Based on the ultra-shallow water storm surge theory proposed by Qin and Feng[1] (1975)

an ultra-shallow water storm surge model

taking into consideration the effect of the earth's rotation and the quadratically depth-varying eddy viscosity

is developed. Using the model wind stress fields as a guide for representing the effect of wind stress forcing in our model

a numerical investigation of the Bohai Sea wind surge is made. As a better means for solving the mathematical model

the Galerkin finite element technique is employed in numerical solutions. Under the control of the main weather situation

namely

the cold wave combined with the extratropical cyclone

two storm surge processes experienced on the Bohai Sea are simulated numerically. It is found that the experimental results

in the main

are in agreement with the observations.
