Interannual Variations of Vegetation Optical Depth Are Due to Both Water Stress and Biomass Changes

Published in Geophysical Research Letters, 2021

This paper re-examines the commonly held assumption that VOD interannual variations are proportional to interannual variations in biomass, and shows that the assumption for the most part, is invalid.

talks

Stormwater drainage

Published:

This talk presented retrofitting measures for the storwater drainage system of the IIT Madras campus. The 650-acre campus’ stormwater drainage network is more than 50 years old fails frequently during big storms. The talk focussed on presenting a 3-phase expansion plan to include-

  1. New culverts at frequently-flooded areas with high traffic
  2. Stormwater drainage basin to control overflow from the campus lake
  3. Sustainable stormwater drainage elements such as swales, greenroofs, etc.
