In 1931, the highest water level in the Wuhan section of the Yangtze River was only 16.35 meters?A response is here

"There are two bronze medals recorded on the exterior wall of Jianghan Guan. One of the brands of which recorded the highest water level in 1931 is 53.65 feet, and the converted to only 16.35 meters. Is this accurate?" Recently, Mr. Huang, a citizen, left a message on the Wuhan city. Write down the above doubts.

Mr. Huang was 75 years old. According to his introduction, he took a ferry in Jianghan Pass in his memory. He once saw the bronze medal recorded on the outer wall of Jianghanguan, which recorded the highest water level in the Wuhan section of the Yangtze River. But at the time, he did not pay attention to the specific data.

About 3 years ago, when Mr. Huang passed Jianghan Guan, he saw the bronze medal with the highest water level in Jianghan Guan in the flood season of 1931 and 1954 in the flood of 1931 and 1954. He checked it carefully, but found that the water level data in 1931 was "a bit problematic."

"The water level marked on the brand is 53.65 feet, which is less than 20 meters in public, and the highest water level in other places is 28.28 meters in 1931." Mr. Huang is a science and engineering background, which is more sensitive to numbers. It was found that 53.65 feet was only 16.35 meters. "Old Wuhan people have heard the elders say that in 1931, the floods entered the city, and Jianghan Road was flooded. How could it only be more than ten meters, is it a record error or the calculation method is different?"

On the morning of the 20th, a reporter from the Yangtze River Daily found two bronze medals described by Mr. Huang on the outer wall on the side of Linjiang Avenue on the side of Linjiang Avenue. A high bronze medal recorded "August 18, 1954, the highest flood position (with Wusong as zero) 29.73 meters"; the lower bronze medal recorded the highest water level on August 19, 1931 was "53.65 feet" Essence

Subsequently, the reporter rushed to the "water level" sculpture located in Sanyang Gate of Hankou Jiangtan. The sculpture records the highest water level in Wuhan Pass in 4 years of 1931, 1954, 1998, and 2020, and it is marked with "Frozen Wusong Field", of which the water level was recorded at 28.28 meters in 1931.

In response to citizens' doubts, the relevant person in charge of the Jianghan Guan Museum stated that the bronze medal hanging from the outer wall of Jianghanguan was prepared by the Jianghanguan Museum, and it was copied by the bronze medal in the past, and it was also used in historical data. The highest water level in 1931 was 53.65 feet, which was the data recorded in the archives of the Jianghan Taxation Department. Before making bronze medals, experts were also demonstrated by experts. The data was no problem. A file on a report on floods also records the highest water level data of Hankou before 1931, and the units used are feet. For example, it was 43.9 feet in 1927, which belongs to the normal age. It was 48.9 feet in 1926, which was an abnormal age. "So, it is impossible to be wrong with the original record data."

The person in charge speculated that the base surface that measured the water level at that time was different from today, so the data was inconsistent with today. According to relevant information, after the founding of the People's Republic of China, Wuhan hydrological monitoring uses the Wusongkou Yangtze River water level as the base. In Jianghanguan's historical data, the base surfaces used during data measurement such as "53.65 feet" were not recorded. "Jianghan Guanwai records the bronze medal in the 1931 water level, and it has not marked‘ with Wusong as zero ”like other bronze medals."
