Simulation and Detecting Streamflow Fluctuations using Weap Model

Abstract

In This study the need for water transferring in different levels of agricultural development was investigated in the form of a water transfer plan from Sulgan (Vanak) to Khanmirza. In all the scenarios of this group in weap model, implementation of the water transfer plan from Sulgan to Khanmirza Plain (Vanak Dam Project) is considered. Scenarios include implementing an artificial recharge plan as well as increasing the area under cultivation and irrigation efficiency to balance the Khanimarza plain. The results of the first scenario showed that to balance the groundwater, at least 45 million cubic meters of water must be transferred from Sulgan to Khanmirza Plain annually. The results of the second scenario indicated that if Sulgan water is fully transferred to Khanmirza, the area under cultivation can be increased up to 21000 hectares. The results of the third scenario showed that if Sulgan water is fully transferred to Khanmirza and the a pressurized irrigation plan is fully implemented, in addition to the balance of Khanmirza Aquifer, the area of the lands under cultivation can be developed up to 26000 hectares. Furthermore, the fourth scenario indicated that if Sulgan water is fully transferred to Khanmirza (i.e. transferring 200 million cubic meters of water per year) and pressurized irrigation is completely implemented as well as artificial nutrition plan of 10 million cubic meters per year, the area under cultivation can be developed up to 30000 hectares.
