River deltas are among the most valuable ecosystems on Earth, providing coastal protection against storm impacts and sequestering carbon. However, these coastal systems are threatened by climate change, land loss, and anthropogenic activities, with long-term sustainability dependent on sediment delivery, biogeochemical cycles, and human interventions. Understanding the dynamics of deltas is particularly challenging due to the multiscale interactions between vegetation, sediment transport, water flow, and biogeochemical cycling of carbon. Predicting how these processes will impact deltas requires cross-disciplinary research, including advances within hydrology, geomorphology, ecology, and biogeochemistry. In this session, we encourage the presentation of research that fills knowledge gaps such as carbon budgets, water and sediment residence time, impacts of extreme events, upscaling. We welcome research including remote sensing, numerical modeling, experimentation, and in-situ field measurements to better understand subaerial and subaqueous coastal processes and improve predictions of coastal resilience at landscape, regional, and global scales.
