The calculations of seven scenarios in the water resource management tool were calculated and analyzed by DHI WASY in 2018, and currently (February 2011) five scenarios were calculated and analyzed by the Iranian team of integrated management of Zayandeh Roodwater resources in Isfahan 

The zero scenario of the recent calculations called the basic scenario with no change in the current conditions was examined for the mid-term future. It was found that in this case, it should be expected that the cultivated areas of the lower reaches of the Cham Asman dam affected by the river, which is as much as eight networks and irrigation areas, in drought, normal and drought conditions will be 37, 52 and 66%, respectively, the highest cultivated area in three decades. Let the past come. In this situation, it is not possible to meet the environmental needs of the river and the Gaukhoni wetland. The consumption of underground water resources will reach the maximum possible values and the Zayandeh Rood basin will face its consequences. Some other results of this scenario are presented in the table below.

The most important results of the base scenario

The numbers in the table above are in million cubic meters. Also, to get more details of this scenario and all executed scenarios, please refer to the relevant reports.
