Since December 2015, the Bangalore Urban Metabolism Project has been measuring groundwater depths in 150 locations in Bangalore, every month. This video shows one such measurement, near Avenue Road, made by Giriraj and Sanjeeva, from the Indian Institute of Science.
Although each measurement takes only a few minutes, traveling through Bangalore traffic takes hours. On October 24th, 2016, I joined P Giriraj and Sanjeeva Murthy for a day in which we measured groundwater depth at 15 locations in different parts of Bangalore. Just 15 measurements on a day took 8 hours, thanks to traffic!
