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 Viewpoint - The "What is China: Yellow River Safety" online theme promotion event was launched in Zhengzhou, Henan Province, highlighting the cultural and ecological significance of the Yellow River in shaping national identity and cultural confidence [1]. Group 1: Cultural and Ecological Significance - The Zhengzhou Yellow River Cultural Park, established from the 1970s, serves as a vital cultural and ecological hub, marking the starting point of the Yellow River's "suspended river" and the boundary between the Loess Plateau and the Yellow River's middle and lower reaches [2]. - The park features the "Three Bridges Convergence" site, showcasing a railway bridge museum that reflects a century of railway evolution in China, alongside a scenic area with rich flora and fauna [3]. - The park has transformed from barren land to a thriving cultural theme park, integrating educational travel, scientific education, geological relics, and Yellow River culture, benefiting the local community [5]. Group 2: Environmental Management and Technological Advancements - The Zhengzhou Yellow River Cultural Park has successfully greened over 8,000 acres of barren mountains, achieving a forest coverage rate of over 90%, thus providing a robust ecological barrier for the Yellow River [6]. - The Yellow River in Zhengzhou, spanning 160 kilometers, is a critical area for flood prevention, with advanced technology being employed for real-time monitoring and decision-making in flood management [7]. - The establishment of the Yellow River flood prevention intelligence system has streamlined communication and response times, allowing for automated flood level assessments based on real-time water flow data [7]. - The "Model Yellow River," an 800-meter long physical model, aids in providing technical support for flood management decisions and strategies [9].
