Dynamic Coastlines: Advancements in Understanding of Coastal Hazards and Climate Change Impacts

Session ID#: 159972

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, 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, storms, earthquakes, or ecosystem function.
