Abstract

Abstract

A high-resolution numerical storm surge model in the estuary of Changjing River is developed using the ECOM-Si.Annual average discharge of the Changjiang River is incorporated into the numerical model,and the influential interaction between tide and storm surge is partly taken into account in the model as well.Feasibility of the model is verified to be using eight-case effectual and typical typhoons passing through the Changjiang River Estuary in simulating and forecasting the storm surge and the average error of the resulting storm surge is less than 10 cm.Several numerical experiments are conducted in order to test the sensitivity of the storm surge to the meteorological parameters such as the minimum sea surface pressure and maximum wind radius of typhoon.The effect of interaction between tide and storm surge as well as the discharge on the storm surge are also numerically tested.The sensitive experiment results indicate that the role of the meteorological parameters,Changjiang River discharge,and the tide-surge interaction in the storm surge is remarkable and therefore should be consider in the operational storm surge forecasting.
