Evaluating theWater Allocation to WUA at Alborz SchemeWith MIKEBASIN and its Sensitivity Analysis

In order to manage the fair allocation to water users associations (WUA) s،application of analytical and integrated method is the way to increase the capacity of water supply and appropriate use of these resources. Various models and tools have been developed in recent years to simulate equitable allocation of water issues and supply and demand analysis. MIKEBASIN model is one of these capable models. In this study، water resources planning at 5 WUAs of the watershed of Babol river was performed by MIKEBASIN model. These areas have demand and its own allocated water and 15 years data from each demand point was entered into the model. Results showed that in time water of Babol River was not adequate to supply WUAs demand. Therefore، using wetlands and groundwater is essential to supply their demands. Also، the results of sensitivity analysis showed that the discharge of watershed had the most effect on the outputs of model among all other parameters. Therefore this parameter should be measured or be predicted accurately.
