The simulation shows that the major impact factor on storm surge is the change of the area due to reclamation. The factor of elevated topography due to reclamation is minor. After the reclamation, the extreme high level of storm surge is increased by 1.85~0.09m, decreasing from tail to mouth in Hangzhou Bay. After the planned reclamation, storm surge increases as a whole. The increased peak value is 0.25m at the center of Hangzhou Bay.
