Abstract:Studies of the changing trend of runoff through hydrological prediction can provide auxiliary decision-making for flood control work, which is also an important method for reservoir regulation. Compared with the traditional SWAT model, the runoff simulation model based on LSTM network is more practical and accurate. Focusing on the Fuhe river basin of Poyang Lake, we use rainfall and runoff data collected from Fuhe river basin as model driving data and label data respectively, and achieve the runoff simulation through LSTM network. The results show as follows. In the daily runoff prediction using data observed from meteorological stations, the correlation between measured and simulated runoff is above 0.9 and Pbias is within ±5%, indicating that the model performs well. In the monthly runoff prediction using TRMM dataset, the overall correlation between measured and simulated runoff is above 0.9 and Pbias is within ±5%, illustrating the excellent performance of the model.
