Book Description
A special publication of the International Association of Sedimentologists This comprehensive scientific book of more than 500 pages features chapters by various authors. Holocene Marine Sedimentation in the North Sea Basin address topics that include: ripple, megaripple and sandwave bedforms in South Wales; shoreline development in St Andrews Bay, Scotland; and the origin of ridges off the Zeeland coast. Highlighted research includes: measurements of suspended sediment concentrations made at stations on a sandy intertidal zone in South Wales, as well as another study of two cores from the southern side of the Norwegian Channel concerning geotechnical properties, texture, sedimentary structures and mineralogical composition.

Book Description
Barrier islands represent a complex coastal system that includes a number of different sedimentary depositional environments; nearshore zone, beach, dunes, washover fans, marshes, tidal flats, estuaries, lagoons, and tidal inlets. The morphodynamics of these fragile coastal systems provide a further complication to this coastal type. Although barrier islands comprise only 15% of the world's coastline, they have received a far greater proportion of attention from the scientific and engineering community, and more recently, from coastal managers and environmentalists. Modern barrier islands are arguably the most expensive and most vulnerable of all coastal environments. Pressure from developers for residential, industrial, and recreational development has caused most of our barriers to become significantly impacted by human activity, especially over the past few decades. These pres sures have led to extensive preservation of natural barriers through efforts from all levels of government and also by private organizations. Governments have also formed coastal management programs that help to control any future de velopment with the intent being to keep human activity compatible with barrier island morphodynamics. In order to devise appropriate coastal zone management programs, it is necessary to have a comprehensive understanding of the morpho dynamics of barrier island systems. This volume provides comprehensive details on barrier island morphology, sediment distribution, and the process-response mechanisms that cause changes to both. These are the important aspects of barrier systems that can provide important input into the development and implementation of coastal management programs.

Book Description
The tidal flat complex along the Atlantic coast of the southern Delmarva (Delaware-Maryland-Virginia) Peninsula lies at the distal end of littoral drifts along a gentle seacoast. The mean tide range is 1.0 to 1.5 m, and the gradual slope of the continental shelf reduces wave action to moderate or low levels. Such a low-energy siliciclastic tidal flat deposit has not been previously described, yet it is this low-energy kind of tidal flat that was probably common in ancient epeiric seas. The sediments of this tidal flat complex are primarily mud in contrast to the sand which characterizes the northern Delmarva sedimentary environments. Two fundamentally different processes (pelletization by organisms and tidal current transport with gravity settling) have been proposed to account for the accumulation of such fine-grained sediments. This report describes the textures, biota, and depositional structures of the Delmarva tidal flat deposits; emphasis is placed on the main sedimentary processes accounting for their accumulation.

Book Description
This volume, although not an integrated synthesis, treats most aspects of Holocene sedimenta tion and diagenesis in the Persian Gulf, grouping 22 contributions under a single cover and in one language. Because these sediments and diagenetic minerals are comparable to those existing in many ancient sedimentary basins, their appraisal should be of value to the enlarging group of workers who interpret ancient sedimentary rocks. The essential morphological, climatic and oceanographic factors determining Holocene sedimen tation and diagenesis in the Persian Gulf are summarized in the introductory article by PURSER and SEIBOLD. These environmental controls and the overall morphology of the Persian Gulf have much in common with Shark Bay, Western Australia, described by LOGAN et al. (1970). On the other hand, the Persian Gulf is markedly different from the better known Florida and Bahamian prov inces; the floor of the Persian Gulf is gently inclined from continental shoreline to bathymetric axis (80-100 m); the Bahamian province, on the other hand, is horizontal and extremely shallow (2-10 m), with very sharply defined shelf edges surrounded by deep oceanic waters. These contrast ing architectural styles are related to different tectonic frames.

Book Description
This IAS Special Publication contains 23 papers presented at the 3rd International Research Symposium on Modern and Ancient Clastic Tidal Deposits. This symposium series has an enviable international reputation for its quality, and so the contributions represent the latest developments in the field. The conference was preceded and followed by a number of field trips to some of the most prominent tidal flat and barrier island systems of continental Europe, and these have been written up as overview papers that summarize the current state of knowledge about these various tidal regions. The latest research results from this very specialized field.

Book Description
Fluvial-Tidal Sedimentology provides information on the ‘Tidal-Fluvial Transition', the transition zone between river and tidal environments, and includes contributions that address some of the most fundamental research questions, including how the morphology of the tidal-fluvial transition zone evolves over short (days) and long (decadal) time periods and for different tidal and fluvial regimes, the structure of the river flow as it varies in its magnitude over tidal currents and how this changes at the mixing interface between fresh and saline water and at the turbidity maximum, the role of suspended sediment in controlling bathymetric change and bar growth and the role of fine-grained sediment (muds and flocs), whether it is possible to differentiate between ‘fluvial’ and ‘tidally’ influenced bedforms as preserved in bars and within the adjacent floodplain and what are the diagnostic sedimentary facies of tidal-fluvial deposits and how are these different from ‘pure’ fluvial and tidal deposits, amongst other topics. The book presents the latest research on the processes and deposits of the tidal-fluvial transition, documenting recent major field programs that have quantified the flow, sediment transport, and bed morphology in tidal-fluvial zones. It uses description of contemporary environments and ancient outcrop analogues to characterize the facies change through the tidal-fluvial transition. Presents the latest outcomes from recent, large, integrated field programs in estuaries around the world Gives detailed field descriptions (outcrop, borehole, core, contemporary sediments) of tidal-fluvial deposits Accesses new models and validation datasets for estuarine processes and deposits Presents descriptions of contemporary environments and ancient outcrop analogues to characterize the facies change through the tidal-fluvial transition
