers might have become famous but they had to cope with life and loss in the same way as did thousands of other British families.
More than 800,000 dams and thousands of kilometers of dikes have been constructed around the world. These structures are often designed based on a statistical analysis of the discharge distribution in rivers. However, the history of construction of dams and dikes coexists with the history of failures. Hundreds of dam failure events were reported worldwide in the previous century, while every year dikes breach due to high flows in the rivers or for other reasons leading sometimes to catastrophic consequences. In this book a description is presented of a framework and techniques for modelling structure failure events as well as a proposal to several novel approaches for risk analysis and assessment by numerical, statistical and constrained based methods in particular to the problems of breach modelling and flood water mitigation.
Dams are constructed for economic development, and their construction involves large investments of money, and natural and human resources. Of the various types of dams constructed around the globe, earth dams are the most common type and constitute the vast majority of dams. When adam fails, it culminates in the sudden release of artificially stored water which, in turn, becomes a potential menace to virtually everything downstream. The dam failure may result in loss of life and property. In recent years, instances of dam failure in the world have been too many, and the resulting loss too high. As a result, dam safety pro grams have been developed in most countries of the world since the beginning of the nineteenth eighties. · Earth dams are more susceptible to failure than other types. The cause of failure is often either overtopping or piping. The modeling of dam breaching due to either or both of these causes is of fundamental importance to development of dam-safety programs. This book is, therefore, an attempt to present some aspects of earth-dam breach modeling technology. It is hoped that others will be stimulated to write more comprehensive texts on this subject of growing interest and importance. The book is divided into eight chapters. The first chapter is introductory and discusses some aspects of dams and dam failures in the world.
Early one May morning in 1874, in the hills above Williamsburg, Massachusetts, a reservoir dam suddenly burst, sending an avalanche of water down a narrow river valley lined with factories and farms. In just thirty minutes, the Mill River flood left 139 people dead and 740 homeless -- and a nation wondering how this terrible calamity had happened. In this compelling tale of a man-made disaster peopled with everyday heroes and arrogant scoundrels, Elizabeth Sharpe opens a rare window into industry and village life in nineteenth-century New England, a time when dam failures and other industrial accidents were widespread and laws favored factory owners rather than factory workers. In the Mill Valley, the townsfolk depended upon generally benevolent patriarchs who assured them that the dam was safe, when most people could see that it was not. The story of the Mill River flood is the story of those townsfolk: of George Cheney, the dam keeper whose repeated warnings about leaks in the dam had been ignored by the mill owners; of his wife, Elizabeth, who watched in disbelief as the dam burst open from the bottom; of Isabell Hayden, the mother who saw her young son swept away in the river's torrent; and of Fred Howard, a box maker who spent the days after the flood searching for bodies, burying friends, and waiting to see if the button factory he relied upon for his livelihood would be rebuilt. It is also the story of the well-meaning but overconfident businessmen who built the dam: of Onslow Spelman, the manufacturer who dismissed the dam keeper's flood warning, irrationally insisting that the dam could not break; of Lucius Fenn and Joel Bassett, the engineer and contractor whose roles in the construction of the dam would be questioned during the public inquest into the causes of the flood; of William Skinner, the factory owner who struggled to decide whether or not to rebuild his silk factory in the village that bore his name; and of many others. The flood highlighted class divisions between worker and owner, as well as the disorganized state of professional engineering, then still in its infancy. As the flood exposed the dangers of allowing mill owners -- who were not trained engineers -- to design their own dam, legislation to regulate the building of reservoir dams in Massachusetts was enacted for the first time. Engineers, politicians, and business owners battled over control of the reform measures to prevent similar tragedies, yet saw them continually repeated. In the Shadow of the Dam is the story of an event that reshaped a society. Told through the eyes of villagers like Collins Graves, lauded as a hero for his desperate ride through the valley to warn people of the impending flood, and industrialists like Joel Hayden Jr., entrusted with the responsibility of disaster relief despite his culpability in failing to maintain the leaking dam, In the Shadow of the Dam is a history of our uneasy relationship with industrial progress and a riveting narrative of a tragic disaster in small-town Massachusetts.
“This was Der Tag for 617 Squadron [...] from eight o'clock onwards the scenes outside the crew rooms were something to be remembered." “I watched each Lancaster become airborne from the window of my office but I did go outside to see all the boys roaring away into the fast approaching twilight, and that was a great thrill because they were flying at less than 150 feet from the ground. I just stood and gaped, hardly able to realise the significance of it all.” On the evening of Sunday 16 May, 1943, the sound of Lancaster bombers fills the night air around Lincolnshire as two waves of Allied aircraft start their engines and take off from RAF Scampton in the direction of the Ruhr Valley. The mission? Attack the German dams on the Eder, Möhne and Sorpe rivers using special “bouncing bombs”. This was Operation Chastise. In this remarkable work, No. 617 Squadron expert Dr Robert Owen takes a microscope to the raid, guiding readers through the events of 16 and 17 May 1943 in astounding chronological detail. Each action leading up to, throughout, and following the raid is signposted with a precise time stamp, affording readers an informative, gripping and easy-to-follow reading experience. Owen’s compilation of a wide range of first-hand accounts from those involved in the Dambusters Raid complements this minute-by-minute retelling perfectly, and adds to the readers’ understanding and appreciation of this astonishing military operation. With a foreword by World War II aviation expert and author James Holland, Breaking the German Dams is a hugely impressive feat of non-fiction writing about one of the most awe-inspiring operations in British military history. Readers will be left incredibly well-versed in — and moved by — the extraordinary story of Operation Chastise.
The General Assembly of the United Nations passed a resolution on December 11, 1987, designating the 1990s as the International Decade for Natural Disaster Reduction. This resolution has served as a catalyst in promotion of international cooperation in the field of natural disaster reduction; in initiation of wide-ranging research activities on natural and man-made disasters; in development of tech nologies for assessment, prediction, prevention, and mitigation through technical assistance, technology transfer, demonstration projects, and education and training; and in dissemination of information related to measures for assessment, prediction, prevention, and mitigation of natural disasters. Disasters are manifestations of environmental extremes. Depending upon the type of disasters, their occurrence may have short-term andlor long-term detri mental environmental consequences. Disasters cannot be prevented altogether, but their impact can be mitigated. This book is an attempt to provide a discussion of hydrological aspects of the various types of natural disasters. It is hoped that others will be stimulated to write more comprehensive texts on this subject of enormous importance.
