A computer programmed water environment capacity calculation method based on a Delft3D model

Abstract

The invention relates to a computer programmed water environment capacity calculation method based on a Delft3D model, and effectively solves the problems that in the early stage, only the water environment capacity can be roughly estimated, meanwhile, the time and space precision is poor, and the experience dependence is large. According to the technical scheme, the method comprises the steps that a certain river channel is selected as a research range, and target section water quality classification is set; setting model boundary conditions including upstream incoming flow and along-the-waybranch boundary conditions; inputting the boundary condition parameters by adopting a Delft3D model system and outputting the boundary condition parameters to obtain a pollutant concentration value when the water quality of the target section meets the requirement; extracting relevant data from the model to calculate the water environment capacity of the pollutants; Due to the fact that the Delft3D model can utilize specific discrete hydrological water quality data, a hydrodynamic field and a water quality field with the time being accurate to second and the space being accurate to meter are output through calculation, automatic calculation is achieved by compiling a computer program, and finally calculation of the water environment capacity of any water body in any time period can be achieved.

Description

technical field [0001] The invention relates to the fields of environmental management such as pollution reduction and total pollutant discharge control, and in particular to a method for calculating water environment capacity by computer programming based on a Delft3D model. Background technique [0002] Environmental capacity is one of the basic theoretical issues of environmental science and one of the important practical application issues of environmental management. Water environmental capacity is an important part of environmental capacity and one of the core contents of the technical system of total capacity. With the transformation of China's water environment management system from concentration control, total target control to total capacity control, and the realization of target water quality management in river basins and red line management of water functional areas to limit pollution, the importance of research on water environment capacity theory and calculati...
