Dr. Niu Jun, Associate professor
Dr. Niu Jun was born in Anhui Province of China in 1980. He obtained his Ph.D. degree from the University of Hong Kong (HKU) in 2010, and was as a Post-doctoral Fellow in the Department of Civil Engineering, HKU from April 2011 to May 2014. He is currently an Associate Professor in the China Agricultural University.
Dr. Niu’s research interests mainly are in the study of multi-scale & dominant hydrological processes, exploration and prediction of extreme hydrological events, hydrological processes in agricultural lands,and assessment of regional hydrological and ecohydrological impacts of climate change. Among his major contributions to research, Dr. Niu: (1) explored the drought evolutions in terms of meteorological, hydrological and agricultural droughts in South China using numerical simulations; (2) identified the dominant hydrological variabilities of the Pearl River basin in South China depicted by the Indian Ocean Dipole over the past five decades; (3) revealed the driving factors of the basin-featured floods and droughts in the Pearl River; (4) developed a scale-controlled synthetic generation of streamflow time series for providing a basis for the design of roads and bridges and planning/operation of water resources systems; and (5) modified the standard Variable Infiltration Capacity (VIC) model, by incorporating a mechanistic description of vegetation-type specific responses of both stomatal resistance and leaf area based on plant physiological studies, to assess the hydrologic response to the elevated CO2 levels.
