EP32A:
Reconstructing Landscape Dynamics and Environmental Signals from Stratigraphy and Relict Landscapes I

Submit an Abstract to this Session



Session ID#: 35439

Session Description:
Landscapes are shaped by sediment transport systems with climate, tectonics, and sea-level as their ultimate forcing conditions, and the physical sedimentary record provides a rich archive of past surface processes and their formative environmental conditions. Quantitative estimates of the hydraulic and morphodynamic conditions of systems that are no longer active enhances our understanding of planetary surface dynamics. Such estimates are also useful for constraining formative environmental conditions, exploring how terrestrial and marine systems respond to external perturbations, for validating models of long-term sediment-transport dynamics, and for unraveling the history of surface processes on other planets and moons. We invite contributions that explore these thematic issues across a wide range of spatiotemporal scales including but not limited to erosional networks, alluvial and fluvial depositional systems, coastal and deltaic settings, and shallow and deep marine environments on Earth or other planets. Contributions from field, experimental, computational, and theoretical studies are all welcome.
