Available in PDF, EPUB and Kindle. Book excerpt: The numerical method developed by Wallace and Wonderley for calculating the deformation of a solitary wave moving onto a steep seawall was extended to beach slopes as small as 9 deg. The calculated results show that the existing dipole flow model does not adequately represent the wave deformation for beach slopes this small. Fundamental changes in the mathematical model appear to be required for the same accuracy with which the dipole model represents undeformed solitary waves. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Construction of the solitary wave from the field of a single dipole (doublet) within a closed domain is reviewed. Computer results are presented for wave profiles - both of solitary waves propagating in fluid of uniform depth an d of waves in various states of deformation on a 45-degree slope. Determination of unique correspondence between solitary waves in the state of steady propagation and wave profiles in a state of deformation on the slope has not been completed; but the range of possible deformed profiles on the slope that are accessible to the stable solitary waves is illustrated and discussed. Solitary wave profiles for fluid of uniform depth in the range of amplitude-to-depth ratios from 0.20 to 0.88 are also included for easy comparison with experiment. (Author).

This book was released on 1997-05-05 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since September 1992, there has been an unprecedented number of major tsunami events. Chronologically, the ten sites were: Nicaragua, in September 1992; Flores, Indonesia, in December 1992; Okushiri, Japan, in July 1993; East Java, Indonesia, in June 1994; Shikotan, Russia, in October 1994; Mindoro, Philippines, in November 1994; Skagway, Alaska, in November 1994; East Timor, Indonesia, in May 1995; Irian Jaya, Indonesia, in February 1996; Chimbote, Peru, in February 1996. These tsunamis caused substantial damage and many casualties. Now is the time to review this extraordinary phenomenon so as to prepare for forthcoming tsunami events.The purpose of this book is to review and update our knowledge of long-wave runups and our recent experience in field surveys of tsunami runups. Comparisons of numerical, analytical, and physical prediction models are made using existing laboratory and field data. Also presented are state-of-the-art tsunami prediction models and detailed discussions on tsunami runup phenomena.

Download or read book Simulation of Water Waves by Boussinesq Models written by Ge Wei and published by . This book was released on 1997 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new set of time-dependent Boussinesq equations is derived to simulate nonlinear long wave propagation in coastal regions. Following the approaches by Nwogu and later by Chen and Liu, the velocity (or velocity potential) at a certain water depth corresponding to the optimum linear dispersion property is used as a dependent variable. Therefore, the resulting equations are valid in intermediate water depth as well as for highly nonlinear waves. Coefficients for second order bound waves and the third order Schrodinger equation are derived and compared with exact solutions. A numerical model using a combination of second and fourth order schemes to discretize equation terms is developed for obtaining solutions to the equations. A fourth order predictor-corrector scheme is employed for time stepping and the first order derivative terms are finite differenced to fourth order accuracy, making the truncation errors smaller than the dispersive terms in the equations. Linear stability analysis is performed to determine the corresponding numerical stability range for the model. To avoid the problem of wave reflection from the conventional incident boundary condition, internal wave generation by source function is employed for the present model. Numerical filtering is applied at specified time steps in the model to eliminate short waves (about 2 to 5 times of the grid size) which are generated by the nonlinear interaction of long waves. To simulate the wave breaking process, additional terms for artificial eddy viscosity are included in the model equations to dissipate wave energy. The dissipation terms are activated when the horizontal gradient of the horizontal velocity exceeds the specified breaking criteria. Some of the existing models for simulating the process of wave runup are reviewed and we attempt to incorporate the present model to simulate the process by maintaining a thin layer of water over the physically dry grids.

Available in PDF, EPUB and Kindle. Book excerpt: It is proposed that solitary waves can be used as the initial wave shape to simulate the shoaling, breaking and run-up of large, long waves on a beach. Experiments were conducted with solitary waves to determine criteria for wave growth, celerity, breaking height and run-up on various beach slopes. In addition, limited investigations were made of reflected bores, effects of variations in the bottom profile, and the effect of multiple slopes, i.e., one slope followed by a second, higher slope, on the breaking and run-up of solitary waves. Further considerations are given to the method of characteristics as a means of analyzing shoaling waves. A qualitative analysis is presented of the effect of vertical acceleration terms on the solution. A comparison is made with other analytical solutions for shoaling waves. The experimental results are tabulated and plotted comparisons of the experimental results and the various analytical methods for shoaling waves are presented. (Author).

Download or read book River Flow 2016 written by George Constantinescu and published by CRC Press. This book was released on 2016-06-22 with total page 3703 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding and being able to predict fluvial processes is one of the biggest challenges for hydraulics and environmental engineers, hydrologists and other scientists interested in preserving and restoring the diverse functions of rivers. The interactions among flow, turbulence, vegetation, macroinvertebrates and other organisms, as well as the transport and retention of particulate matter, have important consequences on the ecological health of rivers. Managing rivers in an ecologically friendly way is a major component of sustainable engineering design, maintenance and restoration of ecological habitats. To address these challenges, a major focus of River Flow 2016 was to highlight the latest advances in experimental, computational and theoretical approaches that can be used to deepen our understanding and capacity to predict flow and the associated fluid-driven ecological processes, anthropogenic influences, sediment transport and morphodynamic processes. River Flow 2016 was organized under the auspices of the Committee for Fluvial Hydraulics of the International Association for Hydro-Environment Engineering and Research (IAHR). Since its first edition in 2002, the River Flow conference series has become the main international event focusing on river hydrodynamics, sediment transport, river engineering and restoration. Some of the highlights of the 8th International Conference on Fluvial Hydraulics were to focus on inter-disciplinary research involving, among others, ecological and biological aspects relevant to river flows and processes and to emphasize broader themes dealing with river sustainability. River Flow 2016 contains the contributions presented during the regular sessions covering the main conference themes and the special sessions focusing on specific hot topics of river flow research, and will be of interest to academics interested in hydraulics, hydrology and environmental engineering.
