This volume on continental margin sedimentation brings together an expert editorial and contributor team to create a state-of-the-art resource. Taking a global perspective, the book spans a range of timescales and content, ranging from how oceans transport particles, to how thick rock sequences are formed on continental margins. Summarizes and integrates our understanding of sedimentary processes and strata associated with fluvial dispersal systems on continental shelves and slopes Explores timescales ranging from particle transport at one extreme, to deep burial at the other Insights are presented for margins in general, and with focus on a tectonically active margin (northern California) and a passive margin (New Jersey), enabling detailed examination of the intricate relationships between a wide suite of sedimentary processes and their preserved stratigraphy Includes observational studies which document the processes and strata found on particular margins, in addition to numerical models and laboratory experimentation, which provide a quantitative basis for extrapolation in time and space of insights about continental-margin sedimentation Provides a research resource for scientists studying modern and ancient margins, and an educational text for advanced students in sedimentology and stratigraphy
This workshop designed an integrated investigation of the stratigraphic signature that is created on the shelf and slope portions of continental margins. The goals of the overall program will: add geological perspective to shelf and slope studies of sediment transport, morphology and fine-scale stratigraphy (time scales
My long-term goal within the EuroSTRATAFORM program has been to increase our ability to predict sediment transport in fine-grained regions of the continental shelf through field work and application and further development of models at the Adriatic and Gulf of Lions EuroSTRATAFORM sites. Testing and extending our conceptual and numerical sediment transport models at these sites is an important goal of the EuroSTRATAFORM shelf process studies. The broad objectives of this project are to 1) measure along-shelf, across-shelf and temporal variations in critical shear stress and entrainment rates; 2) compare suspended sediment concentrations measured by bottom tripod with values calculated using measured entrainment rates; and 3) explore the implications of spatial variations in critical shear stress on cross-shelf sediment transport and deposition. During FY07 I was given a no-cost extension in order to 1) serve as lead guest editor of a special issue of Continental Shelf Research devoted to recent studies of hydrodynamics and sediment dynamics in the Gulf of Lions (Xavier Durrieu de Madron and Pere Puig are co-editors); and 2) complete analysis of erosion measurements made in the Gulf of Lions during the EuroSTRATAFORM program.
The global objective of the VIMS involvement in the STRATAFORM program continues to be to improve understanding of the spatially and temporally varying mechanisms that suspend, transport, and deposit sediment on the continental shelf in the vicinity of the mouth of the Eel River specifically and on continental shelves generally. Common objectives of the 1995-1996 and 1996-1997 field campaigns included: (a) to characterize the nature and spatial variability of bed roughness by means of side-scan sonar surveys; and (b) to obtain estimates of time-varying bed stresses over contrasting bottom types at two sites and to evaluate sediment resuspension in response to those stresses by means of bottom boundary layer tripod deployments. Field activities in 1996-1997 were also aimed at supporting the team efforts of the Eel River Plume Study.
Sediment Transport in Aquatic Environments is a book which covers a wide range of topics. The effective management of many aquatic environments, requires a detailed understanding of sediment dynamics. This has both environmental and economic implications, especially where there is any anthropogenic involvement. Numerical models are often the tool used for predicting the transport and fate of sediment movement in these situations, as they can estimate the various spatial and temporal fluxes. However, the physical sedimentary processes can vary quite considerably depending upon whether the local sediments are fully cohesive, non-cohesive, or a mixture of both types. For this reason for more than half a century, scientists, engineers, hydrologists and mathematicians have all been continuing to conduct research into the many aspects which influence sediment transport. These issues range from processes such as erosion and deposition to how sediment process observations can be applied in sediment transport modeling frameworks. This book reports the findings from recent research in applied sediment transport which has been conducted in a wide range of aquatic environments. The research was carried out by researchers who specialize in the transport of sediments and related issues. I highly recommend this textbook to both scientists and engineers who deal with sediment transport issues.
