Research Interests

Dr. Pokhrel's research focuses on improving the understanding of the changes in global/regional water cycle in response to the combined effects of human activities and climate change. In particular, the changes in various components of the hydrological cycle, as caused directly by human activities such as reservoir operation, land use change, irrigation, and groundwater pumping, constitute the foundation of his research interest. Dr. Pokhrel's past work involved the representing these human factors into global/regional hydrologic, climate, and Earth system models; he has also worked on the integration and assimilation of various in-situ and satellite-based data (e.g., GRACE, SMAP) into these models. His current research efforts are focused on using these modelling tools and satellite data to assess changing hydrologic systems globally and in specific regions including the central and southwestern US, Amazon River basin in south America, and Mekong River basin in southeast Asia. The emphasis of his projects is on the sustainability of surface and/or groundwater resources and agricultural systems under climate change and growing influence from water management to meet rising food-energy-water demands. Dr. Pokhrel's research is funded primarily by NSF and NASA. He is a recipient of the CAREER Award from the NSF, and numerous other research and teaching awards including the "MSU Teacher/Scholar Award" and the "Withrow Distinguished Scholar Award". He currently serves as an Associate Editor for Journal of Hydrology, Water Resources Research, and Scientific Reports (Nature).
