Sudarshana’s primary research area is statistical hydrology with an emphasis on stochastic hydrological modeling that aims at efficiently using climate information in water resources management. She is interested in river-basin scale multi-reservoir modeling for understanding water-energy nexus using probabilistic hydroclimatological forecasts and identifying the drivers of hydroclimatic variability across different spatial and temporal scale.

Current Projects

Current Research Topics: 

  • Understanding seasonality and effect of spatio-temporal scales on weather regimes.
  • Improving reservoir management using sub-seasonal to seasonal stream flow forecast.
  • Understanding teleconnection between watershed responses and climate indices.
  • Cumulative effects of dams on flow regime alteration and its impact on biodiversity.
