- Researchers from IIT Delhi and IIT Gandhinagar have developed a District Flood Severity Index (DFSI).
- DFSI factors in the mean flood duration in days, percentage of district area historically flooded, total deaths, injuries and district population.
- The index uses data from the Indian Meteorological Department (IMD) collected annually since 1967.
- Unlike earlier indices focused on flood magnitude, DFSI measures the impact of floods on people and affected areas.
- Patna ranks highest on the DFSI, while Thiruvananthapuram has the most flood events but lower severity due to fewer impacts.
- The index aims to improve flood management by helping identify severely affected districts and guiding targeted interventions.
