This article evaluates the impacts of ‘Fani’, a category four cyclone on the shoreline and ecology of the largest brackish water lagoon of Asia, Chilika, on the East Coast of India. The cyclone forced open two New Tidal Inlets (NTI) along the northern shore of the lagoon’s outer channel leading to erosion of the embankments and spits. The average rate of change due to cyclonic storm ‘Fani’ was – 6.12 m while 66.03% of the total transects registered symbol of erosion along the shoreline of Chilika lagoon. Post Fani the information made available on its impact on Chilika was minimal which made us to look into published news articles, online news channels,past published scientific literature to corroborate the likely impact of such erosion and new tidal inlets on the lake ecosystem. Experts differed on their opinions on how the plankton, fish, seagrass and critically endangered Irrawaddy Dolphin would respond to the salinity changes in the lake aftermath of the cyclone. Some of the impacts of ‘Fani’ on the lake shoreline and ecosystem were imminent, such as the opening of tidal inlets and spot death of three Irrawaddy dolphins; whereas, long-term impacts such as changes in the biomass and composition of plankton communities, fish and bird population in the lake are primarily unknown and warrants further detailed investigation. Nevertheless, the study asserts that cyclone driven shoreline damage can impact lagoon ecosystem by bringing in a rapid change in the salinity field

快速严重的气旋风暴Fani对印度奥里萨奇利卡湖的形态动力学和生态影响的快速评估

本文评估了“ Fani”（第四类旋风）对印度东海岸亚洲最大的咸咸水泻湖Chilika的海岸线和生态的影响。旋风迫使沿泻湖外河道北岸的两个新潮汐入口（NTI）打开，导致路堤和吐口被侵蚀。气旋风暴“ Fani”造成的平均变化率为– 6.12 m，而占总断面的66.03％则记录为Chilika泻湖沿岸的侵蚀标志。Fani之后，关于其对Chilika的影响的信息很少，这使我们只能研究已发表的新闻文章，在线新闻频道，过去发表的科学文献，以证实这种侵蚀和新的潮汐入口对湖泊生态系统的可能影响。专家对浮游生物，鱼类，海草和极度濒危的伊洛瓦底海豚会对旋风后湖中的盐度变化做出反应。“ Fani”对湖泊海岸线和生态系统的某些影响迫在眉睫，例如潮汐口的开放和三只伊洛瓦底江海豚的死亡。然而，长期影响如浮游生物群落的生物量和组成变化，湖中鱼和鸟的数量变化主要是未知的，因此有待进一步详细研究。然而，该研究断言，旋风驱动的海岸线破坏可通过使盐度场快速变化而影响泻湖生态系统。例如潮汐口的开放和三只伊洛瓦底江海豚的死斑；然而，长期影响如浮游生物群落的生物量和组成变化，湖中鱼和鸟的数量变化主要是未知的，因此有待进一步详细研究。然而，该研究断言，旋风驱动的海岸线破坏可通过使盐度场快速变化而影响泻湖生态系统。例如潮汐口的开放和三只伊洛瓦底江海豚的斑点死亡；然而，长期影响如浮游生物群落的生物量和组成变化，湖中鱼和鸟的数量变化主要是未知的，因此有待进一步详细研究。然而，该研究断言，旋风驱动的海岸线破坏可通过使盐度场快速变化而影响泻湖生态系统。
