Abstract：Based on the high-resolution wind field and bathymetry in the Weifang coastal area,annual extreme wave parameters of three calculation points in the-15 meter isobath are obtained by running SWAN model,and the return periods of wave characteristics in different wave directions are calculated by using P-Ⅲ type extreme value distribution.The geographical distributions of seasonal averaged significance wave height and mean period in Weifang offshore area are analyzed.Storm processes from 1994 to 2013 are analyzed based on ADCIRC hydrodynamic model.The maximum water level and the maximum storm water level of every storm process in Weifang Port are calculated,and water level and maximum storm surge are calculated by Gumbel method and P-Ⅲ method.This study can provide not only references for simulation and prediction of the characteristics of wave and storm surge,but also a scientific basis for the marine engineering construction and architectural design in the Weifang coastal area.
