The coastal zones of northern Odisha coast, western Bay of Bengal, are highly exposed to natural forcing. These regions are vulnerable due to natural hazards such as cyclones, tsunamis, floods, shoreline/beach erosion and sea-level rise. Further, the increased intensity and density of the extreme events in the recent decades have contributed more to the coastal vulnerability, thereby causing floods and inundation. Therefore, there is a need of sustainable use of the coastal zone with proper management practices. In this context, coastal vulnerability index (CVI) has been proved as an effective method for assigning the vulnerability status to any coastal zone. The present research work aims to develop a CVI by integrating risk values of nine input variables and to segment them into low, moderate, high and very high vulnerability categories as per their degree of vulnerability. The study area exhibits a long 273.8 km coastal tract, and about 9.6% of the coastal tract is under very high vulnerability category, followed by 29.7% under high vulnerability, 46.3% under medium vulnerability and rest 14.3% under low vulnerability.

基于地球观测技术的印度东海岸奥里萨邦北部海岸脆弱性评估

奥里萨邦北部海岸、孟加拉湾西部的沿海地区极易受到自然强迫的影响。由于飓风、海啸、洪水、海岸线/海滩侵蚀和海平面上升等自然灾害，这些地区很脆弱。此外，近几十年来极端事件的强度和密度增加对沿海脆弱性的贡献更大，从而导致洪水和淹没。因此，需要通过适当的管理实践对沿海地区进行可持续利用。在这种情况下，海岸脆弱性指数 (CVI) 已被证明是一种将脆弱性状态分配给任何沿海地区的有效方法。目前的研究工作旨在通过整合九个输入变量的风险值来开发 CVI，并将它们细分为低、中、高和非常高的脆弱性类别，根据其脆弱程度。研究区呈现长273.8 km的海岸带，其中约9.6%的海岸带处于极高脆弱性类别，其次是29.7%的高度脆弱性，46.3%的中等脆弱性，其余14.3%的低脆弱性。
