Why is there serious water accumulation in Weihui flood season in Henan Province?

Introduction: After the flood in Zhengzhou, Henan Province was effectively alleviated, the flood in Weihui, Henan Province became more serious. And it lasts for a long time, so why is there more water than Zhengzhou? The reason has to arouse people's thinking. Many netizens said that the reason for the water accumulation in Weihui, Henan Province was that the dredging work was not done well, or the degree of attention was not high, which led to low work efficiency and serious water accumulation.

I. Geographical location One of the explanations given by residents in Weihui, Henan Province for the serious flood is that the geographical location is easy to accumulate water. Wei Hui belongs to the intersection of Weihe River and Mengjiangnv River. The terrain is not only low-lying, but also a gathering area for incoming water. Once there is a rainstorm or flood, it is easy to make the accumulated water difficult to solve. For this objective reason, many netizens said it was acceptable. Because geographical location is a fact that people cannot change the day after tomorrow, many people also speculate that geographical location may be one of the important reasons for the serious water accumulation.

Second, a lot of rainfall We all know that even in low-lying areas, if there is no heavy rainfall, it will not lead to serious water accumulation. It is estimated that the average rainfall in this area is about 550 mm, which is a once-in-a-millennium rainstorm for local residents. Of course, it is also one of the objective reasons that people can't change this extreme weather. The rainfall is heavy and the terrain is low, so it is difficult to drain the accumulated water for a while. From time to time, the land is unfavorable, which leads to serious water accumulation in Weihui, Henan.

Three. One of the reasons for the low drainage efficiency of related facilities in Weihui, Henan Province is that the drainage facilities are relatively backward. Compared with Zhengzhou, the drainage facilities in Weihui, Henan Province are not advanced and perfect, and the related disaster relief measures and facilities are not as perfect, timely and efficient as Zhengzhou, which also leads to serious water accumulation. In addition, serious water accumulation is inseparable from the effective management of the local government. If complete drainage measures or related treatment measures are formulated locally, it may be alleviated to some extent.
