Dynamic water environment management method

Abstract

The invention discloses a dynamic water environment management method. The method comprises the following steps: firstly, collecting and monitoring water environment related information and analyzing water quality and specific pollutants; calibrating / training a water body inlet boundary condition model; then calibrating or estimating the roughness of the hydrodynamic water quality model and the degradation coefficient of pollutants; forecasting the flow or water quality data on the inlet boundary of the research area by adopting the calibrated / trained boundary condition model in combination with other related information; and finally, utilizing the determined or estimated roughness of the hydrodynamic water quality model, the degradation coefficient of pollutants and a water body boundary condition forecast result, and combining with water system section data and latest monitored point source emission measured data to forecast the hydrodynamic water quality of the research area; carrying out water quality early warning and discharge capacity emission reduction feedback according to the forecast result. According to the method, a large amount of actually measured data and information are included, and dynamic monitoring and dynamic prediction of the water environment and more scientific dynamic water environment management are achieved.

Description

technical field [0001] The invention relates to the technical field of water environment monitoring and management, in particular to a dynamic water environment management method. Background technique [0002] Different water bodies have different functional zoning, so the water quality standards for different water bodies are also different. When the sewage outlets and discharge volume involved in the water body are constant, the self-purification ability of the water body is also different due to different water inflows, flow rates, and water body problems, so the environmental capacity of the water body also changes from time to time. In fact, the amount of sewage discharged from water sewage outlets will vary depending on the output of the enterprise. Therefore, for a specific area, the water quality and pollution-holding capacity of its water body are also constantly changing. Therefore, it is necessary to dynamically predict the water environment, so as to realize the...

Problems solved by technology

Therefore, it is necessary to dynamically predict the water environment, so as to realize the dynamic management of sewage discharge. However, the current management of sewage discharge in my country is based on the total amount of sewage discharge, which has been unable to meet the needs of fine management of water body and water environment.
