The theory of waves is generalized on cases of strongly nonlinear waves, multivalued waves, and particle–waves. The appearance of these waves in various continuous media and physical fields is explained by resonances and nonlinearity effects. Extreme waves emerging in different artificial and natural systems from atom scale to the Universe are explored. Vast amounts of experimental data and comparisons of them with the results of the developed theory are presented. The book was written for graduate students as well as for researchers and engineers in the fields of geophysics, nonlinear wave studies, cosmology, physical oceanography, and ocean and coastal engineering. It is designed as a professional reference for those working in the wave analysis and modeling fields.

This book examines the reasons behind the resonant amplification of seismic and ocean waves that have the capacity to destroy cities and ocean-going vessels. Using Charles Darwin’s important geophysical research as a starting point, it provides insights into the interaction between earthquakes with volcanoes, seaquake, and tsunami formation. In particular, the author details the observations that Darwin made on a powerful earthquake that occurred in Chile in 1835, noting how the famous naturalist and geologist used the concept of earthquake-induced vertical shock to explain the event's devastating impact. The book then goes on to show how Darwin's concept relates to the catastrophic results of the shallow quakes that recently destroyed Port-au-Prince (Haiti, 2010) and severely damaged Christchurch (New Zealand, 2011). In addition, the author asks whether Darwin's ideas are endorsed by the discoveries of modern science and whether the results of destructive earthquakes can be modeled using strongly nonlinear wave equations. Coverage also proposes that similar equations can be used to simulate the dynamics of many objects on the surface of the Earth, and to model the origin of the Universe, dark matter, and dark energy as strongly nonlinear wave phenomena. The book will appeal to students as well as researchers and engineers in geophysics, seismology, nonlinear wave studies, cosmology, physical oceanography, and ocean and coastal engineering. It will also be of use to those who are interested in the phenomena of natural catastrophes as well as those who want to learn more about the life and work of Charles Darwin.

The theory of waves is generalized on cases when waves change medium in which they appear and propagate. A reaction of structural elements and space objects to the dynamic actions of the different nature, durations, and intensities is studied. It considers the effects of transitions in the state and phase equations of media on the formation and propagation of extreme waves as a result of power, thermal, or laser pulsed action. The influence of cavitation and cool boiling of liquids, geometric and physical nonlinearity of walls on containers’ strength, and the formation of extreme waves is studied. The theory can be also used to optimize impulse technology, in particular, in the optimization of explosive processing of sheet metal by explosion in a liquid. This book was written for researchers and engineers, as well as graduate students in the fields of thermal fluids, aerospace, nuclear engineering, and nonlinear waves.
Concluding remarks Paleotsunami research has grown rapidly since its
foundations in the late 1980s, and the appreciation of sediment records resulting
from hazardous extreme-wave events for coastal risk management has increased
Author: Max Engel
Geological Records of Tsunamis and Other Extreme Waves provides a systematic compendium with concise chapters on the concept and history of paleotsunami research, sediment types and sediment sources, field methods, sedimentary and geomorphological characteristics, as well as dating and modeling approaches. By contrasting tsunami deposits with those of competing mechanisms in the coastal zone such as storm waves and surges, and by embedding this field of research into the wider context of tsunami science, the book is also relevant to readers interested in paleotempestology, coastal sedimentary environments, or sea-level changes, and coastal hazard management. The effectiveness of paleotsunami records in coastal hazard-mitigation strategies strongly depends on the appropriate selection of research approaches and methods that are tailored to the site-specific environment and age of the deposits. In addition to summarizing the state-of-the-art in tsunami sedimentology, Geological Records of Tsunamis and Other Extreme Waves guides researchers through establishing an appropriate research design and how to develop reliable records of prehistoric events using field-based and laboratory methods, as well as modeling techniques. Features a comprehensive overview of the state of the art in tsunami sedimentology and paleotsunami research Offers advice on the most appropriate mapping, sampling, and analytical approaches for a wide variety of coastal settings and sedimentary environments Provides methodological details for field sampling and the most important proxy analyses

Previous studies have indicated that certain extremely large waves, measured during Hurricane Camille, might be characterized as non-Gaussian. Waves of similar time-domain description had previously been found to cause ship damages during winter storms. Interviews with ship masters and officers furnished additional important characterizations of these waves, as well as indications of the synoptic weather conditions which were involved. A survey of heavy-weather damage information from Coast Guard records was conducted to evaluate general trends of heavyweather damage to ships. A preponderance of damage is attributed to local wave loadings. Selected cases of ship damage and severe hull girder stressing were examined in relation to the types of extreme waves reported to have been encountered, or believed to have been encountered, based in part upon prevailing synoptic weather conditions. A tentative characterization of large non-Gaussian waves is provided. Recent developments in nonlinear wave mechanics are reviewed to help explain the origin and propagation of these waves. Current studies of the synoptic development of winter storms are examined to identify wind field characteristics which appear to be related to the development of 'rogue' waves.

This new book focuses on recent and significant research on non-linear, or chaotic behaviour which in real world systems has been reported in electronic circuits and communications systems, chemical reactions, biological behaviour. The applications include solitons, integrable systems, cellular automata, pattern formation, qualitative structure and bifurcation theory, onset of chaos and turbulence, analytic dynamics, and transport phenomena.

"The objective of this work is to apply the free-surface random vortex method (FSRVM) to study the interactions of surface waves and bodies. A FSRVM-based "numerical wavetank" is used to calculate forces on submerged bodies. To study the response of a freely-floating body in waves, the dynamic coupling between a rigid body and the fluid is formulated. To further improve the efficiency of the FSRVM, merger and decay of blobs are introduced to alleviate computational efforts of vortex interactions" [Source : extrait de l'abstract, p. 1].
