Professor Slobodan Simonovic has made seminal contributions to the development of systems engineering approaches for the planning, designing and managing of complex water resources systems in the search for sustainable and robust physical and societal solutions, based on stakeholders' value systems and ethical principles. He has utilized probabilistic and fuzzy simulation and optimization for addressing subjective and objective uncertainties in managing water resources systems. Moreover, Dr. Simonovic has contributed to the solution of complex reservoir operations problems; developed effective flood management measures; improved assessment of climate change impacts on local scales; and developed decision support for integrated water resources management. He is Fellow of CSCE, ASCE and IWRA.
