 The water-waves theory is considered a fascinating and interesting topic, including a really broad range of various natural phenomena, and covering the most important general aspects of the motion of waves, including the waves' behavior prediction in the presence of various obstacles.
However, even the simple problems sometimes appear to be quite difficult to be tacked mathematically unless you make some simplified assumption. The present interesting title has been mainly dedicated to the advanced mathematical work directly relating to the scattering of the water waves.
The main emphasis as been laid by the author on the computational and mathematical techniques that are commonly necessary in order to perform the mathematical study of these problems. The main content of this title is made up of nine chapters with the first chapter being pure introductory while the second one addresses the wave scattering that involves the rigid plates.
The following two parts cover the scattering by a rectangular trench utilizing the Galerkin technique, and scattering by a dock utilizing the Carleman equation. The fifth chapter touches several problems including the upper surface discontinuities. Remaining chapters of the work deal with the energy identities, scattering of the two-layer fluids and various wave scattering problems...
 And here is the excellent handbook specifically designed and released for the environmental managers and policy-makers who are working for the water authorities and will also be useful for the engineering companies directly involved in various water quality programs, especially ones in the developing countries. The book will also be found suitable when used as a textbook or main/supplementary training material for the associated WQM training courses.
The recent years showed the constantly increasing awareness of the water pollution and serious concern about it all around the planet. Numerous completely new approached have been introduced and developed in order to achieve the sustainable and reasonable exploitation of the various water resources. It goes without any saying that the duly worked out policy framework is a critically important element in water resource management. The opening chapter of this volume is intended to propose some of the general principles for the entire process of policy making and of the structure or relevant policy documentation.
The text is supplemented with several real life examples of the policy elements supporting the sustainable management of the resources. The other chapters concentrate on the strategy formulation and outline the major guiding principles for the control of the water pollution.
 This book by Edward Bryant describes very comprehensively the nature and process of tsunamis; the author outlined field evidence for detecting past tsunami events, and describes ones linked to the earthquakes, submarine landslides, volcanoes and impacts of meteorites. It is aimed to be the information source for researchers and students, though will be very useful for the general public interested in this sort of natural hazard.
The main focus of this publication is formation of landscape features by tsunami; it is a really needed and up-to-date work with worldwide coverage. The lists of relevant figures, tables and symbols are included in the content of the book, together with acronyms and abbreviations used. The book starts with the introduction, supplemented with real-life stories and followed with the causes, characteristics and wave theory of tsunamis; the second chapters is dedicated to the landscapes formed by the tsunamis, including the depositional and erosional signatures.
This chapter is followed with one addressing the evolution of the coastal landscape. The remaining chapters deal with the volcanic eruptions, comets and asteroids, great landslides, risk and avoidance. The stories forming the foundation of the description of tsunamis and associated discussions are based on the materials of the live examples.
 As it is clear from the title, the book is dedicated to the ecology of the sea shores. It has been specifically designed to be used by the students at graduate students as well as the students at upper-graduate level plus the professionals who are engaged in the management and research related to the coastal zones.
The content of the book has been arranged in seven parts; the first part provides readers with some introduction to the ecology of the sea shores, and it also sets the scene for the remaining chapters of the publication. The second chapter of the book is dealing with the zonation patterns and the basic causes, together with the key components of the marine fauna, special habitats and other relevant matters.
The following chapter is covering the physicochemical environment and general biota. Then, there are two large sections of the volume dealing with the microbial ecology, detritus and nutrient cycles in the eco-systems in question. The remaining parts of the title address the existing ecological niches , maintenance/establishment of various zonation patterns, predation, disturbance and other factors determining the distribution and diversity, plus production of consumers, energy flow and flood webs, examples of the models of ecosystems, new network analysis techniques, comparison of the ecosystems etc.
 More than a century ago, B. Helland-Nanses and I. Snadstrom and proposed a method of computing the ocean currents on the basis of the water density distribution. Later, this method became known as the dynamic method for computing elements of the ocean currents, or hydrological data analysis method.
This is the indirect method and fully bases on the theoretical assumption that the coriolis force and horizontal pressure gradient are in equilibrium in the steady state below the mixed layer of the ocean surface. The velocities of the current are calculated by means of the dynamic method. The present volume is the author's attempt to properly justify the method referred to above, theoretically and also to shed some light on the nature of currents calculated/computed using this method.
It also examines the importance of the depth of reference surface and the accuracy of the computations. In addition, the book contains the descriptions of the structure of the gradient component of a wind-driven current velocity.
However, the author of the title does not attempt to provide a thorough treatise on the method in question, but is rather trying to analyze some of the important aspects of the theoretical principles of the dynamic method together with the possible practical applications, using the ocean currents theory.
 According to the author, his original intention was that this volume would serve several different purposes, including giving readers an overall picture of the several aspects of charting and surveying and, at the same time, going a bit deeper into those of the subjects which commonly seem to require some additional attention, or are in need of a more modern approach.
Also, where deemed desirable, several completely new subjects have been introduced. In the meantime, it was considered a necessity not to overlook simpler methods and less complicated equipment, as not every survey ship possesses the modern equipment for the electronic data processing on board with all required instruments recording on-line. When writing this volume, the author hoped that it would assist hydrographic as well as all other marine surveyors facing with the difficulties when establishing an efficient hydrographic office and performing effective surveys for their country; who are often required to provide guidance to younger officers, not having readily available sophisticated data collection and further processing devices.
As declared by W. Langeraar, the author, a serious need exists for a title not only discussing the latest equipment and all associated methodologies, but which is also covering less complicated instruments and methods...
 This volume has been released with the intention of it's editor, J. Nihoul, who prepared it trying to compile in a single volume, all proceedings of the XIX International Colloquium on the problems of ocean hydrodynamics. The program of the subject conference was focusing on the relationships existing there between large- and small-scale features, together with the associated processes and transports.
The volume presents the valuable articles covering the different methods of parameterization of small-scale turbulent mixing as applied to the numerical ocean models, the presentation of subject papers has been specifically encouraged by the editor, and the application of the subject approach has finally resulted in significant portion of the articles presented during the Colloquium, dealing with the current problems of parameterization. Note that some of the presented docs demonstrated the direct results obtained during the modeling.
The volume is well reflecting the above stated proportion and emphasizes the whole importance of the researches oh small-scale turbulence for the practical applications, such as the forecasting and ocean modeling. The book will be equally useful, practical and informative for persons willing to be in the loop of any latest happenings in the subject field.
 The correct understanding of the basic processes occurring at the sea-level, is really a key to the effective planning of the coastal defense arrangements. Such process would commonly include storm surges and ocean tides, rises plus all other processes that are usually caused by the climate changes.
The content of the present work mainly bases on the valuable technical materials contained there in the recognized scientific publications and researches dedicated to this subject, that were significantly expanded and incorporating all important technological advances in the relevant areas, for example the tsunami science, satellite altimetry, and analysis of the extreme sea-levels.
The duet of authors of the work, Philip Woodworth and David Pugh, have made an attempt to compile a discussion of how the measurement and survey techniques complement others in the course of providing the reliable forecasts of the forthcoming changes. This book may be treated as one of maybe the most exciting and authoritative volumes considered quite essential for the students, scientists and researchers in various fields; these fields would include marine engineering and marine biology/geology, climatology plus oceanography, as well as any other relevant disciplines. This interesting volume will also be of great use to persons who are involved in making key decisions plus coastal engineers.
