Coastal bottom boundary layers and sediment transport / Peter NIELSEN (1992)

Public ISBD Titre : Coastal bottom boundary layers and sediment transport Type de document : texte imprimé Auteurs : Peter NIELSEN, Auteur Editeur : Singapour : World Scientific Année de publication : 1992 Collection : Advanced Series on Ocean Engineering num. 4 Importance : 324 p. ISBN/ISSN/EAN : 978-981-02-0472-3 Langues : Anglais Mots-clés : transport de sédiments  vague Résumé : 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.

Mechanics of coastal sediment transport / Jorgen FREDSOE (1992)

Public ISBD Titre : Mechanics of coastal sediment transport Type de document : texte imprimé Auteurs : Jorgen FREDSOE, Auteur ; Rolf DEIGAARD, Auteur Editeur : Singapour : World Scientific Année de publication : 1992 Collection : Advanced Series on Ocean Engineering num. 3 Importance : 369 p. ISBN/ISSN/EAN : 978-981-02-0840-0 Langues : Anglais Mots-clés : côte  sédiment  transport de sédiments Résumé : 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.
