Session Description Coastal hazards including tropical storms and tsunamis are among the deadliest natural hazards in human history, collectively likely responsible for more deaths and economic losses with changing climate and rapid coastal development. This session will discuss the impacts of two major coastal hazards: tropical cyclone induced coastal flooding and tsunamis from their source mechanism, wave characteristics to coastal morphological change. Both storms and tsunamis commonly lead to varying degrees of coastal flooding, coastal erosion, human and economic loss, although they do have different causes: tsunamis are generated by large subduction zone earthquakes, submarine landslides, volcanic eruptions, etc, while storm surges are associated with low pressure weather systems (e.g. tropical cyclones or mid-latitude lows). To better understand and prepare for such coastal hazards in a changing environment, we propose this session which covers the following topics: (1) Characteristics of historical and recent storm surge and tsunami events; (2) hydrodynamics (ocean wave, tide, and surge) of coastal flooding considering multiple physical processes associated with typhoon: extreme rainfall, wind and storm surge; (3) hydrodynamics of tsunami waves considering different source mechanism, e.g. earthquakes, submarine landslides, volcanic eruptions, etc; 4) characteristics of sediment transport during storm surge and tsunami; 5) storm surge and tsunami hazard assessment; 6) the potential impact of climate change (sea level rise, storm climatology) on the coastal flooding hazard.
