This text presents the state of the art in friction drag/resistance reduction technologies for BODIES and crafts operating in liquids at and beneath the free surface. It is useful for professionals with backgrounds in advanced fluid dynamics as well as by academics teaching introductory graduate courses in this area. Active control of resistance will include a discussion of friction reduction, for example through the injection of gas that can form air layers and polymers that initially reside adjacent to the hull, including the use of partial and super cavities. The book discusses passive resistance control achieved through changes in the overall hull shape and appendages, including the application of lifting bodies, bulbous bows, and stern flaps. It also addresses passive reduction of skin friction through the application of hull coatings and other elements of hull husbandry.

"Alvarez drives home the point that for buildings and communities located in hurricane-prone regions, it is not a question of whether the area will be impacted, but when it will be impacted. The book makes a strong case for taking responsibility to understand the vulnerabilities of buildings and structures to hurricane impacts." —Timothy Reinhold, PhD, from the Foreword Focusing on coastal regions affected by tropical cyclones, Hurricane Mitigation for the Built Environment highlights vulnerability, natural hazards, risk, damage, emergency management, and hazard mitigation as they relate to the threat and occurrence of hurricanes. The product of more than 25 years of the author’s experiences with post-event assessments and studies of hurricane damage, it looks particularly at common sequences of failures and oversights in planning for a hurricane that amplify the damage caused by storms. This book combines observations of actual damage to the built environment in coastal regions caused by hurricanes with applied research and testing. It uses case studies and imagery from recent storms to show some of the strengths and weaknesses of infrastructure, landscaping, and city planning. The case studies also illustrate, in great detail, what community planning efforts have worked and those that have failed. The book also goes beyond analyzing immediately visible structural damages following a hurricane. It addresses long-term issues such as beach erosion and struggling tourism economies. It also describes specific, realistic, and essential mitigation measures for reducing the damage potential of future hurricanes and urges developers, designers, and owners to incorporate new knowledge into the design of new buildings or into the retrofitting of existing buildings. By applying the information presented in this book, communities susceptible to recurring hurricanes can reduce storm damage as well as the potential for extended losses that frequently follow a hurricane.

This handbook examines the latest techniques and strategies that are used to unlock the risk transfer capacity of global financial and capital markets. Taking the financial crisis and global recession into account, it frames and contextualises non-traditional risk transfer tools created over the last 20 years. Featuring contributions from distinguished academics and professionals from around the world, this book covers in detail issues in securitization, financial risk management and innovation, structured finance and derivatives, life and non-life pure risk management, market and financial reinsurance, CAT risk management, crisis management, natural, environmental and man-made risks, terrorism risk, risk modelling, vulnerability and resilience. This handbook will be of interest to academics, researchers and practitioners in the field of risk transfer.

The world’s population is expected to increase to over 8 billion by 2020. About 60% of the total population of the world lives in coastal areas and 65% of the cities with a population of over 2.5 million are located in coastal areas. Written by an international panel of experts in the fields of engineering and risk management, The Handbook of Coastal Disasters Mitigation presents a coherent overview of 10 years of coastal disaster risk management and engineering, during which some of the most relevant events of recent time have taken place, including the Indian Ocean tsunami, hurricanes Katrina and Sandy in the United States or the 2011 Japanese tsunami. International case studies offer practical lessons on how disaster resilience can be improved in the future Contains tools and techniques for analyzing and managing the risk of coastal disasters Provides engineering measures for mitigating coastal vulnerability to tsunamis, tropical cyclones, and hurricanes Includes crucial tactics for rehabilitation and reconstruction of the infrastructure

This book covers specific aspects of submarine hydrodynamics in a very practical manner. The author reviews basic concepts of ship hydrodynamics and goes on to show how they are applied to submarines, including a look at the use of physical model experiments. The book is intended for professionals working in submarine hydrodynamics, as well as for advanced students in the field. This revised edition includes updated information on empirical methods for predicting the hydrodynamic manoeuvring coefficients, and for predicting the resistance of a submarine. It also includes new material on how to assess propulsors, and includes measures of wake distortion, which has a detrimental influence on propulsor performance. Additional information on safe manoeuvring envelopes is also provided. The wide range of references has been updated to include the latest material in the field.
