Problems solved by technology

Although the first method is simple, the constructed pipeline is too rough. Although the second method is accurate, the coupling of the two software is too complicated and difficult, and the technical requirements are too high
[0004] At present, the simulation of river system mostly uses expensive commercial software, and SWMM is generally used for the simulation of rainwater system. It has not been seen to use SWMM to simulate the river, let alone the simulation of the water circulation of the river.

Embodiment Construction

[0012] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0013] A method of using SWMM software to simulate the river water circulation, using the following steps:

[0014] 1) Model import:

[0015] 1) Simplify the river course into a line, draw the river course plan with a polyline in CAD, end the upper polyline at the turning point of the river course, and start the lower polyline; then name the CAD drawing of the river course and save it as "AutoCAD R12 / LT2DXF (*.dxf)" format file;

[0016] 2) Use the "Dxf2EPANET" software to convert the dxf format file obtained from step 1) into an inp format file; then import the inp format file into the SWMM software, and the start point, inflection point and end point of the river course appear on the SWMM software interface.

[0017] The specific import and export method is: open the Dx...

Abstract

The invention discloses a method for simulating riverway water quantity circulation by using SWMM software. The method adopts the steps that 1, a riverway is simplified into lines, and a riverway plane graph is drawn in CAD and saved as a file in the format of 'AutoCAD R12/LT2DXF(*.dxf)'; 'Dxf2EPANET' software is used for converting the file in the dxf format into a file in the inp format, and the file in the inp format is imported into the SWMM software; 2, in the SWMM software, a starting point, inflection points and an ending point of the riverway are sequentially connected through pipe duct straight lines from upstream to downstream; 3, in the SWMM software, the riverway attribute is input into a riverway model, and then river depths on the starting point, the inflection points and the ending point of the riverway are input into the riverway model; a dynamic wave is selected in a menu, and the duration in a time step menu is set below 60 s; water pumps are arranged in riverway segments needing circulation. The method is simple, fast and low in cost.

Description

Technical field [0001] The invention relates to a method for simulating river water circulation by using SWMM software, which is suitable for the simulation of rivers with poor fluidity that need to improve water quality. Background technique [0002] SWMM (Storm Water Management Model) is a dynamic rainfall-runoff simulation software released by the U.S. Environmental Protection Agency in 1971. It is widely used in the planning, analysis and analysis of rainwater runoff, combined pipes, sewage pipes and other discharge systems in urban and non-urban areas. Designed, it can simulate water quantity and water quality, and can also simulate single field and continuous rainfall. It is a very versatile and free software. [0003] There are usually two methods to construct traditional SWMM pipes. One is to draw directly in the software, or first import the background image and then draw in the software; the other is to couple GIS and SWMM, just import it. Although the first method is s...
