Book Description
This book treats the subject of sediment transport in the marine environment, covering transport of non-cohesive sediment by waves and current in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required. It is intended for M.Sc. and Ph.D. students. The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. It does not present a large number of different formulae for the sediment transport rates under various conditions. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described; in the second, sediment transport and morphological development are treated. The hydrodynamic part contains a review of elementary theory for water waves, chapters on the turbulent wave boundary layer and the turbulent interaction between waves and currents, and finally, surf zone hydrodynamics and wave driven currents. The part on sediment transport introduces the basic concepts (critical bed shear stress, bed load, suspended load and sheet layer, near-bed concentration, effect of sloping bed); it treats suspended sediment in waves and current and in the surf zone, and current and wave-generated bed forms. Finally, the modelling of cross-shore and long-shore sediment transport is described together with the development, of coastal profiles and coastlines.

Book Description
This book is intended as a useful handbook for professionals and researchers in the areas of Physical Oceanography, Marine Geology, Coastal Geomorphology and Coastal Engineering and as a text for graduate students in these fields. With its emphasis on boundary layer flow and basic sediment transport modelling, it is meant to help fill the gap between general hydrodynamic texts and descriptive texts on marine and coastal sedimentary processes. The book commences with a review of coastal bottom boundary layer flows including the boundary layer interaction between waves and steady currents. The concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment diffusivity. The quasi-steady processes of sediment transport over flat beds are discussed. Small scale coastal bedforms and the corresponding hydraulic roughness are described. The motion of suspended sand particles is studied in detail with emphasis on the possible suspension maintaining mechanisms in coastal flows. Sediment pickup functions are provided for unsteady flows. A new combined convection-diffusion model is provided for suspended sediment distributions. Different methods of sediment transport model building are presented together with some classical models.

Book Description
The benthic boundary layer is the zone of water and sediment immediately adjacent to the bottom of a sea, lake, or river. This zone is of considerable interest to biologists, geochemists, sedimentologists, and engineers because of very strong gradients of energy, dissolved and solid chemical components, suspended matter, and the number of organisms that live there. It is, for example, the sink for anthropogenic substances and the home of microscopic plant life that provides the nutrients that determine fish populations--and ultimately the size of the fisheries. This book of original chapters edited by Professors Boudreau and Jorgensen, both leading researchers in the field, will meet the need for an up-to-date, definitive text/reference on measurements, techniques, and models for transport and biochemical processes in the benthic boundary layer. Each chapter provides a comprehensive review of a selected field, with illustrated examples from the authors' own work. The book will appeal to professionals and researchers in marine biology, marine chemistry, marine engineering, and sedimentology.

Book Description
This book treats the subject of local scour around different kinds of marine structures, exposed to waves and/or currents. The first, major part of the book is devoted to marine pipelines, describing in detail all kinds of scour scenarios, and also making recommendations for scour protection. Other kinds of structures considered are single piles (slender or large), groups of piles, complex subsea structures, breakwaters, and seawalls. The scour due to ship propellers is also described. The book deals mainly with the scour in noncohesive sediment but, whenever possible, available literature on the scour in finer sediment has been incorporated. In addition, a chapter on the impact of wave-induced liquefaction is included.The authors' aim is to describe in detail the hydrodynamic processes causing the erosion. With a hydrodynamic understanding, it is easier for the consulting engineer to predict scour in those many cases where physical model tests are not available.

Book Description
The practical engineer looking for an urgent solution to a sediment-related project often finds that the results of the relevant academic research are published in unfamiliar language in publications that are not easily available. Dynamics of marine sands bridges the gap between academic research and practical applications by summarising the research results in a unified form, backed up with worked examples and case studies. This comprehensive new book presents methods for calculating the various hydrodynamic and sediment dynamic quantities necessary for marine sediment transport applications, and recommends the most appropriate methods to use for engineering projects.
