Abstract

Using mathematical models for IRRIGATION MANAGEMENT have great impacts to increase irrigation efficiency and product amount, in fields. In this study, simulation results by SWAP model for moisture, compared with soil profiles moisture values, measured in the field. Moisture data, measured at three wheat farms in the NEYSHABUR PLAIN, were used to predict moisture. Results show good agreement between simulated and measured moisture values. R2 coefficient values were 0.611 for Farob Roman farm, 0.648 for Haji Abad farm and 0.679 for Soleimani farm, respectively. Model absolute value was between 1.5 to 2.9 percent and root mean square error (RMSE) value was between 1.9 to 4 percent. According to these statistical indices, SWAP model has been able to simulate moisture, in soil profile in different depths and times, accurately. Therefore, SWAP can be used for IRRIGATION MANAGEMENT in NEYSHABUR PLAIN, with relatively sufficient accuracy.
