Numerical simulation of waves and storm surge induced by the Gonu tropical cyclone in the Chahbahar Bay area

The Gonu tropical cyclone is the strongest storm in the Arabian Sea in which has cause damage in the Iranian south coastlines. The aim of the current paper is to numerically simulate the wave’s characteristics as well as the storm surge during the Gonu event by employing the SWAN wave model and the GETM hydrodynamic model. The simulation duration is one month i. e. from15 May to 15 June 2007. The wave characteristics are compared with the measured data in three measurement stations. The results show that the wave characteristics are reasonably simulated during the Gonu storm event so that the significant wave height is reached up to six meters and the corresponding height was four meters، respectively، outside and inside the Chahbahar bay area. The results show that the storm surge has reached up to 50centimeters in the Chahbahar coastlines which are corresponding to the 6th day of the Gonu storm.
