مدیریت یکپارچه منابع آب در بخش‌های کشاورزی، شرب و صنعت با استفاده از نرم افزار WEAP (مطالعه موردی: استان قم)

In this research, the water resources evaluation and programming system (WEAP) was used. The model based on water supply and demand nodes 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 (2020 to 2039) 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, are able to cover part of the need at an annual rate of one percent. In addition to meeting the province's water demand from renewable sources, Restore underground water resources with an annual growth rate of one percent. 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 and the aquifer of the province by 20% will be restored. If the current situation (reference scenario) is followed, due to the natural increase in water demand due to the growth of population and industry, there will be a deficit of about 40% in renewable water sources, even with the upcoming drought periods.
