RESEARCH CLUSTERS
Fundamental and Applied Hydraulics and Hydrology
"Hydraulics and ecohydrology of rivers (including ephemeral streams) and Environmental pollution assessment and mitigation are the key domains in this group. Study areas cover all types of land uses: pristine, rural to urban. This group has collaborations with the Institute of Mountain Hazards and Environment - Chinese Academy of Sciences, Irrigation Department, Sichuan University, and Saitama University.
Areas: Solving real-world problems of lotic and lentic waters and contributing to the fundamental understanding of lotic and lentic waters and their interaction with land/catchment "
