Abstract

In the conditions of water shortage due to successive droughts or population growth, the management of limited water resources is necessary to increase their efficiency and optimal use, and the management patterns and allocation of water to different sectors should be reviewed. In this research, the water resources evaluation and programming system (WEAP) was used to manage, optimize in Qom province. The model based on water supply including: urban drinking needs and agricultural irrigation needs as demand nodes and rivers and underground resources as supply nodes for a period of 20 years was designed and implemented. Based on this, four scenarios were defined. The results showed that the policies of the two main management components, i.e. reducing water consumption in the agricultural sector at an annual rate of two percent and wastewater treatment at an annual rate of one percent, in addition to meeting the water demand of the province, are able to increase the underground water table at one percent annually. With the implementation of management scenario policies of level "3" at the end of the vision period, water consumption in the agricultural sector has decreased by 50% without reducing the cultivated area or yield, and the efficiency of water consumption has increased by the same amount. If the current situation (reference scenario) is followed, due to the natural increase in water demand due to the growth of population and industry, even with the upcoming rainy periods, there will be a deficit of about 40% in renewable water resources.
