摘要

Dramatic population growth in urban areas with limited water resources with adequate quality and quantity especially in arid and semi-arid areas have resulted in increasing tensions in a reliable water supply. Growth and change of a comprehensive water supply system makes the complex relationship among system's components more sensitive to the operating policies. All changing factors and variables should be considered in system operation in order to provide an understanding of system performance over time to provide reliable urban water supply schemes toward its improvement. In this study, systems dynamic modeling approach is used to simulate the system behavior through time at an integrated fashion. The simplified water supply system of Tehran metropolitan area, the capital of Iran, has been considered as the case study of this paper. The considered water supply system consists of several components which are connected with complicated interactions to satisfy water demands such as drinking water, agricultural farming and industrial requirements as well as many other possible needs. Reliability of this system is evaluated. The results of the developed model can be used as an indicator of the system's state to decide about the implementation of system rehabilitation and reconstruction projects.
