Advanced Operation of Tandem Arranged Multipurpose Dams Using Long-Term Ensemble Rainfall Prediction

Key Points

• The aim is to enhance the operation of multi-purpose dams using long-term ensemble rainfall predictions to improve flood control and water resource management.
• Proposed a method for decision-making in tandem multi-purpose dams based on specific target reservoir capacities.
• Integrated ensemble forecasting to predict downstream dam operations with varying operational terms.
• Set new guidelines for maximum water levels and operational management in hydropower facilities.
• Confirmed significant increases in hydropower generation without compromising flood control.
• Reduced ineffective discharge and maximum outflow during floods.
• Enhanced management of water resources through targeted operational strategies.
