Wave setup is the increase of water level within the surf zone due to the transfer of
wave-related momentum to the water column during wave-breaking. Wave setup contributes to the
total water height in storm and become dangerous to coastal construction. This study presents
some results on wave setup with storm surge using numerical model and empirical model. It also
estimates the contribution of wave setup in total storm tide level at coastal and estuarine region of
Hai Phong. Results show that wave setup at coastal and estuarine region in Hai Phong contributes
about 25% to 40% of sea level surge in storm, 32% on average.
