| Abstract | Coastal zones are highly hazard-prone, ecologically sensitive, biologically productive, and geomorphologically dynamic, particularly when influenced by tidal surges and cyclones. These regions are particularly susceptible to extreme events, including storm surges, high tides, and waves. The coastal strip of the Bay of Bengal, particularly the head Bay area, is prone to these hazards because of its low-lying land, large river drainage systems, tidal creeks, mudflats, and barrier islands. The presence of shallow bathymetry, significant tidal ranges, and a densely populated coastline increases the potential for flooding and inundation due to storm surges. To examine regional ocean seasonal variability and the vertical structure of the water column, a high-resolution (925 m ΓΏ 925 m) regional ocean modeling system (CROCO) was run for an area along the eastern coast of West Bengal and Odisha. The model was initially run with climatological data to establish baseline seasonal and vertical patterns. Subsequent experiments used customized wind stress forcings to simulate cyclonic and severe cyclonic conditions, allowing assessment of the ocean's dynamic response and associated coastal impacts in the West Bengal and Odisha regions. The model generated estimates of monthly volumetric flow for these areas, and analysis identified regions along the coastal zone affected under cyclone and severe cyclone forcing scenarios, offering information on locations most exposed to significant water influx and inundation. |
