Session ID#: 17714

Session Description:
Understanding the feedbacks between solid-Earth deformation, surface processes and landscape evolution requires a process-based approach that integrates observations and models across all spatial and temporal scales. The Earth’s surface is a dynamic interface that evolves through the influence of tectonic and geomorphic drivers. Changes in tectonic forcings generally have spectacular geomorphological consequences. In turn, processes of surface erosion and transport can alter the near-surface stress field and influence fault evolution, uplift/subsidence patterns and surface heat flow. These mechanisms feed back on topography, and thus on the activity of geomorphic agents. This session sets out to explore current research into coupled problems of geomorphology, surface processes and geodynamics. We welcome contributions utilizing a combination of field, experimental, analytical and numerical approaches.
