Abstract

Cyclones cause significant loss of life and damage to properties, marine structures/facilities and ecosystems. Cyclone modelling results are used for deriving robust design conditions for coastal and marine structures and facilities. They are also used for emergency planning and decision-making to estimate potential loss of life, damage to properties and marine facilities and to develop rescue and mitigation measures and plan clean-up operations. Royal HaskoningDHV (hereafter RHDHV) has set up a regional wave model covering the Bay of Bengal and its wider surroundings to address these issues. A list of major cyclones in Bay of Bengal that have affected the Bangladeshi coastline since 1970 was initially identified. The 1991 Cyclone (22-30 April 1991) was found to be the second strongest cyclone affecting the coastal areas of Bangladesh since 1945 (after the Bhola Cyclone on 7-13 November 1970). This paper concentrates on the 1991 Cyclone to illustrate the use of numerical modelling to simulate waves generated by cyclones. The MIKE21 Spectral Wave Model of DHI was used in the study. Sample results of waves from the modelling study are presented in this paper for illustration purposes. The model could be used to simulate any cyclone originating in the Bay of Bengal and its surroundings. The methodology described in this paper for modelling cyclone waves in the Bay of Bengal could also be applied to simulate cyclones at other sites around the world.
