Three main areas could account for the consumption of this amount of water, namely domestic, industry, and agriculture. Concerning domestic water consumption, according to the Statistical Centre of \cite{iran2019} the total population in 2019 was 144,505 individuals, with 67,042 residing in urban areas and 77,463 residing in rural areas. The per capita consumption of potable water for domestic use in Iran is reported to be around 157 L per day \cite{j2016}. Consequently, the consumption of drinking water in 2019 was approximately 8 million cubic meters. Assuming that the population has doubled during this period of 16 years, domestic consumption has only increased by 4 million cubic meters. In addition, the use of absorption wastewater wells in rural areas and treated surface wastewater in urban areas, return a very high percentage of this volume of water to the basin. Therefore, water loss in this sector was a small portion of the overall water volume that has drifted out. Given that the Eskandari watershed is primarily an agricultural area rather than an industrial one, the growth of the industrial sector does not significantly impact water consumption in the region. Consequently, drifted-out water volume water cannot be attributed to population growth and industrial development, leaving the agriculture sector as the sole plausible explanation.
