Current Research

"Role of surface and sub-surface soil moisture for vegetation functioning."

I explore how vegetation functioning correlates with the surface and deep soil moisture: (1) across different climatic regimes and vegetation types spatially and how (2) correlations change during dry months temporally.

Past Research

1. "Temporal scale dependent sensitivity analysis of surface water-groundwater interactions."

For a simple model of head response in a semi-infinite aquifer due to hydro peaking, I analyze the sensitivity of parameters in different temporal scales. For this, I first decompose the time series of head response into different temporal scales using Discrete Wavelet Transform (DWT). Then, I perform a global sensitivity analysis to rank sensitive parameters on each temporal scale.

I build the 1-D hydraulic model of the Ouémé river in Benin, Africa, and the Naryn river in Kyrgyzstan, Central Asia. Then I perform hazard analysis for the floods of different return periods.
