Water management needs to decide for the water resources development project and future planning based on comprehensive and integrated views. One of the management tools is based on system dynamic approach. This technique has the capability of simulating complex water resource systems to support decision making. The undefined outcome of decisions is revealed through this methodology. The main objective of this method of simulation is its simplicity and rapid learning of system behaivior in present and future conditions. In this paper, the model for water resources and urban water demand was developed with dynamic system for evaluating the trend of resources and demands and the effective parameter on them. The feedback of urban water resources due to the economic, socio and environmental aspects of supply and demand brings about a complex system which can only be analyzed through integrated and dynamic views of the system. The results of the dynamic analysis ofTehranurban water system leads to a tool for understanding and visualizing the reasons of the shortages. This model showes the trend of water balance variation in future as well as the effect of management scenario such as interbasin water transfer, collection and treatment of waste water and demand management.
