Numerical Simulations of Coastal Floods and Morphological Changes Due to Sea Level Rise and Hazardous Storm

This paper presents a simulation approach for assessment of the impacts of sea level rise (SLR) on an estuary under complex hydrological conditions such as storm wave, tide, river flood, and sediment transport from rivers to estuary and coast. An integrated coastal/estuarine processes model is used to simulate hydrodynamic and morphodynamic responses to several scenarios of SLR and hazardous storms. Numerical results indicate that this model enables to simulate coastal flooding/inundation, shoreline retreat, and morphological change and respond correctly the interactive impacts of SLR and storms; it is therefore applicable to coastal/estuarine water planning and management for the purpose of flood prevention and erosion protection against the global mean SLR and hazardous storms.
