Description

Technical field [0001] The invention relates to the field of environmental technology, in particular to a one-dimensional unsteady state river hydrodynamic-water quality simulation method and device. Background technique [0002] River water quality model is a mathematical model that describes the migration and transformation of pollutants in river water bodies. It plays an important role in the application of water quality target management technology in river basins and is an important technical basis for formulating water quality target management plans. The characteristic of the river water quality model is that it can integrate the analysis, evaluation, total control, pollution control and cost-benefit analysis of the river, realize the integration of data and analysis tools, and provide convenience for river water quality management. Using the river water quality model, we can scientifically recognize the degradation and migration of pollutants in the water body and the rel...

AI Technical Summary

Problems solved by technology

In China, conventional steady-state water quality models are generally used to conduct research on unsteady-state river water quality simulation, which brings great uncertainty to water quality target management; however, the current domestic and foreign river water quality models have poor simulation effects and are difficult to adapt to. The status of this highly unsteady river has become an important factor affecting the formulation of river water quality target management programs
