Dr. Sayyed-Hassan Tabatabaei is a Full Professor in the Department of Water Engineering at Shahrekord University, Shahrekord, Iran, where he has been a faculty member since 2004. He has close collaboration with water engineering consultant companies in the area of water resources, irrigation and drainage. Prior to joining the faculty he was a consultant/designer member in different engineering companies including: Parsab, Abandish, Abkavosh, Parsrayab, Kamandab and Iranian fisheries organization during 1995 to 2004. Currently he has been supervisor for Irrigation and Drainage section of Behabsad engineering Consultant Company since 2009. He received a Ph.D. degree in Irrigation and Drainage Engineering in 2004 from University of Tehran, Tehran, Iran. His Ph.D. research included the following areas: 1- Removal of heavy metal from wastewater, 2- Preferential flow of water and solute transport, and 3- Seasonal variation of infiltration parameters in furrow irrigation affected by soil texture and field management. He also did his M.Sc. thesis on “Mathematical and management model of groundwater with emphasis on artificial recharge using MODFLOW software (case study)” in Department of Irrigation, College of Agriculture, Isfahan University of Technology, Isfahan, Iran in 1998. He received a BSc. degree in Irrigation in 1995 from University of Tehran, Tehran, Iran. His research interests in water science are in the areas of soil physics, flow in porous media, surface and subsurface irrigation, flow in porous media, groundwater modeling, water and solute transport in soil, wastewater reuse and evapotranspiration. Using of unconventional water such as saline water and wastewater reuse is a topic which he has focused on during the past few years. Generally speaking, he is interested in soil and water contamination and modeling. He is an active consultant for government and companies in these areas. At Shahrekord University, he teaches undergraduate and postgraduate courses in water engineering and soil sciences. He also supervised thesis of a great number of graduate students both at Ph.D. and MSc level where 53 studies have completed and more than 7 thesis are in progress. Dr. Tabatabaei is the author of over 65 international and national journal papers, 85 conference papers and 6 books. He serves as the Editorial Board of the Journal of IWRJ, IJROWA (Springer).
