Modeling Coastal Environmental Change and the Tsunami Hazard

The hazard from earthquake-generated tsunami waves is not only determined by the earthquake’s magnitude and mechanisms, distance to earthquake area, but also geomorphology of nearshore onshore areas, which can change over time. In coastal assessments, a changing environment commonly taken into account increasing sea-level projected values (static). However, changes other climate-change impacts influence entire system causing morphological near- (dynamic). We compare run-up same suite tsunamis barrier island-marsh-lagoon-marsh for statically adjusted dynamically sea level bathymetry. Sea-level projections 2000 2100 are considered. dynamical adjustment based on morphokinetic model that incorporates along with impacts. employ Representative Concentration Pathways 2.6 8.5 without treatment Antarctic Ice-sheet processes (known as K14 K17) different projections.
