Recent Developments in Modeling Coastal and Estuarine Morphological Processes and Applications to Coastal Flood Management and Erosion Protection

This paper presents a brief review of recent developments of integrated coastal/estuarine models for simulations of coastal and estuarine morphological processes and applications to coastal flood management and erosion protection. It emphasizes the advancement of the integrated coastal models to simulate coupled coastal hydrodynamic and morphodynamic processes by taking into account the combined effects of astronomical tides, waves, winds, river flows, and their complicated interactions with beach erosion, sediment transport and morphological changes in coastal and estuarine waters. It also gives an engineering application example case done by the NCCHE's models for simulating flood and morphodynamic processes in an estuary which were driven by a hypothetical event due to hazardous storm and flood with a100-year return period.
