Session ID#: 9372
Session Description:
Shallow coastal areas are susceptible to long-term and episodic change and, potentially, environmental degradation. Recent advances in theoretical, observational, and numerical modeling techniques have led to improved understanding of the processes of sediment dynamics and morphological change of sandy and rocky coasts in response to storms and long-term variation in wave conditions, sediment supply, climate, and sea level. Reliable forecasts of coastal environments that include subaerial, shallow-water, and biogeochemical processes over time scales of events to seasons to decades are in high demand. This session combines topics that incorporate observations and models to improve our understanding of shallow-water aquatic processes, and associated morphology, stratigraphy, and environmental change.
