Core Viewpoint - The 20th Central Committee of the Communist Party of China emphasizes accelerating the comprehensive green transformation of economic and social development to build a beautiful China [1] Group 1: Water-Sediment Relationship Management - The Yellow River's sediment management is crucial for maintaining its flow and preventing sediment accumulation, which has historically reduced reservoir capacity and raised riverbeds [2] - Since 2002, the Yellow River has conducted 31 water-sediment regulation operations, sending over 3.5 billion tons of sediment to the sea, significantly improving flood discharge and sediment transport capabilities [2][8] Group 2: Reservoir Coordination and Digital Technology - The Xiaolangdi Reservoir serves as a key component in the coordinated management of water and sediment along the Yellow River, enhancing the efficiency of sediment removal [3][4] - Digital twin technology is utilized to monitor and control water flow, with real-time adjustments made to optimize sediment flushing, exemplified by a flow rate adjustment to 2,500 cubic meters per second, three times the usual discharge [4][9] Group 3: Data-Driven Decision Making - The integration of 5.5 billion data points into a digital twin model of the Yellow River enhances predictive accuracy and operational efficiency in water-sediment management [9][11] - The model allows for the simulation of water-sediment dynamics, enabling proactive adjustments to management strategies based on real-time data [10][11] Group 4: Ecological Considerations - Research is ongoing to understand the relationship between water-sediment dynamics and aquatic life, with measures being taken to minimize ecological impacts during sediment management operations [12] - The introduction of advanced monitoring equipment aims to reveal the interactions between sediment changes and fish populations, contributing to biodiversity conservation efforts [12][13]
