Research Statement

Extremes, though rare, increase the stress undertaken by water sector owing to the compounding effects of growing population, globalization, and climate change, with implications on food-water-energy security, ecology and environment, critical infrastructures, and emergency preparedness. Recently, India has witnessed an increase in the occurrence of both the hydrologic extremes - floods and droughts; the impacts of which had proved much detrimental to our society and economy, especially due to the lack of any systematic early warning systems and subsequent strategic planning.

Dhanya’s research attempts to generate fundamental scientific understanding of the hydrological extremes along with improvising the hydrological modeling, to provide early-warning methods and adaptation policies for sustainable water resources (WR) management. While confronting this from different angles, her primary focus was to reveal the nonlinear physical linkages between global climatic causative factors and extreme episodes.

Academic Profile

Dhanya is presently a Professor in the Department of Civil Engineering at IIT Delhi. She joined IIT Delhi on November 2011 as Assistant Professor, after her graduation from Indian Institute of Science (IISc), Bangalore in 2011. Her doctoral research was on Hydro-climatological Modeling using Data Mining and Chaos Theory. Five wonderful years spent in Indian Institute of Science (IISc), Bangalore as a Research Scholar and Research Associate enriched her with the nuances of hydroclimatology and chaotic nature of the climate system.
