Flood in the GBM Delta

  • Kalyan Rudra
Part of the Geography of the Physical Environment book series (GEOPHY)


Bengal is the ultimate outlet of 89,000 cumec water carried by the GBM system during the monsoon months. The flowing water often overtops the bank and submerges low-lying areas in the rainy season (June to September). The event is often described as disaster due to failure of protective measures to combat the hydrological extreme. The attempts of flood control, be it through building of embankments or by routing of flow from the reservoirs, did not work as expected. It is now understood that total freedom from flood is neither possible nor desirable. The strategy must switch over to preparedness-driven approach from ongoing relief-centric flood management.
