The allocation of limited water resources, environmental quality and sustainable water use policies are major issues causing growing concern around the world. The inherent and growing complexities of water resource systems: the challenges of water allocation and the frequent necessity to change input data have led to the development of a system of dynamic modeling for comprehensive water resource management. The subject matter of this paper is the application of a system of dynamic modeling for the Gorganrud River Basin. Considering the need for a Decision Support System (DSS) model that considers all factors, running time was also an important consideration for the decision markers, therefore, the water resources and demands simulation model of Gorganrud basin used VENSIM software and output results were calibrated by the well-known water resources planning model WEAP. A comparison of VENSIM and WEAP shows a high level of accuracy, with matching results between the two models. The outputs of the two models were very similar with the difference being that the running time for the WEAP model was longer than for the VENSIM model in a specific scenario with the same computer model (it was more than 10 times). This developed model on VENSIM environment could save computing time and reduce the decision making time for more efficient management. This technique for the development of a model provides the possibility of adding other qualitative models. The temporal distribution of outflow to the sea show that the two models matched completely. Average annual outflow to the sea in the VENSIM model was 276 million cubic per meter (MCM) and on WEAP model was 275 MCM which is less than 0.4 percent difference.
