Embodiment Construction

[0042] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. While the invention will be described in conjunction with the preferred embodiments, it will be understood that it is not intended to limit the invention to the described embodiments. On the contrary, the invention is to cover alternatives, modifications and equivalents, which may be included within the scope of the invention as defined by the appended claims.

[0043] The overall structure of the system is as figure 1 As shown, the specific implementation steps are as follows:

[0044] Step 1. Build a historical water regime database

[0045] Through in-depth research on urban water regime data, it can be found that urban water regime data mainly includes two types of codes and values, such as figure 2 In the shown river channel water regime table, the river feature code, water potential, tidal current method, volumetric method, and velocity measurem...

Abstract

The invention discloses an urban flood prevention decision support system based on a big data technique. The urban flood prevention decision support system comprises steps as follows: S1, establishment of a historical water regimen database; S2, acquisition and storage of real-time water regimen data; S3, establishment of a combined water level prediction model; S4, real-time water regimen display and water level prediction; S5, statistical analysis of historical water regimen data. The system has the benefits as follows: the water level in 1-6 hours can be effectively predicted, so that decision support is provided for flood control and disaster reduction work when the urban flood season approaches. The system adopts a distributed database HBase and can effectively store mass water regimen data and cope with rapid growth of data, besides, a big data analysis engine Impala is used for real-time processing and analysis on mass historical water regimen data, intrinsic value of the historical data is explored with a data visualization technology and information guidance is provided for flood prevention work.

Description

technical field [0001] The invention relates to an urban flood control decision support system, more specifically, it relates to an urban flood control decision support system based on big data technology. Background technique [0002] In recent years, with the rapid development of the economy, the urbanization process in our country has been showing a trend of accelerated development, the number of cities is increasing, and the scale of cities is also expanding. While the process of urbanization promotes the progress of social civilization, it also brings many problems and challenges to cities, and urban flood disasters are one of them. Whenever the flood season comes, news of cities suffering from floods continues to appear in the newspapers. [0003] Due to the extremely serious consequences of sudden flood disasters in cities, people have made a lot of efforts to resist floods. Before the 1960s, people focused on engineering measures in the work done to resist floods. ...
