Abstract
The worst storm surge hazard by cyclone Nargis caused 140,000 of casualities in Myanmar in the year of 2008. Since Myanmar has less number of experiences of such severe storm surge disasters, it is difficult to estimate the statistic characteristics of such storm surge hazard. The delta area in the southern part of Bago City, in addition, has dense network system of canals and these canals may have significant impact on inundation characteristics aroud the delta. This study developed a Stochastic Typhoon Model at the eastern part of Indian Ocean and estimated the return period of the severe event of storm surge inundation. The developed inundation model accounted for the impact of canal networks. These developed models were then applied to the south eastern part of Myanmar delta and statistical characteristics of storm-surge-induced inundation hazard were investgated.
