Hydromorphological processes, including sediment erosion, transport, and deposition, are crucial in shaping open water environments such as rivers, estuaries, lakes, and reservoirs. Accurate predictions of these processes are essential for both research and practical applications. Over the past decades, numerical models have become vital tools in hydraulic engineering and geosciences for simulating these complex interactions. With advances in algorithms and computational power, high-resolution simulations of water, sediment, and air interactions are now possible. Additionally, the growing availability of high-quality validation data from lab experiments and field studies has enhanced these models, leading to new insights into processes like dune development, riverbed armoring, and density-driven transport. As a result, next-generation numerical modeling techniques are enabling the exploration of intriguing questions in hydromorphology. Furthermore, Artificial Intelligence (AI) is emerging as a reliable alternative in these studies.

This session aims to unite scientists and engineers who develop, improve, or apply numerical models of multiphase flows for sediment transport in open water environments. We welcome contributions that cover a range of spatiotemporal scales, from small-scale particle entrainment to large-scale morphological development, in various settings including rivers, lakes, reservoirs, estuaries, and coastal areas.

Contributions may include, but are not limited to:
- Sediment entrainment processes, ranging from cohesive sediments to armored riverbeds
- Bed load and suspended sediment transport, including flocculation
- Simulation of sediment management for the planning, operation, and maintenance of hydropower plants
- Design and assessment of river restoration measures
- Navigation-related issues, such as sediment replenishment, dredging, and erosion caused by ship-generated waves
- Flood-related impacts, including the long-term effects of morphological bed changes on flood security
- Eco-hydraulics, focusing on flow, sediment, and vegetation interactions
- Density-driven transport mechanisms.

Please note that the session “Hydro-morphological Processes in Open Water Environments – Measurement and Monitoring Techniques” shares a similar focus. If your contribution is more centered on measurement and monitoring, we encourage you to submit your abstract to that session instead.
