Available in PDF, EPUB and Kindle. Book excerpt: Water wave kinematics is a central field of study in ocean and coastal engineering. The wave forces on structures as well as sand erosion both on coastlines and in the ocean are to a large extent governed by the local distribution of velocities and accelerations of the water particles. Our knowledge of waves has generally been derived from measurements of the water surface elevations. The reason for this is that the surface elevations have been of primary interest and fairly cheap and reliable instruments have been developed for such measurements. The water wave kinematics has then been derived from the surface elevation information by various theories. However. the different theories for the calculation of water particle velocities and acceleration have turned out to give significant differences in the calculated responses of structures. In recent years new measurement techniques have made it possible to make accurate velocity measurements. Hence. the editors deemed it to be useful to bring together a group of experts working actively as researchers in the field of water wave kinematics. These experts included theoreticians as well as experimentalists on wave kinematics. It was also deemed useful to include experts on the response of structures to have their views from a structural engineering point of view on what information is really needed on water wave kinematics.

Available in PDF, EPUB and Kindle. Book excerpt: Four years have elapsed since the preparation of the original Russian version of this book. This is a long time when dealing with such actively expanding fields of oceanography as research into small-scale structures and the investigation of hydro physical processes. Over this period new quick-response devices have been developed and successfully used for measurements taken in various ocean areas. Improvements in high-frequency meters used to measure hydrophysical parameters has enabled workers to obtain more accurate absolute values of the fluctuations measured by such devices. In view of this scientific progress, some of the ideas presented in this book now require additional explanation. Great care should be used in dealing with the absolute fluctuation values of hydro physical fields, since the methods used for the determination of the accuracy of the high-frequency measuring devices have been imperfect in the past. Never theless, it would appear that the results of the investigations summarized in this book have not lost their importance, and that the established laws governing small-scale pro cesses in the ocean are of a sufficiently universal nature and, as such, have not been shattered with the qualitative and quantitative advances in devices used for measurements taken in oceans. The authors feel that their work is of interest to English-speaking readers. The appearance of the English translation of the book is, to a very large extent, due to the tremendous amount of editing work brilliantly done by Prof. H. Tennekes.

This book was released on 2004-08-20 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an introduction to the physical processes of cohesive sediment in the marine environment. It focuses on highly dynamic systems, such as estuaries and coastal seas. Processes on the continental shelf are also discussed and attention is given to the effects of chemistry, biology and gas.The process descriptions are based on hydrodynamic and soil mechanic principles, which integrate at the soil-water interface. This approach is substantiated through a classification scheme of sediment occurrences in which distinction is made between cohesive and granular material. Emphasis is also placed on the important interactions between turbulent flow and cohesive sediment suspensions, and on the impact of flow-induced forces on the stability of the seabed. An overview of literature on cohesive sediment dynamics is presented and a number of new developments are highlighted, in particular in relation to floc formation, settling and sedimentation, consolidation, bed failure and liquefaction and erosion of the bed. Moreover, it presents a summary on methods and techniques to measure the various sediment properties necessary to quantify the various parameters in the physical-mathematical model descriptions. A number of examples and case studies have been included.

Download or read book Stochastic Hydraulics 2000 written by Z.Y. Wang and published by CRC Press. This book was released on 2020-12-17 with total page 917 pages. Available in PDF, EPUB and Kindle. Book excerpt: The applications of stochastic methods in design by reliability include the better utilisation of hydrological information. With statistical methods one can evaluate the safety component of hydraulic systems. Based on these, extra safety features can be added to ensure the reliable performance of an hydraulic system. One such example is the design of a dam, which features a number of random variables, each with a very distinct and quite different probability function. This book reports on developments in stochastic hydraulics across a wide range of applications, including river hydraulics, sediment transportation, waves and coastal processes, hydrology, hydraulic works and structure, and environmental hydraulics.

Download or read book A Study of Turbulence and Fine Scale Temperature Variability of the Ocean Thermal Boundary Layer Under Breaking Surface Waves written by Johannes Richard Gemmrich and published by . This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Although turbulence near the ocean surface is of great significance to the air-sea exchange of heat, gas and momentum it is a poorly understood phenomenon especially at high wind speeds when vertical transfer processes tend to be greatest. This work evaluates ocean surface turbulence at high sea states by exploiting heat as a naturally occurring passive tracer. To this end, a freely drifting instrument with a mechanically driven temperature profiler, fixed depth thermistors and conductivity cells was used to monitor the fine scale temperature structure and breaking wave activity. These open ocean measurements form the basis for a comprehensive account of the near surface turbulence field. Temperature profiles reveal a rich fine structure which, when combined with independent air-sea heat flux measurements reveal the presence of a surface layer of wave enhanced turbulence, modulated by subsurface advection associated with Langmuir circulation. The concept of wave enhanced turbulence, previously based on observations in fetch limited environments, is here extended to open ocean storm conditions. Generation of turbulence depends on the scale and frequency of breaking events. Our observations, which span a wide range of conditions from a coastal strait to the open ocean, show that wind speed or wave age are inadequate predictors of the occurrence frequency of wave breaking, motivating a scaling based on energy input. The decay of turbulence following wave breaking proceeds more rapidly than for isotropic turbulence, permitting generation of a thermal boundary layer a few centimetres thick, which accounts for brief temperature fluctuations observed beneath breaking waves. Advection due to Langmuir circulation also leaves its signature on the near surface temperature field. Both advection and enhanced diffusion are reconciled in a two-dimensional model of the upper ocean boundary layer, providing a framework for studying Langmuir circulation and upper ocean turbulence in terms of the measured temperature structure. The depth integrated dissipation derived from a model analysis of the data closely matches the energy input into the wave field, identifying breaking waves as the major source of turbulent kinetic energy.
