A four-preliminary method to deal with urban rainstorm and waterlogging

Abstract

The present invention discloses a four-prevention method for responding to city rainstorm waterlogging. The method concretely comprises four steps, and comprises: rainstorm waterlogging estimation, rainstorm waterlogging predication, rainstorm waterlogging early warning and rainstorm waterlogging response plan. The four-prevention method for responding to city rainstorm waterlogging realizes the medium and long term estimation, the short-term prediction, the near-real time early warning and the real-time plan service of the city rainstorm waterlogging and provides a set of non-engineering measures capable of actual operation for the city rainstorm waterlogging response.

Description

technical field [0001] The invention belongs to the technical field of urban flood control and disaster reduction methods, and in particular relates to a four-preliminary method for dealing with urban rainstorm and internal waterlogging. Background technique [0002] Affected by global climate change and accelerated urbanization, urban rainstorms and waterlogging occur frequently and widely, causing great harm. The statistics of the "2014 China Flood and Drought Disaster Bulletin" issued by the Ministry of Water Resources of the People's Republic of China show that in 2014, 28 provinces (autonomous regions and municipalities) across the country suffered from flood disasters, of which 125 cities suffered from waterlogging, causing direct economic losses as high as 1573.55 billion. [0003] Nowadays, "Looking at the sea in the city" has become the mantra of urban residents. The process of heavy rainfall in the city can easily cause severe water accumulation in some areas, lea...

Problems solved by technology

[0004] However, there are the following problems in the traditional urban rainstorm waterlogging response methods: on the one hand, it is difficult for the current technology to realize the timing, fixed-point and quantitative accurate forecasting of urban-scale rainstorms, and the conditions of the underlying surface of the city are complex, which can easily cause serious casualties and property loss; on the other hand, the traditional urban rainstorm and waterlogging response mainly relies on uploading and distributing files and telephones and mobile phones as the main means of communication, lack of full mining and efficient use of information, and the rapid development of computer and network technology, making urban rainstorm and waterlogging data Real-time collection, fast transmission and integrated processing become possible, providing support for urban rainstorm and waterlogging response in changing environments

[0005] The response to urban rainstorm and waterlogging involves many departments such as the Urban Flood Control Office, the Meteorological Bureau, and the Hydrological Bureau. In the traditional response methods, different departments often have poor communication of information, work independently, and it is difficult to deal with them in a coordinated manner, which cannot achieve good response effects

In response to frequent urban rainstorms and waterlogging in recent years, many cities have formulated emergency plans for urban rainstorms and waterlogging; however, most of the current plans are in the state of traditional paper, which is difficult to support the rapid response and emergency linkage of urban rainstorms and waterlogging in changing environments. It cannot guide the actual urban rainstorm and waterlogging rescue work, and has great limitations

In addition, in recent years, 30 cities across the country have piloted low-impact development models, hoping to solve the problem of urban rainstorm and waterlogging through the construction of sponge cities. However, the construction of sponge cities requires huge investment and a long cycle, so it is difficult to work in a short period of time.
