Book Description
This book places research into worldwide beach environments in its geomorphological context. Having introduced the systems approach to environmental modelling, and identified the groups of processes operating on beaches, the text is structured in five parts: the first three sections provide a sequential account of the effects of these processes on the beach system; part four focuses on theory relevant to landform stability, then reviews existing empirical, analytical and numerical models; and the final section introduces a computer model and shows its application to the process functions developed earlier.
Longshore Sand Transport Distribution Across the Surf Zone Due to Random Waves

Book Description
Water waves are one of the principal causes of shoreline changes. When waves break along the shore, they release their energy and momentum and give rise to a longshore current. The longshore current, along with the stirring action of the waves, is the primary mechanism for longshore sediment transport. The longshore sand transport rate is an essential factor determining erosion or accretion along a coast. If the longshore sand transport rate can be accurately estimated, a quantitative picture of shoreline evolution can be evaluated, including changes of the shoreline due to marine structures. In the present study, analytical and numerical models are developed based on a longshore current model for random waves and a sediment transport formulation by Thornton to predict the cross-shore sediment transport distribution and to compute the total volume of sand transport rate. The model is compared with the field data acquired from Leadbetter Beach, Santa Barbara, California.
Mechanics of Coastal Sediment Transport
Author: Jørgen FredsøePublisher: World Scientific Publishing Company
ISBN: 9814365688
Category : Technology & Engineering
Languages : en
Pages : 392
Book Description
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.

Book Description
Waves on Beaches and Resulting Sediment Transport documents the proceedings of an Advanced Seminar held in October, 1971, aiming to offer a coherent, interdisciplinary view of the state of physical research in coastal oceanography and the direction in which this subject is moving. The articles range from wave refraction to littoral erosion, and the authors from geologists to mathematicians. The book opens with a study on the characteristics of wave records in the coastal zone. This is followed by separate chapters on sediment transport in beaches; equations for water waves; small-amplitude normal oscillations of a liquid body; and wave behavior near caustics in models and in nature. Subsequent chapters deal with nonlinear wave interaction in a variety of physical phenomena including deep water waves; the study of longshore currents; sediment suspension by periodic waves; forms of sediment accumulation in the beach zone; run-up on beaches; and the wave breaking process in shallow water.
