英文摘要: The Indian Ocean region is one among the six major cyclone prone regions in the world with an annual average of about five to six cyclones. Prior studies conducted for this region are location-specific and confined to storm surge characteristic and associated inundation. A detailed study to develop precomputed scenarios on storm surge and inundation maps for the entire Indian coast is still lacking for emergency preparedness. An effort in this direction can drastically reduce preparedness time in the eventuality of a real cyclone approaching its landfall location for effective coastal zone management measures. The present study is a motivation in this direction leading to the generation of a comprehensive data set on storm surges and associated coastal flooding for entire Odisha coast located in the east coast of India and that can be extended to other coastal regions as well. Historically, the Odisha State experiences highest number of cyclone strikes with the highest risk of exposure to storm surge and inundation. The novelty of this study is in the preparation of a comprehensive storm data set using synthetic tracks simulated with various combinations of landfall location, angle of attack, intensity, and forward translation speed. It also generates possible storm surge and inundation associated with intensified cyclones expected in a changing climate scenario. Further, the study also correlates power dissipation index with storm tide all along this coast. The distribution of surge height follows a third-order polynomial to wind speed. An in-depth analysis was also carried out to understand the characteristics of storm surge height and extent of coastal inundation with respect to coastal geomorphology, angle of attack, and varying forward speed of cyclones. The authors believe that information and analysis from this comprehensive data set will have immense potential in understanding the impacts from tropical cyclone climatology and disaster management applications. © 2017 Royal Meteorological Society Citation statistics:
