The Morphodynamic Trinity: Linkages among fluid flow, sediment transport, and morphology in fluvial systems across scales

Session ID#: 162834

Session Description:
The interactions between fluid flow, sediment transport, and morphology determine the characteristics of fluvial systems on Earth and planetary surfaces. Exploring the relationships between fluid flow and sediment transport yields insights into how particular morphologies arise and the controls that morphology exerts on a river system’s ability to further convey fluid and sediment. This session explores how the linkages within this trinity of surface processes – flow, flux, and form – provide deeper insights into process-based understandings of fluvial geomorphology. This broad session includes studies on fluid flow, erosion, sediment transport, landscape morphology, and/or the connections between them. Submissions of research topics across a variety of environments, landscapes, and spatial and temporal scales are encouraged. We welcome studies using laboratory experiments, numerical models, and/or field and remote sensing observations to investigate the feedbacks between flow, transport, and morphology on Earth’s surface and beyond.
