海洋科学学术讲座预告第427期：The Effect of Tide-Surge-River Interactions on Delaware Bay Estuary Coastal Flooding

报告内容简介：

      Tropical cyclones (TCs) can generate extreme coastal storm surges and river flooding, causing devastating damage to coastal communities. However, little is known about how interactions between storm surges and river floods exacerbate coastal flooding, especially at the top of high tides. Through a detailed modeling analysis of the Delaware Bay Estuary (DBE), the total water level (TWL) induced by storm surge, river flow, and tides were separated into components to investigate the contributions of the different factors and their interactions to coastal flooding. Based on the simulation results, three distinct zones along the DBE were identified, including a transition zone where the interaction of a river flood and storm surge can result in compound flooding. Information obtained from this study can be used to support the development of adaption and mitigation strategies for coastal communities.
