The water crisis caused by population growth and economic development is the most important threat in human societies. Hashtgerd plain due to the development of socio-economic activities, population growth, increasing water demand and lack of enough resources is facing water crisis. Because of the complexity of the issues related to water resources systems and other systems that interact with it, to manage, plan, and evaluate policies of Hashtgerd plain, system dynamics model based on cause and effect loop diagrams in Vensim PLE software was developed.This model set the interactions between hydrological, agricultural and socio-economic systems of Hashtgerd plain. For calibration of the model, the observed data of hydrology, agriculture and socio-economic condition of the Hashtgerd plain in 1380-1385 period was used. Comparing the simulated results with observations showed that the model was calibrated precisely. So, this model can be used as a decision support tool to assess the effects of any decisions relating to water resources systems, agricultural and socio-economic of Hashtgerd plain.
