Abstract

Artificial neural network is a powerful tool to solve the engineering and technical problems such as water resource problems. In this study, the ability of neural network model for simulating the hydrograph in JAFAR ABAD RIVER was evaluated. It is notable that the FLOOD HYDROGRAPH was estimated 2, 3, 4 and 5 hours earlier using the flood discharges at 2, 3, 4 and 5 previous hours as model inputs respectively. This was carried out using 18 FLOOD HYDROGRAPHs recorded in upstream gauging station. From this dataset, 12 FLOOD HYDROGRAPHs were chosen to train the model and 6 FLOOD HYDROGRAPHs for validation and test the model. The results showed that by increasing the estimation lag time, the accuracy of results decreased and in a given lag time, by increasing the number of input, the accuracy of results increased. The results showed that the amount of efficiency coefficients, which is the representation of performance of FLOOD HYDROGRAPH modeling, is 0.92 and 0.93 for two test hydrograph, respectively. The results also showed that the type of TRANSFER FUNCTION and learning algorithm were the effective factors on model outputs.
