Field Investigations of Reference Concentration for Sediment Transport Models

Abstract

The scientific focus of this project is to better understand and predict reference concentration above the seabed. Models of sediment transport depend on parameterization of the near-bed concentration of suspended sediment (or reference concentration ) in terms of dynamical and sedimentological measures. We will evaluate the accuracy and suitability of existing expressions for reference concentration, and based on our field investigations, provide improved definition of this important parameter. This work will be accomplished as part of ONR-sponsored Mine Burial Research Program. It will be coordinated with other investigators who are working together to understand the oceanographic and seafloor processes that affect bottom mines. The principal goal of this research is to develop a specification of the reference concentration that is tested and supported by high-quality field measurements for different sedimentological and dynamical conditions in shallow-water environments.
