Abstract

The invention relates to a sudden water pollution forward and reverse coupling traceability method and system. The method comprises the following steps: establishing a river channel one-dimensional forward water quality simulation model according to obtained mechanical parameters and water quality parameters; according to the one-dimensional forward water quality simulation model of the river channel, measuring and calculating each monitoring index by using a reverse optimization traceability model, constructing the one-dimensional forward water quality simulation model of the river channel, using the reverse optimization traceability model for measurement and calculation, and carrying out a Bayesian updating process, so that multi-information fusion is realized. According to the method, different observation information can be reasonably dominated and used, and redundancy or complementation of multi-source information in space or time is combined to obtain consistent explanation of a measured object, so that the uncertainty of a water environment is overcome, the accuracy of water pollution traceability is improved, and multiple solutions of the water pollution traceability problem are realized.

Description

technical field [0001] The invention relates to the technical field of multi-source data collection, in particular to a method and system for forward and reverse coupling source tracing of sudden water pollution. Background technique [0002] Water is the source of life and the primary basis for maintaining the sustainable development of the ecological environment. With the advancement of industrialization and new urbanization, accidental leakage and illegal discharge of industrial enterprises threaten the water environment of small and medium-sized rivers and canals. Timely and accurate identification of pollution sources is of great importance. It is of great significance to deal with sudden water pollution incidents. [0003] The Pollutant Source Detection problem, as a typical inverse problem of environmental hydraulics, has been studied in many fields. Scholars at home and abroad have studied a variety of river water pollution accident traceability algorithms, and gener...
