A current flood consistency processing method and system based on multi-source information

Abstract

The present invention proposes a current flood consistency processing method and system based on multi-source information. By combining the characteristics of natural floods and at least one attribute such as the impact of current human activities, using computer big data processing and analysis technology to analyze hydrological big data, the actual The expression form of flood characteristics can provide the optimal decision-making basis for flood control and improve the efficiency of control. By combining the attributes of multi-source information, this application constructs a comprehensive database that integrates multi-source information, which not only captures the impact factors of flood changes more realistically and accurately, but also balances the deviation problem generated in the actual scheduling process. In addition, based on the support vector machine data mining method, the SCE-UA global optimization algorithm is coupled with the data cross-validation to optimize the training of the data analysis model, which can not only quickly converge to obtain the global optimization model, but also stably improve the intelligence Simulation accuracy for data mining.

Description

technical field [0001] The invention relates to a current flood consistency processing method and system based on multi-source information, in particular to the technical field of hydrological big data mining and analysis. Background technique [0002] Flood characteristics are the basic basis for basin comprehensive planning, professional planning and water engineering planning, design, construction, operation and management, as well as decision-making basis for basin flood control, water resources dispatching and comprehensive management. As the impact of human activities intensifies, such as the construction of cascade reservoirs and diversion and diversion projects, the comprehensive improvement of river channels, and the development of sluices and dams, etc., will lead to significant changes in the characteristics of the river channel, which will affect the flood process, resulting in the actual operation of the project. There may be large differences in the designed fl...

AI Technical Summary

Problems solved by technology

However, with the rapid development of my country's social economy, the demand for water in the basin continues to increase, especially the successive completion of cascade water projects, and the multi-block joint regulation represented by the cascade reservoir group has become normal, resulting in the diversification of the impact of human activities. Increased the complexity of water project joint dispatching simulation; and a single water project control simulation can no longer fully reflect the impact of human activities

Not only that, the actual regulation of water projects over the years has proved that because the actual hydrological conditions are often different from the design conditions, the actual dispatch of water projects is not carried out in an impartial manner in accordance with the dispatching regulations. It is impossible to accurately reproduce the existing flood characteristics, which will affect the flood control and benefit benefits of the project
