Abstract

The invention relates to a water environment analysis method based on a geographic information system and a Delft3D-FLOW calculation engine. The water environment analysis method comprises the steps that a software system framework is built through a GIS platform; a Delft3D mesh file format is analyzed; a configuration file MDF file format of the Delft3D-FLOW and meanings of multiple parameters in the configuration file MDF file format are analyzed, and a human-computer interaction configuration interface is developed for configuring the multiple parameters under the GIS platform; a model is built, configuration tasks of a plurality of environmental elements are completed through GIS operation; a configuration result is output as a file format which can be identified by the mathematical calculation engine, and the calculation engine is called to conduct calculation; a calculation result file format is analyzed, a file is read under the GIS platform and processed into a raster image with space coordinates through the image processing technology, and the raster image is loaded into the GIS platform for display. The water environment analysis method combines the mathematical model with spatial and geographic information, thereby improving analysis accuracy. The invention further provides a water environment analysis system based on the geographic information system and the Delft3D-FLOW calculation engine.

Description

technical field

[0001] The invention relates to the field of computer technology, in particular to a water environment analysis method and system based on a geographic information system and a Delft3D-FLOW computing engine. Background technique

[0002] At present, water environment simulation technology is an effective tool for predicting and analyzing various complex problems in the real water environment by using a series of mathematical models in a virtual environment, and can provide a strong scientific basis for solving environmental problems. Currently commonly used water environment simulation analysis systems such as EFDC and DELFT3D use Fortarn language to develop calculation engines.

[0003] Specifically, DELFT3D is a complete three-dimensional hydrodynamic-water quality model system developed by Deltares in the Netherlands, including water flow (FLOW), particle tracking (PART), water quality (WAQ), ecology (ECO) and other components. Technically, DELFT3D-FLOW T...
