Fossilized Dynamics

The Morphodynamics and Quantitative Stratigraphy group at the Department of Earth System Sciences, Yonsei University seeks to advance our understanding of stratigraphic responses to sediment transport processes and imposed boundary conditions in depositional basins. The morphodynamics of the sediment-fluid interface is influenced by both depositional mechanics and environmental controls. Subsurface architecture is a record of the "fossilized" dynamics of this moving boundary. The research interest lies in improving tools for predicting subsurface spatial architecture across a range of scales using an understanding of sediment transport and surface flow dynamics and their time-integrated preservation in depositional systems. Our research group conducts laboratory experiments to study sedimentation over space and time scales that are usually inaccessible in the field, and use the experimental data to motivate and constrain theoretical models of morphodynamics and depositional patterns. We apply insight gained from physical and mathematical models to field data in order to improve interpretation of paleoenvironments using the stratigraphic record.
