Development of Phase-Resolved Real-Time Wave Forecasting With Unidirectional and Multidirectional Seas
International audience Abstract The development of phase-resolved real-time wave forecasting is outlined. This framework is an enhancement over previous work in that the algorithm of real-time wave prediction is extended into multidirectional seas by including the wave measurements and components in...
