ABSTRACT
Population increases and expansion of agricultural and industrial sectors in many parts of the world have resulted in a growing demand for water. The impact of climate change and widespread water contamination has resulted in many irregularities in the supply and demand structure. Drought events have occurred with smaller recurrence intervals with higher peaks and levels of severity. Many limitations have been imposed on water reuse due to quality and environmental restrictions (see Lettenmiare et al., 1996; Aswathanarayana, 2001). All of these factors have led to a need for integrated water resources management that takes into account all of the system components, the interactions between them, and analyses of risk and uncertainty.
