Kolkata, India, is one of the most ood-prone cities in the world. It has 4 million people exposed to ooding risks, thanks to 1,800 milliliters of annual rainfall, of which 80% falls during the monsoon season. The topography and tidal range (the height di erence between high tide and low tide) exacerbate the situation, as does high population density.
The ood forecasting and early warning system provides real-time information from over 300 Internet of Things–based sensors, to provide forecasts throughout the city. The system gives updates on ooding, air quality, heat stress, and humidity. The information can be accessed via the K-Flood website and through the K-Flood app, which issues mobile phone alerts and has a monitoring system to inform city residents.
