CP002
Coastal Geomorphology and Morphodynamics

Session ID#: 253776

Session Description:
Coastal landscapes consist of complex and dynamic landforms whose morphodynamics are
influenced by autogenic processes, natural external forcings, anthropogenic climate change, and direct human interactions. These processes act on and are recorded in the landscape over a wide range of spatial and temporal scales. We welcome contributions based on field observations, models, physical experiments, and interdisciplinary research linking coastal geomorphology and/or morphodynamics with biology, biogeochemistry, ecology, economics, policy, and social sciences. Submissions are encouraged from studies covering a wide range of coastal settings including beaches, coastal dunes, barrier islands, rocky coasts, estuaries, deltas, lagoons, marshes, mangroves, seagrasses, reef islands, carbonate environments, and high-latitude coasts. The “Coastal Geomorphology” session at Ocean Sciences aims to extend a popular AGU session to OSM to showcase coastal, interdisciplinary work at the premier oceanographic conference.
