Subash's work focuses on developing a Flood Vulnerability Index (FVI) to assess the risks faced by U.S. coastal cities due to flooding events. By analyzing several factors of three sub-systems viz. natural, socio-economic and institutional, he aims to find out a vulnerability index for the total FVI system incorporating all these three sub-systems. He plans to use 19 several indicators falling onto those three categories which he plans to normalize each parameter before quantifying a value for each category variable. This will allow for a nuanced understanding of flood risks. In the next phase, Subash will apply future climate scenarios to the FVI, exploring how rising sea levels, storm surges, and extreme weather events may further impact these areas. This research will guide decision-makers in prioritizing resources and implementing strategies to mitigate flood risks in the most affected regions.
