Coastal Marine Flood Intelligence System – Tamil Nadu
Overview
This project presents an integrated coastal marine flood intelligence system
for Tamil Nadu using SAR-based flood detection, historical flood extent,
cyclone-season recurrence analysis, and cyclone exposure assessment.
Project Structure

2. FINAL_Cyclone_Exposure.ipynb
- Cyclone exposure analysis using NOAA IBTrACS (1974–2024)
- Unique cyclone event counting (SID-based)
- Cyclone intensity classification
- Flood-affected population assessment using WorldPop
