Multi-Day Salinity Forecasting in the Vietnamese Mekong Delta: Horizon-Dependent Performance and Interpretation of XGBoost, LSTM, and a Weighted Hybrid
Short-range salinity forecasts can support water management in tide-influenced deltas, but model performance may change with lead time. This study compared extreme gradient boosting (XGBoost), a long short-term memory network (LSTM), and a weighted hybrid for forecasting daily mean salinity one to five days ahead at Va...
