Bay of Bengal and Storm Surge and Salinity Model
The Bay of Bengal Model, developed using Delft3D Version 4, is a sophisticated 2D hydrodynamic model created by CEGIS. This model has been extensively applied in numerous government and private projects in Bangladesh. Key applications include determining the impact of storm surges and setting required crest elevations for thirteen polders under the Coastal Embankment Improvement Program (CEIP II) and assessing sea level rise impacts on water, agriculture, and infrastructure under a Department of Environment (DoE) initiative in 2017. In 2019, the model evaluated the combined effects of sea level rise and storm surges on key highways in the Chattogram Coastal Zone, led by the Roads and Highways Department. The model was also employed in 2021 to aid the Water Development Plan for Maheshkhali-Matarbari (MIDI) in Cox’s Bazar. The model integrates river discharges, tides, storm surges, and cyclone-induced waves, accounting for various dynamic processes and climate change impacts to realistically simulate flooding and coastal inundation.
