Embodiment Construction

[0027] figure 1 The schematic diagram showing the one-dimensional unsteady state river hydrodynamic-water quality simulation process. The simulation process can be used to simulate and analyze the hydrodynamic and water quality change laws of the artificially regulated and unsteady river water ecological process. In terms of hydrodynamics, it is suitable for one-dimensional hydraulic calculations of stable and unsteady river flows, and can generate various analysis charts such as cross-sectional flow and water level process curves. In terms of water quality, it can be used to simulate the water quality simulation mathematical model of unsteady rivers (artificial regulation, cut-off, unconventional water supply, etc.), and it can provide scientific water quality simulation technical methods for the water quality target management of unsteady rivers; River environmental pollution analysis and prediction of various water quality conditions caused by human pollution; it can simulat...

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...
