Intelligent river flood forecasting system

Abstract

The invention discloses an intelligent river flood forecasting system which comprises a flood forecasting model (10), a database (20), a water regimen forecasting subsystem (30) and a client (40). The flood forecasting model (10) comprises a single river flood forecasting model and a river system flood forecasting model; for different flood forecasting modes, a neural network is utilized to train and learn the evolution rule of the river flood, so that the downstream flood process is forecasted according to the upstream flood process; and a single river channel and river system flood forecasting model is established by adopting an intelligent algorithm combining an improved BP neural network and a genetic algorithm, wherein the model is used for river channel flood forecasting. A user reads related data information in the database by calling the flood forecasting model to carry out flood forecasting. Compared with the prior art, the method of combining the improved BP neural network introducing the peak value correction coefficient with the genetic algorithm is adopted for forecasting, modeling is reasonable, the algorithm is reliable, precision is high, and the operation speed is greatly improved compared with the prior art.

Description

technical field [0001] The invention relates to the field of emergency disaster prevention and computer application technology, in particular to a river flood intelligent forecasting model system. Background technique [0002] Ice flood monitoring technology is an effective water conservancy information technology, which has important practical significance for protecting people's lives and property. However, at present, ice flood monitoring is still limited to hydrological cross-section observation and on-site inspection, and manual observation has many limitations. However, it is often difficult to collect ice-prevention information to meet the needs of decision-making, and it cannot directly reflect the river and topographic information of the entire region from a global perspective to support decision makers in making reasonable flood control and anti-ice dispatch decisions. There are many and complex factors affecting ice floods. At this stage, it is still necessary to ...
