What is the significance of rainfall station construction?

What is the significance of rainfall station construction? What role does it play in urban flood control? How to do a good job in rainwater collection, distribution and utilization to provide guarantee for storm disaster prevention? These problems need us to explore constantly.

Rainfall gauge station is an important part of urban drainage system, and its importance is self-evident. However, with the development of social economy and the improvement of people's living standards, the awareness of flood and drought disaster prevention is gradually enhanced, especially in recent years, flood disasters caused by various reasons occur frequently, posing a serious threat to the safety of people's lives and property. Therefore, it is particularly important to strengthen the analysis and processing of rainfall observation data.

The traditional method can only determine the amount of rainfall by manually measuring the total amount of rainfall. This calculation method is not only time-consuming and laborious, but also can not accurately reflect the change trend and degree of rainfall in different periods, and can not meet the requirements of modern hydrological forecasting technology. The rainfall station uses modern technology to combine data acquisition equipment with computer for automatic monitoring and data analysis and calculation, which overcomes the defects of existing methods and has obvious advantages. Compared with the manual method, the rainfall station has the following advantages:

First, various rainfall standards can be designed according to the characteristics of different regions;

Second, it is easy to manage and maintain;

Third, it is easy to realize automatic control without manual collection;

Fourth, it is conducive to timely grasp the weather dynamics and predict the possible disasters in the future.

Nowadays, rainfall stations have become an indispensable technical means for urban planning, water resource scheduling, urban drainage and waterlogging prevention, and are also widely used in municipal infrastructure projects and the production process of large enterprises, playing a very important guiding role. At present, all major cities in China have established relatively complete rainfall stations to achieve real-time detection, monitoring and early warning
