Coastal Geomorphology and Morphodynamics
Session ID#: 249618
Session Description:
Coastal landscapes consist of complex and dynamic landforms whose morphodynamics are influenced by autogenic processes, natural external forcings, climate change, and direct anthropogenic interactions. These processes act on and are recorded in the landscape over a wide range of spatial and temporal scales. By extension, coastal zone research is expansive, encompassing both long-term, broad-scale patterns and short-term, fine-scale dynamics. The 2025 Coastal Geomorphology and Morphodynamics session welcomes novel contributions based on field observations, development and application of models, emerging coastal monitoring techniques, investigations of sedimentary deposits, physical experiments, and interdisciplinary research linking coastal geomorphology and/or morphodynamics with ecology, policy, social sciences, and solutions to coastal hazards. We invite studies across diverse coastal settings, from beaches and barrier islands to rocky coasts, coastal dunes, estuaries, deltas, reefs, marshes, mangroves, seagrasses, high-latitude shores, and more. We especially encourage submissions that challenge disciplinary boundaries or introduce new frameworks for understanding coastal morphodynamics.
