Investigating different scenarios of Jiroft dam water resources allocation using WEAP model
In this study, the WEAP model was used to analyze the continuation of the existing situation (reference scenario) and the impact of implementing the defined scenarios s1 (increasing drip irrigation with 85% efficiency and sprinkler irrigation with 65% efficiency), s2 (increasing the cultivated area)...

| Summary: | In this study, the WEAP model was used to analyze the continuation of the existing situation (reference scenario) and the impact of implementing the defined scenarios s1 (increasing drip irrigation with 85% efficiency and sprinkler irrigation with 65% efficiency), s2 (increasing the cultivated area) , s3 (change in cropping pattern), s4 (water demand management by 20%), s5 (40% reduction of inflow to the reservoir in the planning horizon) and the combined scenarios from these scenarios for the optimal allocation of the Jiroft reservoir water. The results of the different scenarios show that in the reference scenario, the total amount of agricultural demand is 1559.8 million cubic meters, of which 19.7 million cubic meters are not supplied. According to scenario s1, the total amount of agricultural demand is 801.8 million cubic meters, which is fully met, and the amount of dam water storage in this scenario will be 66730 million cubic meters. The results also show that the amount of water demand and unmet water demand does not change in the combined scenario S145 compared to the combined scenario S14. Still, the water storage in the dam reservoir decreases by 66037 million cubic meters. The results of this study have shown that the WEAP model offers the most effective solutions to meet the varying water needs of the Jiroft Plain and reduce the negative effects of drought. Changing the current cropping pattern increases the amount of storage and the unmet water demand also decreases. |
