青春华章丨治水兴邦 以水利之稳托举高质量发展

Core Viewpoint - The article highlights the significance of the Huaihe River to the sea waterway project in Jiangsu, emphasizing its role as a critical infrastructure that supports regional development and flood control efforts [1][4]. Group 1: Infrastructure Development - The Huaihe River to the sea waterway project features Asia's largest water interchange, which is a landmark in water conservancy engineering [4]. - The project utilizes an "upper channel and lower tunnel" design, ensuring that flood discharge and navigation on the Grand Canal do not interfere with each other [5]. - The first phase of the Huaihe River to the sea waterway was completed in June 2003, providing a crucial drainage route that had been absent for over 800 years [5]. Group 2: Flood Control and Benefits - The Huaihe River to the sea waterway has significantly improved flood control, with a design flood discharge capacity of 2,270 cubic meters per second [5]. - In July 2003, the project was activated to manage the largest flood since 1954, successfully discharging 4.38 billion cubic meters of floodwater and preventing the displacement of 300,000 people [5][6]. - The project has enhanced regional drainage standards over an area of 1,170 square kilometers, alleviating flooding issues for over a million residents [6]. Group 3: Ongoing Projects and Future Prospects - The second phase of the Huaihe River to the sea waterway is currently under construction, expanding the flood discharge capacity to 7,000 cubic meters per second [8]. - The second phase aims to improve the flood control standard from a 100-year to a 300-year event, reducing pressure on flood management in the middle reaches of the Huaihe River [8]. - The project is expected to be completed by 2028, further enhancing the region's infrastructure and flood management capabilities [8].
