Problems solved by technology

[0006] The present invention aims to provide a fast water quality simulation based on a water environment coupling model for the single water environment model that does not fully consider pollution sources and hydrodynamic factors, loosely coupled models are not systematic, complex and difficult to operate, and low in simulation efficiency. The method and system integrates multiple elements and the whole process of water pollution simulation, simplifies the river water quality modeling process, and can realize high-precision and fast-efficiency water quality prediction

Embodiment Construction

[0075] The present invention is further described below in conjunction with the accompanying drawings, and the process is as follows figure 1 shown.

[0076] (1) Prepare terrain data and generate a two-dimensional terrain grid:

[0077] Collect the geographic plane coordinates of the borders on both sides of the river and the spatial geographic coordinates of the elevation scatters (see figure 2 Topographic data collection schematic), extract the range of the simulated river channel, ensure that the scattered points of the river bank are uniform and the connection lines are smooth, avoid sharp mutation points, and draw the control section lines, so that the control sections are distributed as evenly as possible at the change of the river regime. image 3 Shown is the line drawing of the river section of Jinshan Lake in Huizhou City, and the grid terrain simulation results are shown in Figure 4 .

[0078] (2) Establish a model data frame:

[0079] River hydrology and wate...

Abstract

The invention discloses a method and system for quickly simulating water quality based on a water environment coupling model. Simple terrain data is prepared from measured data or remote sensing images to generate a two-dimensional terrain grid; a standardized data frame is built, and non-points are considered as a whole. sources, point sources, and internal sources, as well as the whole process of hydrodynamics and water quality migration and transformation; the reasonable value range and adjustment method of recommended parameters provide a set of ideas for rapid verification of coupling models; Accurately manage and control the target water environment capacity calculation model, and realize the visual expression of water quality simulation and analysis results. The water quality simulation method and system provided by the present invention consider many types of pollution sources and a comprehensive physical mechanism process. Compared with the traditional water quality loosely coupled simulation method in data processing, it is simpler and more efficient, and the obtained water quality prediction results are also more accurate. It can serve Practical management of water environmental quality.

Description

technical field [0001] The invention belongs to the field of environmental water conservancy and computational mathematics, in particular to a water quality rapid simulation method and system based on a water environment coupling model. Background technique [0002] Under the situation of rapid social and economic development, strong human activities have accelerated the rate of change in the water environment, and also aggravated the complexity and uncertainty of the factors and directions of changes in the water environment. A single water quality model has been unable to describe the water environment affected by multiple pollution source variables. The complex migration and transformation process cannot meet the high-precision requirements of water quality simulation. [0003] The high-level integration and coordinated development of the whole process of hydrology, hydrodynamics and water quality are realized through multi-model coupling, and the multi-element whole proc...
