There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Summary Sentence: The Spring 2022 OSE Seminar Series -- Kyungmin Park, OSE Ph.D. Candidate
Full Summary: The seminar is offered both virtually and in person on the 3rd floor of ES&T in the new Ocean Room. However, the first two weeks are going be entirely virtual.
SP2022 ImageThe dynamics controlling the spatial and temporal expressions of extreme water levels and floods over the coastal wetlands and communities are complex and not well understood due to the limitations of current technologies. One of the challenges in the technologies is limited spatial information that cannot properly capture the dynamics of water levels around residential areas. Leveraging a newly developed high-density network of water level sensors and a city-scale coastal ocean model, this research provides high-resolution information to analyze the underlying drivers of flooding and extreme water levels, and to precisely predict the coastal hazards caused by natural catastrophes. For example, the new frameworks are deployed on the Georgia coast in the U.S. to investigate the flooding drivers during extreme weather events. A set of analyses for the historical events reveals the dominant role of the oceanic adjustment by the hurricane (e.g., coastally trapped signals and change in large-scale ocean circulation) compared to hurricane-induced winds. This result gives new insight into the mechanism of flooding during extreme events. In addition to the analysis of historical events, the model plays a key role in a 3-day forecast system including an early warning system. Predicting the extreme water level with high accuracy, the forecast system has helped decision-makers better prepare for these hazards on the Georgia coast. Given that the Georgia coast is representative of coastal communities along the U.S. southeast coast, the developed tools will be applicable in other coastal cities and help to optimize coastal protection and resiliency against flooding.
