Core Points - The "Model Yellow River" project in Zhengzhou aims to address the challenges of managing the Yellow River by creating an 800-meter physical model that simulates the river's behavior and dynamics [1][3] - The project is part of a broader initiative by the Yellow River Water Conservancy Commission, which introduced the concept of "Three Yellow Rivers" in 2001, including "Prototype Yellow River," "Digital Yellow River," and "Model Yellow River" [3][5] - The model serves as a crucial tool for developing protection and management strategies for the Yellow River, providing necessary physical parameters for simulations and analyses [3][5] Technological Advancements - Starting in 2024, the Yellow River Water Conservancy Research Institute will upgrade the model using modern digital, intelligent, and sensing technologies, enhancing the model's capabilities [5] - Innovations include the first domestic embedded PLC automatic control sand addition system, which allows for automatic control of sediment concentration in the model [5] - The river flow monitoring system utilizes PIV velocity measurement algorithms for real-time monitoring and intelligent identification of river dynamics without tracer particles [5] - The institute has developed the first domestic AI terrain-making equipment for river models, significantly improving efficiency and precision in terrain creation [5] Infrastructure and Equipment - The "Model Yellow River" facility boasts the world's largest flood simulation testing platform and the largest artificial rainfall system [5] - The base is equipped with over 4,000 scientific testing instruments and technical equipment, with automated monitoring systems and artificial rainfall systems being internationally leading [5]

Core Insights - The meeting led by Li Guoying emphasizes the ongoing flood risk as the primary threat to the Yellow River basin, highlighting the need for improved water-sand regulation and flood disaster reduction systems [2][2] Group 1: Flood Risk and Water Management - Flood risk remains the biggest threat in the Yellow River basin, with the imbalance of water-sand relationships identified as a key issue [2] - There is a call to accelerate the improvement of water-sand regulation and flood disaster reduction systems, including the establishment of a comprehensive flood control engineering system and monitoring systems for rainfall and flood disasters [2] Group 2: Water Resource Management - Water resource scarcity is the most prominent contradiction in the Yellow River basin, necessitating strict adherence to the "Four Waters and Four Determinations" principle [2] - A total water usage control system covering the entire basin is to be established to enhance the efficient and economical use of water resources [2] Group 3: Ecological Protection - The ecological fragility of the Yellow River basin requires strengthened water ecological protection and management, including unified water quantity scheduling and ecological flow management [2] - There is a focus on comprehensive governance in areas with high concentrations of coarse sediment, particularly in the Loess Plateau [2] Group 4: Water Rights and Legal Framework - The meeting advocates for deepening water conservancy reforms and exploring the regulation of water rights trading [2] - The implementation of the Yellow River Protection Law and enhanced cross-regional and cross-departmental law enforcement collaboration is emphasized [2]
