Research Areas


  • Downscaling:
    Statistical and stochastic downscaling of rainfall and/or other hydrological variables to access the water resource availability and distribution in future.
  • Stochastic hydrology:
    Single and multi-site generation of daily rainfall and streamflows; Identification of higher time scale memory in hydrological time series. Predictor identification strategies for formulating hydrological models; Partial Mutual Information.
