A huge disaster was induced in Myanmar by the attack of Cyclone NARGIS on May 2nd, 2008. The Yangon port which is the largest in Myanmar was heavily damaged while the port operation was urgently necessary to carry the emergency supply by waterway to the Ayeyarwady Delta severely devastated in storm surge. A field survey was carried out in order to study on the disaster characteristics in the harbor and to obtain the information for recovery planning. As the results in the survey, the storm surge deviation above the high water level was measured up and it was about 1.8m in the northern side of the Yangon River. The floating pontoon and connecting bridge parts in the jetties were mainly damaged in the storm surge of harbor. The number of damaged jetties was 28 out of the total number of 37 in the harbor.
