Abstract:
In Iran, over recent decades, trading program of water permits was developed due to their efficiency in dealing with water scarcity through the use of less water and the creation of released water for consumption with higher value, especially in arid and semi-arid regions. Therefore, in this study, in order to survey the trading program of water permits between farmers, two water allocation programs under non-trading and trading systems were designed based on Interval-Parameter Two-Stage Stochastic Program Model. Then, the obtained results of two programs were compared based on index of released water volume and decrease in water deficiency. For this study, 40 farmlands in Yolmeh-Salian village and 30 farmlands in Sheikhabad village were selected; all the villages used water from the Voshmgir dam located in Aq-Qala County. The study results showed that the water allocation under trading program led to released water in Yolmeh-Salian, with low and high limits of interval by [261/69, 374/71] ×103 m3 and decrease in water deficiency by interval of [298/61,486/64]×103 m3 with protection of benefit by [237/91, 351/57] million tomans (i.e. × 10 rials); and in Sheikhabad, it led to released water by interval of [176,244/12] ×103 m3 and decrease in water deficiency by [228/44,317/04] ×103 m3 with the protection of benefit by [141/39 , 210/10] million tomans, compared to the non-trading program of water permits.
