Urban accumulated water prediction and safety early warning system based on flood drainage model

Abstract

The invention provides an urban accumulated water prediction and safety early warning system based on a flood drainage model. The urban accumulated water prediction and safety early warning system combines the flood drainage model, weather forecast, an accumulated water on-line monitoring system and a decision support system, and achieves support for urban accumulated water prediction and safety early warning. The urban accumulated water prediction and safety early warning system comprises the following steps: (1) combining a pipe network model with a production and confluence model to construct a flood drainage model; (2) depending on a flood drainage model, performing multi-scenario rainfall simulation and warehousing; (3) collecting and reporting real-time rain condition data; (4) calling a multi-scene rainfall bank; and (5) carrying out online prediction and safety early warning on road ponding. The urban accumulated water prediction and safety early warning system based on a flooddrainage model can effectively, accurately and dynamically forecast the flood prevention and drainage conditions of urban ponding-prone points in real time, and can facilitate decision support of a management department.

Description

technical field [0001] The invention relates to the field of smart city management, in particular to an urban waterlogging prediction and safety early warning system based on a drainage model. Background technique [0002] With the development of society, especially the advancement of science and technology, the rapid development of social productivity has been greatly promoted, and people's lives have been greatly improved and improved, especially the rapid development of urbanization, which has made a large number of people in Agglomeration on limited land has formed more and more urban clusters. [0003] With the rapid development of urbanization in our country, many cities have the problem that the planning and construction of urban drainage systems cannot keep up with the rapid expansion of urban scale. As a result, when encountering heavy rainfall, it is easy to form regional water accumulation that is difficult to drain, resulting in urban waterlogging . Urban water...
