In the recent past, a steep increase in the frequency and intensity of flash floods in urban regions has resulted in significant damage to life and property, necessitating a holistic approach to address the problem. An integrated urban flood model for Bengaluru city, Karnataka, India has been developed with a modular approach, which includes real-time rainfall and weather monitoring, and a rainfall forecast system feeding into a comprehensive hydrologic flood model. An output management and information dissemination channel for timely disaster preparedness and response is integrated in the framework, with active involvement of the government. The framework and outcomes of the system are summarized and presented here.

Abstract


In the recent past, a steep increase in the frequency and intensity of flash floods in urban regions has resulted in significant damage to life and property, necessitating a holistic approach to address the problem. An integrated urban flood model for Bengaluru city, Karnataka, India has been developed with a modular approach, which includes real-time rainfall and weather monitoring, and a rainfall forecast system feeding into a comprehensive hydrologic flood model. An output management and information dissemination channel for timely disaster preparedness and response is integrated in the framework, with active involvement of the government. The framework and outcomes of the system are summarized and presented here.
