Session Proposal: Dynamic Coastlines amidst Changing Sea Levels: Advancements in Understanding of Coastal Hazards and Climate Change Impacts (AGU25)

OS010
Dynamic Coastlines amidst Changing Sea Levels: Advancements in Understanding of Coastal Hazards and Climate Change Impacts

Session ID#: 247884

Session Description:
Changes along our coastlines threaten growing populations, economic resources, infrastructure investments, and natural ecosystem functioning. Coastal communities and environments are subject to hazards such as sea-level rise, tropical cyclones and other coastal storms, tsunamis, earthquakes, erosion, and subsidence, most of which are further exacerbated by climate change. To mitigate and adapt to the combined effects of climate change and coastal hazards, a thorough understanding of these hazards – including records of how they have changed through time and projections extending into the future – is essential. We welcome abstracts that reconstruct past, document present, or project future coastal change utilizing methods ranging from geological proxy to remote sensing to numerical and statistical modeling techniques. Relevant topics could include coastal studies over various spatiotemporal scales covering topics such as changing sea level, tropical cyclones or other coastal storms (including storm surge flooding), earthquakes and tsunamis, or ecosystem function.
