Research progress of compound flood in coastal cities

Abstract

Abstract Facilitating the development of cities in coastal areas is an economic strategy from a global perspective. Currently it can be seen that large developed cities in many countries are distributed along the coast. However, in recent years, with the influence of climate change, sea level rise, cyclone changes and land subsidence, the frequency of compound storm floods has been increasing. More academics begin work on compound storm flooding. It can be found that the development of the flood model has experienced a process from ordinary static simulation to one-Dimensional-three-Dimensional coupled model. At present, there are mainly hurricane model and hydrodynamic model to study the composite storm flood. Through current storm flood models, it is known that the intensity and frequency of storm floods will increase under current climate change conditions. At the same time, this paper also looks forward to the models, and proposes an improvement plan to increase the application scope of the model.
