Abstract:

Long-term goals are to improve and develop new scientific understanding of nonlinear water waves, including effects of wind and breaking, and their consequence for naval operations especially with regard to remote sensing of the sea surface, ocean structural loading, and ship performance. The objectives of this effort are to understand and simulate 1. The role of wind, currents, and wave breaking on the long-term evolution of wave systems, including discretization, wave group formation, downshifting, direction distribution of energy, and the generation of extreme waves. 2. The morphology of deformed and breaking waves in connection with impulsive hydroelastic loading. a. Anomalous radar scattering sea spikes. b. Splashing bow waves at the bow of combatant ships. 3. Impulsive loading and hydroelastic response of ocean structures due to breaking wave impact. a. Breaking wave impact on ship bows due to slamming. b. Extension of existing loading prediction methods.
