Embodiment Construction

[0027] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0028] like figure 1 As shown, a rain and flood warning method based on rain garden monitoring data is used to analyze the relationship between rainfall and runoff in the area where the rain garden is located and to give early warning of the risk of urban waterlogging, which may include the following steps:

[0029] S1. Obtain the monitoring data of the rain garden, construct the dynamic rain flood model of the area where the rain garden is located, and output the prediction result of the urban waterlogging probability, which can include the acquisition and processing of the original data, the verification data set, the training data set, the construction of the rain flood model, and the △t setting. , node state setting, model training, conditional probability table calculation, model verification, △t setting, node state adjustment, dynamic rainwat...

Abstract

The present invention relates to a rainwater early warning method based on rain garden monitoring data, which may include the following steps: S1. Obtaining rain garden monitoring data, constructing a dynamic rain and flood model in the area where the rain garden is located, and outputting urban waterlogging probability prediction results; S2. City Waterlogging risk analysis, through the analysis of urban waterlogging prediction probability results, identifies and predicts the level of urban waterlogging risk occurrence in the future, and finally realizes the early warning and management of urban rain and flood. The present invention makes full use of the online monitoring data of the rain garden to construct and analyze the rain and flood model and early warning of urban waterlogging risk, so as to provide an effective method for urban rainwater management in the future, and to improve the performance of the rain garden and urban waterlogging in the future. Early warning of security issues provides data and technical support.

Description

technical field [0001] The invention belongs to the field of urban rain and flood management, and particularly relates to a rain and flood warning method based on rain garden monitoring data. Background technique [0002] Rain gardens, also known as bioretention ponds, are one of the Low Impact Development (LID) technologies. They restore the hydrological process through ecosystem services generated by natural elements, control and utilize rainwater runoff from the source, and regulate the regional water cycle. , stormwater management facilities with social, economic, cultural and other multi-functional benefits. It first appeared in the United States in the 1990s and was used for ecological retention, absorption and utilization of rainwater. In recent years, global climate change and rapid urbanization have exacerbated urban water environment problems. Atmospheric deposition and runoff pollution caused by human activities have caused urban water environment pollution. Rain...
