In March 2019, Cyclone Idai made landfall near the city of Beira, Mozambique, causing extensive damage. During Cyclone Idai attack, the tide level was relatively low, resulting in no significant storm surge damage. However, severer damage can be assumed with high tide levels. This study analyzed storm surge characteristics based on the damage caused by Cyclone Idai in the city of Beira and developed a storm surge hazard map considering the cyclone class and tidal conditions.
It was found that cyclones in the area move very slowly and are likely to coincide with high tide levels, and that the simultaneous occurrence of a cyclone and a high tide has a significant impact on the damage situation. Furthermore, the worst cyclone course for Beira was identified as WNW. The hazard map developed in this study was widely published in May 2021 and are used for the related plans and capacity building of the Mozambiquan government.
