Book Description
It has been long debated whether or not tidal channels meander through space and time. If so, at what magnitude did they meander; and how did their changes in space and time relate to the morphodynamics of salt marsh development and facies configuration of transgressive valleys? Many have argued that the laws that govern the fluvial streams are equally valid for tidal channels and tidal channel networks. However, there is a lack of field measurements to support the aforementioned statements. Further, the dynamic relationship between tidal channel network development and salt marsh evolution was poorly understood in terms of erosion vs. accretion in response to sea-level changes. Also, models of salt marsh initiation and tidal channel development within transgressive valleys in the US Atlantic coastal plains are not well studied as compared with those of the North Sea in Europe. In an attempt to systematically study the dynamic relationships between the salt marshes and tidal channel networks of transgressive valleys and other system forcings (such as sediment supply, sea-level changes, topographic control, and halophyte production), I chose the Great Marsh area at Lewes, Delaware. To better address these issues, other estuarine tidal basins and incised valleys along the Delaware Bay and Atlantic coasts were studied to serve as modern analogs for the support of my findings in the Great Marsh area. The following major topics/themes are covered and explored in this research study: geologic framework of the study area, modern-ancient analogs, sources of sediment supply, morphometric properties of tidal meander planforms, construction of the paleotopography, hypsometric and volumetric analyses of the incised valley fill, Holocene evolution of the Great Marsh, modern analogs of marsh initiation and tidal meandering development, and discussions of various topics such as tidal channel network initiation and development, incised valley system's self-adjustment in response to changes in sea-level and sediment supply, and facies models as applicable to the transgressive incised valley fills. (Abstract shortened by UMI.).

Book Description
This book presents a comprehensive, contemporary review of tidal environments and deposits. Individual chapters, each written by world-class experts, cover the full spectrum of coastal, shallow-marine and even deep-marine settings where tidal action influences or controls sediment movement and deposition. Both siliciclastic and carbonate deposits are covered. Various chapters examine the dynamics of sediment transport by tides, and the morphodynamics of tidal systems. Several chapters explore the occurrence of tidal deposits in the stratigraphic context of entire sedimentary basins. This book is essential reading for both coastal geologists and managers, and geologists interested in extracting hydrocarbons from complex tidal successions.

Book Description
Integration of ichnological information into sedimentological models, and vice versa, is one of the main means by which we can improve our understanding of ancient depositional environments. Mainly intended for sedimentologists, this book aims to make ichnological methods as part of facies interpretation more popular, providing an analytical review of the ichnology of all major depositional environments and the use of ichnology in biostratigraphic and sequence stratigraphic analysis. It starts with an introduction to the historical aspect of ichnology, introducing common concepts and methods, and then continues with parts treating the main depositional systems from continental, shallow-marine and deep-marine siliciclastics, and marine carbonates. The last part is dedicated to the ichnology in hydrocarbon reservoir and aquifer characterization. - First overview in 25 years of the status of ichnological studies in facies reconstructions of all major depositional environments - Written by a selected, well-experienced and specialized international authorship - Provides easy access to the comprehensive and widespread literature

Book Description
This unique richly-illustrated account of the landforms and geology of the world’s coasts, presented in a country-by-country (state-by-state) sequence, assembles a vast amount of data and images of an endangered and increasingly populated and developed landform. An international panel of 138 coastal experts provides information on “what is where” on each sector of coast, together with explanations of the landforms, their evolution and the changes taking place on them. As well as providing details on the coastal features of each country (state or county) the compendium can be used to determine the extent of particular features along the world’s coasts and to investigate comparisons and contrasts between various world regions. With more than 1440 color illustrations and photos, it is particularly useful as a source of information prior to researching or just visiting a sector of coast. References are provided to the current literature on coastal evolution and coastline changes.
