Abstract: A wave propagation model based on the wave action conservation theory was developed and applied to the modelling of wave characteristics and the interaction of wave and current in the Pearl River Estuary, by coupling with a three-dimensional hydrodynamic model. The modelling results show that waves propagating from the open sea would be attenuated significantly because of sheltering by islands and shoaling. Waves incoming from the south can propagate further upstream. The tidal current generally increases the wave heights and the effect of the ebbing flow on waves is significant.
