Study on Probable Maximum Typhoon Storm Surge in Maozhou Estuary
Abstract
Based on the analysis of the statistical characteristics of storm surges which have a great impact on the Maozhou estuary,this paper constructs a typhoon storm surge model based on ADCIRC storm surge model and jetsner wind pressure model,calibrates and verifies the parameters of the model through three typical months and ten typical typhoons,calculates the probable maximum typhoon storm surge when the typhoon lands in Macau with the heading direction of 340° by designing different parameter combinations among typhoon center pressure,moving speed,maximum wind speed radius and typhoon path,and simulates the water augmentation process of Maozhou estuary under the probable maximum storm surge.The calculation results can provide a reference for storm surge prevention and mitigation in Maozhou estuary engineering construction.
