Abstract

Analyzing temporal and spatial changes in precipitation, temperature, and surface runoff is essential for water resources discussions and long-term forecasts for watershed management. Therefore, the aim of this study was to model the time series of inflow discharge to Jiroft and Nesa dams under different climatic conditions. For this purpose, two LSTM and GRU models were used in Jiroft and Nesa dams over a period of 25 and 12 years in the Python program environment. Based on the output results, the model is in its best state when it has reached the convergence point. Based on the output results, the model is in its best state when it has reached the convergence point. In the Jiroft Dam LSTM model, the RMSE criteria for training and testing the model were 0.72 and 0.78, respectively, and the MAE values were 0.10 and 0.12, respectively. These values in the GRU model were 0.94, 1.02, 0.15, and 0.20, respectively. Also, in the Nesa Dam in the LSTM model, the RMSE criteria for training and testing the model were 0.11 and 0.10, respectively, and the MAE values were 0.05 and 0.04, respectively. These values in the GRU model were 0.01, 0.09, 0.04, and 0.03, respectively. Also, by planning, it is possible to prevent damage from the dam outlet downstream and to drain and control possible floods as much as possible.
