Embodiment Construction

[0021] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings and specific conditions.

[0022] Depend on figure 1 Given, the specific implementation of the method of the present invention includes the following steps: (1) For the predicted river, use the function of "add path" in Google Earth to draw the specific boundary of the predicted river, and export the boundary as a . kml format file;

[0023] (2) Import the .kml file of the predicted river boundary into ArcGIS software, and convert the predicted river boundary into points through the "Feature Vertices To Points" tool in "Data Management Tools"; then use the "Projections and Transformations" tool to convert The WGS 1984 coordinates of the points are converted into WGS-1984-Alberts coordinates in meters; the converted predicted river boundary point coordinates are stored as a text file in .p2d format;

[0024] (3) Import the .p2d fi...

Abstract

The invention aims to provide a river water quality prediction method. The method includes the steps that a specific boundary of a to-be-predicted river is depicted; a .kml format file of the predicted river boundary is converted into a point; the WGS 1984 coordinates of the point are converted into coordinates with meter as the unit; the converted to-be-predicted river boundary point position coordinates are stored; grid division is carried out on the predicted river by using CVLGrid1.0 software, and the divided predicted river grid is exported; a grid file of the to-be-predicted river is imported into an EFDC-Explorer; on the basis of establishing a hydrodynamic model, a water quality model of the predicted river is established; real-time monitored flow and water quality data of the flow boundary of the predicted river are imported into the water quality model, the water quality distribution situation of the to-be-predicted river is simulated within a period of time, and water quality prediction of the to-be-predicted river is achieved. The method is unique, easy to operate and apply, accurate in prediction effect and beneficial to ecological environment protection of rivers, and has remarkable economic and social benefits.

Description

technical field [0001] The invention relates to environmental protection, in particular to a river water quality prediction method for river water quality prediction. Background technique [0002] Water quality prediction is based on the actual data of water quality, using the water quality model to infer the future changes of the water quality of the water body or a certain location of the water body. It can provide guidance and support for water environment management. [0003] Water quality model, also known as water quality mathematical model, is a mathematical description of the change law of water quality. It can be used to predict water quality, study water pollution and self-purification, and control sewage discharge. [0004] The EFDC model is an open source model supported by the US Environmental Protection Agency (EPA) and developed by the Virginia Institute of Oceanography based on the integration of multiple mathematical models. EFDC_Explorer is a software wi...
