Causes, Effects, and Solutions to Urban Flooding

Chennai, India

This project used satellite imagery, digital elevation models, and crowdsourced street data to model three aspects of the 2015 floods in Chennai, India: 1) the historic encroachment of impermeable surfaces leading to increased flood risk, 2) the effect on access to critical emergency services during the flood, and 3) opportunity sites for flood water retention/detention to mitigate future flooding.
