Due to the lack of precise data regarding the annual expansion of cultivated lands under the sprinkler irrigation, water requirements for cultivated crops, and WDEL in the region, certain assumptions were made:
ยท       Firstly, it assumed that the development of the sprinkle irrigation system began in 1989 with a linear distribution, which was not unrealistic and was consistent with the annual development of this type of irrigation in the region. Based on this assumption, the estimated expansion of the sprinkler irrigation system from 2004 to 2019 was approximately 11,550 hectares, as shown in Figure 12.
