The major objective of this study was to develop further understanding of 3D nearshore hydrodynamics under a variety of wave and tidal forcing conditions. The main tool used was a comprehensive 3D numerical model – combining the flow module of Delft3D with the WAVE solver of XBeach – of nearshore hydroand morphodynamics that can simulate flow, sediment transport, and morphological evolution. Su...

The stability of estuarine channel-shoal systems is important for port utilization, navigation maintenance, habitat protection and ecosystem service functions. This paper uses the South Channel Changjiang (Yangtze River) Estuary as a typical example to investigate adjustment mechanism its future trend. combined approaches bathymetric data analysis process-based modeling (Delft3D) are applied. Q...

Abstract. Deriving reliable estimates of design water levels and wave conditions resulting from tropical cyclones is a challenging problem high relevance for, among other things, coastal offshore engineering projects risk assessment studies. Tropical cyclone geometry wind speeds have been recorded for the past few decades only, thus in poorly extremes, especially regions characterized by low nu...

A model that predicts sediment transport due to wind action can be valuable addition to hydrodynamic models to describe the long-term interaction between land and water. This thesis presents the application of an aeolian transport model [Sauermann et al., 2001, Kroy et al., 2002] as a tool for the evolution of coastal nourishments and dunes. The model was originally developed to describe import...

Understanding connectivity between abalone populations and residence times for pelagic larvae within suitable settlement habitats is critical sustainable management of wild stocks ranching schemes. In the Eastern Cape region South Africa, poaching has severely depleted Haliotis midae populations. Rebuilding stock through larval seeding being considered as a potentially viable method, though ham...

Although shoreface nourishments are an increasingly interesting option for coastal managers to counteract coastal erosion, their design is often highly empirical. A better understanding of the way shoreface nourishments interact with the initial beach profile may help to reduce the degree of empiricism in nourishment design. Literature study has shown that numerical modelling is commonly used t...
