Urban Flood Model for Bangalore City

Floods and consecutive inundation in urban areas, especially in Bangalore City (BBMP area) during the rainy season have become a regular phenomenon. Urban floods are responsible for severe damages to the public and private property, as well as loss of life of citizens. Though urban flood is an calamity that needs to be addressed, the floods provide an excess amount of water to the city, which can be channelized and utilized as a positive, surplus resource. To mitigate and manage these flood events, the Indian Institute of Science (IISc), Bangalore, in association with Karnataka State Natural Disaster Monitoring Center (KSNDMC), Bangalore, has taken up a project titled, “Urban Flood Model for Bangalore”, funded by Department of Science and Technology (DST), Ministry of Science and Technology, Government of India under “Demand Driven Convergent Water Solutions in Mission Mode”. the project intends to develop an urban flood model, capable of simulating hydrologic and hydraulic behavior of storm water in existing and natural drainage systems using high resolution terrain data. This project also aims at creating a huge database for Bangalore in terms of terrain data using LiDAR technology and flo and rainfall data from a high density sensor network, thus improving the accuracy of the urban flood forecasting and management model. The urban flood model will be tuned for the Bangalore city conditions and will be customized for existing and expected urbanization, low lying areas etc. The project also intends to reuse flood water by harvesting and storing, to improve ground water level of the city and to rejuvenate the lakes to address the water crisis.
