| Abstract |
A three and two dimensional (3D and 2D) numerical models were established to study the storm surge induced by Typoon Maemi in Masan and Pusan Ports. The typhoon landed on the southern coast of Korean Peninsula at 21:00, September 12, 2003 with a central pressure of 950 hPa. The observed maximum storm surge in Masan Port was 230 ㎝, and the computed peak storm surge using the 3D and the 2D models were 238 ㎝ and 208 ㎝, respectively. The observed maximum storm surge in Pusan Port was 89 ㎝, and the peak storm surge of the 3D and the 2D models were 91 ㎝ and 79 ㎝, respectively. The hindcasted storm surge using 3D model was in good agreement with the observed data, and the 3D model at peak time was more accurate than the 2D. The storm-induced currents were computed using the 3D model. The currents in the surface layer of Masan Bay went into the inner bay with 30~60 ㎝/sec, while the currents in the bottom layer flowed out with 20~40 ㎝/sec. |
