Integrated land-ocean systems encompass rivers, estuaries-deltas and coastal oceans, with their morphodynamics playing a key role in global hydrological and biochemical cycles. In the tropics, they provide ecosystem services to communities and are very sensitive to global change caused by human development. Tropical land-ocean systems include large rivers providing most of the total water discharge to the ocean, transition landscapes dominated by mangrove forests, highly productive deltaic and estuarine environments, and coastal oceans fronted by coral and sand-shoal reefs. The understanding of their processes and geomorphology therefore provides tools for a rational management of their services and constitutes a top priority at institutions worldwide. This session invites basic and applied studies on the morphodynamics of land-ocean systems broadly defined, with attention to their integration in tropical regions. We particularly welcome studies addressing the connectivity across environments
