The 2015 Chennai floods – A rapid assessment

In December 2015, Chennai witnessed massive floods killing about 400 people and displacing thousands. Now, researchers from Interdisciplinary Centre for Water Research (ICWaR) at the Indian Institute of Science, Bangalore, in collaboration with researchers from Indian Institutes of Technology (IITs), Madras and Bombay have assessed the flood related information in the public domain and data from secondary sources and carried out quick first level analyses to develop an understanding about possible reasons for the floods. They observed that the massive floods were a result of a combination of factors; high rainfall intensity, overflowing rivers, global climate drivers, unplanned urbanization, inadequate drainage system and upstream reservoir releases.
