This group of people is doing a "physical examination" for the Huangpu River water. There is a major discovery ...

The Huangpu River was the last tributary before the Yangtze River remitted into the East China Sea. It was the largest river in Shanghai and the golden waterway and transportation artery of Shanghai. Like people, Huangpujiang "do medical examinations" every year.

On September 19, the reporter learned from the China Communications Bureau Dahua Technology Company that with the final section of the last test section upstream of the Huangpu River, the full section of the Hongpu River Hydrological Testing Project for nearly half a month was successfully finalized.

"Hydrological measurement is essentially to give the water in the Huangpu River regularly a comprehensive" physical examination "every year. We found that with the maintenance and governance of the Huangpu River channel in recent years Yang Zhi, secretary of the party committee and chairman of the technology company.

Huangpu River will conduct two hydrological tests twice a year, divided into floods and dry season, of which each season is divided into three tide segments: big, middle and small. The tide tide power is the strongest, the tide is the largest, the tide tide is the weakest, and the tide is the smallest, and the middle tide is between the two. The three different types of different tide types are to comprehensively monitor Huangpu River's water -flowing Saudi properties under different tide power, improve the representativeness and breadth of data, and better serve the data of water -related projects, shipping, channel maintenance and dredging and other undertakings. Essence

In this sampling, the work boat first came to the designated measurement area near the Sanqiao of Songpu, Huangpu River. The staff used a 1 -liter of volume -accumulated horizontal water pickup to "take water" from the different depth of the center of the river and poured into the container. "The sampling point must be sampled once a hour, and the" physical examination "needs to be completed 30 times for 29 consecutive hours." Wang Huaili, deputy general manager of Shanghai Dahua Technology Company, told reporters that the reason for such a long time is to go through the "two rose of the tide water. "The two falls", the data obtained in this way is the most comprehensive, and the water taken out will be sent to the laboratory to analyze the water quality composition.

At present, the use of the Huangpu River hydrology is used in international first -class instruments. Compared with traditional instruments, it has the advantages of simple operation, short testing time, high work efficiency, rich data volume, and high accuracy. For example, acoustic Doppler flow velocity section, it can collect data such as water flow speed and direction, water temperature, and water flow at different times in real time. The work efficiency is equivalent to multiple traditional flow velocity direction instruments.

The Huangpu River hydrological test is carried out regularly every year. One is to master the trend of Huangpu River, mud Saudi, terrain and landforms, and the evolution of the riverbed. Construction, water environmental protection, and flood control have an important role. The third is to effectively promote the water safety, water ecology, water landscape and water culture on both sides of the riverside, and further enhance the intelligent management level of both sides of the riverside and the comprehensive development value of Huangpu River. It will effectively help help The two sides of the Huangpu River has become a world -class waterfront area and a centralized exhibition area for the development energy level of the international metropolis.

Xu Wanyi, Secretary of the Party Committee and Director of the Shanghai Port and Airlines Business Development Center, said: "In the next step, we plan to develop the relevant hydrological test data of Huangpu River in the direction of visual and intelligent, thereby improving the intelligent management level of the channel."
