Flood prediction and disaster prevention decision-making method and system

Abstract

The invention relates to a flood prediction and disaster prevention decision-making method and system. The system comprises a history flood experience library, a history flood analysis and display platform, a real-time information query platform, a history flood similarity analysis module, a flood prediction real-time correction module and disaster prevention scheduling analysis platform, whereinthe history flood experience library is used for storing history flood information; the history flood analysis and display platform is used for intuitionally displaying overall processes of history floods on the platform in an event form; the real-time information query platform is used for providing timely and all-around real-time hydrologic monitoring information and real-time flood feature information for users; the history flood similarity analysis module is used for searching similar history flood events in contrast to current real-time conditions so as to realize flood prediction; the flood prediction real-time correction module is used for correcting flood prediction in real time; and the disaster prevention scheduling analysis platform is used for carrying out disaster prevention scheduling on the basis of similar history events. According to the method, history experience data is sufficiently utilized, multi-dimensional and real-time correction-based experience similarity analysis of flood prediction is realized, prediction analysis is carried out on current flood conditions by utilizing similar history flood events, basis is provided for disaster prevention scheduling decision-making, and the disaster prevention ability is strengthened.

Description

technical field [0001] The invention relates to the field of flood control, in particular to a method and system for flood forecasting and disaster prevention decision-making based on multi-dimensional, real-time corrected empirical similarity analysis. Background technique [0002] In the field of flood control, it is often necessary to carry out flood forecasting and dispatching for the reservoir channel, and select different forecasting models according to different conditions. The commonly used flood forecasting models include the rainfall-runoff correlation diagram method, the corresponding water level (flow) method, the empirical unit line model, Models, water tank models, etc., these models have a certain range of application scenarios. [0003] The existing technical solutions are introduced as follows: [0004] (1) Rainfall runoff correlation diagram method [0005] Such as figure 1 As shown, the rainfall-runoff correlation diagram method is a simple, practical a...

Problems solved by technology

[0018] Traditional flood forecasting models can solve conventional flood forecasting problems. However, in the face of river flood forecasting that is networked and affected by tidal inversion, due to the complex hydrological mechanism involved, forecasting is difficult, and the forecast calculated by the existing traditional method The accuracy of the results is not high, and the forecast results are poor in reference
