Sediment Erosion and Redistribution in Fine-Grained Shelf Environments

Abstract

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.
