Coupled Modeling Approach to Quantify Shoreline Erosion and Beach Morphology due to Passing Vessels
Publication: Ports 2022
ABSTRACT
Deep-draft vessel waves are found to play a significant role in shoreline erosion due to their larger height and longer period. Currently there are many numerical models that predict shoreline changes caused by natural processes such as tidal currents and waves. However, a modeling system that efficiently simulates both vessel-induced hydrodynamics and morphological changes is not typical. A modeling system was therefore developed by coupling two highly validated models used for predicting vessel hydrodynamics and morphological processes. The modeling system also utilizes historical ship tracking data to automatically process relevant vessel events over a given period to be used for predicting long-term shoreline impacts. The paper discusses the development and advantages of the modeling system using applications involving shoreline sections in bays where deep-draft vessels are frequent. The paper presents results of hydrodynamics as well as sediment erosion, transport, and deposition associated with vessel events.
