This book treats the subject of sediment transport in the marine environment, covering transport of noncohesive sediment by waves and currents in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required.The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described. This 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 second part covers sediment transport and morphological development.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.

A new, very simple and dependable field sediment sampler has been developed. It is a multi-siphon device that samples suspended sand from seven elevations simultaneously. The 65 concentration profiles that have been obtained so far are presented, complete with hydrodynamics and bed sediment data. The profiles were measured under breaking and non-breaking waves in a wide rage of coastal environments all over Australia. These data together with a review of oscillatory boundary layer flow and the motion of suspended sand in an accelerated non-uniform flow lead to a range of new insights into the processes of sediment entrainment under waves.

This Proceedings contains 445 papers presented at the 30th International Conference on Coastal Engineering, which was held in San Diego, California, USA, 3-8 September 2006. The Proceedings is divided into five parts: Waves; Swash, Nearshore Currents, and Long Waves; Coastal Management, Risk, and Ecosystem Restoration; Sediment Transport and Morphology; and Coastal Structures. The individual papers cover a broad range of topics including theory, numerical and physical modeling, field measurements, case studies, design, and management. These papers provide engineers, scientists, and planners state-of-the-art information on coastal engineering and coastal processes.

Suspended sediment concentration was measured in 235 breaking waves on undeveloped beaches near Price Inlet, South Carolina, U.S.A., using portable in situ bulk water samplers. The purpose of the study was to determine what factors control the distribution of suspended sediment in the breaker zone. The final conclusion inferred from accumulated data is that sediment transport is highly dependent on breaker type. Net offshore movement and equilibrium profiles can be qualitatively explained on the basis of variations in wave form, beach slope and suspended sediment concentration. Longshore transport rates are dependent not only on wave height, but on breaker type, which can be quantified to reasonable certainty by the simple ratio, d sub b/H sub b, relative wave height.
