Core Viewpoint - The Longmen Hydrological Station, established in 1934, is undergoing a significant transformation towards intelligent monitoring, enhancing its operational efficiency and data accuracy while continuing to safeguard the Yellow River [1][18]. Group 1: Station Overview - The Longmen Hydrological Station is a crucial control station for the Yellow River, located on a cliff, and is the only hydrological station built in such a manner [1]. - The station has undergone six relocations throughout its history, indicating its adaptability and importance in monitoring the river [5]. Group 2: Technological Advancements - Modern equipment such as video flow measurement systems and unmanned boats have replaced traditional methods, allowing for more accurate and efficient data collection [8][9]. - The introduction of the Yellow River Hydrological Digital System has enabled real-time monitoring and data visualization across multiple hydrological stations [16]. Group 3: Operational Changes - The station's operational approach has shifted from reliance on cable cars for measurement tasks to fully automated systems, significantly reducing the need for manual labor [3][8]. - During non-flood periods, the station requires only 3 to 4 personnel for monitoring, compared to 13 during emergency situations [19]. Group 4: Workforce and Training - The average age of the workforce at the station is 32, with a significant number of young professionals contributing to the modernization efforts [18]. - The station emphasizes the importance of knowledge transfer between experienced workers and younger staff to maintain traditional skills alongside modern technology [21].

Core Viewpoint - The Longmen Hydrological Station, established in 1934, is undergoing a significant transformation towards intelligent monitoring, enhancing its role in safeguarding the Yellow River [1] Group 1: Station Overview - The Longmen Hydrological Station is a crucial control station for the Yellow River, located on a cliff and accessible only via a cable car [1][3] - The station has modernized its monitoring methods, moving away from traditional cable cars for hydrological measurements to advanced technologies [4][12] Group 2: Technological Advancements - The station now employs modern equipment such as radar water level gauges, remote-controlled sediment samplers, and video flow measurement systems, which have revolutionized its monitoring capabilities [12][14] - The introduction of video flow measurement systems has replaced traditional float methods, allowing for real-time monitoring of water surface flow rates [6][12] Group 3: Operational Efficiency - The station's operational efficiency has improved significantly, with the ability to conduct flow measurements every three to four days during stable water levels, compared to previous manual methods [12][13] - The average age of staff at the station is 32, indicating a youthful workforce that is adept at utilizing modern technology [12] Group 4: Training and Knowledge Transfer - The station emphasizes the importance of knowledge transfer between older and younger staff, ensuring that traditional skills are not lost amidst modernization [14][15] - Training initiatives, such as skill competitions, are organized to bridge the gap between generations of hydrologists [14]
