Hybrid SARIMA—GRU Model Based on STL for Forecasting Water Level in Red River North Vietnam

Abstract

The Red River Delta is formed by the Red River System, which is the greatest river system in Vietnam’s northern region. The primary river, the Red River, has neither an water storage dam nor a hydroelectric dam. Because of this disadvantage, water level forecasting is critical for regulating agricultural water in Vietnam’s second-largest rice-producing region. We present a model to anticipate the water level of Red River water level in Viet Tri, which is near Ha Noi, in this study. The new model is known as the SARIMA-GRU hybrid model, which can fully exploit seasonal patterns in the data. In comparison to the single models SARIMA and GRU, as well as the model ARIMA-RNN, published by Xu et al. in 2019, the new model has produced better results.
