Abstract:Crop planning and water resources allocation to meet agricultural demand in arid and semiarid regions such as Iran are a serious challenge. One of the procedures to meet this challenge is to devise approaches for determining the optimal crop patterns based on the limited water resources. In this study, a simulation-optimization approach was applied in which soil and water assessment tool (SWAT) has been used for simulating the complex climate–soil–plant relationships. The harmony search (HS) algorithm has been coupled with SWAT to find the optimal irrigation plan and crop pattern in two scenarios in the Azadegan plain in the Karkheh basin in southeastern Iran. In the first scenario, the crop pattern was the variable of the model while in the second one, it was predefined as the existing situation in the plain. The objective function of the coupled model was to maximize the net profit subject to the total …
