A method and system for flood forecasting and disaster prevention decision-making

Abstract

The invention relates to a flood forecasting and disaster prevention decision-making method and system. Including the historical flood experience database for storing historical flood information, the historical flood analysis and display platform that visually displays the whole process of historical flood in the form of events on the platform, and provides users with timely and comprehensive real-time hydrological monitoring information and real-time flood characteristics A real-time information query platform for information, a historical flood similarity analysis module for finding similar historical flood events according to current real-time conditions to realize flood forecasting, a real-time flood forecast correction module for real-time correction of flood forecasts, and a disaster prevention and scheduling system based on similar historical events Disaster prevention scheduling analysis platform. The present invention makes full use of historical experience data, realizes flood forecasting based on multi-dimensional, real-time correction experience similarity analysis, utilizes similar historical flood events to forecast and analyze current flood conditions, provides basis for disaster prevention scheduling decision-making, and strengthens disaster prevention capabilities.

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
