Modelling the impacts of Hurricane Ike on the Texas coast using a fully coupled TELEMAC-TOMAWAC-SISYPHE model

Hurricane Ike, a category 4 hurricane, made landfall near Galveston, Texas on the 13th of September 2008. A fully coupled TELEMAC-TOMAWAC-SISYPHE model was developed to predict sediment transport and associated morphodynamics resulting from the passage of Hurricane Ike. The predicted hydrodynamics were validated against observed tidal elevations, currents, waves and inundation. The predicted sediment transport pathways and resulting bed elevation change were compared with assessments of coastal impacts associated with Hurricane Ike. The model results show good agreement with observations and demonstrate the ability to predict hydrodynamics, sediment transport and morphodynamics associated with hurricanes using a fully coupled TELEMAC-TOMAWAC-SISYPHE model.
