Alborz observatory is an EAS array in the heights of Alborez mountain chain near Tehran. For the development of the array, more number of detectors is inevitable. The managing the financial resources and achieving the highest efficiency of the array is important for the project. Therefore, Water Cherenkov Detectors has been used for 9 months in the same way as the previous experiment with Scintillation Detectors in a 4-fold square arrangement. After a hardware calibration procedure, the experimental data set was simulated by CORSIKA code and the experimental restrictions were applied over the data set. In this work, the simulation is calibrated with the real experimental results, and it presents a comparable parameter between the experiment and the simulation. The obtained results show that the simulation is in agreement with the experimental results.
