Dr. Sorooshian's research focuses on surface hydrology, primarily in the area of rainfall-runoff
modeling. He has devoted much of his effort to model identification and calibration issues and has
developed special estimation criteria to account for the uncertainties of calibration data. Other
research interests include the application of remote sensing data for characterization of hydrologic
parameters and fluxes and the implication of climate variability and change in water resources. He
also consults on problems related to surface hydrology and flood forecasting.
Dr. Sorooshian is a member of the National Academy of Engineering (NAE); Corresponding Member,
International Academy of Astronautics (IAA); Fellow, American Association for the Advancement of
Science (AAAS); Fellow, American Geophysical Union (AGU); Fellow, American Meteorological Society
(AMS); Fellow, International Water Resources Association (IWRA); Member, Joint Scientific Committee
(JSC) of the World Climate Research Programme (WCRP; Past Chair, Science Steering Group (SSG) of
Global Energy and Water Cycle Experiment (GEWEX) of the World Climate Research Programme (WCRP);
Member, UCAR Board of Trustees; Past-President of AGU's Hydrology Section; member of seven editorial
boards and former editor of AGU's Water Resources Research; Emeritus Member, NOAA Science Advisory
Board; U.S. Member of the Hydrology Commission for WMO. He has served on numerous advisory
committees, including those of NRC, NASA, NOAA, NSF, EPA, and UNESCO.
Among his recent honors are: Robert Horton Medalist, American Geophysical Union (AGU), 2013;
Recipient of the 4th Prince Sultan Bin Abdulaziz International Prize for Water Resources Management
& Protection in 2010; Eagleson lectureship, Consortium of Universities for the Advancement of
Hydrologic Science (CUAHSI), named an honorary Professor at Beijing Normal University, China; and
Fellow TWAS, The Academy of Sciences for developing countries. Professor Sorooshian delivered the
William Nordberg Memorial Lecture at the Goddard Scientific Colloquium in 2004, and he is the
recipient of the NASA Distinguished Public Service Medal, 2005 - "For your distinguished record in
providing scientific leadership for global water cycle research and assuring that NASA science is
well integrated into international programs."
In 2007, the United Nations Educational, Scientific and Cultural Organization (UNESCO) named the
Center for Hydrometeorology and Remote Sensing (CHRS) at UC Irvine and the National Science
Foundation Science and Technology Center for Sustainability of Semi-arid Hydrology and Riparian
Areas (SAHRA) at the University of Arizona joint winners of the 2007 Great Man-Made River
International Water Prize. This is the first time it has been awarded to U.S. institutions.
Sorooshian was the founding director of both research centers.
He was appointed to the Council in 2009. In 2018 he stepped down and was named a CCST Senior Fellow.
