Abstract

The country's water resource depletion is a problem that exerts its effects in various areas such as climate, agriculture, vegetation, wildlife and so on. In this study, using systematic and holistic system dynamics approach, we will analyze and analyze the dynamic relationship between municipal water level and urban green space in Zarghan city. This system model has been simulated and analyzed with Vensim Dss software.
The overall results of the simulations and scenarios are that heat islands and construction are among the most important factors in increasing water consumption in the system. Also, the most important factors affecting the reduction of water use, type and amount of vegetation water use in Zarghan municipality are as follows: Annual survey and model simulation for 1385 for twenty years. Actual data were collected from 1385 to 1395. In this regard, the quantitative results of the model show that by reducing the water consumption by defined methods per square meter by 40%, saving 42 million cubic meters of total water over a 20-year simulation period.
