Research interest

Hillslope hydrology, subsurface hydrology, surface water-groundwater interaction, hydrological modelling, and climate change impact assessment

Research at CNR-IRPI: He is working in the project “Hydrological modelling by using hydro-meteorological data derived from ground and satellite stations”, wherein what-if scenario-based flood forecasting is to be performed for the Umbria region.



Soumyaranjan Sahoo was born in Cuttack, Odisha, INDIA in 1988. He received Bachelor of Technology (B. Tech) in Agricultural Engineering from Odisha University of Agriculture and Technology in 2011. He completed Master of Technology (M. Tech) in ‘Water Management’ from Indian Institute of Technology (IIT) Kharagpur in 2014. He received Ph.D. from IIT Kharagpur in 2021. The title of his thesis is “Hillslope-based Surface Water-Groundwater Interaction Modelling for Land Use and Climate Change Impact Assessment”.
