Sediment Formation in Nearshore Environments: Strength, Rheology, Microstructure, and Stability
Abstract
Our long term goals are to understand how geotechnical and physical properties develop in marine sedimentary deposits on continental margins as a result of various biological, geochemical and mechanical processes. From these considerations we advance our ability to understand how these properties influence sediment deformation and transport processes and the development of final geomorphology. Our studies include predicting the stability of slopes within the continental terrace and distinguishing morphologic features caused by slope failure from those caused by other gravity-driven processes, including turbidity-current flow. A major component is the development of mobility so that we can understand the transition from initial slope failure to the development of debris flows and turbidity currents. Another component is predicting the rheological properties that determine the dynamics of such flows. We are applying our studies to the EuroSTRATAFORM project, within which we collaborate with scientists seeking to model the formation and alteration of nearshore sedimentary bodies.
