Abstract

Increased use of DRIP IRRIGATION systems in the country and farmer's tendency to use more efficient irrigation systems, has caused need to know about parameters and factors that affect irrigation efficiency. This Study was done to examine how water moves in the soil and SOIL MOISTUREre distribution at Weather Station of FerdowsiUniversity of Mashhad. Inthisstudy, HYDRUS 2D/3D Model performed by using data from laboratory and field analysis. Thes imulation results of SOIL MOISTUREina 48 hour period were compared with the results offield measurements. The results showed that the model is very capable in simulating moisture contentin thesoil. Statisticalerroranalysiswas described to estimate model parameters using Maximumerror (ME), Root Mean Square Error (RMSE) and Mean Absolute Error (MAE). Based on the results of RMSE parameter in volume tricsoil moisture, forallintervals and all discharges RMSE was less than 10 percent that it shows that model hashigh ability in SIMULATION. Maximum Error was up to 5% of and Mean Absolute Error was up to 2.05% of volumetric moisture content.
