**About the Editor**

**Slobodan P. Simonovic** has made seminal contributions to the development of systems engineering approaches to the planning, designing, and managing of complex water resource systems in the search for sustainable and robust physical and societal solutions, based on stakeholder value systems and ethical principles. He has utilized probabilistic and fuzzy simulation and optimization to address 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 resource management.
